101 <blockquote>
102 This file often describes specific requirements for what we call the
103 "minimum build environments" (MBE) for this
104 specific release of the JDK,
105 Building with the MBE will generate the most compatible
106 bits that install on, and run correctly on, the most variations
107 of the same base OS and hardware architecture.
108 These usually represent what is often called the
109 least common denominator platforms.
110 It is understood that most developers will NOT be using these
111 specific platforms, and in fact creating these specific platforms
112 may be difficult due to the age of some of this software.

185 These same sources do indeed build on many more systems than the
186 above older generation systems, again the above is just a minimum.
187 <p>
188 Compilation problems with newer or different C/C++ compilers is a
189 common problem.
190 Similarly, compilation problems related to changes to the
191 <tt>/usr/include</tt> or system header files is also a
192 common problem with newer or unreleased OS versions.
193 Please report these types of problems as bugs so that they
194 can be dealt with accordingly.

435 Building the OpenJDK
436 is done with a <tt><i>gmake</i></tt>
437 command line and various
438 environment or make variable settings that direct the make rules
439 to where various components have been installed.
440 Where possible the makefiles will attempt to located the various
441 components in the default locations or any component specific
442 variable settings.
443 When the normal defaults fail or components cannot be found,
444 the various
445 <tt>ALT_*</tt> variables (alternates)
446 can be used to help the makefiles locate components.
447 <p>
448 Refer to the bash/sh/ksh setup file
449 <tt>jdk/make/jdk_generic_profile.sh</tt>
450 if you need help in setting up your environment variables.
451 A build could be as simple as:
452 <blockquote>
453 <pre><tt>
454 bash
455 . jdk/make/jdk_generic_profile.sh
456 <i>gmake</i> sanity && <i>gmake</i>

460 Of course ksh or sh would work too.
461 But some customization will probably be necessary.

474 A few notes about using GNU make:
475 <ul>
476 <li>
477 In general, you need GNU make version 3.78.1 or newer.

488 Do NOT use <tt>/usr/bin/make</tt> on Solaris.

501 <b>WARNING:</b> Watch out for make version 3.81, it may
502 not work due to a lack of support for MS-DOS drive letter paths
503 like <tt>C:/</tt> or <tt>C:\</tt>.
504 Use a 3.80 version, or find a newer
505 version that has this problem fixed.

509 Use of this older 3.80 make.exe may require that you install the
510 libintl2.dll library or libintl2 cygwin package which is
511 no longer installed by default by the cygwin installer.

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

780 Depending on the platform, the OpenJDK build process has some basic
781 dependencies on components not part of the OpenJDK sources.
782 Some of these are specific to a platform, some even specific to
783 an architecture.
784 Each dependency will have a set of ALT variables that can be set
785 to tell the makefiles where to locate the component.
786 In most cases setting these ALT variables may not be necessary
787 and the makefiles will find defaults on the system in standard

796 For build performance reasons
797 is very important that this bootstrap JDK be made available on the

799 You should always set

820 This is a temporary situation and these binary plugs will be
821 replaced with fully open source replacements as soon as possible.
822 So currently, in order to build a complete OpenJDK image,
823 you must first download and install the appropriate
824 binary plug bundles for the OpenJDK, go to the
825 <a href="http://openjdk.java.net" target="_blank">OpenJDK</a> site and select
826 the
827 "<b>Bundles(7)</b>"

838 During the OpenJDK build process these "binary plugs"
839 for the encumbered components will be copied into your

877 A certificates file named "cacerts"
878 represents a system-wide keystore with CA certificates.
879 In JDK and JRE

881 several public CAs (e.g., VeriSign, Thawte, and Baltimore).
882 The source contain a cacerts file

1097 <strong>Linux only:</strong>
1098 Version 0.9.1 or newer of the ALSA files are
1099 required for building the OpenJDK on Linux.
1100 These Linux files are usually available from an "alsa"
1101 of "libasound"

