38 Some Headlines:
39 <ul>
40 <li>
41 The build is now a "<code>configure &amp;&amp; make</code>" style build
42 </li>
43 <li>
Erik Joelsson6e76eef2015-04-17 10:43:28 +020044 Any GNU make 3.81 or newer should work, except on

Kelly O'Hair2ff5bb12013-02-23 10:47:01 -080046 </li>
47 <li>
48 The build should scale, i.e. more processors should
49 cause the build to be done in less wall-clock time
50 </li>
51 <li>
52 Nested or recursive make invocations have been significantly
53 reduced, as has the total fork/exec or spawning
54 of sub processes during the build
55 </li>
56 <li>
57 Windows MKS usage is no longer supported
58 </li>
59 <li>
60 Windows Visual Studio <code>vsvars*.bat</code> and
61 <code>vcvars*.bat</code> files are run automatically
62 </li>
63 <li>
64 Ant is no longer used when building the OpenJDK

127 The OpenJDK sources are maintained with the revision control system

129 If you are new to Mercurial, please see the

132 or refer to the <a href="http://hgbook.red-bean.com/">
133 Mercurial Book</a>.
Kelly O'Hair213481a2010-12-22 12:25:52 -0800134 The first few chapters of the book provide an excellent overview of
135 Mercurial, what it is and how it works.
136 <br>
137 For using Mercurial with the OpenJDK refer to the

143 <blockquote>
144 To get the entire set of OpenJDK Mercurial repositories
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -0800145 use the script <code>get_source.sh</code> located in the
146 root repository:
Kelly O'Hair213481a2010-12-22 12:25:52 -0800147 <blockquote>
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -0800148 <code>
Erik Joelssonfad4dbf2014-04-24 10:21:58 +0200149 hg clone http://hg.openjdk.java.net/jdk9/jdk9
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -0800150 <i>YourOpenJDK</i>

154 bash ./get_source.sh
155 </code>
156 </blockquote>
157 Once you have all the repositories, keep in mind that each
Erik Joelssonf771ef42013-08-26 13:43:27 +0200158 repository is its own independent repository.
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -0800159 You can also re-run <code>./get_source.sh</code> anytime to
160 pull over all the latest changesets in all the repositories.
161 This set of nested repositories has been given the term
162 "forest" and there are various ways to apply the same
163 <code>hg</code> command to each of the repositories.
164 For example, the script <code>make/scripts/hgforest.sh</code>
165 can be used to repeat the same <code>hg</code>
166 command on every repository, e.g.
167 <blockquote>
168 <code>
169 cd <i>YourOpenJDK</i>
170 <br>
171 bash ./make/scripts/hgforest.sh status
172 </code>

Kelly O'Hair2ff5bb12013-02-23 10:47:01 -0800259 There are some very basic guidelines:
Kelly O'Hair2928b812008-09-17 13:30:32 -0700260 <ul>
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -0800261 <li>
262 Use of whitespace in source files
263 (.java, .c, .h, .cpp, and .hpp files)
264 is restricted.
265 No TABs, no trailing whitespace on lines, and files
266 should not terminate in more than one blank line.
267 </li>
268 <li>
269 Files with execute permissions should not be added
270 to the source repositories.
271 </li>
272 <li>
273 All generated files need to be kept isolated from
274 the files
275 maintained or managed by the source control system.
276 The standard area for generated files is the top level
277 <code>build/</code> directory.
278 </li>
279 <li>
280 The default build process should be to build the product
281 and nothing else, in one form, e.g. a product (optimized),
282 debug (non-optimized, -g plus assert logic), or
283 fastdebug (optimized, -g plus assert logic).
284 </li>
285 <li>
286 The <tt>.hgignore</tt> file in each repository
287 must exist and should
288 include <tt>^build/</tt>, <tt>^dist/</tt> and
289 optionally any
290 <tt>nbproject/private</tt> directories.
291 <strong>It should NEVER</strong> include
292 anything in the
293 <tt>src/</tt> or <tt>test/</tt>
294 or any managed directory area of a repository.
295 </li>
296 <li>
297 Directory names and file names should never contain
298 blanks or
299 non-printing characters.
300 </li>
301 <li>
302 Generated source or binary files should NEVER be added to
303 the repository (that includes <tt>javah</tt> output).
304 There are some exceptions to this rule, in particular
305 with some of the generated configure scripts.
306 </li>
307 <li>
308 Files not needed for typical building
309 or testing of the repository
310 should not be added to the repository.

