85 <p>
86 This file often describes specific requirements for what we call the
87 "minimum build environments" (MBE) for the JDK.
88 Building with the MBE will generate the most compatible
89 bits that install on, and run correctly on, the most variations
90 of the same base OS and hardware architecture.
91 These usually represent what is often called the
92 least common denominator platforms.
93 It is understood that most developers will NOT be using these
94 specific platforms, and in fact creating these specific platforms
95 may be difficult due to the age of some of this software.

100 OpenJDK:

377 Building the

379 is done with a <tt><i>gmake</i></tt>
380 command line and various
381 environment or make variable settings that direct the make rules
382 to where various components have been installed.
383 Where possible the makefiles will attempt to located the various
384 components in the default locations or any component specific
385 variable settings.
386 When the normal defaults fail or components cannot be found,
387 the various
388 <tt>ALT_*</tt> variables (alternates)
389 can be used to help the makefiles locate components.
390 <p>
391 Refer to the bash/sh/ksh setup file
392 <tt>jdk/make/jdk_generic_profile.sh</tt>
393 if you need help in setting up your environment variables.
394 A build could be as simple as:
395 <blockquote>
396 <pre><tt>
397 bash
398 . jdk/make/jdk_generic_profile.sh
399 <i>gmake</i> sanity && <i>gmake</i>

402 <p>
403 Of course ksh or sh would work too.
404 But some customization will probably be necessary.

423 A few notes about using GNU make:
424 <ul>
425 <li>
426 In general, you need GNU make version 3.78.1 or newer.
427 </li>
428 <li>
429 Place the location of the GNU make binary in the <tt>PATH</tt>.

432 <strong>Linux:</strong>
433 The <tt>/usr/bin/make</tt> command should work fine for you.
434 </li>
435 <li>
436 <strong>Solaris:</strong>
437 Do NOT use <tt>/usr/bin/make</tt> on Solaris.
438 If your Solaris system has the software
439 from the Solaris Companion CD installed,
440 you should use <tt>gmake</tt>
441 which will be located in either the <tt>/opt/sfw/bin</tt> or
442 <tt>/usr/sfw/bin</tt> directory.
443 </li>
444 <li>
445 <strong>Windows:</strong>
446 Make sure you start your build inside a bash/sh/ksh shell.
447 <br>
448 <b>WARNING:</b> Watch out for make version 3.81, it may
449 not work due to a lack of support for drive letter paths
450 like <tt>C:/</tt>. Use a 3.80 version, or find a newer
451 version that has this problem fixed.

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

678 Depending on the platform, the

681 dependencies on components not part of the
682 OpenJDK
683 sources.
684 Some of these are specific to a platform, some even specific to
685 an architecture.
686 Each dependency will have a set of ALT variables that can be set
687 to tell the makefiles where to locate the component.
688 In most cases setting these ALT variables may not be necessary
689 and the makefiles will find defaults on the system in standard
690 install locations or through component specific variables.
692 <h4><a name="bootjdk">Bootstrap JDK</a></h4>
694 <blockquote>
695 <p>
696 All

700 The JDK 6 binaries can be downloaded from Sun's
701 <a href="http://java.sun.com/javase/1.6.0/download.html">JDK 6 download site</a>.
702 For build performance reasons
703 is very important that this bootstrap JDK be made available on the
704 local disk of the machine doing the build.
705 You should always set
706 <tt><a href="#ALT_BOOTDIR">ALT_BOOTDIR</a></tt>
707 to point to the location of
708 the bootstrap JDK installation, this is the directory pathname
709 that contains a <tt>bin, lib, and include</tt>

726 Not all of the source code that makes up the JDK is available

728 In order to build an OpenJDK binary from source code,
729 you must first download and install the appropriate
730 binary plug bundles from the OpenJDK, go to the

750 A certificates file named "cacerts"
751 represents a system-wide keystore with CA certificates.
752 In JDK and JRE
753 binary bundles, the "cacerts" file contains root CA certificates from
754 several public CAs (e.g., VeriSign, Thawte, and Baltimore).
755 The source contain a cacerts file
756 without CA root certificates.
757 Formal JDK builders will need to secure
758 permission from each public CA and include the certificates into their
759 own custom cacerts file.
760 Failure to provide a populated cacerts file
761 will result in verification errors of a certificate chain during runtime.

1148 binaries and associated files in the <tt>j2sdk-image</tt>
1149 directory in the output directory.
1150 The default output directory is
1151 <tt>build/<i>platform</i></tt>,
1152 where <tt><i>platform</i></tt> is one of
1153 <tt><ul>
1154 <li>solaris-sparc</li>
1155 <li>solaris-sparcv9</li>
1156 <li>solaris-i586</li>
1157 <li>solaris-amd64</li>
1158 <li>linux-i586</li>
1159 <li>linux-amd64</li>
1160 <li>windows-i586</li>
1161 <li>windows-amd64</li>
1162 </ul></tt>
1163 In particular, the
1164 <tt>build/<i>platform</i>/j2sdk-image/bin</tt>
1165 directory should contain executables for the
1166 OpenJDK
1167 tools and utilities.
1168 <p>
1169 You can test that the build completed properly by using the build
1170 to run the various demos that you will find in the
1171 <tt>build/<i>platform</i>/j2sdk-image/demo</tt>
1172 directory.
1173 <p>
1174 The provided regression tests can be run with the <tt>jtreg</tt>
1175 utility from
1176 <a href="http://openjdk.java.net/jtreg/">the jtreg site</a>.

