-
-<blockquote>
- <p>
- This file often describes specific requirements for what we call the
- "minimum build environments" (MBE) for the JDK.
- Building with the MBE will generate the most compatible
- bits that install on, and run correctly on, the most variations
- of the same base OS and hardware architecture.
- These usually represent what is often called the
- least common denominator platforms.
- It is understood that most developers will NOT be using these
- specific platforms, and in fact creating these specific platforms
- may be difficult due to the age of some of this software.
- <p>
-
- <p>
- The minimum OS and C/C++ compiler versions needed for building the
- OpenJDK:

-<h2><a name="building">Build Information</a></h2>
-
-<blockquote>
- <p>
- Building the
- OpenJDK
- is done with a <tt><i>gmake</i></tt>
- command line and various
- environment or make variable settings that direct the make rules
- to where various components have been installed.
- Where possible the makefiles will attempt to located the various
- components in the default locations or any component specific
- variable settings.
- When the normal defaults fail or components cannot be found,
- the various
- <tt>ALT_*</tt> variables (alternates)
- can be used to help the makefiles locate components.
- <p>
- Refer to the bash/sh/ksh setup file
- <tt>jdk/make/jdk_generic_profile.sh</tt>
- if you need help in setting up your environment variables.
- A build could be as simple as:
- <blockquote>
- <pre><tt>
- bash
- . jdk/make/jdk_generic_profile.sh
- <i>gmake</i> sanity && <i>gmake</i>
- </tt></pre>
- </blockquote>
- <p>
- Of course ksh or sh would work too.
- But some customization will probably be necessary.
- The <tt>sanity</tt> rule will make some basic checks on build
- dependencies and generate appropriate warning messages
- regarding missing, out of date, or newer than expected components
- found on your system.

- <p>
- The Makefiles in the
- OpenJDK
- are only valid when used with the
- GNU version of the utility command <tt>make</tt>
- (<tt><i>gmake</i></tt>).
- A few notes about using GNU make:
- <ul>
- <li>
- In general, you need GNU make version 3.78.1 or newer.
- </li>
- <li>
- Place the location of the GNU make binary in the <tt>PATH</tt>.
- </li>
- <li>
- <strong>Linux:</strong>
- The <tt>/usr/bin/make</tt> command should work fine for you.
- </li>
- <li>
- <strong>Solaris:</strong>
- Do NOT use <tt>/usr/bin/make</tt> on Solaris.
- If your Solaris system has the software
- from the Solaris Companion CD installed,
- you should use <tt>gmake</tt>
- which will be located in either the <tt>/opt/sfw/bin</tt> or
- <tt>/usr/sfw/bin</tt> directory.
- </li>
- <li>
- <strong>Windows:</strong>
- Make sure you start your build inside a bash/sh/ksh shell.
- <br>
- <b>WARNING:</b> Watch out for make version 3.81, it may
- not work due to a lack of support for drive letter paths
- like <tt>C:/</tt>. Use a 3.80 version, or find a newer
- version that has this problem fixed.
- </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">

-<h4><a name="paths">Windows Paths</a></h4>
-
-<blockquote>
- <p>
- <strong>Windows:</strong>
- Note that GNU make is a historic utility and is based very
- heavily on shell scripting, so it does not tolerate the Windows habit
- of having spaces in pathnames or the use of the <tt>\</tt>characters in pathnames.
- Luckily on most Windows systems, you can use <tt>/</tt>instead of \, and
- there is always a 'short' pathname without spaces for any path that
- contains spaces.
- Unfortunately, this short pathname can be somewhat dynamic and the
- formula is difficult to explain.
- You can use <tt>cygpath</tt> utility to map pathnames with spaces
- or the <tt>\</tt>character into the <tt>C:/</tt> style of pathname
- (called 'mixed'), e.g.
- <tt>cygpath -s -m "<i>path</i>"</tt>.
- <p>
- The makefiles will try to translate any pathnames supplied
- to it into the <tt>C:/</tt> style automatically.
- <p>
- Note that use of CYGWIN creates a unique problem with regards to
- setting <a href="#path"><tt>PATH</tt></a>. Normally on Windows
- the <tt>PATH</tt> variable contains directories
- separated with the ";" character (Solaris and Linux uses ":").
- With CYGWIN, it uses ":", but that means that paths like "C:/path"
- cannot be placed in the CYGWIN version of <tt>PATH</tt> and
- instead CYGWIN uses something like <tt>/cygdrive/c/path</tt>
- which CYGWIN understands, but only CYGWIN understands.
- So be careful with paths on Windows.

