+
+<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>
- <h3><a name="get_source">Getting the Source</a></h3>
- <blockquote>
- To get the entire set of OpenJDK Mercurial repositories
- use the script <code>get_source.sh</code> located in the
- root repository:
- <blockquote>
- <code>
- hg clone http://hg.openjdk.java.net/jdk9/jdk9
- <i>YourOpenJDK</i>
- <br>
- cd <i>YourOpenJDK</i>
- <br>
- bash ./get_source.sh
- </code>
- </blockquote>
- 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.
- <blockquote>
- <code>
- cd <i>YourOpenJDK</i>
- <br>
- bash ./make/scripts/hgforest.sh status
- </code>

+<pre><code> hg clone http://hg.openjdk.java.net/jdk9/jdk9 YourOpenJDK

+
+<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>

+<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>
- </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>
+

+
+<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>
- 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-unzip</code> packages.
- This can be easily done with the MinGW command line installer:

+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>

+<h3>FAQ</h3>
- <p>
- <b>Q:</b>
- How will you make sure you don't break anything?
- <br>
- <b>A:</b>
- 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> 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>
- <b>Q:</b>
- I noticed this thing X in the build that looks very broken by design.
- Why don't you fix it?
- <br>
- <b>A:</b>
- 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> 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>
- <b>Q:</b>
- The code in the new build system is not that well-structured.
- Will you fix this?
- <br>
- <b>A:</b>
- 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> 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

- <p>
- <b>Q:</b>
- Is anything able to use the results of the new build's default make target?
- <br>
- <b>A:</b>
- 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...)

+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>
- <b>Q:</b>
- 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>
- <b>A:</b>
- 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>
+<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>

- <h3><a name="performance">Build Performance Tips</a></h3>
- <blockquote>
+<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

+<li><strong><code>trace</code></strong> -- Echos all $(shell) command lines as well.</li>
+</ul>
- <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>
+<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>
- <ul>
- <li>
- <b><code>--with-num-cores</code></b>
- —
- number of cores in the build system,
- e.g. <code>--with-num-cores=8</code>
- </li>
- <li>
- <b><code>--with-memory-size</code></b>
- — memory (in MB) available in the build system,
- e.g. <code>--with-memory-size=1024</code>
- </li>
- </ul>
+<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>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><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>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><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>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><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>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><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>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>
-
- </blockquote>
+<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>
- <h3><a name="troubleshooting">Troubleshooting</a></h3>
- <blockquote>
+<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! ;-)

+<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>gmake</code> which will be located in either the <code>/usr/bin</code>,
+<code>/opt/sfw/bin</code> or <code>/usr/sfw/bin</code> directory.</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
