-README:
- This file should be located at the top of the OpenJDK Mercurial root
- repository. A full OpenJDK repository set (forest) should also include
- the following 7 nested repositories:
- "jdk", "hotspot", "langtools", "nashorn", "corba", "jaxws" and "jaxp".
-
- The root repository can be obtained with something like:
- hg clone http://hg.openjdk.java.net/jdk9/jdk9 openjdk9
-
- You can run the get_source.sh script located in the root repository to get
- the other needed repositories:
- cd openjdk9 && sh ./get_source.sh
-
- People unfamiliar with Mercurial should read the first few chapters of
- the Mercurial book: http://hgbook.red-bean.com/read/
-
- See http://openjdk.java.net/ for more information about OpenJDK.
-
-Simple Build Instructions:
+Welcome to OpenJDK!
+===================
- 0. Get the necessary system software/packages installed on your system, see
- http://hg.openjdk.java.net/jdk9/jdk9/raw-file/tip/README-builds.html
-
- 1. If you don't have a jdk8 or newer jdk, download and install it from
- http://java.sun.com/javase/downloads/index.jsp
- Add the /bin directory of this installation to your PATH environment
- variable.
+For information about building OpenJDK, including how to fully retrieve all
+source code, please see either of these:
- 2. Configure the build:
- bash ./configure
+ * common/doc/building.html (html version)
+ * common/doc/building.md (markdown version)
- 3. Build the OpenJDK:
- make all
- The resulting JDK image should be found in build/*/images/jdk
-
-where make is GNU make 3.81 or newer, /usr/bin/make on Linux usually
-is 3.81 or newer. Note that on Solaris, GNU make is called "gmake".
-
-Complete details are available in the file:
- http://hg.openjdk.java.net/jdk9/jdk9/raw-file/tip/README-builds.html
+See http://openjdk.java.net/ for more information about OpenJDK.

-<h2>Use of Mercurial</h2>
-
-<p>The OpenJDK sources are maintained with the revision control system
-<a href="http://mercurial.selenic.com/wiki/Mercurial">Mercurial</a>. If you are new to
-Mercurial, please see the <a href="http://mercurial.selenic.com/wiki/
-BeginnersGuides">Beginner Guides</a> or refer to the <a href="http://hgbook.red-bean.com/">Mercurial Book</a>.
-The first few chapters of the book provide an excellent overview of Mercurial,
-what it is and how it works.</p>
-
-<p>For using Mercurial with the OpenJDK refer to the <a href="http://openjdk.java.net/guide/
-repositories.html#installConfig">Developer Guide: Installing
-and Configuring Mercurial</a> section for more information.</p>
-
-<p><a name="get_source"></a></p>
-
-<h3>Getting the Source</h3>
-
-<p>To get the entire set of OpenJDK Mercurial repositories use the script
-<code>get_source.sh</code> located in the root repository:</p>
-
-<pre><code> hg clone http://hg.openjdk.java.net/jdk9/jdk9 YourOpenJDK
- cd YourOpenJDK
- bash ./get_source.sh
-</code></pre>
-
-<p>Once you have all the repositories, keep in mind that each repository is its
-own independent repository. You can also re-run <code>./get_source.sh</code> anytime to
-pull over all the latest changesets in all the repositories. This set of
-nested repositories has been given the term "forest" and there are various
-ways to apply the same <code>hg</code> command to each of the repositories. For
-example, the script <code>make/scripts/hgforest.sh</code> can be used to repeat the
-same <code>hg</code> command on every repository, e.g.</p>
-
-<pre><code> cd YourOpenJDK
- bash ./make/scripts/hgforest.sh status
-</code></pre>
-
-<p><a name="repositories"></a></p>
-
-<h3>Repositories</h3>
-
-<p>The set of repositories and what they contain:</p>
-
-<ul>
-<li><strong>. (root)</strong> contains common configure and makefile logic</li>
-<li><strong>hotspot</strong> contains source code and make files for building the OpenJDK
-Hotspot Virtual Machine</li>
-<li><strong>langtools</strong> contains source code for the OpenJDK javac and language tools</li>
-<li><strong>jdk</strong> contains source code and make files for building the OpenJDK runtime
-libraries and misc files</li>
-<li><strong>jaxp</strong> contains source code for the OpenJDK JAXP functionality</li>
-<li><strong>jaxws</strong> contains source code for the OpenJDK JAX-WS functionality</li>
-<li><strong>corba</strong> contains source code for the OpenJDK Corba functionality</li>
-<li><strong>nashorn</strong> contains source code for the OpenJDK JavaScript implementation</li>
-</ul>
-
-<h3>Repository Source Guidelines</h3>
-
-<p>There are some very basic guidelines:</p>
-
-<ul>
-<li>Use of whitespace in source files (.java, .c, .h, .cpp, and .hpp files) is
-restricted. No TABs, no trailing whitespace on lines, and files should not
-terminate in more than one blank line.</li>
-<li>Files with execute permissions should not be added to the source
-repositories.</li>
-<li>All generated files need to be kept isolated from the files maintained or
-managed by the source control system. The standard area for generated files
-is the top level <code>build/</code> directory.</li>
-<li>The default build process should be to build the product and nothing else,
-in one form, e.g. a product (optimized), debug (non-optimized, -g plus
-assert logic), or fastdebug (optimized, -g plus assert logic).</li>
-<li>The <code>.hgignore</code> file in each repository must exist and should include
-<code>^build/</code>, <code>^dist/</code> and optionally any <code>nbproject/private</code> directories. <strong>It
-should NEVER</strong> include anything in the <code>src/</code> or <code>test/</code> or any managed
-directory area of a repository.</li>
-<li>Directory names and file names should never contain blanks or non-printing
-characters.</li>
-<li>Generated source or binary files should NEVER be added to the repository
-(that includes <code>javah</code> output). There are some exceptions to this rule, in
-particular with some of the generated configure scripts.</li>
-<li>Files not needed for typical building or testing of the repository should
-not be added to the repository.</li>
-</ul>
-
-<hr />

-
-<h2>Building</h2>
-
-<p>The very first step in building the OpenJDK is making sure the system itself
-has everything it needs to do OpenJDK builds. Once a system is setup, it
-generally doesn't need to be done again.</p>
-
-<p>Building the OpenJDK is now done with running a <code>configure</code> script which will
-try and find and verify you have everything you need, followed by running
-<code>make</code>, e.g.</p>
-
-<blockquote>
- <p><strong><code>bash ./configure</code></strong> <br />
- <strong><code>make all</code></strong></p>
-</blockquote>
-
-<p>Where possible the <code>configure</code> script will attempt to located the various
-components in the default locations or via component specific variable
-settings. When the normal defaults fail or components cannot be found,
-additional <code>configure</code> options may be necessary to help <code>configure</code> find the
-necessary tools for the build, or you may need to re-visit the setup of your
-system due to missing software packages.</p>
-
-<p><strong>NOTE:</strong> The <code>configure</code> script file does not have execute permissions and
-will need to be explicitly run with <code>bash</code>, see the source guidelines.</p>
-
-<hr />
-
-<p><a name="setup"></a></p>
-
-<h3>System Setup</h3>
-
-<p>Before even attempting to use a system to build the OpenJDK there are some very
-basic system setups needed. For all systems:</p>
-
-<ul>
-<li><p>Be sure the GNU make utility is version 3.81 (4.0 on windows) or newer, e.g.
-run "<code>make -version</code>"</p>
-
-<p><a name="bootjdk"></a></p></li>
-<li><p>Install a Bootstrap JDK. All OpenJDK builds require access to a previously
-released JDK called the <em>bootstrap JDK</em> or <em>boot JDK.</em> The general rule is
-that the bootstrap JDK must be an instance of the previous major release of
-the JDK. In addition, there may be a requirement to use a release at or
-beyond a particular update level.</p>
-
-<p><strong><em>Building JDK 9 requires JDK 8. JDK 9 developers should not use JDK 9 as
-the boot JDK, to ensure that JDK 9 dependencies are not introduced into the
-parts of the system that are built with JDK 8.</em></strong></p>
-
-<p>The JDK 8 binaries can be downloaded from Oracle's <a href="http://www.oracle.com/technetwork/java/javase/downloads/index.html">JDK 8 download
-site</a>.
-For build performance reasons it is very important that this bootstrap JDK
-be made available on the local disk of the machine doing the build. You
-should add its <code>bin</code> directory to the <code>PATH</code> environment variable. If
-<code>configure</code> has any issues finding this JDK, you may need to use the
-<code>configure</code> option <code>--with-boot-jdk</code>.</p></li>
-<li><p>Ensure that GNU make, the Bootstrap JDK, and the compilers are all in your
-PATH environment variable.</p></li>
-</ul>
-
-<p>And for specific systems:</p>
-
-<ul>
-<li><p><strong>Linux</strong></p>
-
-<p>Install all the software development packages needed including
-<a href="#alsa">alsa</a>, <a href="#freetype">freetype</a>, <a href="#cups">cups</a>, and
-<a href="#xrender">xrender</a>. See <a href="#SDBE">specific system packages</a>.</p></li>
-<li><p><strong>Solaris</strong></p>
-
-<p>Install all the software development packages needed including <a href="#studio">Studio
-Compilers</a>, <a href="#freetype">freetype</a>, <a href="#cups">cups</a>, and
-<a href="#xrender">xrender</a>. See <a href="#SDBE">specific system packages</a>.</p></li>
-<li><p><strong>Windows</strong></p>
-
-<ul>
-<li>Install one of <a href="#cygwin">CYGWIN</a> or <a href="#msys">MinGW/MSYS</a></li>
-<li>Install <a href="#vs2013">Visual Studio 2013</a></li>
-</ul></li>
-<li><p><strong>Mac OS X</strong></p>
-
-<p>Install <a href="https://developer.apple.com/xcode/">XCode 6.3</a></p></li>
-</ul>
-
-<p><a name="linux"></a></p>
-
-<h4>Linux</h4>
-
-<p>With Linux, try and favor the system packages over building your own or getting
-packages from other areas. Most Linux builds should be possible with the
-system's available packages.</p>
-
-<p>Note that some Linux systems have a habit of pre-populating your environment
-variables for you, for example <code>JAVA_HOME</code> might get pre-defined for you to
-refer to the JDK installed on your Linux system. You will need to unset
-<code>JAVA_HOME</code>. It's a good idea to run <code>env</code> and verify the environment variables
-you are getting from the default system settings make sense for building the
-OpenJDK.</p>

-<h5>Studio Compilers</h5>
-
-<p>At a minimum, the <a href="http://www.oracle.com/
-technetwork/server-storage/solarisstudio/downloads/index.htm">Studio 12 Update 4 Compilers</a> (containing
-version 5.13 of the C and C++ compilers) is required, including specific
-patches.</p>
-
-<p>The Solaris Studio installation should contain at least these packages:</p>
-

-
-<p>Place the <code>bin</code> directory in <code>PATH</code>.</p>

-
-<h4>Windows</h4>
-
-<h5>Windows Unix Toolkit</h5>
-
-<p>Building on Windows requires a Unix-like environment, notably a Unix-like
-shell. There are several such environments available of which
-<a href="http://www.cygwin.com/">Cygwin</a> and
-<a href="http://www.mingw.org/wiki/MSYS">MinGW/MSYS</a> are currently supported for the
-OpenJDK build. One of the differences of these systems from standard Windows
-tools is the way they handle Windows path names, particularly path names which
-contain spaces, backslashes as path separators and possibly drive letters.
-Depending on the use case and the specifics of each environment these path
-problems can be solved by a combination of quoting whole paths, translating
-backslashes to forward slashes, escaping backslashes with additional
-backslashes and translating the path names to their <a href="http://en.wikipedia.org/wiki/8.3_filename">"8.3"
-version</a>.</p>
-
-<p><a name="cygwin"></a></p>
-
-<h6>CYGWIN</h6>
-
-<p>CYGWIN is an open source, Linux-like environment which tries to emulate a
-complete POSIX layer on Windows. It tries to be smart about path names and can
-usually handle all kinds of paths if they are correctly quoted or escaped
-although internally it maps drive letters <code><drive>:</code> to a virtual directory
-<code>/cygdrive/<drive></code>.</p>
-
-<p>You can always use the <code>cygpath</code> utility to map pathnames with spaces or the
-backslash character into the <code>C:/</code> style of pathname (called 'mixed'), e.g.
-<code>cygpath -s -m "<path>"</code>.</p>
-
-<p>Note that the use of CYGWIN creates a unique problem with regards to setting
-<a href="#path"><code>PATH</code></a>. Normally on Windows the <code>PATH</code> variable contains directories
-separated with the ";" character (Solaris and Linux use ":"). With CYGWIN, it
-uses ":", but that means that paths like "C:/path" cannot be placed in the
-CYGWIN version of <code>PATH</code> and instead CYGWIN uses something like
-<code>/cygdrive/c/path</code> which CYGWIN understands, but only CYGWIN understands.</p>
-
-<p>The OpenJDK build requires CYGWIN version 1.7.16 or newer. Information about
-CYGWIN can be obtained from the CYGWIN website at
-<a href="http://www.cygwin.com">www.cygwin.com</a>.</p>
-
-<p>By default CYGWIN doesn't install all the tools required for building the
-OpenJDK. Along with the default installation, you need to install the following
-tools.</p>
-
-<blockquote>

-<p><a name="msys"></a></p>
-
-<h6>MinGW/MSYS</h6>
-
-<p>MinGW ("Minimalist GNU for Windows") is a collection of free Windows specific
-header files and import libraries combined with GNU toolsets that allow one to
-produce native Windows programs that do not rely on any 3rd-party C runtime
-DLLs. MSYS is a supplement to MinGW which allows building applications and
-programs which rely on traditional UNIX tools to be present. Among others this
-includes tools like <code>bash</code> and <code>make</code>. See <a href="http://www.mingw.org/
-wiki/MSYS">MinGW/MSYS</a> for more information.</p>
-
-<p>Like Cygwin, MinGW/MSYS can handle different types of path formats. They are
-internally converted to paths with forward slashes and drive letters
-<code><drive>:</code> replaced by a virtual directory <code>/<drive></code>. Additionally, MSYS
-automatically detects binaries compiled for the MSYS environment and feeds them
-with the internal, Unix-style path names. If native Windows applications are
-called from within MSYS programs their path arguments are automatically
-converted back to Windows style path names with drive letters and backslashes
-as path separators. This may cause problems for Windows applications which use
-forward slashes as parameter separator (e.g. <code>cl /nologo /I</code>) because MSYS may
-wrongly <a href="http://mingw.org/wiki/
-Posix_path_conversion">replace such parameters by drive letters</a>.</p>
-
-<p>In addition to the tools which will be installed by default, you have to
-manually install the <code>msys-zip</code> and <code>msys-unzip</code> packages. This can be easily
-done with the MinGW command line installer:</p>
-
-<pre><code> mingw-get.exe install msys-zip
- mingw-get.exe install msys-unzip
-</code></pre>
-
-<p><a name="vs2013"></a></p>
-
-<h5>Visual Studio 2013 Compilers</h5>
-
-<p>The 32-bit and 64-bit OpenJDK Windows build requires Microsoft Visual Studio
-C++ 2013 (VS2013) Professional Edition or Express compiler. The compiler and
-other tools are expected to reside in the location defined by the variable
-<code>VS120COMNTOOLS</code> which is set by the Microsoft Visual Studio installer.</p>
-
-<p>Only the C++ part of VS2013 is needed. Try to let the installation go to the
-default install directory. Always reboot your system after installing VS2013.
-The system environment variable VS120COMNTOOLS should be set in your
-environment.</p>
-
-<p>Make sure that TMP and TEMP are also set in the environment and refer to
-Windows paths that exist, like <code>C:\temp</code>, not <code>/tmp</code>, not <code>/cygdrive/c/temp</code>,
-and not <code>C:/temp</code>. <code>C:\temp</code> is just an example, it is assumed that this area
-is private to the user, so by default after installs you should see a unique
-user path in these variables.</p>

-<p><a name="macosx"></a></p>
-
-<h4>Mac OS X</h4>
-
-<p>Make sure you get the right XCode version.</p>
-
-<hr />
-
-<p><a name="configure"></a></p>
-
-<h3>Configure</h3>
-
-<p>The basic invocation of the <code>configure</code> script looks like:</p>
-
-<blockquote>
- <p><strong><code>bash ./configure [options]</code></strong></p>
-</blockquote>
-
-<p>This will create an output directory containing the "configuration" and setup
-an area for the build result. This directory typically looks like:</p>
-
-<blockquote>
- <p><strong><code>build/linux-x64-normal-server-release</code></strong></p>
-</blockquote>
-
-<p><code>configure</code> will try to figure out what system you are running on and where all
-necessary build components are. If you have all prerequisites for building
-installed, it should find everything. If it fails to detect any component
-automatically, it will exit and inform you about the problem. When this
-happens, read more below in <a href="#configureoptions">the <code>configure</code> options</a>.</p>
-
-<p>Some examples:</p>
-
-<blockquote>
- <p><strong>Windows 32bit build with freetype specified:</strong> <br />
- <code>bash ./configure --with-freetype=/cygdrive/c/freetype-i586 --with-target-
-bits=32</code></p>
-
-<p><strong>Debug 64bit Build:</strong> <br />
- <code>bash ./configure --enable-debug --with-target-bits=64</code></p>
-</blockquote>
-
-<p><a name="configureoptions"></a></p>
-
-<h4>Configure Options</h4>
-
-<p>Complete details on all the OpenJDK <code>configure</code> options can be seen with:</p>
-
-<blockquote>
- <p><strong><code>bash ./configure --help=short</code></strong></p>
-</blockquote>
-
-<p>Use <code>-help</code> to see all the <code>configure</code> options available. You can generate any
-number of different configurations, e.g. debug, release, 32, 64, etc.</p>
-
-<p>Some of the more commonly used <code>configure</code> options are:</p>
-
-<blockquote>
- <p><strong><code>--enable-debug</code></strong> <br />
- set the debug level to fastdebug (this is a shorthand for <code>--with-debug-
- level=fastdebug</code>)</p>

