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,

119 <blockquote>
120 This file often describes specific requirements for what we call the
121 "minimum build environments" (MBE) for this
122 specific release of the JDK,
123 Building with the MBE will generate the most compatible
124 bits that install on, and run correctly on, the most variations
125 of the same base OS and hardware architecture.
126 These usually represent what is often called the
127 least common denominator platforms.
128 It is understood that most developers will NOT be using these
129 specific platforms, and in fact creating these specific platforms
130 may be difficult due to the age of some of this software.

207 These same sources do indeed build on many more systems than the
208 above older generation systems, again the above is just a minimum.
209 <p>
210 Compilation problems with newer or different C/C++ compilers is a
211 common problem.
212 Similarly, compilation problems related to changes to the
213 <tt>/usr/include</tt> or system header files is also a
214 common problem with newer or unreleased OS versions.
215 Please report these types of problems as bugs so that they
216 can be dealt with accordingly.

483 Building the OpenJDK
484 is done with a <tt><i>gmake</i></tt>
485 command line and various
486 environment or make variable settings that direct the make rules
487 to where various components have been installed.
488 Where possible the makefiles will attempt to located the various
489 components in the default locations or any component specific
490 variable settings.
491 When the normal defaults fail or components cannot be found,
492 the various
493 <tt>ALT_*</tt> variables (alternates)
494 can be used to help the makefiles locate components.
495 <p>
496 Refer to the bash/sh/ksh setup file
497 <tt>jdk/make/jdk_generic_profile.sh</tt>
498 if you need help in setting up your environment variables.
499 A build could be as simple as:
500 <blockquote>
501 <pre><tt>
502 bash
503 . jdk/make/jdk_generic_profile.sh
504 <i>gmake</i> sanity &amp;&amp; <i>gmake</i>

506 </blockquote>
507 <p>
508 Of course ksh or sh would work too.
509 But some customization will probably be necessary.
510 The <tt>sanity</tt> rule will make some basic checks on build
511 dependencies and generate appropriate warning messages

519 The Makefiles in the OpenJDK are only valid when used with the
520 GNU version of the utility command <tt>make</tt>
521 (<tt><i>gmake</i></tt>).
522 A few notes about using GNU make:
523 <ul>
524 <li>
525 In general, you need GNU make version 3.78.1 or newer.
526 </li>
527 <li>
528 Place the location of the GNU make binary in the <tt>PATH</tt>.

531 <strong>Linux:</strong>
532 The <tt>/usr/bin/make</tt> command should work fine for you.
533 </li>
534 <li>
535 <strong>Solaris:</strong>
536 Do NOT use <tt>/usr/bin/make</tt> on Solaris.
537 If your Solaris system has the software
538 from the Solaris Companion CD installed,
539 you should use <tt>gmake</tt>
540 which will be located in either the <tt>/opt/sfw/bin</tt> or
541 <tt>/usr/sfw/bin</tt> directory.
542 </li>
543 <li>
544 <strong>Windows:</strong>
545 Make sure you start your build inside a bash/sh/ksh shell
546 and are using a <tt>make.exe</tt> utility built for that
547 environment (a cygwin <tt>make.exe</tt> is not the same
548 as a <tt>make.exe</tt> built for something like

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

1065 OpenJDK 6.
1066 <p>
1067 <strong>Solaris:</strong>
1068 Normally these files can be found on Solaris systems
1069 at /usr/include/Xm, so on Solaris systems no further downloads
1070 should be needed.
1071 <p>
1072 <strong>Linux:</strong>
1073 On Linux, your particular Linux distribution may provide a
1074 "motif" development package you can install. If this package
1075 installs the files into /usr/include/Xm, no further action should
1076 be needed.
1077 An acceptable version of these Motif header files are
1078 available in the source bundle
1079 <a href="http://www.openbsd.org/3.9_packages/hppa/openmotif-2.1.30.5p1.tgz-long.html">
1080 openmotif-2.1.30.5p1.tgz</a>
1081 from
1082 <a href="http://www.openbsd.org/">www.openbsd.org</a>.
1083 You would need to install the package and set the environment variable
1084 <tt><a href="#ALT_MOTIF_DIR">ALT_MOTIF_DIR</a></tt>
1085 to refer to the top of this installation.

1109 <blockquote>
1110 <strong>Linux only:</strong>
1111 Version 0.9.1 or newer of the ALSA files are
1112 required for building the OpenJDK on Linux.
1113 These Linux files are usually available from an "alsa"
1114 of "libasound"
1115 development package, it's highly recommended that you try and use
1116 the package provided by the particular version of Linux that
1117 you are using.
1118 The makefiles will check this emit a sanity error if it is
1119 missing or the wrong version.
1120 <p>
1121 In particular, older Linux systems will likely not have the
1122 right version of ALSA installed, for example
1123 Redhat AS 2.1 U2 and SuSE 8.1 do not include a sufficiently
1124 recent ALSA distribution.
1125 On rpm-based systems, you can see if ALSA is installed by
1126 running this command:
1127 <pre>
1128 <tt>rpm -qa | grep alsa</tt>
1129 </pre>
1130 Both <tt>alsa</tt> and <tt>alsa-devel</tt> packages are needed.
1131 <p>
1132 If your distribution does not come with ALSA, and you can't
1133 find ALSA packages built for your particular system,
1134 you can try to install the pre-built ALSA rpm packages from
1135 <a href="http://www.freshrpms.net/" target="_blank">
1136 <tt>www.freshrpms.net</tt></a>.
1137 Note that installing a newer ALSA could
1138 break sound output if an older version of ALSA was previously
1139 installed on the system, but it will enable JDK compilation.
1140 <blockquote>
1141 Installation: execute as root<br>
1142 [i586]: <code>rpm -Uv --force alsa-lib-devel-0.9.1-rh61.i386.rpm</code><br>

