32 This README file contains build instructions for the
33 <a href="http://openjdk.java.net" target="_blank">OpenJDK</a>.
34 Building the source code for the
35 OpenJDK
36 requires
37 a certain degree of technical expertise.

39 <blockquote style="background-color:white">
40 This document is specific to OpenJDK 6, which has some
41 very minor differences in the build requirements over
42 the OpenJDK 7 sources,
43 e.g. OpenJDK 6 requires access to Motif files.
44 Where there are differences they should stand out,
45 like this block of text does.

128 <h2><a name="hg">Use of Mercurial</a></h2>
129 <blockquote>
130 The OpenJDK sources are maintained with the revision control system
131 <a href="http://mercurial.selenic.com/wiki/Mercurial">Mercurial</a>.
132 If you are new to Mercurial, please see the
133 <a href="http://mercurial.selenic.com/wiki/BeginnersGuides">Beginner Guides</a>
134 or refer to the <a href="http://hgbook.red-bean.com/">Mercurial Book</a>.
135 The first few chapters of the book provide an excellent overview of
136 Mercurial, what it is and how it works.
137 <br>
138 For using Mercurial with the OpenJDK refer to the
139 <a href="http://openjdk.java.net/guide/repositories.html#installConfig">
140 Developer Guide: Installing and Configuring Mercurial</a>
141 section for more information.
142 The Forest Extension is not part of the Mercurial install,
143 and is optional,
144 but can be obtained with the following commands:
145 <blockquote>
146 <tt>
147 hg clone https://bitbucket.org/pmezard/hgforest-crew/overview/ <i>YourHgForest</i>
148 </tt>
149 </blockquote>
150 Once you have the file <tt>forest.py</tt>, you need to add these
151 lines to your <tt>${HOME}/.hgrc</tt> file:
152 <blockquote>
153 <tt>
154 [extensions]
155 <br>forest = <i>YourHgForest</i>/forest.py
156 </tt>
157 </blockquote>
158
159 <!-- ------------------------------------------------------ -->
160 <h3><a name="get_source">Getting the Source</a></h3>
161 <blockquote>
162 To get the entire set of OpenJDK Mercurial repositories
163 using the Forest Extension:
164 <blockquote>
165 <tt>
166 hg fclone http://hg.openjdk.java.net/jdk6/jdk6 <i>YourOpenJDK</i>
167 </tt>
168 </blockquote>
169 To get the entire set of OpenJDK Mercurial repositories
170 without using the Forest Extension:
171 <blockquote>
172 <tt>
173 hg clone http://hg.openjdk.java.net/jdk6/jdk6 <i>YourOpenJDK</i>
174 <br>cd <i>YourOpenJDK</i>
175 <br>sh ./get_source.sh
176 </tt>
177 </blockquote>
178 Once you have all the repositories, the
179 script <tt>make/scripts/hgforest.sh</tt>
180 can be used to repeat the same <tt>hg</tt>
181 command on every repository in the forest, e.g.
182 <blockquote>
183 <tt>
184 cd <i>YourOpenJDK</i>
185 <br>sh ./make/scripts/hgforest.sh pull -u
186 </tt>
187 </blockquote>
188 You may find this script <tt>make/scripts/hgforest.sh</tt> faster
189 than the <tt>hg</tt> forest commands provided by the
190 Forest Extension.

199 This file often describes specific requirements for what we call the
200 "minimum build environments" (MBE) for this
201 specific release of the JDK,
202 Building with the MBE will generate the most compatible
203 bits that install on, and run correctly on, the most variations
204 of the same base OS and hardware architecture.
205 These usually represent what is often called the
206 least common denominator platforms.
207 It is understood that most developers will NOT be using these
208 specific platforms, and in fact creating these specific platforms
209 may be difficult due to the age of some of this software.

276 These same sources do indeed build on many more systems than the
277 above older generation systems, again the above is just a minimum.
278 <p>
279 Compilation problems with newer or different C/C++ compilers is a
280 common problem.
281 Similarly, compilation problems related to changes to the
282 <tt>/usr/include</tt> or system header files is also a
283 common problem with newer or unreleased OS versions.
284 Please report these types of problems as bugs so that they

555 <a href="http://jaxp.java.net/">JAXP</a> and
556 <a href="http://jax-ws.java.net/">JAX-WS</a> home pages.
557 The OpenJDK project does need access to these sources to build
558 a complete JDK image because JAXP and JAX-WS are part of the JDK.
559 The current process for delivery of the JAXP and JAX-WS sources
560 involves so called "source drop bundles" downloaded from a public
561 website.
562 There are many reasons for this current mechanism, and it is