-<p><a name="faq"></a></p>
-
-<h3>FAQ</h3>
-
-<p><strong>Q:</strong> The <code>generated-configure.sh</code> file looks horrible! How are you going to
-edit it? <br />
-<strong>A:</strong> The <code>generated-configure.sh</code> file is generated (think "compiled") by the
-autoconf tools. The source code is in <code>configure.ac</code> and various .m4 files in
-common/autoconf, which are much more readable.</p>
-
-<p><strong>Q:</strong> Why is the <code>generated-configure.sh</code> file checked in, if it is
-generated? <br />
-<strong>A:</strong> If it was not generated, every user would need to have the autoconf
-tools installed, and re-generate the <code>configure</code> file as the first step. Our
-goal is to minimize the work needed to be done by the user to start building
-OpenJDK, and to minimize the number of external dependencies required.</p>
-
-<p><strong>Q:</strong> Do you require a specific version of autoconf for regenerating
-<code>generated-configure.sh</code>? <br />
-<strong>A:</strong> Yes, version 2.69 is required and should be easy enough to aquire on all
-supported operating systems. The reason for this is to avoid large spurious
-changes in <code>generated-configure.sh</code>.</p>
-
-<p><strong>Q:</strong> How do you regenerate <code>generated-configure.sh</code> after making changes to
-the input files? <br />
-<strong>A:</strong> Regnerating <code>generated-configure.sh</code> should always be done using the
-script <code>common/autoconf/autogen.sh</code> to ensure that the correct files get
-updated. This script should also be run after mercurial tries to merge
-<code>generated-configure.sh</code> as a merge of the generated file is not guaranteed to
-be correct.</p>
-
-<p><strong>Q:</strong> What are the files in <code>common/makefiles/support/*</code> for? They look like
-gibberish. <br />
-<strong>A:</strong> They are a somewhat ugly hack to compensate for command line length
-limitations on certain platforms (Windows, Solaris). Due to a combination of
-limitations in make and the shell, command lines containing too many files will
-not work properly. These helper files are part of an elaborate hack that will
-compress the command line in the makefile and then uncompress it safely. We're
-not proud of it, but it does fix the problem. If you have any better
-suggestions, we're all ears! :-)</p>
-
-<p><strong>Q:</strong> I want to see the output of the commands that make runs, like in the old
-build. How do I do that? <br />
-<strong>A:</strong> You specify the <code>LOG</code> variable to make. There are several log levels:</p>
-
-<ul>
-<li><strong><code>warn</code></strong> -- Default and very quiet.</li>
-<li><strong><code>info</code></strong> -- Shows more progress information than warn.</li>
-<li><strong><code>debug</code></strong> -- Echos all command lines and prints all macro calls for
-compilation definitions.</li>
-<li><strong><code>trace</code></strong> -- Echos all $(shell) command lines as well.</li>
-</ul>
-
-<p><strong>Q:</strong> When do I have to re-run <code>configure</code>? <br />
-<strong>A:</strong> Normally you will run <code>configure</code> only once for creating a
-configuration. You need to re-run configuration only if you want to change any
-configuration options, or if you pull down changes to the <code>configure</code> script.</p>
-
-<p><strong>Q:</strong> I have added a new source file. Do I need to modify the makefiles? <br />
-<strong>A:</strong> Normally, no. If you want to create e.g. a new native library, you will
-need to modify the makefiles. But for normal file additions or removals, no
-changes are needed. There are certan exceptions for some native libraries where
-the source files are spread over many directories which also contain sources
-for other libraries. In these cases it was simply easier to create include
-lists rather than excludes.</p>
-
-<p><strong>Q:</strong> When I run <code>configure --help</code>, I see many strange options, like
-<code>--dvidir</code>. What is this? <br />
-<strong>A:</strong> Configure provides a slew of options by default, to all projects that
-use autoconf. Most of them are not used in OpenJDK, so you can safely ignore
-them. To list only OpenJDK specific features, use <code>configure --help=short</code>
-instead.</p>
-
-<p><strong>Q:</strong> <code>configure</code> provides OpenJDK-specific features such as <code>--with-
-builddeps-server</code> that are not described in this document. What about those? <br />
-<strong>A:</strong> Try them out if you like! But be aware that most of these are
-experimental features. Many of them don't do anything at all at the moment; the
-option is just a placeholder. Others depend on pieces of code or infrastructure
-that is currently not ready for prime time.</p>
-
-<p><strong>Q:</strong> How will you make sure you don't break anything? <br />
-<strong>A:</strong> We have a script that compares the result of the new build system with
-the result of the old. For most part, we aim for (and achieve) byte-by-byte
-identical output. There are however technical issues with e.g. native binaries,
-which might differ in a byte-by-byte comparison, even when building twice with
-the old build system. For these, we compare relevant aspects (e.g. the symbol
-table and file size). Note that we still don't have 100% equivalence, but we're
-close.</p>
-
-<p><strong>Q:</strong> I noticed this thing X in the build that looks very broken by design.
-Why don't you fix it? <br />
-<strong>A:</strong> Our goal is to produce a build output that is as close as technically
-possible to the old build output. If things were weird in the old build, they
-will be weird in the new build. Often, things were weird before due to
-obscurity, but in the new build system the weird stuff comes up to the surface.
-The plan is to attack these things at a later stage, after the new build system
-is established.</p>
-
-<p><strong>Q:</strong> The code in the new build system is not that well-structured. Will you
-fix this? <br />
-<strong>A:</strong> Yes! The new build system has grown bit by bit as we converted the old
-system. When all of the old build system is converted, we can take a step back
-and clean up the structure of the new build system. Some of this we plan to do
-before replacing the old build system and some will need to wait until after.</p>
-
-<p><strong>Q:</strong> Is anything able to use the results of the new build's default make
-target? <br />
-<strong>A:</strong> Yes, this is the minimal (or roughly minimal) set of compiled output
-needed for a developer to actually execute the newly built JDK. The idea is
-that in an incremental development fashion, when doing a normal make, you
-should only spend time recompiling what's changed (making it purely
-incremental) and only do the work that's needed to actually run and test your
-code. The packaging stuff that is part of the <code>images</code> target is not needed for
-a normal developer who wants to test his new code. Even if it's quite fast,
-it's still unnecessary. We're targeting sub-second incremental rebuilds! ;-)
-(Or, well, at least single-digit seconds...)</p>
-
-<p><strong>Q:</strong> I usually set a specific environment variable when building, but I can't
-find the equivalent in the new build. What should I do? <br />
-<strong>A:</strong> It might very well be that we have neglected to add support for an
-option that was actually used from outside the build system. Email us and we
-will add support for it!</p>

-<h3>Build Performance Tips</h3>
-
-<p>Building OpenJDK requires a lot of horsepower. Some of the build tools can be
-adjusted to utilize more or less of resources such as parallel threads and
-memory. The <code>configure</code> script analyzes your system and selects reasonable
-values for such options based on your hardware. If you encounter resource
-problems, such as out of memory conditions, you can modify the detected values
-with:</p>
-
-<ul>
-<li><strong><code>--with-num-cores</code></strong> -- number of cores in the build system, e.g.
-<code>--with-num-cores=8</code></li>
-<li><strong><code>--with-memory-size</code></strong> -- memory (in MB) available in the build system,
-e.g. <code>--with-memory-size=1024</code></li>
-</ul>
-
-<p>It might also be necessary to specify the JVM arguments passed to the Bootstrap
-JDK, using e.g. <code>--with-boot-jdk-jvmargs="-Xmx8G -enableassertions"</code>. Doing
-this will override the default JVM arguments passed to the Bootstrap JDK.</p>
-
-<p>One of the top goals of the new build system is to improve the build
-performance and decrease the time needed to build. This will soon also apply to
-the java compilation when the Smart Javac wrapper is fully supported.</p>
-
-<p>At the end of a successful execution of <code>configure</code>, you will get a performance
-summary, indicating how well the build will perform. Here you will also get
-performance hints. If you want to build fast, pay attention to those!</p>
-
-<h4>Building with ccache</h4>
-
-<p>The OpenJDK build supports building with ccache when using gcc or clang. Using
-ccache can radically speed up compilation of native code if you often rebuild
-the same sources. Your milage may vary however so we recommend evaluating it
-for yourself. To enable it, make sure it's on the path and configure with
-<code>--enable-ccache</code>.</p>
-
-<h4>Building on local disk</h4>
-
-<p>If you are using network shares, e.g. via NFS, for your source code, make sure
-the build directory is situated on local disk. The performance penalty is
-extremely high for building on a network share, close to unusable.</p>
-
-<h4>Building only one JVM</h4>
-
-<p>The old build builds multiple JVMs on 32-bit systems (client and server; and on
-Windows kernel as well). In the new build we have changed this default to only
-build server when it's available. This improves build times for those not
-interested in multiple JVMs. To mimic the old behavior on platforms that
-support it, use <code>--with-jvm-variants=client,server</code>.</p>
-
-<h4>Selecting the number of cores to build on</h4>
-
-<p>By default, <code>configure</code> will analyze your machine and run the make process in
-parallel with as many threads as you have cores. This behavior can be
-overridden, either "permanently" (on a <code>configure</code> basis) using
-<code>--with-num-cores=N</code> or for a single build only (on a make basis), using
-<code>make JOBS=N</code>.</p>
-
-<p>If you want to make a slower build just this time, to save some CPU power for
-other processes, you can run e.g. <code>make JOBS=2</code>. This will force the makefiles
-to only run 2 parallel processes, or even <code>make JOBS=1</code> which will disable
-parallelism.</p>
-
-<p>If you want to have it the other way round, namely having slow builds default
-and override with fast if you're impatient, you should call <code>configure</code> with
-<code>--with-num-cores=2</code>, making 2 the default. If you want to run with more cores,
-run <code>make JOBS=8</code></p>
-
-<p><a name="troubleshooting"></a></p>
-
-<h3>Troubleshooting</h3>
-
-<h4>Solving build problems</h4>
-
-<p>If the build fails (and it's not due to a compilation error in a source file
-you've changed), the first thing you should do is to re-run the build with more
-verbosity. Do this by adding <code>LOG=debug</code> to your make command line.</p>
-
-<p>The build log (with both stdout and stderr intermingled, basically the same as
-you see on your console) can be found as <code>build.log</code> in your build directory.</p>
-
-<p>You can ask for help on build problems with the new build system on either the
-<a href="http://mail.openjdk.java.net/mailman/listinfo/build-dev">build-dev</a> or the
-<a href="http://mail.openjdk.java.net/mailman/listinfo/build-infra-dev">build-infra-dev</a>
-mailing lists. Please include the relevant parts of the build log.</p>
-
-<p>A build can fail for any number of reasons. Most failures are a result of
-trying to build in an environment in which all the pre-build requirements have
-not been met. The first step in troubleshooting a build failure is to recheck
-that you have satisfied all the pre-build requirements for your platform.
-Scanning the <code>configure</code> log is a good first step, making sure that what it
-found makes sense for your system. Look for strange error messages or any
-difficulties that <code>configure</code> had in finding things.</p>
-
-<p>Some of the more common problems with builds are briefly described below, with
-suggestions for remedies.</p>
-
-<ul>
-<li><p><strong>Corrupted Bundles on Windows:</strong> <br />
-Some virus scanning software has been known to corrupt the downloading of
-zip bundles. It may be necessary to disable the 'on access' or 'real time'
-virus scanning features to prevent this corruption. This type of 'real time'
-virus scanning can also slow down the build process significantly.
-Temporarily disabling the feature, or excluding the build output directory
-may be necessary to get correct and faster builds.</p></li>
-<li><p><strong>Slow Builds:</strong> <br />
-If your build machine seems to be overloaded from too many simultaneous C++
-compiles, try setting the <code>JOBS=1</code> on the <code>make</code> command line. Then try
-increasing the count slowly to an acceptable level for your system. Also:</p>
-
-<p>Creating the javadocs can be very slow, if you are running javadoc, consider
-skipping that step.</p>
-
-<p>Faster CPUs, more RAM, and a faster DISK usually helps. The VM build tends
-to be CPU intensive (many C++ compiles), and the rest of the JDK will often
-be disk intensive.</p>
-
-<p>Faster compiles are possible using a tool called
-<a href="http://ccache.samba.org/">ccache</a>.</p></li>
-<li><p><strong>File time issues:</strong> <br />
-If you see warnings that refer to file time stamps, e.g.</p>
-
-<blockquote>
- <p><em>Warning message:</em> <code>File 'xxx' has modification time in the future.</code> <br />
-<em>Warning message:</em> <code>Clock skew detected. Your build may be incomplete.</code></p>
-</blockquote>
-
-<p>These warnings can occur when the clock on the build machine is out of sync
-with the timestamps on the source files. Other errors, apparently unrelated
-but in fact caused by the clock skew, can occur along with the clock skew
-warnings. These secondary errors may tend to obscure the fact that the true
-root cause of the problem is an out-of-sync clock.</p>
-
-<p>If you see these warnings, reset the clock on the build machine, run
-"<code>gmake clobber</code>" or delete the directory containing the build output, and
-restart the build from the beginning.</p></li>
-<li><p><strong>Error message: <code>Trouble writing out table to disk</code></strong> <br />
-Increase the amount of swap space on your build machine. This could be
-caused by overloading the system and it may be necessary to use:</p>
-
-<blockquote>
- <p><code>make JOBS=1</code></p>
-</blockquote>
-
-<p>to reduce the load on the system.</p></li>
-<li><p><strong>Error Message: <code>libstdc++ not found</code>:</strong> <br />
-This is caused by a missing libstdc++.a library. This is installed as part
-of a specific package (e.g. libstdc++.so.devel.386). By default some 64-bit
-Linux versions (e.g. Fedora) only install the 64-bit version of the
-libstdc++ package. Various parts of the JDK build require a static link of
-the C++ runtime libraries to allow for maximum portability of the built
-images.</p></li>
-<li><p><strong>Linux Error Message: <code>cannot restore segment prot after reloc</code></strong> <br />
-This is probably an issue with SELinux (See <a href="http://en.wikipedia.org/wiki/SELinux">SELinux on
-Wikipedia</a>). Parts of the VM is built
-without the <code>-fPIC</code> for performance reasons.</p>
-
-<p>To completely disable SELinux:</p>
-
-<ol>
-<li><code>$ su root</code></li>
-<li><code># system-config-securitylevel</code></li>
-<li><code>In the window that appears, select the SELinux tab</code></li>
-<li><code>Disable SELinux</code></li>
-</ol>
-
-<p>Alternatively, instead of completely disabling it you could disable just
-this one check.</p>
-
-<ol>
-<li>Select System->Administration->SELinux Management</li>
-<li>In the SELinux Management Tool which appears, select "Boolean" from the
-menu on the left</li>
-<li>Expand the "Memory Protection" group</li>
-<li>Check the first item, labeled "Allow all unconfined executables to use
-libraries requiring text relocation ..."</li>
-</ol></li>
-<li><p><strong>Windows Error Messages:</strong> <br />
-<code>*** fatal error - couldn't allocate heap, ...</code> <br />
-<code>rm fails with "Directory not empty"</code> <br />
-<code>unzip fails with "cannot create ... Permission denied"</code> <br />
-<code>unzip fails with "cannot create ... Error 50"</code></p>
-
-<p>The CYGWIN software can conflict with other non-CYGWIN software. See the
-CYGWIN FAQ section on <a href="http://cygwin.com/faq/faq.using.html#faq.using.bloda">BLODA (applications that interfere with
-CYGWIN)</a>.</p></li>
-<li><p><strong>Windows Error Message: <code>spawn failed</code></strong> <br />
-Try rebooting the system, or there could be some kind of issue with the disk
-or disk partition being used. Sometimes it comes with a "Permission Denied"
-message.</p></li>

-<h2>Appendix B: GNU make</h2>
-
-<p>The Makefiles in the OpenJDK are only valid when used with the GNU version of
-the utility command <code>make</code> (usually called <code>gmake</code> on Solaris). A few notes
-about using GNU make:</p>
-
-<ul>
-<li>You need GNU make version 3.81 or newer. On Windows 4.0 or newer is
-recommended. If the GNU make utility on your systems is not of a suitable
-version, see "<a href="#buildgmake">Building GNU make</a>".</li>
-<li>Place the location of the GNU make binary in the <code>PATH</code>.</li>
-<li><strong>Solaris:</strong> Do NOT use <code>/usr/bin/make</code> on Solaris. If your Solaris system
-has the software from the Solaris Developer Companion CD installed, you
-should try and use <code>/usr/bin/gmake</code> or <code>/usr/gnu/bin/make</code>.</li>
-<li><strong>Windows:</strong> Make sure you start your build inside a bash shell.</li>
-<li><strong>Mac OS X:</strong> The XCode "command line tools" must be installed on your Mac.</li>
-</ul>
-
-<p>Information on GNU make, and access to ftp download sites, are available on the
-<a href="http://www.gnu.org/software/make/make.html">GNU make web site </a>. The latest
-source to GNU make is available at
-<a href="http://ftp.gnu.org/pub/gnu/make/">ftp.gnu.org/pub/gnu/make/</a>.</p>

-<h3>Building GNU make</h3>
-
-<p>First step is to get the GNU make 3.81 or newer source from

-JDK product. Building with the MBE will hopefully generate the most compatible
-bits that install on, and run correctly on, the most variations of the same
-base OS and hardware architecture. In some cases, these represent what is often
-called the least common denominator, but each Operating System has different
-aspects to it.</p>
-
-<p>In all cases, the Bootstrap JDK version minimum is critical, we cannot
-guarantee builds will work with older Bootstrap JDK's. Also in all cases, more
-RAM and more processors is better, the minimums listed below are simply
-recommendations.</p>
-
-<p>With Solaris and Mac OS X, the version listed below is the oldest release we
-can guarantee builds and works, and the specific version of the compilers used
-could be critical.</p>
-
-<p>With Windows the critical aspect is the Visual Studio compiler used, which due
-to it's runtime, generally dictates what Windows systems can do the builds and
-where the resulting bits can be used.</p>
-
-<p><strong>NOTE: We expect a change here off these older Windows OS releases and to a
-'less older' one, probably Windows 2008R2 X64.</strong></p>
-
-<p>With Linux, it was just a matter of picking a stable distribution that is a
-good representative for Linux in general.</p>
-
-<p>It is understood that most developers will NOT be using these specific
-versions, and in fact creating these specific versions may be difficult due to
-the age of some of this software. It is expected that developers are more often
-using the more recent releases and distributions of these operating systems.</p>
-
-<p>Compilation problems with newer or different C/C++ compilers is a common
-problem. Similarly, compilation problems related to changes to the
-<code>/usr/include</code> or system header files is also a common problem with older,
-newer, or unreleased OS versions. Please report these types of problems as bugs
-so that they can be dealt with accordingly.</p>