- Some of these are specific to a platform, some even specific to

- Each dependency will have a set of ALT variables that can be set

- All

- The JDK 6 binaries can be downloaded from Sun's
- <a href="http://java.sun.com/javase/1.6.0/download.html">JDK 6 download site</a>.
- For build performance reasons
- is very important that this bootstrap JDK be made available on the
- local disk of the machine doing the build.
- You should always set
- <tt><a href="#ALT_BOOTDIR">ALT_BOOTDIR</a></tt>
- to point to the location of
- the bootstrap JDK installation, this is the directory pathname
- that contains a <tt>bin, lib, and include</tt>
- It's also a good idea to also place its <tt>bin</tt> directory
- in the <tt>PATH</tt> environment variable, although it's
- not required.
- <p>
- <strong>Solaris:</strong>
- Some pre-installed JDK images may be available to you in the
- directory <tt>/usr/jdk/instances</tt>.
- If you don't set
- <tt><a href="#ALT_BOOTDIR">ALT_BOOTDIR</a></tt>
- the makefiles will look in that location for a JDK it can use.

- <blockquote>
- <p>
- Not all of the source code that makes up the JDK is available
- under an open-source license.
- In order to build an OpenJDK binary from source code,
- you must first download and install the appropriate
- binary plug bundles from the OpenJDK Download area.
- During the OpenJDK build process these "binary plugs"
- for the encumbered components will be copied into your
- resulting OpenJDK binary build image.
- These binary plug files are only for the purpose of
- building an OpenJDK binary.
- Download the Binary Plugs by selecting the <b>Downloads</b>

- <a href="http://openjdk.java.net/">the OpenJDK site</a>,

- <p>
- See <a href="http://en.wikipedia.org/wiki/CAcert">
- www.wikipedia.org/wiki/CAcert</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.
- The variable
- <tt><a href="#ALT_CACERTS_FILE">ALT_CACERTS_FILE</a></tt>
- can be used to override the default location of the
- cacerts file that will get placed in your build.
- By default an empty cacerts file is provided and that should be
- fine for most JDK developers.

-<h2><a name="troubleshooting">Troubleshooting</a></h2>
-
-<blockquote>
- <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.
- Look for the check list of the platform you are building on in the
- <a href="#contents">Table of Contents</a>.
-
- <p>
- You can validate your build environment by using the <tt>sanity</tt>
- target.
- Any errors listed
- will stop the build from starting, and any warnings may result in
- a flawed product build.
- We strongly encourage you to evaluate every
- sanity check warning and fix it if required, before you proceed
- further with your build.
-
- <p>
- Some of the more common problems with builds are briefly described
- below, with suggestions for remedies.
-
- <ul>
- <li>
- <b>Slow Builds:</b>
- <blockquote>
- <p>
- If your build machine seems to be overloaded from too many
- simultaneous C++ compiles, try setting the <tt>HOTSPOT_BUILD_JOBS</tt>
- variable to <tt>1</tt> (if you're using a multiple CPU
- machine, setting it to more than the the number of CPUs is probably
- not a good idea).
- <p>
- Creating the javadocs can be very slow, if you are running
- javadoc, consider skipping that step.
- <p>
- Faster hardware and more RAM always helps too.
- The VM build tends to be CPU intensive (many C++ compiles),
- and the rest of the JDK will often be disk intensive.
- <p>
- Faster compiles are possible using a tool called
- <a href="http://ccache.samba.org/">ccache</a>.
- </blockquote>
- </li>
- <li>
- <b>File time issues:</b>
- <blockquote>
- <p>
- If you see warnings that refer to file time stamps, e.g.
- <blockquote>
- <i>Warning message:</i><tt> File `xxx' has modification time in
- the future.</tt>
- <br>
- <i>Warning message:</i> <tt> Clock skew detected. Your build may
- be incomplete.</tt>
- </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.
- For example, an out-of-sync clock has been known to cause an old
- version of javac to be used to compile some files, resulting in errors
- when the pre-1.4 compiler ran across the new <tt>assert</tt> keyword
- in the 1.4 source code.
- <p>
- If you see these warnings, reset the clock on the build
- machine, run "<tt><i>gmake</i> clobber</tt>" or delete the directory
- containing the build output, and restart the build from the beginning.
- </blockquote>
- </li>
- <li>
- <b>Error message: <tt>Trouble writing out table to disk</tt></b>
- <blockquote>
- <p>
- Increase the amount of swap space on your build machine.
- </blockquote>
- </li>
- <li>
- <b>Error Message: <tt>libstdc++ not found:</tt></b>
- <blockquote>
- This is caused by a missing libstdc++.a library.
- This is installed as part of a specific package