564 It is possible this process could change in the future.

608 will attempt to locate these zip bundles from the directory
609 in the environment variable
610 <tt><a href="#ALT_DROPS_DIR">ALT_DROPS_DIR</a></tt>.
611 The checksums protect from getting the wrong, corrupted, or

618 <b>NOTE:</b> The default Makefile and ant script behavior
619 is to NOT download these bundles from the public http site.
620 In general, doing downloads
621 during the build process is not advised, it creates too much
622 unpredictability in the build process.
623 However, you can use <tt>make ALLOW_DOWNLOADS=true</tt> to
624 tell the ant script that the download of the zip bundle is
625 acceptable.
626 </p>
627 <p>
628 The recommended procedure for keeping a cache of these

631 <tt><a href="#ALT_DROPS_DIR">ALT_DROPS_DIR</a></tt> to refer
632 to that directory.
633 These drop bundles do change occasionally, so the newer

643 Building the OpenJDK
644 is done with a <a href="#gmake">GNU <tt>make</tt></a> command line
645 and various
646 environment or make variable settings that direct the make rules
647 to where various components have been installed.
648 Where possible the makefiles will attempt to located the various
649 components in the default locations or any component specific
650 variable settings.
651 When the normal defaults fail or components cannot be found,
652 the various
653 <tt>ALT_*</tt> variables (alternates)
654 can be used to help the makefiles locate components.
655 <p>
656 Refer to the bash/sh/ksh setup file
657 <tt>jdk/make/jdk_generic_profile.sh</tt>
658 if you need help in setting up your environment variables.

679 The Makefiles in the OpenJDK are only valid when used with the
680 GNU version of the utility command <tt>make</tt>
681 (<tt><i>gmake</i></tt>).
682 A few notes about using GNU make:
683 <ul>
684 <li>
685 You need GNU make version 3.81 or newer.
686 </li>
687 <li>
688 Place the location of the GNU make binary in the <tt>PATH</tt>.
689 </li>
690 <li>
691 <strong>Linux:</strong>
692 The <tt>/usr/bin/make</tt> should be 3.81 or newer
693 and should work fine for you.
694 If this version is not 3.81 or newer,
695 see the <a href="#buildgmake">"Building GNU make"</a> section.
696 </li>
697 <li>
698 <strong>Solaris:</strong>
699 Do NOT use <tt>/usr/bin/make</tt> on Solaris.
700 If your Solaris system has the software
701 from the Solaris Companion CD installed,
702 you should try and use <tt>gmake</tt>
703 which will be located in either the <tt>/opt/sfw/bin</tt> or
704 <tt>/usr/sfw/bin</tt> directory.
705 In more recent versions of Solaris GNU make might be found
706 at <tt>/usr/bin/gmake</tt>.<br>
707 <b>NOTE:</b> It is very likely that this <tt>gmake</tt>
708 could be 3.80, you need 3.81, in which case,
709 see the <a href="#buildgmake">"Building GNU make"</a> section.
710 </li>
711 <li>
712 <strong>Windows:</strong>
713 Make sure you start your build inside a bash/sh/ksh shell
714 and are using a <tt>make.exe</tt> utility built for that

716 as a <tt>make.exe</tt> built for something like
717 <a href="http://www.mkssoftware.com/">MKS</a>).
718 <br>
719 <b>WARNING:</b> Watch out on some make 3.81 versions, it may
720 not work due to a lack of support for MS-DOS drive letter paths
721 like <tt>C:/</tt> or <tt>C:\</tt>.

727 <br>
728 It's hoped that when make 3.82 starts shipping in a future cygwin
729 release that this MS-DOS path issue will be fixed.

731 It may be possible to download the version at
732 <a href="http://www.cmake.org/files/cygwin/make.exe">

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

1076 http://en.wikipedia.org/wiki/Certificate_Authority</a>
1077 for a better understanding of the Certificate Authority (CA).
1078 A certificates file named "cacerts"
1079 represents a system-wide keystore with CA certificates.
1080 In JDK and JRE
1081 binary bundles, the "cacerts" file contains root CA certificates from
1082 several public CAs (e.g., VeriSign, Thawte, and Baltimore).
1083 The source contain a cacerts file
1084 without CA root certificates.
1085 Formal JDK builders will need to secure
1086 permission from each public CA and include the certificates into their
1087 own custom cacerts file.
1088 Failure to provide a populated cacerts file
1089 will result in verification errors of a certificate chain during runtime.
1090 The variable
1091 <tt><a href="#ALT_CACERTS_FILE">ALT_CACERTS_FILE</a></tt>
1092 can be used to override the default location of the
1093 cacerts file that will get placed in your build.
1094 By default an empty cacerts file is provided and that should be
1095 fine for most JDK developers.