-# OpenJDK Build README
-
-*****
-
-<a name="introduction"></a>
-## Introduction
-
-This README file contains build instructions for the
-[OpenJDK](http://openjdk.java.net). Building the source code for the OpenJDK
-requires a certain degree of technical expertise.
-
-### !!!!!!!!!!!!!!! THIS IS A MAJOR RE-WRITE of this document. !!!!!!!!!!!!!
-
-Some Headlines:
-
- * The build is now a "`configure && make`" style build
- * Any GNU make 3.81 or newer should work, except on Windows where 4.0 or newer
- is recommended.
- * The build should scale, i.e. more processors should cause the build to be
- done in less wall-clock time
- * Nested or recursive make invocations have been significantly reduced,
- as has the total fork/exec or spawning of sub processes during the build
- * Windows MKS usage is no longer supported
- * Windows Visual Studio `vsvars*.bat` and `vcvars*.bat` files are run
- automatically
- * Ant is no longer used when building the OpenJDK
- * Use of ALT_* environment variables for configuring the build is no longer
- supported
-

-<a name="hg"></a>
-## Use of Mercurial
-
-The OpenJDK sources are maintained with the revision control system
-[Mercurial](http://mercurial.selenic.com/wiki/Mercurial). If you are new to
-Mercurial, please see the [Beginner Guides](http://mercurial.selenic.com/wiki/
-BeginnersGuides) or refer to the [Mercurial Book](http://hgbook.red-bean.com/).
-The first few chapters of the book provide an excellent overview of Mercurial,
-what it is and how it works.
-
-For using Mercurial with the OpenJDK refer to the [Developer Guide: Installing
-and Configuring Mercurial](http://openjdk.java.net/guide/
-repositories.html#installConfig) section for more information.
-
-<a name="get_source"></a>
-### Getting the Source
-
-To get the entire set of OpenJDK Mercurial repositories use the script
-`get_source.sh` located in the root repository:
-
- hg clone http://hg.openjdk.java.net/jdk9/jdk9 YourOpenJDK
- cd YourOpenJDK
- bash ./get_source.sh
-
-Once you have all the repositories, keep in mind that each repository is its
-own independent repository. You can also re-run `./get_source.sh` anytime to
-pull over all the latest changesets in all the repositories. This set of
-nested repositories has been given the term "forest" and there are various
-ways to apply the same `hg` command to each of the repositories. For
-example, the script `make/scripts/hgforest.sh` can be used to repeat the
-same `hg` command on every repository, e.g.
-
- cd YourOpenJDK
- bash ./make/scripts/hgforest.sh status
-
-<a name="repositories"></a>
-### Repositories
-
-The set of repositories and what they contain:
-
- * **. (root)** contains common configure and makefile logic
- * **hotspot** contains source code and make files for building the OpenJDK
- Hotspot Virtual Machine
- * **langtools** contains source code for the OpenJDK javac and language tools
- * **jdk** contains source code and make files for building the OpenJDK runtime
- libraries and misc files
- * **jaxp** contains source code for the OpenJDK JAXP functionality
- * **jaxws** contains source code for the OpenJDK JAX-WS functionality
- * **corba** contains source code for the OpenJDK Corba functionality
- * **nashorn** contains source code for the OpenJDK JavaScript implementation
-
-### Repository Source Guidelines
-
-There are some very basic guidelines:
-
- * Use of whitespace in source files (.java, .c, .h, .cpp, and .hpp files) is
- restricted. No TABs, no trailing whitespace on lines, and files should not
- terminate in more than one blank line.
- * Files with execute permissions should not be added to the source
- repositories.
- * All generated files need to be kept isolated from the files maintained or
- managed by the source control system. The standard area for generated files
- is the top level `build/` directory.
- * The default build process should be to build the product and nothing else,
- in one form, e.g. a product (optimized), debug (non-optimized, -g plus
- assert logic), or fastdebug (optimized, -g plus assert logic).
- * The `.hgignore` file in each repository must exist and should include
- `^build/`, `^dist/` and optionally any `nbproject/private` directories. **It
- should NEVER** include anything in the `src/` or `test/` or any managed
- directory area of a repository.
- * Directory names and file names should never contain blanks or non-printing
- characters.
- * Generated source or binary files should NEVER be added to the repository
- (that includes `javah` output). There are some exceptions to this rule, in
- particular with some of the generated configure scripts.
- * Files not needed for typical building or testing of the repository should
- not be added to the repository.

-## Building
-
-The very first step in building the OpenJDK is making sure the system itself
-has everything it needs to do OpenJDK builds. Once a system is setup, it
-generally doesn't need to be done again.
-
-Building the OpenJDK is now done with running a `configure` script which will
-try and find and verify you have everything you need, followed by running
-`make`, e.g.
-
-> **`bash ./configure`**
-> **`make all`**
-
-Where possible the `configure` script will attempt to located the various
-components in the default locations or via component specific variable
-settings. When the normal defaults fail or components cannot be found,
-additional `configure` options may be necessary to help `configure` find the
-necessary tools for the build, or you may need to re-visit the setup of your
-system due to missing software packages.
-
-**NOTE:** The `configure` script file does not have execute permissions and
-will need to be explicitly run with `bash`, see the source guidelines.
-
-*****
-
-<a name="setup"></a>
-### System Setup
-
-Before even attempting to use a system to build the OpenJDK there are some very
-basic system setups needed. For all systems:
-
- * Be sure the GNU make utility is version 3.81 (4.0 on windows) or newer, e.g.
- run "`make -version`"
-
- <a name="bootjdk"></a>
- * Install a Bootstrap JDK. All OpenJDK builds require access to a previously
- released JDK called the _bootstrap JDK_ or _boot JDK._ The general rule is
- that the bootstrap JDK must be an instance of the previous major release of
- the JDK. In addition, there may be a requirement to use a release at or
- beyond a particular update level.
-
- **_Building JDK 9 requires JDK 8. JDK 9 developers should not use JDK 9 as
- the boot JDK, to ensure that JDK 9 dependencies are not introduced into the
- parts of the system that are built with JDK 8._**
-
- The JDK 8 binaries can be downloaded from Oracle's [JDK 8 download
- site](http://www.oracle.com/technetwork/java/javase/downloads/index.html).
- For build performance reasons it is very important that this bootstrap JDK
- be made available on the local disk of the machine doing the build. You
- should add its `bin` directory to the `PATH` environment variable. If
- `configure` has any issues finding this JDK, you may need to use the
- `configure` option `--with-boot-jdk`.
-
- * Ensure that GNU make, the Bootstrap JDK, and the compilers are all in your
- PATH environment variable.
-
-And for specific systems:
-
- * **Linux**
-
- Install all the software development packages needed including
- [alsa](#alsa), [freetype](#freetype), [cups](#cups), and
- [xrender](#xrender). See [specific system packages](#SDBE).
-
- * **Solaris**
-
- Install all the software development packages needed including [Studio
- Compilers](#studio), [freetype](#freetype), [cups](#cups), and
- [xrender](#xrender). See [specific system packages](#SDBE).
-
- * **Windows**
-
- * Install one of [CYGWIN](#cygwin) or [MinGW/MSYS](#msys)
- * Install [Visual Studio 2013](#vs2013)
-
- * **Mac OS X**
-
- Install [XCode 6.3](https://developer.apple.com/xcode/)
-
-<a name="linux"></a>
-#### Linux
-
-With Linux, try and favor the system packages over building your own or getting
-packages from other areas. Most Linux builds should be possible with the
-system's available packages.
-
-Note that some Linux systems have a habit of pre-populating your environment
-variables for you, for example `JAVA_HOME` might get pre-defined for you to
-refer to the JDK installed on your Linux system. You will need to unset
-`JAVA_HOME`. It's a good idea to run `env` and verify the environment variables
-you are getting from the default system settings make sense for building the
-OpenJDK.
-
-<a name="solaris"></a>
-#### Solaris
-
-<a name="studio"></a>
-##### Studio Compilers
-
-At a minimum, the [Studio 12 Update 4 Compilers](http://www.oracle.com/
-technetwork/server-storage/solarisstudio/downloads/index.htm) (containing
-version 5.13 of the C and C++ compilers) is required, including specific
-patches.
-
-The Solaris Studio installation should contain at least these packages:
-
-> <table border="1">
- <thead>
- <tr>
- <td>**Package**</td>
- <td>**Version**</td>
- </tr>
- </thead>
- <tbody>
- <tr>

- </tr>
- </tbody>
- </table>
-
-In particular backend 12.4-1.0.6.0 contains a critical patch for the sparc
-version.
-
-Place the `bin` directory in `PATH`.
-
-The Oracle Solaris Studio Express compilers at: [Oracle Solaris Studio Express
-Download site](http://www.oracle.com/technetwork/server-storage/solarisstudio/
-downloads/index-jsp-142582.html) are also an option, although these compilers
-have not been extensively used yet.
-
-<a name="windows"></a>
-#### Windows
-
-##### Windows Unix Toolkit
-
-Building on Windows requires a Unix-like environment, notably a Unix-like
-shell. There are several such environments available of which
-[Cygwin](http://www.cygwin.com/) and
-[MinGW/MSYS](http://www.mingw.org/wiki/MSYS) are currently supported for the
-OpenJDK build. One of the differences of these systems from standard Windows
-tools is the way they handle Windows path names, particularly path names which
-contain spaces, backslashes as path separators and possibly drive letters.
-Depending on the use case and the specifics of each environment these path
-problems can be solved by a combination of quoting whole paths, translating
-backslashes to forward slashes, escaping backslashes with additional
-backslashes and translating the path names to their ["8.3"
-version](http://en.wikipedia.org/wiki/8.3_filename).
-
-<a name="cygwin"></a>
-###### CYGWIN
-
-CYGWIN is an open source, Linux-like environment which tries to emulate a
-complete POSIX layer on Windows. It tries to be smart about path names and can
-usually handle all kinds of paths if they are correctly quoted or escaped
-although internally it maps drive letters `<drive>:` to a virtual directory
-`/cygdrive/<drive>`.
-
-You can always use the `cygpath` utility to map pathnames with spaces or the
-backslash character into the `C:/` style of pathname (called 'mixed'), e.g.
-`cygpath -s -m "<path>"`.
-
-Note that the use of CYGWIN creates a unique problem with regards to setting
-[`PATH`](#path). Normally on Windows the `PATH` variable contains directories
-separated with the ";" character (Solaris and Linux use ":"). With CYGWIN, it
-uses ":", but that means that paths like "C:/path" cannot be placed in the
-CYGWIN version of `PATH` and instead CYGWIN uses something like
-`/cygdrive/c/path` which CYGWIN understands, but only CYGWIN understands.
-
-The OpenJDK build requires CYGWIN version 1.7.16 or newer. Information about
-CYGWIN can be obtained from the CYGWIN website at
-[www.cygwin.com](http://www.cygwin.com).
-
-By default CYGWIN doesn't install all the tools required for building the
-OpenJDK. Along with the default installation, you need to install the following
-tools.

-
-Note that the CYGWIN software can conflict with other non-CYGWIN software on
-your Windows system. CYGWIN provides a [FAQ](http://cygwin.com/faq/
-faq.using.html) for known issues and problems, of particular interest is the
-section on [BLODA (applications that interfere with
-CYGWIN)](http://cygwin.com/faq/faq.using.html#faq.using.bloda).
-
-<a name="msys"></a>
-###### MinGW/MSYS
-
-MinGW ("Minimalist GNU for Windows") is a collection of free Windows specific
-header files and import libraries combined with GNU toolsets that allow one to
-produce native Windows programs that do not rely on any 3rd-party C runtime
-DLLs. MSYS is a supplement to MinGW which allows building applications and
-programs which rely on traditional UNIX tools to be present. Among others this
-includes tools like `bash` and `make`. See [MinGW/MSYS](http://www.mingw.org/
-wiki/MSYS) for more information.
-
-Like Cygwin, MinGW/MSYS can handle different types of path formats. They are
-internally converted to paths with forward slashes and drive letters
-`<drive>:` replaced by a virtual directory `/<drive>`. Additionally, MSYS
-automatically detects binaries compiled for the MSYS environment and feeds them
-with the internal, Unix-style path names. If native Windows applications are
-called from within MSYS programs their path arguments are automatically
-converted back to Windows style path names with drive letters and backslashes
-as path separators. This may cause problems for Windows applications which use
-forward slashes as parameter separator (e.g. `cl /nologo /I`) because MSYS may
-wrongly [replace such parameters by drive letters](http://mingw.org/wiki/
-Posix_path_conversion).
-
-In addition to the tools which will be installed by default, you have to
-manually install the `msys-zip` and `msys-unzip` packages. This can be easily
-done with the MinGW command line installer:
-
- mingw-get.exe install msys-zip
- mingw-get.exe install msys-unzip

-##### Visual Studio 2013 Compilers
-
-The 32-bit and 64-bit OpenJDK Windows build requires Microsoft Visual Studio
-C++ 2013 (VS2013) Professional Edition or Express compiler. The compiler and
-other tools are expected to reside in the location defined by the variable
-`VS120COMNTOOLS` which is set by the Microsoft Visual Studio installer.
-
-Only the C++ part of VS2013 is needed. Try to let the installation go to the
-default install directory. Always reboot your system after installing VS2013.
-The system environment variable VS120COMNTOOLS should be set in your
-environment.
-
-Make sure that TMP and TEMP are also set in the environment and refer to
-Windows paths that exist, like `C:\temp`, not `/tmp`, not `/cygdrive/c/temp`,
-and not `C:/temp`. `C:\temp` is just an example, it is assumed that this area
-is private to the user, so by default after installs you should see a unique
-user path in these variables.

-
-<a name="configure"></a>
-### Configure
-
-The basic invocation of the `configure` script looks like:
-
-> **`bash ./configure [options]`**
-
-This will create an output directory containing the "configuration" and setup
-an area for the build result. This directory typically looks like:
-
-> **`build/linux-x64-normal-server-release`**
-
-`configure` will try to figure out what system you are running on and where all
-necessary build components are. If you have all prerequisites for building
-installed, it should find everything. If it fails to detect any component
-automatically, it will exit and inform you about the problem. When this
-happens, read more below in [the `configure` options](#configureoptions).
-
-Some examples:
-
-> **Windows 32bit build with freetype specified:**
-> `bash ./configure --with-freetype=/cygdrive/c/freetype-i586 --with-target-
-bits=32`
-
-> **Debug 64bit Build:**
-> `bash ./configure --enable-debug --with-target-bits=64`
-
-<a name="configureoptions"></a>
-#### Configure Options
-
-Complete details on all the OpenJDK `configure` options can be seen with:
-
-> **`bash ./configure --help=short`**
-
-Use `-help` to see all the `configure` options available. You can generate any
-number of different configurations, e.g. debug, release, 32, 64, etc.
-
-Some of the more commonly used `configure` options are:
-
-> **`--enable-debug`**
-> set the debug level to fastdebug (this is a shorthand for `--with-debug-
- level=fastdebug`)
-
-<a name="alsa"></a>
-> **`--with-alsa=`**_path_
-> select the location of the Advanced Linux Sound Architecture (ALSA)
-
-> Version 0.9.1 or newer of the ALSA files are required for building the
- OpenJDK on Linux. These Linux files are usually available from an "alsa" of
- "libasound" development package, and it's highly recommended that you try
- and use the package provided by the particular version of Linux that you are
- using.
-
-> **`--with-boot-jdk=`**_path_
-> select the [Bootstrap JDK](#bootjdk)
-
-> **`--with-boot-jdk-jvmargs=`**"_args_"
-> provide the JVM options to be used to run the [Bootstrap JDK](#bootjdk)
-
-> **`--with-cacerts=`**_path_
-> select the path to the cacerts file.
-
-> See [Certificate Authority on Wikipedia](http://en.wikipedia.org/wiki/
- Certificate_Authority) for a better understanding of the Certificate
- Authority (CA). A certificates file named "cacerts" represents a system-wide
- keystore with CA certificates. In JDK and JRE binary bundles, the "cacerts"
- file contains root CA certificates from several public CAs (e.g., VeriSign,
- Thawte, and Baltimore). The source contain a cacerts file without CA root
- certificates. Formal JDK builders will need to secure permission from each
- public CA and include the certificates into their own custom cacerts file.
- Failure to provide a populated cacerts file will result in verification
- errors of a certificate chain during runtime. By default an empty cacerts
- file is provided and that should be fine for most JDK developers.
-
-<a name="cups"></a>
-> **`--with-cups=`**_path_
-> select the CUPS install location
-
-> The Common UNIX Printing System (CUPS) Headers are required for building the
- OpenJDK on Solaris and Linux. The Solaris header files can be obtained by
- installing the package **print/cups**.
-
-> The CUPS header files can always be downloaded from
- [www.cups.org](http://www.cups.org).
-
-> **`--with-cups-include=`**_path_
-> select the CUPS include directory location
-
-> **`--with-debug-level=`**_level_
-> select the debug information level of release, fastdebug, or slowdebug
-
-> **`--with-dev-kit=`**_path_
-> select location of the compiler install or developer install location
-
-<a name="freetype"></a>
-> **`--with-freetype=`**_path_
-> select the freetype files to use.
-
-> Expecting the freetype libraries under `lib/` and the headers under
- `include/`.
-
-> Version 2.3 or newer of FreeType is required. On Unix systems required files
- can be available as part of your distribution (while you still may need to
- upgrade them). Note that you need development version of package that
- includes both the FreeType library and header files.
-
-> You can always download latest FreeType version from the [FreeType
- website](http://www.freetype.org). Building the freetype 2 libraries from
- scratch is also possible, however on Windows refer to the [Windows FreeType
- DLL build instructions](http://freetype.freedesktop.org/wiki/FreeType_DLL).
-
-> Note that by default FreeType is built with byte code hinting support
- disabled due to licensing restrictions. In this case, text appearance and
- metrics are expected to differ from Sun's official JDK build. See the
- [SourceForge FreeType2 Home Page](http://freetype.sourceforge.net/freetype2)
- for more information.
-
-> **`--with-import-hotspot=`**_path_
-> select the location to find hotspot binaries from a previous build to avoid
- building hotspot
-
-> **`--with-target-bits=`**_arg_
-> select 32 or 64 bit build
-
-> **`--with-jvm-variants=`**_variants_
-> select the JVM variants to build from, comma separated list that can
- include: server, client, kernel, zero and zeroshark

- "Xrender" development package, it's recommended that you try and use the
- package provided by the particular distribution of Linux that you are using.
- The Solaris XRender header files is included with the other X11 header files
- in the package **SFWxwinc** on new enough versions of Solaris and will be
- installed in `/usr/X11/include/X11/extensions/Xrender.h` or
- `/usr/openwin/share/include/X11/extensions/Xrender.h`