1105 The makefiles will check this emit a sanity error if it is
1106 missing or the wrong version.
1107 <p>
1108 In particular, older Linux systems will likely not have the
1109 right version of ALSA installed, for example
1110 Redhat AS 2.1 U2 and SuSE 8.1 do not include a sufficiently
1111 recent ALSA distribution.
1112 On rpm-based systems, you can see if ALSA is installed by
1113 running this command:
1114 <pre>
1115 <tt>rpm -qa | grep alsa</tt>
1116 </pre>
1117 Both <tt>alsa</tt> and <tt>alsa-devel</tt> packages are needed.
1118 <p>
1119 If your distribution does not come with ALSA, and you can't
1120 find ALSA packages built for your particular system,
1121 you can try to install the pre-built ALSA rpm packages from
1122 <a href="http://www.freshrpms.net/" target="_blank">
1123 <tt>www.freshrpms.net</tt></a>.
1124 Note that installing a newer ALSA could
1125 break sound output if an older version of ALSA was previously

1626 <h2><a name="troubleshooting">Troubleshooting</a></h2>
1627 <blockquote>
1628 A build can fail for any number of reasons.
1629 Most failures
1630 are a result of trying to build in an environment in which all the
1631 pre-build requirements have not been met.
1632 The first step in
1633 troubleshooting a build failure is to recheck that you have satisfied
1634 all the pre-build requirements for your platform.
1635 Look for the check list of the platform you are building on in the
1636 <a href="#contents">Table of Contents</a>.
1637 <p>
1638 You can validate your build environment by using the <tt>sanity</tt>
1639 target.
1640 Any errors listed
1641 will stop the build from starting, and any warnings may result in
1642 a flawed product build.
1643 We strongly encourage you to evaluate every
1644 sanity check warning and fix it if required, before you proceed
1645 further with your build.
1646 <p>
1647 Some of the more common problems with builds are briefly described
1648 below, with suggestions for remedies.
1649 <ul>
1650 <li>
1651 <b>Slow Builds:</b>
1652 <blockquote>
1653 If your build machine seems to be overloaded from too many
1654 simultaneous C++ compiles, try setting the <tt>HOTSPOT_BUILD_JOBS</tt>
1655 variable to <tt>1</tt> (if you're using a multiple CPU
1656 machine, setting it to more than the the number of CPUs is probably
1657 not a good idea).
1658 <p>
1659 Creating the javadocs can be very slow, if you are running
1660 javadoc, consider skipping that step.
1661 <p>
1662 Faster hardware and more RAM always helps too.
1663 The VM build tends to be CPU intensive (many C++ compiles),
1664 and the rest of the JDK will often be disk intensive.
1665 <p>
1666 Faster compiles are possible using a tool called
1667 <a href="http://ccache.samba.org/" target="_blank">ccache</a>.
1668 </blockquote>
1669 </li>
1670 <li>
1671 <b>File time issues:</b>
1672 <blockquote>
1673 If you see warnings that refer to file time stamps, e.g.
1674 <blockquote>
1675 <i>Warning message:</i><tt> File `xxx' has modification time in
1676 the future.</tt>
1677 <br>
1678 <i>Warning message:</i> <tt> Clock skew detected. Your build may
1679 be incomplete.</tt>
1680 </blockquote>
1681 These warnings can occur when the clock on the build machine is out of
1682 sync with the timestamps on the source files. Other errors, apparently
1683 unrelated but in fact caused by the clock skew, can occur along with
1684 the clock skew warnings. These secondary errors may tend to obscure the
1685 fact that the true root cause of the problem is an out-of-sync clock.
1686 For example, an out-of-sync clock has been known to cause an old
1687 version of javac to be used to compile some files, resulting in errors
1688 when the pre-1.4 compiler ran across the new <tt>assert</tt> keyword
1689 in the 1.4 source code.
1690 <p>
1691 If you see these warnings, reset the clock on the build
1692 machine, run "<tt><i>gmake</i> clobber</tt>" or delete the directory
1693 containing the build output, and restart the build from the beginning.

1697 <b>Error message: <tt>Trouble writing out table to disk</tt></b>
1698 <blockquote>
1699 Increase the amount of swap space on your build machine.
1700 </blockquote>
1701 </li>
1702 <li>
1703 <b>Error Message: <tt>libstdc++ not found:</tt></b>
1704 <blockquote>
1705 This is caused by a missing libstdc++.a library.
1706 This is installed as part of a specific package
1707 (e.g. libstdc++.so.devel.386).
1708 By default some 64-bit Linux versions (e.g. Fedora)
1709 only install the 64-bit version of the libstdc++ package.
1710 Various parts of the JDK build require a static
1711 link of the C++ runtime libraries to allow for maximum
1712 portability of the built images.