1152 As a last resort you can go to the
1153 <a href="http://www.alsa-project.org" target="_blank">
1154 Advanced Linux Sound Architecture Site</a> and build it from
1155 source.
1156 <blockquote>
1157 Download driver and library
1158 source tarballs from
1159 <a href="http://www.alsa-project.org" target="_blank">ALSA's homepage</a>.

1174 </pre>
1175 Should one of the above steps fail, refer to the documentation on
1176 ALSA's home page.
1177 </blockquote>
1178 Note that this is a minimum install that enables
1179 building the JDK platform. To actually use ALSA sound drivers, more
1180 steps are necessary as outlined in the documentation on ALSA's homepage.
1181 <p>
1182 ALSA can be uninstalled by executing <tt>make uninstall</tt> first in
1183 the <tt>alsa-lib-0.9.1</tt> directory and then in
1184 <tt>alsa-driver-0.9.1</tt>.

1186 There are no ALT* variables to change the assumed locations of ALSA,
1187 the makefiles will expect to find the ALSA include files and library at:
1188 <tt>/usr/include/alsa</tt> and <tt>/usr/lib/libasound.so</tt>.

1643 <h2><a name="troubleshooting">Troubleshooting</a></h2>
1644 <blockquote>
1645 A build can fail for any number of reasons.
1646 Most failures
1647 are a result of trying to build in an environment in which all the
1648 pre-build requirements have not been met.
1649 The first step in
1650 troubleshooting a build failure is to recheck that you have satisfied
1651 all the pre-build requirements for your platform.
1652 Look for the check list of the platform you are building on in the
1653 <a href="#contents">Table of Contents</a>.
1654 <p>
1655 You can validate your build environment by using the <tt>sanity</tt>
1656 target.
1657 Any errors listed
1658 will stop the build from starting, and any warnings may result in
1659 a flawed product build.
1660 We strongly encourage you to evaluate every
1661 sanity check warning and fix it if required, before you proceed
1662 further with your build.
1663 <p>
1664 Some of the more common problems with builds are briefly described
1665 below, with suggestions for remedies.
1666 <ul>
1667 <li>
1668 <b>Slow Builds:</b>
1669 <blockquote>
1670 If your build machine seems to be overloaded from too many
1671 simultaneous C++ compiles, try setting the <tt>HOTSPOT_BUILD_JOBS</tt>
1672 variable to <tt>1</tt> (if you're using a multiple CPU
1673 machine, setting it to more than the the number of CPUs is probably
1674 not a good idea).
1675 <p>
1676 Creating the javadocs can be very slow, if you are running
1677 javadoc, consider skipping that step.
1678 <p>
1679 Faster hardware and more RAM always helps too.
1680 The VM build tends to be CPU intensive (many C++ compiles),
1681 and the rest of the JDK will often be disk intensive.
1682 <p>
1683 Faster compiles are possible using a tool called
1684 <a href="http://ccache.samba.org/" target="_blank">ccache</a>.
1685 </blockquote>
1686 </li>
1687 <li>
1688 <b>File time issues:</b>
1689 <blockquote>
1690 If you see warnings that refer to file time stamps, e.g.
1691 <blockquote>
1692 <i>Warning message:</i><tt> File `xxx' has modification time in
1693 the future.</tt>
1694 <br>
1695 <i>Warning message:</i> <tt> Clock skew detected. Your build may
1696 be incomplete.</tt>
1697 </blockquote>
1698 These warnings can occur when the clock on the build machine is out of
1699 sync with the timestamps on the source files. Other errors, apparently
1700 unrelated but in fact caused by the clock skew, can occur along with
1701 the clock skew warnings. These secondary errors may tend to obscure the
1702 fact that the true root cause of the problem is an out-of-sync clock.
1703 For example, an out-of-sync clock has been known to cause an old
1704 version of javac to be used to compile some files, resulting in errors
1705 when the pre-1.4 compiler ran across the new <tt>assert</tt> keyword
1706 in the 1.4 source code.
1707 <p>
1708 If you see these warnings, reset the clock on the build
1709 machine, run "<tt><i>gmake</i> clobber</tt>" or delete the directory
1710 containing the build output, and restart the build from the beginning.

1713 <li>
1714 <b>Error message: <tt>Trouble writing out table to disk</tt></b>
1715 <blockquote>
1716 Increase the amount of swap space on your build machine.
1717 </blockquote>
1718 </li>
1719 <li>
1720 <b>Error Message: <tt>libstdc++ not found:</tt></b>
1721 <blockquote>
1722 This is caused by a missing libstdc++.a library.
1723 This is installed as part of a specific package
1724 (e.g. libstdc++.so.devel.386).
1725 By default some 64bit Linux versions (e.g. Fedora)
1726 only install the 64bit version of the libstdc++ package.
1727 Various parts of the JDK build require a static
1728 link of the C++ runtime libraries to allow for maximum
1729 portability of the built images.