-
-<a name="make"></a>
-### Make
-
-The basic invocation of the `make` utility looks like:
-
-> **`make all`**
-
-This will start the build to the output directory containing the
-"configuration" that was created by the `configure` script. Run `make help` for
-more information on the available targets.
-
-There are some of the make targets that are of general interest:
-
-> _empty_
-> build everything but no images
-
-> **`all`**
-> build everything including images
-
-> **`all-conf`**
-> build all configurations
-
-> **`images`**
-> create complete j2sdk and j2re images
-
-> **`install`**
-> install the generated images locally, typically in `/usr/local`
-
-> **`clean`**
-> remove all files generated by make, but not those generated by `configure`
-
-> **`dist-clean`**
-> remove all files generated by both and `configure` (basically killing the
- configuration)
-
-> **`help`**
-> give some help on using `make`, including some interesting make targets
-
-*****
-
-<a name="testing"></a>
-## Testing
-
-When the build is completed, you should see the generated binaries and
-associated files in the `j2sdk-image` directory in the output directory. In
-particular, the `build/*/images/j2sdk-image/bin` directory should contain
-executables for the OpenJDK tools and utilities for that configuration. The
-testing tool `jtreg` will be needed and can be found at: [the jtreg
-site](http://openjdk.java.net/jtreg/). The provided regression tests in the
-repositories can be run with the command:
-
-> **``cd test && make PRODUCT_HOME=`pwd`/../build/*/images/j2sdk-image all``**

-## Appendix A: Hints and Tips
-
-<a name="faq"></a>
-### FAQ
-
-**Q:** The `generated-configure.sh` file looks horrible! How are you going to
-edit it?
-**A:** The `generated-configure.sh` file is generated (think "compiled") by the
-autoconf tools. The source code is in `configure.ac` and various .m4 files in
-common/autoconf, which are much more readable.
-
-**Q:** Why is the `generated-configure.sh` file checked in, if it is
-generated?
-**A:** If it was not generated, every user would need to have the autoconf
-tools installed, and re-generate the `configure` file as the first step. Our
-goal is to minimize the work needed to be done by the user to start building
-OpenJDK, and to minimize the number of external dependencies required.
-
-**Q:** Do you require a specific version of autoconf for regenerating
-`generated-configure.sh`?
-**A:** Yes, version 2.69 is required and should be easy enough to aquire on all
-supported operating systems. The reason for this is to avoid large spurious
-changes in `generated-configure.sh`.
-
-**Q:** How do you regenerate `generated-configure.sh` after making changes to
-the input files?
-**A:** Regnerating `generated-configure.sh` should always be done using the
-script `common/autoconf/autogen.sh` to ensure that the correct files get
-updated. This script should also be run after mercurial tries to merge
-`generated-configure.sh` as a merge of the generated file is not guaranteed to
-be correct.
-
-**Q:** What are the files in `common/makefiles/support/*` for? They look like
-gibberish.
-**A:** They are a somewhat ugly hack to compensate for command line length
-limitations on certain platforms (Windows, Solaris). Due to a combination of
-limitations in make and the shell, command lines containing too many files will
-not work properly. These helper files are part of an elaborate hack that will
-compress the command line in the makefile and then uncompress it safely. We're
-not proud of it, but it does fix the problem. If you have any better
-suggestions, we're all ears! :-)
-
-**Q:** I want to see the output of the commands that make runs, like in the old
-build. How do I do that?
-**A:** You specify the `LOG` variable to make. There are several log levels:
-
- * **`warn`** -- Default and very quiet.
- * **`info`** -- Shows more progress information than warn.
- * **`debug`** -- Echos all command lines and prints all macro calls for
- compilation definitions.
- * **`trace`** -- Echos all $(shell) command lines as well.
-
-**Q:** When do I have to re-run `configure`?
-**A:** Normally you will run `configure` only once for creating a
-configuration. You need to re-run configuration only if you want to change any
-configuration options, or if you pull down changes to the `configure` script.
-
-**Q:** I have added a new source file. Do I need to modify the makefiles?
-**A:** Normally, no. If you want to create e.g. a new native library, you will
-need to modify the makefiles. But for normal file additions or removals, no
-changes are needed. There are certan exceptions for some native libraries where
-the source files are spread over many directories which also contain sources
-for other libraries. In these cases it was simply easier to create include
-lists rather than excludes.
-
-**Q:** When I run `configure --help`, I see many strange options, like
-`--dvidir`. What is this?
-**A:** Configure provides a slew of options by default, to all projects that
-use autoconf. Most of them are not used in OpenJDK, so you can safely ignore
-them. To list only OpenJDK specific features, use `configure --help=short`
-instead.
-
-**Q:** `configure` provides OpenJDK-specific features such as `--with-
-builddeps-server` that are not described in this document. What about those?
-**A:** Try them out if you like! But be aware that most of these are
-experimental features. Many of them don't do anything at all at the moment; the
-option is just a placeholder. Others depend on pieces of code or infrastructure
-that is currently not ready for prime time.
-
-**Q:** How will you make sure you don't break anything?
-**A:** We have a script that compares the result of the new build system with
-the result of the old. For most part, we aim for (and achieve) byte-by-byte
-identical output. There are however technical issues with e.g. native binaries,
-which might differ in a byte-by-byte comparison, even when building twice with
-the old build system. For these, we compare relevant aspects (e.g. the symbol
-table and file size). Note that we still don't have 100% equivalence, but we're
-close.
-
-**Q:** I noticed this thing X in the build that looks very broken by design.
-Why don't you fix it?
-**A:** Our goal is to produce a build output that is as close as technically
-possible to the old build output. If things were weird in the old build, they
-will be weird in the new build. Often, things were weird before due to
-obscurity, but in the new build system the weird stuff comes up to the surface.
-The plan is to attack these things at a later stage, after the new build system
-is established.
-
-**Q:** The code in the new build system is not that well-structured. Will you
-fix this?
-**A:** Yes! The new build system has grown bit by bit as we converted the old
-system. When all of the old build system is converted, we can take a step back
-and clean up the structure of the new build system. Some of this we plan to do
-before replacing the old build system and some will need to wait until after.
-
-**Q:** Is anything able to use the results of the new build's default make
-target?
-**A:** Yes, this is the minimal (or roughly minimal) set of compiled output
-needed for a developer to actually execute the newly built JDK. The idea is
-that in an incremental development fashion, when doing a normal make, you
-should only spend time recompiling what's changed (making it purely
-incremental) and only do the work that's needed to actually run and test your
-code. The packaging stuff that is part of the `images` target is not needed for
-a normal developer who wants to test his new code. Even if it's quite fast,
-it's still unnecessary. We're targeting sub-second incremental rebuilds! ;-)
-(Or, well, at least single-digit seconds...)
-
-**Q:** I usually set a specific environment variable when building, but I can't
-find the equivalent in the new build. What should I do?
-**A:** It might very well be that we have neglected to add support for an
-option that was actually used from outside the build system. Email us and we
-will add support for it!
-
-<a name="performance"></a>
-### Build Performance Tips
-
-Building OpenJDK requires a lot of horsepower. Some of the build tools can be
-adjusted to utilize more or less of resources such as parallel threads and
-memory. The `configure` script analyzes your system and selects reasonable
-values for such options based on your hardware. If you encounter resource
-problems, such as out of memory conditions, you can modify the detected values
-with:
-
- * **`--with-num-cores`** -- number of cores in the build system, e.g.
- `--with-num-cores=8`
- * **`--with-memory-size`** -- memory (in MB) available in the build system,
- e.g. `--with-memory-size=1024`
-
-It might also be necessary to specify the JVM arguments passed to the Bootstrap
-JDK, using e.g. `--with-boot-jdk-jvmargs="-Xmx8G -enableassertions"`. Doing
-this will override the default JVM arguments passed to the Bootstrap JDK.
-
-One of the top goals of the new build system is to improve the build
-performance and decrease the time needed to build. This will soon also apply to
-the java compilation when the Smart Javac wrapper is fully supported.
-
-At the end of a successful execution of `configure`, you will get a performance
-summary, indicating how well the build will perform. Here you will also get
-performance hints. If you want to build fast, pay attention to those!
-
-#### Building with ccache
-
-The OpenJDK build supports building with ccache when using gcc or clang. Using
-ccache can radically speed up compilation of native code if you often rebuild
-the same sources. Your milage may vary however so we recommend evaluating it
-for yourself. To enable it, make sure it's on the path and configure with
-`--enable-ccache`.
-
-#### Building on local disk
-
-If you are using network shares, e.g. via NFS, for your source code, make sure
-the build directory is situated on local disk. The performance penalty is
-extremely high for building on a network share, close to unusable.
-
-#### Building only one JVM
-
-The old build builds multiple JVMs on 32-bit systems (client and server; and on
-Windows kernel as well). In the new build we have changed this default to only
-build server when it's available. This improves build times for those not
-interested in multiple JVMs. To mimic the old behavior on platforms that
-support it, use `--with-jvm-variants=client,server`.
-
-#### Selecting the number of cores to build on
-
-By default, `configure` will analyze your machine and run the make process in
-parallel with as many threads as you have cores. This behavior can be
-overridden, either "permanently" (on a `configure` basis) using
-`--with-num-cores=N` or for a single build only (on a make basis), using
-`make JOBS=N`.
-
-If you want to make a slower build just this time, to save some CPU power for
-other processes, you can run e.g. `make JOBS=2`. This will force the makefiles
-to only run 2 parallel processes, or even `make JOBS=1` which will disable
-parallelism.
-
-If you want to have it the other way round, namely having slow builds default
-and override with fast if you're impatient, you should call `configure` with
-`--with-num-cores=2`, making 2 the default. If you want to run with more cores,
-run `make JOBS=8`
-
-<a name="troubleshooting"></a>
-### Troubleshooting
-
-#### Solving build problems
-
-If the build fails (and it's not due to a compilation error in a source file
-you've changed), the first thing you should do is to re-run the build with more
-verbosity. Do this by adding `LOG=debug` to your make command line.
-
-The build log (with both stdout and stderr intermingled, basically the same as
-you see on your console) can be found as `build.log` in your build directory.
-
-You can ask for help on build problems with the new build system on either the
-[build-dev](http://mail.openjdk.java.net/mailman/listinfo/build-dev) or the
-[build-infra-dev](http://mail.openjdk.java.net/mailman/listinfo/build-infra-dev)
-mailing lists. Please include the relevant parts of the build log.
-
-A build can fail for any number of reasons. Most failures are a result of
-trying to build in an environment in which all the pre-build requirements have
-not been met. The first step in troubleshooting a build failure is to recheck
-that you have satisfied all the pre-build requirements for your platform.
-Scanning the `configure` log is a good first step, making sure that what it
-found makes sense for your system. Look for strange error messages or any
-difficulties that `configure` had in finding things.
-
-Some of the more common problems with builds are briefly described below, with
-suggestions for remedies.
-
- * **Corrupted Bundles on Windows:**
- Some virus scanning software has been known to corrupt the downloading of
- zip bundles. It may be necessary to disable the 'on access' or 'real time'
- virus scanning features to prevent this corruption. This type of 'real time'
- virus scanning can also slow down the build process significantly.
- Temporarily disabling the feature, or excluding the build output directory
- may be necessary to get correct and faster builds.
-
- * **Slow Builds:**
- If your build machine seems to be overloaded from too many simultaneous C++
- compiles, try setting the `JOBS=1` on the `make` command line. Then try
- increasing the count slowly to an acceptable level for your system. Also:
-
- Creating the javadocs can be very slow, if you are running javadoc, consider
- skipping that step.
-
- Faster CPUs, more RAM, and a faster DISK usually helps. The VM build tends
- to be CPU intensive (many C++ compiles), and the rest of the JDK will often
- be disk intensive.
-
- Faster compiles are possible using a tool called
- [ccache](http://ccache.samba.org/).
-
- * **File time issues:**
- If you see warnings that refer to file time stamps, e.g.
-
- > _Warning message:_ ` File 'xxx' has modification time in the future.`
- > _Warning message:_ ` Clock skew detected. Your build may be incomplete.`
-
- These warnings can occur when the clock on the build machine is out of sync
- with the timestamps on the source files. Other errors, apparently unrelated
- but in fact caused by the clock skew, can occur along with the clock skew
- warnings. These secondary errors may tend to obscure the fact that the true
- root cause of the problem is an out-of-sync clock.
-
- If you see these warnings, reset the clock on the build machine, run
- "`gmake clobber`" or delete the directory containing the build output, and
- restart the build from the beginning.
-
- * **Error message: `Trouble writing out table to disk`**
- Increase the amount of swap space on your build machine. This could be
- caused by overloading the system and it may be necessary to use:
-
- > `make JOBS=1`
-
- to reduce the load on the system.
-
- * **Error Message: `libstdc++ not found`:**
- This is caused by a missing libstdc++.a library. This is installed as part
- of a specific package (e.g. libstdc++.so.devel.386). By default some 64-bit
- Linux versions (e.g. Fedora) only install the 64-bit version of the
- libstdc++ package. Various parts of the JDK build require a static link of
- the C++ runtime libraries to allow for maximum portability of the built
- images.
-
- * **Linux Error Message: `cannot restore segment prot after reloc`**
- This is probably an issue with SELinux (See [SELinux on
- Wikipedia](http://en.wikipedia.org/wiki/SELinux)). Parts of the VM is built
- without the `-fPIC` for performance reasons.
-
- To completely disable SELinux:
-
- 1. `$ su root`
- 2. `# system-config-securitylevel`
- 3. `In the window that appears, select the SELinux tab`
- 4. `Disable SELinux`
-
- Alternatively, instead of completely disabling it you could disable just
- this one check.
-
- 1. Select System->Administration->SELinux Management
- 2. In the SELinux Management Tool which appears, select "Boolean" from the
- menu on the left
- 3. Expand the "Memory Protection" group
- 4. Check the first item, labeled "Allow all unconfined executables to use
- libraries requiring text relocation ..."
-
- * **Windows Error Messages:**
- `*** fatal error - couldn't allocate heap, ... `
- `rm fails with "Directory not empty"`
- `unzip fails with "cannot create ... Permission denied"`
- `unzip fails with "cannot create ... Error 50"`
-
- The CYGWIN software can conflict with other non-CYGWIN software. See the
- CYGWIN FAQ section on [BLODA (applications that interfere with
- CYGWIN)](http://cygwin.com/faq/faq.using.html#faq.using.bloda).
-
- * **Windows Error Message: `spawn failed`**
- Try rebooting the system, or there could be some kind of issue with the disk
- or disk partition being used. Sometimes it comes with a "Permission Denied"
- message.

-<a name="gmake"></a>
-## Appendix B: GNU make
-
-The Makefiles in the OpenJDK are only valid when used with the GNU version of
-the utility command `make` (usually called `gmake` on Solaris). A few notes
-about using GNU make:
-
- * You need GNU make version 3.81 or newer. On Windows 4.0 or newer is
- recommended. If the GNU make utility on your systems is not of a suitable
- version, see "[Building GNU make](#buildgmake)".
- * Place the location of the GNU make binary in the `PATH`.
- * **Solaris:** Do NOT use `/usr/bin/make` on Solaris. If your Solaris system
- has the software from the Solaris Developer Companion CD installed, you
- should try and use `/usr/bin/gmake` or `/usr/gnu/bin/make`.
- * **Windows:** Make sure you start your build inside a bash shell.
- * **Mac OS X:** The XCode "command line tools" must be installed on your Mac.
-
-Information on GNU make, and access to ftp download sites, are available on the
-[GNU make web site ](http://www.gnu.org/software/make/make.html). The latest
-source to GNU make is available at
-[ftp.gnu.org/pub/gnu/make/](http://ftp.gnu.org/pub/gnu/make/).
-
-<a name="buildgmake"></a>
-### Building GNU make
-
-First step is to get the GNU make 3.81 or newer source from
-[ftp.gnu.org/pub/gnu/make/](http://ftp.gnu.org/pub/gnu/make/). Building is a
-little different depending on the OS but is basically done with:
-
- bash ./configure
- make

-## Appendix C: Build Environments
-
-### Minimum Build Environments
-
-This file often describes specific requirements for what we call the "minimum
-build environments" (MBE) for this specific release of the JDK. What is listed
-below is what the Oracle Release Engineering Team will use to build the Oracle
-JDK product. Building with the MBE will hopefully generate the most compatible
-bits that install on, and run correctly on, the most variations of the same
-base OS and hardware architecture. In some cases, these represent what is often
-called the least common denominator, but each Operating System has different
-aspects to it.
-
-In all cases, the Bootstrap JDK version minimum is critical, we cannot
-guarantee builds will work with older Bootstrap JDK's. Also in all cases, more
-RAM and more processors is better, the minimums listed below are simply
-recommendations.
-
-With Solaris and Mac OS X, the version listed below is the oldest release we
-can guarantee builds and works, and the specific version of the compilers used
-could be critical.
-
-With Windows the critical aspect is the Visual Studio compiler used, which due
-to it's runtime, generally dictates what Windows systems can do the builds and
-where the resulting bits can be used.
-
-**NOTE: We expect a change here off these older Windows OS releases and to a
-'less older' one, probably Windows 2008R2 X64.**
-
-With Linux, it was just a matter of picking a stable distribution that is a
-good representative for Linux in general.
-
-It is understood that most developers will NOT be using these specific
-versions, and in fact creating these specific versions may be difficult due to
-the age of some of this software. It is expected that developers are more often
-using the more recent releases and distributions of these operating systems.
-
-Compilation problems with newer or different C/C++ compilers is a common
-problem. Similarly, compilation problems related to changes to the
-`/usr/include` or system header files is also a common problem with older,
-newer, or unreleased OS versions. Please report these types of problems as bugs
-so that they can be dealt with accordingly.