1209 binaries.
1210 The Solaris build supports either 32-bit or 64-bit builds, but
1211 Windows and Linux will support only one, depending on the specific
1212 OS being used.
1213 Normally, setting this variable is only necessary on Solaris.
1214 Set <tt>ARCH_DATA_MODEL</tt> to <tt>32</tt> for generating 32-bit binaries,

1317 <h2><a name="troubleshooting">Troubleshooting</a></h2>
1319 <blockquote>
1320 <p>
1321 A build can fail for any number of reasons.
1322 Most failures
1323 are a result of trying to build in an environment in which all the
1324 pre-build requirements have not been met.
1325 The first step in
1326 troubleshooting a build failure is to recheck that you have satisfied
1327 all the pre-build requirements for your platform.
1328 Look for the check list of the platform you are building on in the
1329 <a href="#contents">Table of Contents</a>.
1331 <p>
1332 You can validate your build environment by using the <tt>sanity</tt>
1333 target.
1334 Any errors listed
1335 will stop the build from starting, and any warnings may result in
1336 a flawed product build.
1337 We strongly encourage you to evaluate every
1338 sanity check warning and fix it if required, before you proceed
1339 further with your build.
1341 <p>
1342 Some of the more common problems with builds are briefly described
1343 below, with suggestions for remedies.
1345 <ul>
1346 <li>
1347 <b>Slow Builds:</b>
1348 <blockquote>
1349 <p>
1350 If your build machine seems to be overloaded from too many
1351 simultaneous C++ compiles, try setting the <tt>HOTSPOT_BUILD_JOBS</tt>
1352 variable to <tt>1</tt> (if you're using a multiple CPU
1353 machine, setting it to more than the the number of CPUs is probably
1354 not a good idea).
1355 <p>
1356 Creating the javadocs can be very slow, if you are running
1357 javadoc, consider skipping that step.
1358 <p>
1359 Faster hardware and more RAM always helps too.
1360 The VM build tends to be CPU intensive (many C++ compiles),
1361 and the rest of the JDK will often be disk intensive.
1362 <p>
1363 Faster compiles are possible using a tool called
1364 <a href="http://ccache.samba.org/">ccache</a>.
1365 </blockquote>
1366 </li>
1367 <li>
1368 <b>File time issues:</b>
1369 <blockquote>
1370 <p>
1371 If you see warnings that refer to file time stamps, e.g.
1372 <blockquote>
1373 <i>Warning message:</i><tt> File `xxx' has modification time in
1374 the future.</tt>
1375 <br>
1376 <i>Warning message:</i> <tt> Clock skew detected. Your build may
1377 be incomplete.</tt>
1378 </blockquote>
1379 <p>
1380 These warnings can occur when the clock on the build machine is out of
1381 sync with the timestamps on the source files. Other errors, apparently
1382 unrelated but in fact caused by the clock skew, can occur along with
1383 the clock skew warnings. These secondary errors may tend to obscure the
1384 fact that the true root cause of the problem is an out-of-sync clock.
1385 For example, an out-of-sync clock has been known to cause an old
1386 version of javac to be used to compile some files, resulting in errors
1387 when the pre-1.4 compiler ran across the new <tt>assert</tt> keyword
1388 in the 1.4 source code.
1389 <p>
1390 If you see these warnings, reset the clock on the build
1391 machine, run "<tt><i>gmake</i> clobber</tt>" or delete the directory
1392 containing the build output, and restart the build from the beginning.
1393 </blockquote>
1394 </li>
1395 <li>
1396 <b>Error message: <tt>Trouble writing out table to disk</tt></b>
1397 <blockquote>
1398 <p>
1399 Increase the amount of swap space on your build machine.
1400 </blockquote>
1401 </li>
1402 <li>
1403 <b>Error Message: <tt>libstdc++ not found:</tt></b>
1404 <blockquote>
1405 This is caused by a missing libstdc++.a library.
1406 This is installed as part of a specific package
1407 (e.g. libstdc++.so.devel.386).
1408 By default some 64bit Linux versions (e.g. Fedora)
1409 only install the 64bit version of the libstdc++ package.
1410 Various parts of the JDK build require a static
1411 link of the C++ runtime libraries to allow for maximum
1412 portability of the built images.
1413 </blockquote>
1414 </li>
1415 <li>
1416 <b>Error Message: <tt>cannot restore segment prot after reloc</tt></b>
1417 <blockquote>
1418 This is probably an issue with SELinux (See
1419 <a href="http://en.wikipedia.org/wiki/SELinux">http://en.wikipedia.org/wiki/SELinux</a>).
1420 Parts of the VM is built without the <tt>-fPIC</tt> for