1787 <h2><a name="troubleshooting">Troubleshooting</a></h2>
1788 <blockquote>
1789 A build can fail for any number of reasons.
1790 Most failures
1791 are a result of trying to build in an environment in which all the
1792 pre-build requirements have not been met.
1793 The first step in
1794 troubleshooting a build failure is to recheck that you have satisfied
1795 all the pre-build requirements for your platform.
1796 Look for the check list of the platform you are building on in the
1797 <a href="#contents">Table of Contents</a>.
1798 <p>
1799 You can validate your build environment by using the <tt>sanity</tt>
1800 target.
1801 Any errors listed
1802 will stop the build from starting, and any warnings may result in
1803 a flawed product build.
1804 We strongly encourage you to evaluate every
1805 sanity check warning and fix it if required, before you proceed
1806 further with your build.
1807 <p>
1808 Some of the more common problems with builds are briefly described
1809 below, with suggestions for remedies.
1810 <ul>
1811 <li>
1812 <b>Corrupted Bundles on Windows:</b>
1813 <blockquote>
1814 Some virus scanning software has been known to corrupt the
1815 downloading of zip bundles.
1816 It may be necessary to disable the 'on access' or 'real time'
1817 virus scanning features to prevent this corruption.
1818 This type of "real time" virus scanning can also slow down the
1819 build process significantly.
1820 Temporarily disabling the feature, or excluding the build
1821 output directory may be necessary to get correct and faster builds.
1822 </blockquote>
1823 </li>
1824 <li>
1825 <b>Slow Builds:</b>
1826 <blockquote>
1827 If your build machine seems to be overloaded from too many
1828 simultaneous C++ compiles, try setting the <tt>HOTSPOT_BUILD_JOBS</tt>
1829 variable to <tt>1</tt> (if you're using a multiple CPU
1830 machine, setting it to more than the the number of CPUs is probably
1831 not a good idea).
1832 <p>
1833 Creating the javadocs can be very slow, if you are running
1834 javadoc, consider skipping that step.
1835 <p>
1836 Faster hardware and more RAM always helps too.
1837 The VM build tends to be CPU intensive (many C++ compiles),
1838 and the rest of the JDK will often be disk intensive.
1839 <p>
1840 Faster compiles are possible using a tool called
1841 <a href="http://ccache.samba.org/" target="_blank">ccache</a>.
1842 </blockquote>
1843 </li>
1844 <li>
1845 <b>File time issues:</b>
1846 <blockquote>
1847 If you see warnings that refer to file time stamps, e.g.
1848 <blockquote>
1849 <i>Warning message:</i><tt> File `xxx' has modification time in
1850 the future.</tt>
1851 <br>
1852 <i>Warning message:</i> <tt> Clock skew detected. Your build may
1853 be incomplete.</tt>
1854 </blockquote>
1855 These warnings can occur when the clock on the build machine is out of
1856 sync with the timestamps on the source files. Other errors, apparently
1857 unrelated but in fact caused by the clock skew, can occur along with
1858 the clock skew warnings. These secondary errors may tend to obscure the
1859 fact that the true root cause of the problem is an out-of-sync clock.
1860 For example, an out-of-sync clock has been known to cause an old
1861 version of javac to be used to compile some files, resulting in errors
1862 when the pre-1.4 compiler ran across the new <tt>assert</tt> keyword
1863 in the 1.4 source code.
1864 <p>
1865 If you see these warnings, reset the clock on the build
1866 machine, run "<tt><i>gmake</i> clobber</tt>" or delete the directory
1867 containing the build output, and restart the build from the beginning.

1872 <blockquote>
1873 Increase the amount of swap space on your build machine.
1874 </blockquote>
1875 </li>
1876 <li>
1877 <b>Error Message: <tt>libstdc++ not found:</tt></b>
1878 <blockquote>
1879 This is caused by a missing libstdc++.a library.
1880 This is installed as part of a specific package
1881 (e.g. libstdc++.so.devel.386).
1882 By default some 64bit Linux versions (e.g. Fedora)
1883 only install the 64bit version of the libstdc++ package.
1884 Various parts of the JDK build require a static
1885 link of the C++ runtime libraries to allow for maximum
1886 portability of the built images.