-### Specific Developer Build Environments
-
-We won't be listing all the possible environments, but we will try to provide
-what information we have available to us.
-
-**NOTE: The community can help out by updating this part of the document.**
-
-#### Fedora
-
-After installing the latest [Fedora](http://fedoraproject.org) you need to
-install several build dependencies. The simplest way to do it is to execute the
-following commands as user `root`:
-
- yum-builddep java-1.7.0-openjdk
- yum install gcc gcc-c++
-
-In addition, it's necessary to set a few environment variables for the build:
-
- export LANG=C
- export PATH="/usr/lib/jvm/java-openjdk/bin:${PATH}"
-
-#### CentOS 5.5
-
-After installing [CentOS 5.5](http://www.centos.org/) you need to make sure you
-have the following Development bundles installed:
-
- * Development Libraries
- * Development Tools
- * Java Development
- * X Software Development (Including XFree86-devel)
-
-Plus the following packages:
-
- * cups devel: Cups Development Package
- * alsa devel: Alsa Development Package
- * Xi devel: libXi.so Development Package
-
-The freetype 2.3 packages don't seem to be available, but the freetype 2.3
-sources can be downloaded, built, and installed easily enough from [the
-freetype site](http://downloads.sourceforge.net/freetype). Build and install
-with something like:
-
- bash ./configure
- make
- sudo -u root make install
-
-Mercurial packages could not be found easily, but a Google search should find
-ones, and they usually include Python if it's needed.
-
-#### Debian 5.0 (Lenny)
-
-After installing [Debian](http://debian.org) 5 you need to install several
-build dependencies. The simplest way to install the build dependencies is to
-execute the following commands as user `root`:
-
- aptitude build-dep openjdk-7
- aptitude install openjdk-7-jdk libmotif-dev
-
-In addition, it's necessary to set a few environment variables for the build:
-
- export LANG=C
- export PATH="/usr/lib/jvm/java-7-openjdk/bin:${PATH}"
-
-#### Ubuntu 12.04
-
-After installing [Ubuntu](http://ubuntu.org) 12.04 you need to install several
-build dependencies. The simplest way to do it is to execute the following
-commands:
-
- sudo aptitude build-dep openjdk-7
- sudo aptitude install openjdk-7-jdk
-
-In addition, it's necessary to set a few environment variables for the build:
-
- export LANG=C
- export PATH="/usr/lib/jvm/java-7-openjdk/bin:${PATH}"
-
-#### OpenSUSE 11.1
-
-After installing [OpenSUSE](http://opensuse.org) 11.1 you need to install
-several build dependencies. The simplest way to install the build dependencies
-is to execute the following commands:
-
- sudo zypper source-install -d java-1_7_0-openjdk
- sudo zypper install make
-
-In addition, it is necessary to set a few environment variables for the build:
-
- export LANG=C
- export PATH="/usr/lib/jvm/java-1.7.0-openjdk/bin:$[PATH}"
-
-Finally, you need to unset the `JAVA_HOME` environment variable:
-
- export -n JAVA_HOME`
-
-#### Mandriva Linux One 2009 Spring
-
-After installing [Mandriva](http://mandriva.org) Linux One 2009 Spring you need
-to install several build dependencies. The simplest way to install the build
-dependencies is to execute the following commands as user `root`:
-

+<h2 id="introduction">Introduction</h2>
+<p>This README file contains build instructions for the <a href="http://openjdk.java.net">OpenJDK</a>. Building the source code for the OpenJDK requires a certain degree of technical expertise.</p>
+<h3 id="this-is-a-major-re-write-of-this-document.">!!!!!!!!!!!!!!! THIS IS A MAJOR RE-WRITE of this document. !!!!!!!!!!!!!</h3>
+<p>Some Headlines:</p>
+<ul>
+<li>The build is now a "<code>configure && make</code>" style build</li>
+<li>Any GNU make 3.81 or newer should work, except on Windows where 4.0 or newer is recommended.</li>
+<li>The build should scale, i.e. more processors should cause the build to be done in less wall-clock time</li>
+<li>Nested or recursive make invocations have been significantly reduced, as has the total fork/exec or spawning of sub processes during the build</li>
+<li>Windows MKS usage is no longer supported</li>
+<li>Windows Visual Studio <code>vsvars*.bat</code> and <code>vcvars*.bat</code> files are run automatically</li>
+<li>Ant is no longer used when building the OpenJDK</li>
+<li>Use of ALT_* environment variables for configuring the build is no longer supported</li>
+</ul>

+<h2 id="use-of-mercurial">Use of Mercurial</h2>
+<p>The OpenJDK sources are maintained with the revision control system <a href="http://mercurial.selenic.com/wiki/Mercurial">Mercurial</a>. If you are new to Mercurial, please see the <a href="http://mercurial.selenic.com/wiki/BeginnersGuides">Beginner Guides</a> or refer to the <a href="http://hgbook.red-bean.com/">Mercurial Book</a>. The first few chapters of the book provide an excellent overview of Mercurial, what it is and how it works.</p>
+<p>For using Mercurial with the OpenJDK refer to the <a href="http://openjdk.java.net/guide/repositories.html#installConfig">Developer Guide: Installing and Configuring Mercurial</a> section for more information.</p>
+<h3 id="getting-the-source">Getting the Source</h3>
+<p>To get the entire set of OpenJDK Mercurial repositories use the script <code>get_source.sh</code> located in the root repository:</p>
+<pre><code> hg clone http://hg.openjdk.java.net/jdk9/jdk9 YourOpenJDK
+ cd YourOpenJDK
+ bash ./get_source.sh</code></pre>
+<p>Once you have all the repositories, keep in mind that each repository is its own independent repository. You can also re-run <code>./get_source.sh</code> anytime to pull over all the latest changesets in all the repositories. This set of nested repositories has been given the term "forest" and there are various ways to apply the same <code>hg</code> command to each of the repositories. For example, the script <code>make/scripts/hgforest.sh</code> can be used to repeat the same <code>hg</code> command on every repository, e.g.</p>
+<pre><code> cd YourOpenJDK

+<h3 id="repository-source-guidelines">Repository Source Guidelines</h3>
+<p>There are some very basic guidelines:</p>
+<ul>
+<li>Use of whitespace in source files (.java, .c, .h, .cpp, and .hpp files) is restricted. No TABs, no trailing whitespace on lines, and files should not terminate in more than one blank line.</li>
+<li>Files with execute permissions should not be added to the source repositories.</li>
+<li>All generated files need to be kept isolated from the files maintained or managed by the source control system. The standard area for generated files is the top level <code>build/</code> directory.</li>
+<li>The default build process should be to build the product and nothing else, in one form, e.g. a product (optimized), debug (non-optimized, -g plus assert logic), or fastdebug (optimized, -g plus assert logic).</li>
+<li>The <code>.hgignore</code> file in each repository must exist and should include <code>^build/</code>, <code>^dist/</code> and optionally any <code>nbproject/private</code> directories. <strong>It should NEVER</strong> include anything in the <code>src/</code> or <code>test/</code> or any managed directory area of a repository.</li>
+<li>Directory names and file names should never contain blanks or non-printing characters.</li>
+<li>Generated source or binary files should NEVER be added to the repository (that includes <code>javah</code> output). There are some exceptions to this rule, in particular with some of the generated configure scripts.</li>
+<li>Files not needed for typical building or testing of the repository should not be added to the repository.</li>
+</ul>
+<hr />
+<h2 id="building">Building</h2>
+<p>The very first step in building the OpenJDK is making sure the system itself has everything it needs to do OpenJDK builds. Once a system is setup, it generally doesn't need to be done again.</p>
+<p>Building the OpenJDK is now done with running a <code>configure</code> script which will try and find and verify you have everything you need, followed by running <code>make</code>, e.g.</p>
+<blockquote>
+<p><strong><code>bash ./configure</code></strong><br />
+<strong><code>make all</code></strong></p>
+</blockquote>
+<p>Where possible the <code>configure</code> script will attempt to located the various components in the default locations or via component specific variable settings. When the normal defaults fail or components cannot be found, additional <code>configure</code> options may be necessary to help <code>configure</code> find the necessary tools for the build, or you may need to re-visit the setup of your system due to missing software packages.</p>
+<p><strong>NOTE:</strong> The <code>configure</code> script file does not have execute permissions and will need to be explicitly run with <code>bash</code>, see the source guidelines.</p>
+<hr />
+<h3 id="system-setup">System Setup</h3>
+<p>Before even attempting to use a system to build the OpenJDK there are some very basic system setups needed. For all systems:</p>
+<ul>
+<li>Be sure the GNU make utility is version 3.81 (4.0 on windows) or newer, e.g. run "<code>make -version</code>"</li>
+</ul>
+<p><a name="bootjdk"></a> * Install a Bootstrap JDK. All OpenJDK builds require access to a previously released JDK called the <em>bootstrap JDK</em> or <em>boot JDK.</em> The general rule is that the bootstrap JDK must be an instance of the previous major release of the JDK. In addition, there may be a requirement to use a release at or beyond a particular update level.</p>
+<p><strong><em>Building JDK 9 requires JDK 8. JDK 9 developers should not use JDK 9 as the boot JDK, to ensure that JDK 9 dependencies are not introduced into the parts of the system that are built with JDK 8.</em></strong></p>
+<p>The JDK 8 binaries can be downloaded from Oracle's <a href="http://www.oracle.com/technetwork/java/javase/downloads/index.html">JDK 8 download site</a>. For build performance reasons it is very important that this bootstrap JDK be made available on the local disk of the machine doing the build. You should add its <code>bin</code> directory to the <code>PATH</code> environment variable. If <code>configure</code> has any issues finding this JDK, you may need to use the <code>configure</code> option <code>--with-boot-jdk</code>.</p>
+<ul>
+<li>Ensure that GNU make, the Bootstrap JDK, and the compilers are all in your PATH environment variable.</li>
+</ul>
+<p>And for specific systems:</p>
+<ul>
+<li><strong>Linux</strong></li>
+</ul>
+<p>Install all the software development packages needed including <a href="#alsa">alsa</a>, <a href="#freetype">freetype</a>, <a href="#cups">cups</a>, and <a href="#xrender">xrender</a>. See <a href="#SDBE">specific system packages</a>.</p>

+<ul>
+<li><p><strong>Windows</strong></p></li>
+<li>Install one of <a href="#cygwin">CYGWIN</a> or <a href="#msys">MinGW/MSYS</a></li>
+<li><p>Install <a href="#vs2013">Visual Studio 2013</a></p></li>

+</ul>
+<p>Install <a href="https://developer.apple.com/xcode/">XCode 6.3</a></p>
+<h4 id="linux">Linux</h4>
+<p>With Linux, try and favor the system packages over building your own or getting packages from other areas. Most Linux builds should be possible with the system's available packages.</p>
+<p>Note that some Linux systems have a habit of pre-populating your environment variables for you, for example <code>JAVA_HOME</code> might get pre-defined for you to refer to the JDK installed on your Linux system. You will need to unset <code>JAVA_HOME</code>. It's a good idea to run <code>env</code> and verify the environment variables you are getting from the default system settings make sense for building the OpenJDK.</p>

+<h4 id="windows">Windows</h4>
+<h5 id="windows-unix-toolkit">Windows Unix Toolkit</h5>
+<p>Building on Windows requires a Unix-like environment, notably a Unix-like shell. There are several such environments available of which <a href="http://www.cygwin.com/">Cygwin</a> and <a href="http://www.mingw.org/wiki/MSYS">MinGW/MSYS</a> are currently supported for the OpenJDK build. One of the differences of these systems from standard Windows tools is the way they handle Windows path names, particularly path names which contain spaces, backslashes as path separators and possibly drive letters. Depending on the use case and the specifics of each environment these path problems can be solved by a combination of quoting whole paths, translating backslashes to forward slashes, escaping backslashes with additional backslashes and translating the path names to their <a href="http://en.wikipedia.org/wiki/8.3_filename">"8.3" version</a>.</p>
+<h6 id="cygwin">CYGWIN</h6>
+<p>CYGWIN is an open source, Linux-like environment which tries to emulate a complete POSIX layer on Windows. It tries to be smart about path names and can usually handle all kinds of paths if they are correctly quoted or escaped although internally it maps drive letters <code><drive>:</code> to a virtual directory <code>/cygdrive/<drive></code>.</p>
+<p>You can always use the <code>cygpath</code> utility to map pathnames with spaces or the backslash character into the <code>C:/</code> style of pathname (called 'mixed'), e.g. <code>cygpath -s -m "<path>"</code>.</p>
+<p>Note that the use of CYGWIN creates a unique problem with regards to setting <a href="#path"><code>PATH</code></a>. Normally on Windows the <code>PATH</code> variable contains directories separated with the ";" character (Solaris and Linux use ":"). With CYGWIN, it uses ":", but that means that paths like "C:/path" cannot be placed in the CYGWIN version of <code>PATH</code> and instead CYGWIN uses something like <code>/cygdrive/c/path</code> which CYGWIN understands, but only CYGWIN understands.</p>
+<p>The OpenJDK build requires CYGWIN version 1.7.16 or newer. Information about CYGWIN can be obtained from the CYGWIN website at <a href="http://www.cygwin.com">www.cygwin.com</a>.</p>
+<p>By default CYGWIN doesn't install all the tools required for building the OpenJDK. Along with the default installation, you need to install the following tools.</p>

+<h6 id="mingwmsys">MinGW/MSYS</h6>
+<p>MinGW ("Minimalist GNU for Windows") is a collection of free Windows specific header files and import libraries combined with GNU toolsets that allow one to produce native Windows programs that do not rely on any 3rd-party C runtime DLLs. MSYS is a supplement to MinGW which allows building applications and programs which rely on traditional UNIX tools to be present. Among others this includes tools like <code>bash</code> and <code>make</code>. See <a href="http://www.mingw.org/wiki/MSYS">MinGW/MSYS</a> for more information.</p>
+<p>Like Cygwin, MinGW/MSYS can handle different types of path formats. They are internally converted to paths with forward slashes and drive letters <code><drive>:</code> replaced by a virtual directory <code>/<drive></code>. Additionally, MSYS automatically detects binaries compiled for the MSYS environment and feeds them with the internal, Unix-style path names. If native Windows applications are called from within MSYS programs their path arguments are automatically converted back to Windows style path names with drive letters and backslashes as path separators. This may cause problems for Windows applications which use forward slashes as parameter separator (e.g. <code>cl /nologo /I</code>) because MSYS may wrongly <a href="http://mingw.org/wiki/Posix_path_conversion">replace such parameters by drive letters</a>.</p>
+<p>In addition to the tools which will be installed by default, you have to manually install the <code>msys-zip</code> and <code>msys-unzip</code> packages. This can be easily done with the MinGW command line installer:</p>
+<pre><code> mingw-get.exe install msys-zip
+ mingw-get.exe install msys-unzip</code></pre>
+<h5 id="visual-studio-2013-compilers">Visual Studio 2013 Compilers</h5>
+<p>The 32-bit and 64-bit OpenJDK Windows build requires Microsoft Visual Studio C++ 2013 (VS2013) Professional Edition or Express compiler. The compiler and other tools are expected to reside in the location defined by the variable <code>VS120COMNTOOLS</code> which is set by the Microsoft Visual Studio installer.</p>
+<p>Only the C++ part of VS2013 is needed. Try to let the installation go to the default install directory. Always reboot your system after installing VS2013. The system environment variable VS120COMNTOOLS should be set in your environment.</p>
+<p>Make sure that TMP and TEMP are also set in the environment and refer to Windows paths that exist, like <code>C:\temp</code>, not <code>/tmp</code>, not <code>/cygdrive/c/temp</code>, and not <code>C:/temp</code>. <code>C:\temp</code> is just an example, it is assumed that this area is private to the user, so by default after installs you should see a unique user path in these variables.</p>

+<h3 id="configure">Configure</h3>
+<p>The basic invocation of the <code>configure</code> script looks like:</p>
+<blockquote>
+<p><strong><code>bash ./configure [options]</code></strong></p>
+</blockquote>
+<p>This will create an output directory containing the "configuration" and setup an area for the build result. This directory typically looks like:</p>
+<blockquote>
+<p><strong><code>build/linux-x64-normal-server-release</code></strong></p>
+</blockquote>
+<p><code>configure</code> will try to figure out what system you are running on and where all necessary build components are. If you have all prerequisites for building installed, it should find everything. If it fails to detect any component automatically, it will exit and inform you about the problem. When this happens, read more below in <a href="#configureoptions">the <code>configure</code> options</a>.</p>
+<p>Some examples:</p>
+<blockquote>
+<p><strong>Windows 32bit build with freetype specified:</strong><br />
+<code>bash ./configure --with-freetype=/cygdrive/c/freetype-i586 --with-target-bits=32</code></p>

+<code>bash ./configure --enable-debug --with-target-bits=64</code></p>
+</blockquote>

+<p>Use <code>-help</code> to see all the <code>configure</code> options available. You can generate any number of different configurations, e.g. debug, release, 32, 64, etc.</p>
+<p>Some of the more commonly used <code>configure</code> options are:</p>
+<blockquote>
+<p><strong><code>--enable-debug</code></strong><br />

+<blockquote>
+<p>See <a href="http://en.wikipedia.org/wiki/Certificate_Authority">Certificate Authority on Wikipedia</a> for a better understanding of the Certificate Authority (CA). A certificates file named "cacerts" represents a system-wide keystore with CA certificates. In JDK and JRE binary bundles, the "cacerts" file contains root CA certificates from several public CAs (e.g., VeriSign, Thawte, and Baltimore). The source contain a cacerts file without CA root certificates. Formal JDK builders will need to secure permission from each public CA and include the certificates into their own custom cacerts file. Failure to provide a populated cacerts file will result in verification errors of a certificate chain during runtime. By default an empty cacerts file is provided and that should be fine for most JDK developers.</p>

+<h3 id="faq">FAQ</h3>
+<p><strong>Q:</strong> The <code>generated-configure.sh</code> file looks horrible! How are you going to edit it?<br />
+<strong>A:</strong> The <code>generated-configure.sh</code> file is generated (think "compiled") by the autoconf tools. The source code is in <code>configure.ac</code> and various .m4 files in common/autoconf, which are much more readable.</p>
+<p><strong>Q:</strong> Why is the <code>generated-configure.sh</code> file checked in, if it is generated?<br />
+<strong>A:</strong> If it was not generated, every user would need to have the autoconf tools installed, and re-generate the <code>configure</code> file as the first step. Our goal is to minimize the work needed to be done by the user to start building OpenJDK, and to minimize the number of external dependencies required.</p>
+<p><strong>Q:</strong> Do you require a specific version of autoconf for regenerating <code>generated-configure.sh</code>?<br />
+<strong>A:</strong> Yes, version 2.69 is required and should be easy enough to aquire on all supported operating systems. The reason for this is to avoid large spurious changes in <code>generated-configure.sh</code>.</p>
+<p><strong>Q:</strong> How do you regenerate <code>generated-configure.sh</code> after making changes to the input files?<br />
+<strong>A:</strong> Regnerating <code>generated-configure.sh</code> should always be done using the script <code>common/autoconf/autogen.sh</code> to ensure that the correct files get updated. This script should also be run after mercurial tries to merge <code>generated-configure.sh</code> as a merge of the generated file is not guaranteed to be correct.</p>
+<p><strong>Q:</strong> What are the files in <code>common/makefiles/support/*</code> for? They look like gibberish.<br />
+<strong>A:</strong> They are a somewhat ugly hack to compensate for command line length limitations on certain platforms (Windows, Solaris). Due to a combination of limitations in make and the shell, command lines containing too many files will not work properly. These helper files are part of an elaborate hack that will compress the command line in the makefile and then uncompress it safely. We're not proud of it, but it does fix the problem. If you have any better suggestions, we're all ears! :-)</p>
+<p><strong>Q:</strong> I want to see the output of the commands that make runs, like in the old build. How do I do that?<br />
+<strong>A:</strong> You specify the <code>LOG</code> variable to make. There are several log levels:</p>
+<ul>
+<li><strong><code>warn</code></strong> -- Default and very quiet.</li>
+<li><strong><code>info</code></strong> -- Shows more progress information than warn.</li>
+<li><strong><code>debug</code></strong> -- Echos all command lines and prints all macro calls for compilation definitions.</li>
+<li><strong><code>trace</code></strong> -- Echos all $(shell) command lines as well.</li>
+</ul>
+<p><strong>Q:</strong> When do I have to re-run <code>configure</code>?<br />
+<strong>A:</strong> Normally you will run <code>configure</code> only once for creating a configuration. You need to re-run configuration only if you want to change any configuration options, or if you pull down changes to the <code>configure</code> script.</p>
+<p><strong>Q:</strong> I have added a new source file. Do I need to modify the makefiles?<br />
+<strong>A:</strong> Normally, no. If you want to create e.g. a new native library, you will need to modify the makefiles. But for normal file additions or removals, no changes are needed. There are certan exceptions for some native libraries where the source files are spread over many directories which also contain sources for other libraries. In these cases it was simply easier to create include lists rather than excludes.</p>
+<p><strong>Q:</strong> When I run <code>configure --help</code>, I see many strange options, like <code>--dvidir</code>. What is this?<br />
+<strong>A:</strong> Configure provides a slew of options by default, to all projects that use autoconf. Most of them are not used in OpenJDK, so you can safely ignore them. To list only OpenJDK specific features, use <code>configure --help=short</code> instead.</p>
+<p><strong>Q:</strong> <code>configure</code> provides OpenJDK-specific features such as <code>--with-builddeps-server</code> that are not described in this document. What about those?<br />
+<strong>A:</strong> Try them out if you like! But be aware that most of these are experimental features. Many of them don't do anything at all at the moment; the option is just a placeholder. Others depend on pieces of code or infrastructure that is currently not ready for prime time.</p>
+<p><strong>Q:</strong> How will you make sure you don't break anything?<br />
+<strong>A:</strong> We have a script that compares the result of the new build system with the result of the old. For most part, we aim for (and achieve) byte-by-byte identical output. There are however technical issues with e.g. native binaries, which might differ in a byte-by-byte comparison, even when building twice with the old build system. For these, we compare relevant aspects (e.g. the symbol table and file size). Note that we still don't have 100% equivalence, but we're close.</p>
+<p><strong>Q:</strong> I noticed this thing X in the build that looks very broken by design. Why don't you fix it?<br />
+<strong>A:</strong> Our goal is to produce a build output that is as close as technically possible to the old build output. If things were weird in the old build, they will be weird in the new build. Often, things were weird before due to obscurity, but in the new build system the weird stuff comes up to the surface. The plan is to attack these things at a later stage, after the new build system is established.</p>
+<p><strong>Q:</strong> The code in the new build system is not that well-structured. Will you fix this?<br />
+<strong>A:</strong> Yes! The new build system has grown bit by bit as we converted the old system. When all of the old build system is converted, we can take a step back and clean up the structure of the new build system. Some of this we plan to do before replacing the old build system and some will need to wait until after.</p>
+<p><strong>Q:</strong> Is anything able to use the results of the new build's default make target?<br />
+<strong>A:</strong> Yes, this is the minimal (or roughly minimal) set of compiled output needed for a developer to actually execute the newly built JDK. The idea is that in an incremental development fashion, when doing a normal make, you should only spend time recompiling what's changed (making it purely incremental) and only do the work that's needed to actually run and test your code. The packaging stuff that is part of the <code>images</code> target is not needed for a normal developer who wants to test his new code. Even if it's quite fast, it's still unnecessary. We're targeting sub-second incremental rebuilds! ;-) (Or, well, at least single-digit seconds...)</p>
+<p><strong>Q:</strong> I usually set a specific environment variable when building, but I can't find the equivalent in the new build. What should I do?<br />
+<strong>A:</strong> It might very well be that we have neglected to add support for an option that was actually used from outside the build system. Email us and we will add support for it!</p>
+<h3 id="build-performance-tips">Build Performance Tips</h3>
+<p>Building OpenJDK requires a lot of horsepower. Some of the build tools can be adjusted to utilize more or less of resources such as parallel threads and memory. The <code>configure</code> script analyzes your system and selects reasonable values for such options based on your hardware. If you encounter resource problems, such as out of memory conditions, you can modify the detected values with:</p>
+<ul>
+<li><strong><code>--with-num-cores</code></strong> -- number of cores in the build system, e.g. <code>--with-num-cores=8</code></li>
+<li><strong><code>--with-memory-size</code></strong> -- memory (in MB) available in the build system, e.g. <code>--with-memory-size=1024</code></li>
+</ul>
+<p>It might also be necessary to specify the JVM arguments passed to the Bootstrap JDK, using e.g. <code>--with-boot-jdk-jvmargs="-Xmx8G -enableassertions"</code>. Doing this will override the default JVM arguments passed to the Bootstrap JDK.</p>
+<p>One of the top goals of the new build system is to improve the build performance and decrease the time needed to build. This will soon also apply to the java compilation when the Smart Javac wrapper is fully supported.</p>
+<p>At the end of a successful execution of <code>configure</code>, you will get a performance summary, indicating how well the build will perform. Here you will also get performance hints. If you want to build fast, pay attention to those!</p>
+<h4 id="building-with-ccache">Building with ccache</h4>
+<p>The OpenJDK build supports building with ccache when using gcc or clang. Using ccache can radically speed up compilation of native code if you often rebuild the same sources. Your milage may vary however so we recommend evaluating it for yourself. To enable it, make sure it's on the path and configure with <code>--enable-ccache</code>.</p>
+<h4 id="building-on-local-disk">Building on local disk</h4>
+<p>If you are using network shares, e.g. via NFS, for your source code, make sure the build directory is situated on local disk. The performance penalty is extremely high for building on a network share, close to unusable.</p>
+<h4 id="building-only-one-jvm">Building only one JVM</h4>
+<p>The old build builds multiple JVMs on 32-bit systems (client and server; and on Windows kernel as well). In the new build we have changed this default to only build server when it's available. This improves build times for those not interested in multiple JVMs. To mimic the old behavior on platforms that support it, use <code>--with-jvm-variants=client,server</code>.</p>
+<h4 id="selecting-the-number-of-cores-to-build-on">Selecting the number of cores to build on</h4>
+<p>By default, <code>configure</code> will analyze your machine and run the make process in parallel with as many threads as you have cores. This behavior can be overridden, either "permanently" (on a <code>configure</code> basis) using <code>--with-num-cores=N</code> or for a single build only (on a make basis), using <code>make JOBS=N</code>.</p>
+<p>If you want to make a slower build just this time, to save some CPU power for other processes, you can run e.g. <code>make JOBS=2</code>. This will force the makefiles to only run 2 parallel processes, or even <code>make JOBS=1</code> which will disable parallelism.</p>
+<p>If you want to have it the other way round, namely having slow builds default and override with fast if you're impatient, you should call <code>configure</code> with <code>--with-num-cores=2</code>, making 2 the default. If you want to run with more cores, run <code>make JOBS=8</code></p>
+<h3 id="troubleshooting">Troubleshooting</h3>
+<h4 id="solving-build-problems">Solving build problems</h4>
+<p>If the build fails (and it's not due to a compilation error in a source file you've changed), the first thing you should do is to re-run the build with more verbosity. Do this by adding <code>LOG=debug</code> to your make command line.</p>
+<p>The build log (with both stdout and stderr intermingled, basically the same as you see on your console) can be found as <code>build.log</code> in your build directory.</p>
+<p>You can ask for help on build problems with the new build system on either the <a href="http://mail.openjdk.java.net/mailman/listinfo/build-dev">build-dev</a> or the <a href="http://mail.openjdk.java.net/mailman/listinfo/build-infra-dev">build-infra-dev</a> mailing lists. Please include the relevant parts of the build log.</p>
+<p>A build can fail for any number of reasons. Most failures are a result of trying to build in an environment in which all the pre-build requirements have not been met. The first step in troubleshooting a build failure is to recheck that you have satisfied all the pre-build requirements for your platform. Scanning the <code>configure</code> log is a good first step, making sure that what it found makes sense for your system. Look for strange error messages or any difficulties that <code>configure</code> had in finding things.</p>
+<p>Some of the more common problems with builds are briefly described below, with suggestions for remedies.</p>
+<ul>
+<li><p><strong>Corrupted Bundles on Windows:</strong><br />
+Some virus scanning software has been known to corrupt the downloading of zip bundles. It may be necessary to disable the 'on access' or 'real time' virus scanning features to prevent this corruption. This type of 'real time' virus scanning can also slow down the build process significantly. Temporarily disabling the feature, or excluding the build output directory may be necessary to get correct and faster builds.</p></li>
+<li><p><strong>Slow Builds:</strong><br />
+If your build machine seems to be overloaded from too many simultaneous C++ compiles, try setting the <code>JOBS=1</code> on the <code>make</code> command line. Then try increasing the count slowly to an acceptable level for your system. Also:</p></li>
+</ul>
+<p>Creating the javadocs can be very slow, if you are running javadoc, consider skipping that step.</p>
+<p>Faster CPUs, more RAM, and a faster DISK usually helps. The VM build tends to be CPU intensive (many C++ compiles), and the rest of the JDK will often be disk intensive.</p>
+<p>Faster compiles are possible using a tool called <a href="http://ccache.samba.org/">ccache</a>.</p>
+<ul>
+<li><strong>File time issues:</strong><br />
+If you see warnings that refer to file time stamps, e.g.</li>
+</ul>
+<blockquote>
+<p><em>Warning message:</em> <code>File 'xxx' has modification time in the future.</code><br />
+<em>Warning message:</em> <code>Clock skew detected. Your build may be incomplete.</code></p>
+</blockquote>
+<p>These warnings can occur when the clock on the build machine is out of sync with the timestamps on the source files. Other errors, apparently unrelated but in fact caused by the clock skew, can occur along with the clock skew warnings. These secondary errors may tend to obscure the fact that the true root cause of the problem is an out-of-sync clock.</p>
+<p>If you see these warnings, reset the clock on the build machine, run "<code>gmake clobber</code>" or delete the directory containing the build output, and restart the build from the beginning.</p>
+<ul>
+<li><strong>Error message: <code>Trouble writing out table to disk</code></strong><br />
+Increase the amount of swap space on your build machine. This could be caused by overloading the system and it may be necessary to use:</li>
+</ul>
+<blockquote>
+<p><code>make JOBS=1</code></p>
+</blockquote>
+<p>to reduce the load on the system.</p>
+<ul>
+<li><p><strong>Error Message: <code>libstdc++ not found</code>:</strong><br />
+This is caused by a missing libstdc++.a library. This is installed as part of a specific package (e.g. libstdc++.so.devel.386). By default some 64-bit Linux versions (e.g. Fedora) only install the 64-bit version of the libstdc++ package. Various parts of the JDK build require a static link of the C++ runtime libraries to allow for maximum portability of the built images.</p></li>
+<li><p><strong>Linux Error Message: <code>cannot restore segment prot after reloc</code></strong><br />
+This is probably an issue with SELinux (See <a href="http://en.wikipedia.org/wiki/SELinux">SELinux on Wikipedia</a>). Parts of the VM is built without the <code>-fPIC</code> for performance reasons.</p></li>
+</ul>
+<p>To completely disable SELinux:</p>
+<ol style="list-style-type: decimal">
+<li><code>$ su root</code></li>
+<li><code># system-config-securitylevel</code></li>
+<li><code>In the window that appears, select the SELinux tab</code></li>
+<li><code>Disable SELinux</code></li>
+</ol>
+<p>Alternatively, instead of completely disabling it you could disable just this one check.</p>
+<ol style="list-style-type: decimal">
+<li>Select System->Administration->SELinux Management</li>
+<li>In the SELinux Management Tool which appears, select "Boolean" from the menu on the left</li>
+<li>Expand the "Memory Protection" group</li>
+<li>Check the first item, labeled "Allow all unconfined executables to use libraries requiring text relocation ..."</li>
+</ol>
+<ul>
+<li><strong>Windows Error Messages:</strong><br />
+<code>*** fatal error - couldn't allocate heap, ...</code><br />
+<code>rm fails with "Directory not empty"</code><br />
+<code>unzip fails with "cannot create ... Permission denied"</code><br />
+<code>unzip fails with "cannot create ... Error 50"</code></li>
+</ul>
+<p>The CYGWIN software can conflict with other non-CYGWIN software. See the CYGWIN FAQ section on <a href="http://cygwin.com/faq/faq.using.html#faq.using.bloda">BLODA (applications that interfere with CYGWIN)</a>.</p>
+<ul>
+<li><strong>Windows Error Message: <code>spawn failed</code></strong><br />
+Try rebooting the system, or there could be some kind of issue with the disk or disk partition being used. Sometimes it comes with a "Permission Denied" message.</li>
+</ul>
+<hr />
+<h2 id="appendix-b-gnu-make">Appendix B: GNU make</h2>
+<p>The Makefiles in the OpenJDK are only valid when used with the GNU version of the utility command <code>make</code> (usually called <code>gmake</code> on Solaris). A few notes about using GNU make:</p>
+<ul>
+<li>You need GNU make version 3.81 or newer. On Windows 4.0 or newer is recommended. If the GNU make utility on your systems is not of a suitable version, see "<a href="#buildgmake">Building GNU make</a>".</li>
+<li>Place the location of the GNU make binary in the <code>PATH</code>.</li>
+<li><strong>Solaris:</strong> Do NOT use <code>/usr/bin/make</code> on Solaris. If your Solaris system has the software from the Solaris Developer Companion CD installed, you should try and use <code>/usr/bin/gmake</code> or <code>/usr/gnu/bin/make</code>.</li>
+<li><strong>Windows:</strong> Make sure you start your build inside a bash shell.</li>
+<li><strong>Mac OS X:</strong> The XCode "command line tools" must be installed on your Mac.</li>
+</ul>
+<p>Information on GNU make, and access to ftp download sites, are available on the <a href="http://www.gnu.org/software/make/make.html">GNU make web site</a>. The latest source to GNU make is available at <a href="http://ftp.gnu.org/pub/gnu/make/">ftp.gnu.org/pub/gnu/make/</a>.</p>
+<h3 id="building-gnu-make">Building GNU make</h3>
+<p>First step is to get the GNU make 3.81 or newer source from <a href="http://ftp.gnu.org/pub/gnu/make/">ftp.gnu.org/pub/gnu/make/</a>. Building is a little different depending on the OS but is basically done with:</p>
+<pre><code> bash ./configure
+ make</code></pre>
+<hr />
+<h2 id="appendix-c-build-environments">Appendix C: Build Environments</h2>
+<h3 id="minimum-build-environments">Minimum Build Environments</h3>
+<p>This file often describes specific requirements for what we call the "minimum build environments" (MBE) for this specific release of the JDK. What is listed below is what the Oracle Release Engineering Team will use to build the Oracle JDK product. Building with the MBE will hopefully generate the most compatible bits that install on, and run correctly on, the most variations of the same base OS and hardware architecture. In some cases, these represent what is often called the least common denominator, but each Operating System has different aspects to it.</p>
+<p>In all cases, the Bootstrap JDK version minimum is critical, we cannot guarantee builds will work with older Bootstrap JDK's. Also in all cases, more RAM and more processors is better, the minimums listed below are simply recommendations.</p>
+<p>With Solaris and Mac OS X, the version listed below is the oldest release we can guarantee builds and works, and the specific version of the compilers used could be critical.</p>
+<p>With Windows the critical aspect is the Visual Studio compiler used, which due to it's runtime, generally dictates what Windows systems can do the builds and where the resulting bits can be used.</p>
+<p><strong>NOTE: We expect a change here off these older Windows OS releases and to a 'less older' one, probably Windows 2008R2 X64.</strong></p>
+<p>With Linux, it was just a matter of picking a stable distribution that is a good representative for Linux in general.</p>
+<p>It is understood that most developers will NOT be using these specific versions, and in fact creating these specific versions may be difficult due to the age of some of this software. It is expected that developers are more often using the more recent releases and distributions of these operating systems.</p>
+<p>Compilation problems with newer or different C/C++ compilers is a common problem. Similarly, compilation problems related to changes to the <code>/usr/include</code> or system header files is also a common problem with older, newer, or unreleased OS versions. Please report these types of problems as bugs so that they can be dealt with accordingly.</p>

+% OpenJDK Build README
+
+
+
+--------------------------------------------------------------------------------
+
+## Introduction
+
+This README file contains build instructions for the
+[OpenJDK](http://openjdk.java.net). Building the source code for the OpenJDK
+requires a certain degree of technical expertise.
+
+### !!!!!!!!!!!!!!! THIS IS A MAJOR RE-WRITE of this document. !!!!!!!!!!!!!
+
+Some Headlines:
+
+ * The build is now a "`configure && make`" style build
+ * Any GNU make 3.81 or newer should work, except on Windows where 4.0 or newer
+ is recommended.
+ * The build should scale, i.e. more processors should cause the build to be
+ done in less wall-clock time
+ * Nested or recursive make invocations have been significantly reduced, as
+ has the total fork/exec or spawning of sub processes during the build
+ * Windows MKS usage is no longer supported
+ * Windows Visual Studio `vsvars*.bat` and `vcvars*.bat` files are run
+ automatically
+ * Ant is no longer used when building the OpenJDK
+ * Use of ALT\_\* environment variables for configuring the build is no longer
+ supported

+
+## Use of Mercurial
+
+The OpenJDK sources are maintained with the revision control system
+[Mercurial](http://mercurial.selenic.com/wiki/Mercurial). If you are new to
+Mercurial, please see the [Beginner
+Guides](http://mercurial.selenic.com/wiki/BeginnersGuides) or refer to the
+[Mercurial Book](http://hgbook.red-bean.com/). The first few chapters of the
+book provide an excellent overview of Mercurial, what it is and how it works.
+
+For using Mercurial with the OpenJDK refer to the [Developer Guide: Installing
+and Configuring
+Mercurial](http://openjdk.java.net/guide/repositories.html#installConfig)
+section for more information.
+
+### Getting the Source
+
+To get the entire set of OpenJDK Mercurial repositories use the script
+`get_source.sh` located in the root repository:
+
+ hg clone http://hg.openjdk.java.net/jdk9/jdk9 YourOpenJDK
+ cd YourOpenJDK
+ bash ./get_source.sh
+
+Once you have all the repositories, keep in mind that each repository is its
+own independent repository. You can also re-run `./get_source.sh` anytime to
+pull over all the latest changesets in all the repositories. This set of nested
+repositories has been given the term "forest" and there are various ways to
+apply the same `hg` command to each of the repositories. For example, the
+script `make/scripts/hgforest.sh` can be used to repeat the same `hg` command
+on every repository, e.g.
+
+ cd YourOpenJDK
+ bash ./make/scripts/hgforest.sh status
+
+### Repositories
+
+The set of repositories and what they contain:
+
+ * **. (root)** contains common configure and makefile logic
+ * **hotspot** contains source code and make files for building the OpenJDK
+ Hotspot Virtual Machine
+ * **langtools** contains source code for the OpenJDK javac and language tools
+ * **jdk** contains source code and make files for building the OpenJDK runtime
+ libraries and misc files
+ * **jaxp** contains source code for the OpenJDK JAXP functionality
+ * **jaxws** contains source code for the OpenJDK JAX-WS functionality
+ * **corba** contains source code for the OpenJDK Corba functionality
+ * **nashorn** contains source code for the OpenJDK JavaScript implementation
+
+### Repository Source Guidelines
+
+There are some very basic guidelines:
+
+ * Use of whitespace in source files (.java, .c, .h, .cpp, and .hpp files) is
+ restricted. No TABs, no trailing whitespace on lines, and files should not
+ terminate in more than one blank line.
+ * Files with execute permissions should not be added to the source
+ repositories.
+ * All generated files need to be kept isolated from the files maintained or
+ managed by the source control system. The standard area for generated files
+ is the top level `build/` directory.
+ * The default build process should be to build the product and nothing else,
+ in one form, e.g. a product (optimized), debug (non-optimized, -g plus
+ assert logic), or fastdebug (optimized, -g plus assert logic).
+ * The `.hgignore` file in each repository must exist and should include
+ `^build/`, `^dist/` and optionally any `nbproject/private` directories. **It
+ should NEVER** include anything in the `src/` or `test/` or any managed
+ directory area of a repository.
+ * Directory names and file names should never contain blanks or non-printing
+ characters.
+ * Generated source or binary files should NEVER be added to the repository
+ (that includes `javah` output). There are some exceptions to this rule, in
+ particular with some of the generated configure scripts.
+ * Files not needed for typical building or testing of the repository should
+ not be added to the repository.
+
+-------------------------------------------------------------------------------
+
+## Building
+
+The very first step in building the OpenJDK is making sure the system itself
+has everything it needs to do OpenJDK builds. Once a system is setup, it
+generally doesn't need to be done again.
+
+Building the OpenJDK is now done with running a `configure` script which will
+try and find and verify you have everything you need, followed by running
+`make`, e.g.
+
+> **`bash ./configure`** \
+> **`make all`**
+
+Where possible the `configure` script will attempt to located the various
+components in the default locations or via component specific variable
+settings. When the normal defaults fail or components cannot be found,
+additional `configure` options may be necessary to help `configure` find the
+necessary tools for the build, or you may need to re-visit the setup of your
+system due to missing software packages.
+
+**NOTE:** The `configure` script file does not have execute permissions and
+will need to be explicitly run with `bash`, see the source guidelines.
+
+-------------------------------------------------------------------------------
+
+### System Setup
+
+Before even attempting to use a system to build the OpenJDK there are some very
+basic system setups needed. For all systems:
+
+ * Be sure the GNU make utility is version 3.81 (4.0 on windows) or newer, e.g.
+ run "`make -version`"
+
+ <a name="bootjdk"></a>
+ * Install a Bootstrap JDK. All OpenJDK builds require access to a previously
+ released JDK called the *bootstrap JDK* or *boot JDK.* The general rule is
+ that the bootstrap JDK must be an instance of the previous major release of
+ the JDK. In addition, there may be a requirement to use a release at or
+ beyond a particular update level.
+
+ ***Building JDK 9 requires JDK 8. JDK 9 developers should not use JDK 9 as
+ the boot JDK, to ensure that JDK 9 dependencies are not introduced into the
+ parts of the system that are built with JDK 8.***
+
+ The JDK 8 binaries can be downloaded from Oracle's [JDK 8 download
+ site](http://www.oracle.com/technetwork/java/javase/downloads/index.html).
+ For build performance reasons it is very important that this bootstrap JDK
+ be made available on the local disk of the machine doing the build. You
+ should add its `bin` directory to the `PATH` environment variable. If
+ `configure` has any issues finding this JDK, you may need to use the
+ `configure` option `--with-boot-jdk`.
+
+ * Ensure that GNU make, the Bootstrap JDK, and the compilers are all in your
+ PATH environment variable.
+
+And for specific systems:
+
+ * **Linux**
+
+ Install all the software development packages needed including
+ [alsa](#alsa), [freetype](#freetype), [cups](#cups), and
+ [xrender](#xrender). See [specific system packages](#SDBE).
+
+ * **Solaris**
+
+ Install all the software development packages needed including [Studio
+ Compilers](#studio), [freetype](#freetype), [cups](#cups), and
+ [xrender](#xrender). See [specific system packages](#SDBE).
+
+ * **Windows**
+
+ * Install one of [CYGWIN](#cygwin) or [MinGW/MSYS](#msys)
+ * Install [Visual Studio 2013](#vs2013)
+
+ * **Mac OS X**
+
+ Install [XCode 6.3](https://developer.apple.com/xcode/)
+
+#### Linux
+
+With Linux, try and favor the system packages over building your own or getting
+packages from other areas. Most Linux builds should be possible with the
+system's available packages.
+
+Note that some Linux systems have a habit of pre-populating your environment
+variables for you, for example `JAVA_HOME` might get pre-defined for you to
+refer to the JDK installed on your Linux system. You will need to unset
+`JAVA_HOME`. It's a good idea to run `env` and verify the environment variables
+you are getting from the default system settings make sense for building the
+OpenJDK.
+
+#### Solaris
+
+##### Studio Compilers
+
+At a minimum, the [Studio 12 Update 4
+Compilers](http://www.oracle.com/technetwork/server-storage/solarisstudio/downloads/index.htm)
+(containing version 5.13 of the C and C++ compilers) is required, including
+specific patches.
+
+The Solaris Studio installation should contain at least these packages:
+
+ Package Version
+ -------------------------------------------------- ---------------
+ developer/solarisstudio-124/backend 12.4-1.0.6.0
+ developer/solarisstudio-124/c++ 12.4-1.0.10.0
+ developer/solarisstudio-124/cc 12.4-1.0.4.0
+ developer/solarisstudio-124/library/c++-libs 12.4-1.0.10.0
+ developer/solarisstudio-124/library/math-libs 12.4-1.0.0.1
+ developer/solarisstudio-124/library/studio-gccrt 12.4-1.0.0.1
+ developer/solarisstudio-124/studio-common 12.4-1.0.0.1
+ developer/solarisstudio-124/studio-ja 12.4-1.0.0.1
+ developer/solarisstudio-124/studio-legal 12.4-1.0.0.1
+ developer/solarisstudio-124/studio-zhCN 12.4-1.0.0.1
+
+In particular backend 12.4-1.0.6.0 contains a critical patch for the sparc
+version.
+
+Place the `bin` directory in `PATH`.
+
+The Oracle Solaris Studio Express compilers at: [Oracle Solaris Studio Express
+Download
+site](http://www.oracle.com/technetwork/server-storage/solarisstudio/downloads/index-jsp-142582.html)
+are also an option, although these compilers have not been extensively used
+yet.
+
+#### Windows
+
+##### Windows Unix Toolkit
+
+Building on Windows requires a Unix-like environment, notably a Unix-like
+shell. There are several such environments available of which
+[Cygwin](http://www.cygwin.com/) and
+[MinGW/MSYS](http://www.mingw.org/wiki/MSYS) are currently supported for the
+OpenJDK build. One of the differences of these systems from standard Windows
+tools is the way they handle Windows path names, particularly path names which
+contain spaces, backslashes as path separators and possibly drive letters.
+Depending on the use case and the specifics of each environment these path
+problems can be solved by a combination of quoting whole paths, translating
+backslashes to forward slashes, escaping backslashes with additional
+backslashes and translating the path names to their ["8.3"
+version](http://en.wikipedia.org/wiki/8.3_filename).
+
+###### CYGWIN
+
+CYGWIN is an open source, Linux-like environment which tries to emulate a
+complete POSIX layer on Windows. It tries to be smart about path names and can
+usually handle all kinds of paths if they are correctly quoted or escaped
+although internally it maps drive letters `<drive>:` to a virtual directory
+`/cygdrive/<drive>`.
+
+You can always use the `cygpath` utility to map pathnames with spaces or the
+backslash character into the `C:/` style of pathname (called 'mixed'), e.g.
+`cygpath -s -m "<path>"`.
+
+Note that the use of CYGWIN creates a unique problem with regards to setting
+[`PATH`](#path). Normally on Windows the `PATH` variable contains directories
+separated with the ";" character (Solaris and Linux use ":"). With CYGWIN, it
+uses ":", but that means that paths like "C:/path" cannot be placed in the
+CYGWIN version of `PATH` and instead CYGWIN uses something like
+`/cygdrive/c/path` which CYGWIN understands, but only CYGWIN understands.
+
+The OpenJDK build requires CYGWIN version 1.7.16 or newer. Information about
+CYGWIN can be obtained from the CYGWIN website at
+[www.cygwin.com](http://www.cygwin.com).
+
+By default CYGWIN doesn't install all the tools required for building the
+OpenJDK. Along with the default installation, you need to install the following
+tools.
+
+ Binary Name Category Package Description
+ ------------- -------------- ---------- ------------------------------------------------------------
+ ar.exe Devel binutils The GNU assembler, linker and binary utilities
+ make.exe Devel make The GNU version of the 'make' utility built for CYGWIN
+ m4.exe Interpreters m4 GNU implementation of the traditional Unix macro processor
+ cpio.exe Utils cpio A program to manage archives of files
+ gawk.exe Utils awk Pattern-directed scanning and processing language
+ file.exe Utils file Determines file type using 'magic' numbers
+ zip.exe Archive zip Package and compress (archive) files
+ unzip.exe Archive unzip Extract compressed files in a ZIP archive
+ free.exe System procps Display amount of free and used memory in the system
+
+Note that the CYGWIN software can conflict with other non-CYGWIN software on
+your Windows system. CYGWIN provides a
+[FAQ](http://cygwin.com/faq/faq.using.html) for known issues and problems,
+of particular interest is the section on [BLODA (applications that interfere
+with CYGWIN)](http://cygwin.com/faq/faq.using.html#faq.using.bloda).
+
+###### MinGW/MSYS
+
+MinGW ("Minimalist GNU for Windows") is a collection of free Windows specific
+header files and import libraries combined with GNU toolsets that allow one to
+produce native Windows programs that do not rely on any 3rd-party C runtime
+DLLs. MSYS is a supplement to MinGW which allows building applications and
+programs which rely on traditional UNIX tools to be present. Among others this
+includes tools like `bash` and `make`. See
+[MinGW/MSYS](http://www.mingw.org/wiki/MSYS) for more information.
+
+Like Cygwin, MinGW/MSYS can handle different types of path formats. They are
+internally converted to paths with forward slashes and drive letters `<drive>:`
+replaced by a virtual directory `/<drive>`. Additionally, MSYS automatically
+detects binaries compiled for the MSYS environment and feeds them with the
+internal, Unix-style path names. If native Windows applications are called from
+within MSYS programs their path arguments are automatically converted back to
+Windows style path names with drive letters and backslashes as path separators.
+This may cause problems for Windows applications which use forward slashes as
+parameter separator (e.g. `cl /nologo /I`) because MSYS may wrongly [replace
+such parameters by drive
+letters](http://mingw.org/wiki/Posix_path_conversion).
+
+In addition to the tools which will be installed by default, you have to
+manually install the `msys-zip` and `msys-unzip` packages. This can be easily
+done with the MinGW command line installer:
+
+ mingw-get.exe install msys-zip
+ mingw-get.exe install msys-unzip
+
+##### Visual Studio 2013 Compilers
+
+The 32-bit and 64-bit OpenJDK Windows build requires Microsoft Visual Studio
+C++ 2013 (VS2013) Professional Edition or Express compiler. The compiler and
+other tools are expected to reside in the location defined by the variable
+`VS120COMNTOOLS` which is set by the Microsoft Visual Studio installer.
+
+Only the C++ part of VS2013 is needed. Try to let the installation go to the
+default install directory. Always reboot your system after installing VS2013.
+The system environment variable VS120COMNTOOLS should be set in your
+environment.
+
+Make sure that TMP and TEMP are also set in the environment and refer to
+Windows paths that exist, like `C:\temp`, not `/tmp`, not `/cygdrive/c/temp`,
+and not `C:/temp`. `C:\temp` is just an example, it is assumed that this area
+is private to the user, so by default after installs you should see a unique
+user path in these variables.
+
+#### Mac OS X
+
+Make sure you get the right XCode version.
+
+-------------------------------------------------------------------------------
+
+### Configure
+
+The basic invocation of the `configure` script looks like:
+
+> **`bash ./configure [options]`**
+
+This will create an output directory containing the "configuration" and setup
+an area for the build result. This directory typically looks like:
+
+> **`build/linux-x64-normal-server-release`**
+
+`configure` will try to figure out what system you are running on and where all
+necessary build components are. If you have all prerequisites for building
+installed, it should find everything. If it fails to detect any component
+automatically, it will exit and inform you about the problem. When this
+happens, read more below in [the `configure` options](#configureoptions).
+
+Some examples:
+
+> **Windows 32bit build with freetype specified:** \
+> `bash ./configure --with-freetype=/cygdrive/c/freetype-i586 --with-target-bits=32`
+
+> **Debug 64bit Build:** \
+> `bash ./configure --enable-debug --with-target-bits=64`
+
+#### Configure Options
+
+Complete details on all the OpenJDK `configure` options can be seen with:
+
+> **`bash ./configure --help=short`**
+
+Use `-help` to see all the `configure` options available. You can generate any
+number of different configurations, e.g. debug, release, 32, 64, etc.
+
+Some of the more commonly used `configure` options are:
+
+> **`--enable-debug`** \
+> set the debug level to fastdebug (this is a shorthand for
+> `--with-debug-level=fastdebug`)
+
+<a name="alsa"></a>
+
+> **`--with-alsa=`**_path_ \
+> select the location of the Advanced Linux Sound Architecture (ALSA)
+
+> Version 0.9.1 or newer of the ALSA files are required for building the
+ OpenJDK on Linux. These Linux files are usually available from an "alsa" of
+ "libasound" development package, and it's highly recommended that you try
+ and use the package provided by the particular version of Linux that you are
+ using.
+
+> **`--with-boot-jdk=`**_path_ \
+> select the [Bootstrap JDK](#bootjdk)
+
+> **`--with-boot-jdk-jvmargs=`**"_args_" \
+> provide the JVM options to be used to run the [Bootstrap JDK](#bootjdk)
+
+> **`--with-cacerts=`**_path_ \
+> select the path to the cacerts file.
+
+> See [Certificate Authority on
+ Wikipedia](http://en.wikipedia.org/wiki/Certificate_Authority) for a
+ better understanding of the Certificate Authority (CA). A certificates file
+ named "cacerts" represents a system-wide keystore with CA certificates. In
+ JDK and JRE binary bundles, the "cacerts" file contains root CA certificates
+ from several public CAs (e.g., VeriSign, Thawte, and Baltimore). The source
+ contain a cacerts file without CA root certificates. Formal JDK builders will
+ need to secure permission from each public CA and include the certificates
+ into their own custom cacerts file. Failure to provide a populated cacerts
+ file will result in verification errors of a certificate chain during
+ runtime. By default an empty cacerts file is provided and that should be fine
+ for most JDK developers.
+
+<a name="cups"></a>
+
+> **`--with-cups=`**_path_ \
+> select the CUPS install location
+
+> The Common UNIX Printing System (CUPS) Headers are required for building the
+ OpenJDK on Solaris and Linux. The Solaris header files can be obtained by
+ installing the package **print/cups**.
+
+> The CUPS header files can always be downloaded from
+ [www.cups.org](http://www.cups.org).
+
+> **`--with-cups-include=`**_path_ \
+> select the CUPS include directory location
+
+> **`--with-debug-level=`**_level_ \
+> select the debug information level of release, fastdebug, or slowdebug
+
+> **`--with-dev-kit=`**_path_ \
+> select location of the compiler install or developer install location
+
+<a name="freetype"></a>
+
+> **`--with-freetype=`**_path_ \
+> select the freetype files to use.
+
+> Expecting the freetype libraries under `lib/` and the headers under
+ `include/`.
+
+> Version 2.3 or newer of FreeType is required. On Unix systems required files
+ can be available as part of your distribution (while you still may need to
+ upgrade them). Note that you need development version of package that
+ includes both the FreeType library and header files.
+
+> You can always download latest FreeType version from the [FreeType
+ website](http://www.freetype.org). Building the freetype 2 libraries from
+ scratch is also possible, however on Windows refer to the [Windows FreeType
+ DLL build instructions](http://freetype.freedesktop.org/wiki/FreeType_DLL).
+
+> Note that by default FreeType is built with byte code hinting support
+ disabled due to licensing restrictions. In this case, text appearance and
+ metrics are expected to differ from Sun's official JDK build. See the
+ [SourceForge FreeType2 Home Page](http://freetype.sourceforge.net/freetype2)
+ for more information.
+
+> **`--with-import-hotspot=`**_path_ \
+> select the location to find hotspot binaries from a previous build to avoid
+ building hotspot
+
+> **`--with-target-bits=`**_arg_ \
+> select 32 or 64 bit build
+
+> **`--with-jvm-variants=`**_variants_ \
+> select the JVM variants to build from, comma separated list that can
+ include: server, client, kernel, zero and zeroshark
+
+> **`--with-memory-size=`**_size_ \
+> select the RAM size that GNU make will think this system has
+
+> **`--with-msvcr-dll=`**_path_ \
+> select the `msvcr100.dll` file to include in the Windows builds (C/C++
+ runtime library for Visual Studio).
+
+> This is usually picked up automatically from the redist directories of
+ Visual Studio 2013.
+
+> **`--with-num-cores=`**_cores_ \
+> select the number of cores to use (processor count or CPU count)
+
+<a name="xrender"></a>
+
+> **`--with-x=`**_path_ \
+> select the location of the X11 and xrender files.
+
+> The XRender Extension Headers are required for building the OpenJDK on
+ Solaris and Linux. The Linux header files are usually available from a
+ "Xrender" development package, it's recommended that you try and use the
+ package provided by the particular distribution of Linux that you are using.
+ The Solaris XRender header files is included with the other X11 header files
+ in the package **SFWxwinc** on new enough versions of Solaris and will be
+ installed in `/usr/X11/include/X11/extensions/Xrender.h` or
+ `/usr/openwin/share/include/X11/extensions/Xrender.h`
+
+-------------------------------------------------------------------------------
+
+### Make
+
+The basic invocation of the `make` utility looks like:
+
+> **`make all`**
+
+This will start the build to the output directory containing the
+"configuration" that was created by the `configure` script. Run `make help` for
+more information on the available targets.
+
+There are some of the make targets that are of general interest:
+
+> _empty_ \
+> build everything but no images
+
+> **`all`** \
+> build everything including images
+
+> **`all-conf`** \
+> build all configurations
+
+> **`images`** \
+> create complete j2sdk and j2re images
+
+> **`install`** \
+> install the generated images locally, typically in `/usr/local`
+
+> **`clean`** \
+> remove all files generated by make, but not those generated by `configure`
+
+> **`dist-clean`** \
+> remove all files generated by both and `configure` (basically killing the
+ configuration)
+
+> **`help`** \
+> give some help on using `make`, including some interesting make targets
+
+-------------------------------------------------------------------------------
+
+## Testing
+
+When the build is completed, you should see the generated binaries and
+associated files in the `j2sdk-image` directory in the output directory. In
+particular, the `build/*/images/j2sdk-image/bin` directory should contain
+executables for the OpenJDK tools and utilities for that configuration. The
+testing tool `jtreg` will be needed and can be found at: [the jtreg
+site](http://openjdk.java.net/jtreg/). The provided regression tests in the
+repositories can be run with the command:
+
+> **``cd test && make PRODUCT_HOME=`pwd`/../build/*/images/j2sdk-image all``**
+
+-------------------------------------------------------------------------------
+
+## Appendix A: Hints and Tips
+
+### FAQ
+
+**Q:** The `generated-configure.sh` file looks horrible! How are you going to
+edit it? \
+**A:** The `generated-configure.sh` file is generated (think "compiled") by the
+autoconf tools. The source code is in `configure.ac` and various .m4 files in
+common/autoconf, which are much more readable.
+
+**Q:** Why is the `generated-configure.sh` file checked in, if it is
+generated? \
+**A:** If it was not generated, every user would need to have the autoconf
+tools installed, and re-generate the `configure` file as the first step. Our
+goal is to minimize the work needed to be done by the user to start building
+OpenJDK, and to minimize the number of external dependencies required.
+
+**Q:** Do you require a specific version of autoconf for regenerating
+`generated-configure.sh`? \
+**A:** Yes, version 2.69 is required and should be easy enough to aquire on all
+supported operating systems. The reason for this is to avoid large spurious
+changes in `generated-configure.sh`.
+
+**Q:** How do you regenerate `generated-configure.sh` after making changes to
+the input files? \
+**A:** Regnerating `generated-configure.sh` should always be done using the
+script `common/autoconf/autogen.sh` to ensure that the correct files get
+updated. This script should also be run after mercurial tries to merge
+`generated-configure.sh` as a merge of the generated file is not guaranteed to
+be correct.
+
+**Q:** What are the files in `common/makefiles/support/*` for? They look like
+gibberish. \
+**A:** They are a somewhat ugly hack to compensate for command line length
+limitations on certain platforms (Windows, Solaris). Due to a combination of
+limitations in make and the shell, command lines containing too many files will
+not work properly. These helper files are part of an elaborate hack that will
+compress the command line in the makefile and then uncompress it safely. We're
+not proud of it, but it does fix the problem. If you have any better
+suggestions, we're all ears! :-)
+
+**Q:** I want to see the output of the commands that make runs, like in the old
+build. How do I do that? \
+**A:** You specify the `LOG` variable to make. There are several log levels:
+
+ * **`warn`** -- Default and very quiet.
+ * **`info`** -- Shows more progress information than warn.
+ * **`debug`** -- Echos all command lines and prints all macro calls for
+ compilation definitions.
+ * **`trace`** -- Echos all \$(shell) command lines as well.
+
+**Q:** When do I have to re-run `configure`? \
+**A:** Normally you will run `configure` only once for creating a
+configuration. You need to re-run configuration only if you want to change any
+configuration options, or if you pull down changes to the `configure` script.
+
+**Q:** I have added a new source file. Do I need to modify the makefiles? \
+**A:** Normally, no. If you want to create e.g. a new native library, you will
+need to modify the makefiles. But for normal file additions or removals, no
+changes are needed. There are certan exceptions for some native libraries where
+the source files are spread over many directories which also contain sources
+for other libraries. In these cases it was simply easier to create include
+lists rather than excludes.
+
+**Q:** When I run `configure --help`, I see many strange options, like
+`--dvidir`. What is this? \
+**A:** Configure provides a slew of options by default, to all projects that
+use autoconf. Most of them are not used in OpenJDK, so you can safely ignore
+them. To list only OpenJDK specific features, use `configure --help=short`
+instead.
+
+**Q:** `configure` provides OpenJDK-specific features such as
+`--with-builddeps-server` that are not described in this document. What about
+those? \
+**A:** Try them out if you like! But be aware that most of these are
+experimental features. Many of them don't do anything at all at the moment; the
+option is just a placeholder. Others depend on pieces of code or infrastructure
+that is currently not ready for prime time.
+
+**Q:** How will you make sure you don't break anything? \
+**A:** We have a script that compares the result of the new build system with
+the result of the old. For most part, we aim for (and achieve) byte-by-byte
+identical output. There are however technical issues with e.g. native binaries,
+which might differ in a byte-by-byte comparison, even when building twice with
+the old build system. For these, we compare relevant aspects (e.g. the symbol
+table and file size). Note that we still don't have 100% equivalence, but we're
+close.
+
+**Q:** I noticed this thing X in the build that looks very broken by design.
+Why don't you fix it? \
+**A:** Our goal is to produce a build output that is as close as technically
+possible to the old build output. If things were weird in the old build, they
+will be weird in the new build. Often, things were weird before due to
+obscurity, but in the new build system the weird stuff comes up to the surface.
+The plan is to attack these things at a later stage, after the new build system
+is established.
+
+**Q:** The code in the new build system is not that well-structured. Will you
+fix this? \
+**A:** Yes! The new build system has grown bit by bit as we converted the old
+system. When all of the old build system is converted, we can take a step back
+and clean up the structure of the new build system. Some of this we plan to do
+before replacing the old build system and some will need to wait until after.
+
+**Q:** Is anything able to use the results of the new build's default make
+target? \
+**A:** Yes, this is the minimal (or roughly minimal) set of compiled output
+needed for a developer to actually execute the newly built JDK. The idea is
+that in an incremental development fashion, when doing a normal make, you
+should only spend time recompiling what's changed (making it purely
+incremental) and only do the work that's needed to actually run and test your
+code. The packaging stuff that is part of the `images` target is not needed for
+a normal developer who wants to test his new code. Even if it's quite fast,
+it's still unnecessary. We're targeting sub-second incremental rebuilds! ;-)
+(Or, well, at least single-digit seconds...)
+
+**Q:** I usually set a specific environment variable when building, but I can't
+find the equivalent in the new build. What should I do? \
+**A:** It might very well be that we have neglected to add support for an
+option that was actually used from outside the build system. Email us and we
+will add support for it!
+
+### Build Performance Tips
+
+Building OpenJDK requires a lot of horsepower. Some of the build tools can be
+adjusted to utilize more or less of resources such as parallel threads and
+memory. The `configure` script analyzes your system and selects reasonable
+values for such options based on your hardware. If you encounter resource
+problems, such as out of memory conditions, you can modify the detected values
+with:
+
+ * **`--with-num-cores`** -- number of cores in the build system, e.g.
+ `--with-num-cores=8`
+ * **`--with-memory-size`** -- memory (in MB) available in the build system,
+ e.g. `--with-memory-size=1024`
+
+It might also be necessary to specify the JVM arguments passed to the Bootstrap
+JDK, using e.g. `--with-boot-jdk-jvmargs="-Xmx8G -enableassertions"`. Doing
+this will override the default JVM arguments passed to the Bootstrap JDK.
+
+One of the top goals of the new build system is to improve the build
+performance and decrease the time needed to build. This will soon also apply to
+the java compilation when the Smart Javac wrapper is fully supported.
+
+At the end of a successful execution of `configure`, you will get a performance
+summary, indicating how well the build will perform. Here you will also get
+performance hints. If you want to build fast, pay attention to those!
+
+#### Building with ccache
+
+The OpenJDK build supports building with ccache when using gcc or clang. Using
+ccache can radically speed up compilation of native code if you often rebuild
+the same sources. Your milage may vary however so we recommend evaluating it
+for yourself. To enable it, make sure it's on the path and configure with
+`--enable-ccache`.
+
+#### Building on local disk
+
+If you are using network shares, e.g. via NFS, for your source code, make sure
+the build directory is situated on local disk. The performance penalty is
+extremely high for building on a network share, close to unusable.
+
+#### Building only one JVM
+
+The old build builds multiple JVMs on 32-bit systems (client and server; and on
+Windows kernel as well). In the new build we have changed this default to only
+build server when it's available. This improves build times for those not
+interested in multiple JVMs. To mimic the old behavior on platforms that
+support it, use `--with-jvm-variants=client,server`.
+
+#### Selecting the number of cores to build on
+
+By default, `configure` will analyze your machine and run the make process in
+parallel with as many threads as you have cores. This behavior can be
+overridden, either "permanently" (on a `configure` basis) using
+`--with-num-cores=N` or for a single build only (on a make basis), using
+`make JOBS=N`.
+
+If you want to make a slower build just this time, to save some CPU power for
+other processes, you can run e.g. `make JOBS=2`. This will force the makefiles
+to only run 2 parallel processes, or even `make JOBS=1` which will disable
+parallelism.
+
+If you want to have it the other way round, namely having slow builds default
+and override with fast if you're impatient, you should call `configure` with
+`--with-num-cores=2`, making 2 the default. If you want to run with more cores,
+run `make JOBS=8`
+
+### Troubleshooting
+
+#### Solving build problems
+
+If the build fails (and it's not due to a compilation error in a source file
+you've changed), the first thing you should do is to re-run the build with more
+verbosity. Do this by adding `LOG=debug` to your make command line.
+
+The build log (with both stdout and stderr intermingled, basically the same as
+you see on your console) can be found as `build.log` in your build directory.
+
+You can ask for help on build problems with the new build system on either the
+[build-dev](http://mail.openjdk.java.net/mailman/listinfo/build-dev) or the
+[build-infra-dev](http://mail.openjdk.java.net/mailman/listinfo/build-infra-dev)
+mailing lists. Please include the relevant parts of the build log.
+
+A build can fail for any number of reasons. Most failures are a result of
+trying to build in an environment in which all the pre-build requirements have
+not been met. The first step in troubleshooting a build failure is to recheck
+that you have satisfied all the pre-build requirements for your platform.
+Scanning the `configure` log is a good first step, making sure that what it
+found makes sense for your system. Look for strange error messages or any
+difficulties that `configure` had in finding things.
+
+Some of the more common problems with builds are briefly described below, with
+suggestions for remedies.
+
+ * **Corrupted Bundles on Windows:** \
+ Some virus scanning software has been known to corrupt the downloading of
+ zip bundles. It may be necessary to disable the 'on access' or 'real time'
+ virus scanning features to prevent this corruption. This type of 'real time'
+ virus scanning can also slow down the build process significantly.
+ Temporarily disabling the feature, or excluding the build output directory
+ may be necessary to get correct and faster builds.
+
+ * **Slow Builds:** \
+ If your build machine seems to be overloaded from too many simultaneous C++
+ compiles, try setting the `JOBS=1` on the `make` command line. Then try
+ increasing the count slowly to an acceptable level for your system. Also:
+
+ Creating the javadocs can be very slow, if you are running javadoc, consider
+ skipping that step.
+
+ Faster CPUs, more RAM, and a faster DISK usually helps. The VM build tends
+ to be CPU intensive (many C++ compiles), and the rest of the JDK will often
+ be disk intensive.
+
+ Faster compiles are possible using a tool called
+ [ccache](http://ccache.samba.org/).
+
+ * **File time issues:** \
+ If you see warnings that refer to file time stamps, e.g.
+
+ > _Warning message:_ ` File 'xxx' has modification time in the future.` \
+ > _Warning message:_ ` Clock skew detected. Your build may be incomplete.`
+
+ These warnings can occur when the clock on the build machine is out of sync
+ with the timestamps on the source files. Other errors, apparently unrelated
+ but in fact caused by the clock skew, can occur along with the clock skew
+ warnings. These secondary errors may tend to obscure the fact that the true
+ root cause of the problem is an out-of-sync clock.
+
+ If you see these warnings, reset the clock on the build machine, run
+ "`gmake clobber`" or delete the directory containing the build output, and
+ restart the build from the beginning.
+
+ * **Error message: `Trouble writing out table to disk`** \
+ Increase the amount of swap space on your build machine. This could be
+ caused by overloading the system and it may be necessary to use:
+
+ > `make JOBS=1`
+
+ to reduce the load on the system.
+
+ * **Error Message: `libstdc++ not found`:** \
+ This is caused by a missing libstdc++.a library. This is installed as part
+ of a specific package (e.g. libstdc++.so.devel.386). By default some 64-bit
+ Linux versions (e.g. Fedora) only install the 64-bit version of the
+ libstdc++ package. Various parts of the JDK build require a static link of
+ the C++ runtime libraries to allow for maximum portability of the built
+ images.
+
+ * **Linux Error Message: `cannot restore segment prot after reloc`** \
+ This is probably an issue with SELinux (See [SELinux on
+ Wikipedia](http://en.wikipedia.org/wiki/SELinux)). Parts of the VM is built
+ without the `-fPIC` for performance reasons.
+
+ To completely disable SELinux:
+
+ 1. `$ su root`
+ 2. `# system-config-securitylevel`
+ 3. `In the window that appears, select the SELinux tab`
+ 4. `Disable SELinux`
+
+ Alternatively, instead of completely disabling it you could disable just
+ this one check.
+
+ 1. Select System->Administration->SELinux Management
+ 2. In the SELinux Management Tool which appears, select "Boolean" from the
+ menu on the left
+ 3. Expand the "Memory Protection" group
+ 4. Check the first item, labeled "Allow all unconfined executables to use
+ libraries requiring text relocation ..."
+
+ * **Windows Error Messages:** \
+ `*** fatal error - couldn't allocate heap, ... ` \
+ `rm fails with "Directory not empty"` \
+ `unzip fails with "cannot create ... Permission denied"` \
+ `unzip fails with "cannot create ... Error 50"`
+
+ The CYGWIN software can conflict with other non-CYGWIN software. See the
+ CYGWIN FAQ section on [BLODA (applications that interfere with
+ CYGWIN)](http://cygwin.com/faq/faq.using.html#faq.using.bloda).
+
+ * **Windows Error Message: `spawn failed`** \
+ Try rebooting the system, or there could be some kind of issue with the disk
+ or disk partition being used. Sometimes it comes with a "Permission Denied"
+ message.

+
+## Appendix B: GNU make
+
+The Makefiles in the OpenJDK are only valid when used with the GNU version of
+the utility command `make` (usually called `gmake` on Solaris). A few notes
+about using GNU make:
+
+ * You need GNU make version 3.81 or newer. On Windows 4.0 or newer is
+ recommended. If the GNU make utility on your systems is not of a suitable
+ version, see "[Building GNU make](#buildgmake)".
+ * Place the location of the GNU make binary in the `PATH`.
+ * **Solaris:** Do NOT use `/usr/bin/make` on Solaris. If your Solaris system
+ has the software from the Solaris Developer Companion CD installed, you
+ should try and use `/usr/bin/gmake` or `/usr/gnu/bin/make`.
+ * **Windows:** Make sure you start your build inside a bash shell.
+ * **Mac OS X:** The XCode "command line tools" must be installed on your Mac.
+
+Information on GNU make, and access to ftp download sites, are available on the
+[GNU make web site](http://www.gnu.org/software/make/make.html). The latest
+source to GNU make is available at
+[ftp.gnu.org/pub/gnu/make/](http://ftp.gnu.org/pub/gnu/make/).
+
+### Building GNU make
+
+First step is to get the GNU make 3.81 or newer source from
+[ftp.gnu.org/pub/gnu/make/](http://ftp.gnu.org/pub/gnu/make/). Building is a
+little different depending on the OS but is basically done with:
+
+ bash ./configure
+ make
+
+-------------------------------------------------------------------------------
+
+## Appendix C: Build Environments
+
+### Minimum Build Environments
+
+This file often describes specific requirements for what we call the "minimum
+build environments" (MBE) for this specific release of the JDK. What is listed
+below is what the Oracle Release Engineering Team will use to build the Oracle
+JDK product. Building with the MBE will hopefully generate the most compatible
+bits that install on, and run correctly on, the most variations of the same
+base OS and hardware architecture. In some cases, these represent what is often
+called the least common denominator, but each Operating System has different
+aspects to it.
+
+In all cases, the Bootstrap JDK version minimum is critical, we cannot
+guarantee builds will work with older Bootstrap JDK's. Also in all cases, more
+RAM and more processors is better, the minimums listed below are simply
+recommendations.
+
+With Solaris and Mac OS X, the version listed below is the oldest release we
+can guarantee builds and works, and the specific version of the compilers used
+could be critical.
+
+With Windows the critical aspect is the Visual Studio compiler used, which due
+to it's runtime, generally dictates what Windows systems can do the builds and
+where the resulting bits can be used.
+
+**NOTE: We expect a change here off these older Windows OS releases and to a
+'less older' one, probably Windows 2008R2 X64.**
+
+With Linux, it was just a matter of picking a stable distribution that is a
+good representative for Linux in general.
+
+It is understood that most developers will NOT be using these specific
+versions, and in fact creating these specific versions may be difficult due to
+the age of some of this software. It is expected that developers are more often
+using the more recent releases and distributions of these operating systems.
+
+Compilation problems with newer or different C/C++ compilers is a common
+problem. Similarly, compilation problems related to changes to the
+`/usr/include` or system header files is also a common problem with older,
+newer, or unreleased OS versions. Please report these types of problems as bugs
+so that they can be dealt with accordingly.