321 The very first step in building the OpenJDK is making sure the
322 system itself has everything it needs to do OpenJDK builds.
323 Once a system is setup, it generally doesn't need to be done again.
324 <br>
325 Building the OpenJDK is now done with running a
326 <a href="#configure"><code>configure</code></a>
327 script which will try and find and verify you have everything
328 you need, followed by running
329 <a href="#gmake"><code>make</code></a>, e.g.

336 </b>
337 </blockquote>
338 Where possible the <code>configure</code> script will attempt to located the
339 various components in the default locations or via component
340 specific variable settings.
341 When the normal defaults fail or components cannot be found,
342 additional <code>configure</code> options may be necessary to help <code>configure</code>
343 find the necessary tools for the build, or you may need to
344 re-visit the setup of your system due to missing software
345 packages.
346 <br>
347 <strong>NOTE:</strong> The <code>configure</code> script
348 file does not have
349 execute permissions and will need to be explicitly run with

357 Before even attempting to use a system to build the OpenJDK
358 there are some very basic system setups needed.
359 For all systems:
360 <ul>
361 <li>
Erik Joelsson6e76eef2015-04-17 10:43:28 +0200362 Be sure the GNU make utility is version 3.81 (4.0 on

Kelly O'Hair2ff5bb12013-02-23 10:47:01 -0800368 All OpenJDK builds require access to a previously released
Stuart Markse1dd7522013-06-18 17:18:46 -0700369 JDK called the <i>bootstrap JDK</i> or <i>boot JDK.</i>
370 The general rule is that the bootstrap JDK
371 must be an instance of the previous major
372 release of the JDK. In addition, there may be
373 a requirement to use a release at or beyond a
374 particular update level.

387 For build performance reasons it
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -0800388 is very important that this bootstrap JDK be made available
389 on the local disk of the machine doing the build.
390 You should add its <code>bin</code> directory
391 to the <code>PATH</code> environment variable.
392 If <code>configure</code> has any issues finding this JDK, you may
393 need to use the <code>configure</code> option
394 <code>--with-boot-jdk</code>.

396 <li>

469 might get pre-defined for you to refer to the JDK installed on

471 You will need to unset <code>JAVA_HOME</code>.
472 It's a good idea to run <code>env</code> and verify the

561 <h5><a name="toolkit">Windows Unix Toolkit</a></h5>
562 <blockquote>
563 Building on Windows requires a Unix-like environment, notably a
564 Unix-like shell.
565 There are several such environments available of which
566 <a href="http://www.cygwin.com/">Cygwin</a> and
567 <a href="http://www.mingw.org/wiki/MSYS">MinGW/MSYS</a> are
568 currently supported for
569 the OpenJDK build. One of the differences of these
570 systems from standard Windows tools is the way
571 they handle Windows path names, particularly path names which contain
572 spaces, backslashes as path separators and possibly drive letters.
573 Depending
574 on the use case and the specifics of each environment these path
575 problems can
576 be solved by a combination of quoting whole paths, translating
577 backslashes to
578 forward slashes, escaping backslashes with additional backslashes and
579 translating the path names to their
580 <a href="http://en.wikipedia.org/wiki/8.3_filename">
581 "8.3" version</a>.
582
583 <h6><a name="cygwin">CYGWIN</a></h6>
584 <blockquote>
585 CYGWIN is an open source, Linux-like environment which tries to emulate
586 a complete POSIX layer on Windows. It tries to be smart about path names
587 and can usually handle all kinds of paths if they are correctly quoted
588 or escaped although internally it maps drive letters <code>&lt;drive&gt;:</code>
589 to a virtual directory <code>/cygdrive/&lt;drive&gt;</code>.
590 <p>
591 You can always use the <code>cygpath</code> utility to map pathnames with spaces
592 or the backslash character into the <code>C:/</code> style of pathname
593 (called 'mixed'), e.g. <code>cygpath -s -m "<i>path</i>"</code>.
594 </p>
595 <p>
596 Note that the use of CYGWIN creates a unique problem with regards to
597 setting <a href="#path"><code>PATH</code></a>. Normally on Windows
598 the <code>PATH</code> variable contains directories
599 separated with the ";" character (Solaris and Linux use ":").
600 With CYGWIN, it uses ":", but that means that paths like "C:/path"
601 cannot be placed in the CYGWIN version of <code>PATH</code> and
602 instead CYGWIN uses something like <code>/cygdrive/c/path</code>
603 which CYGWIN understands, but only CYGWIN understands.
604 </p>
605 <p>
606 The OpenJDK build requires CYGWIN version 1.7.16 or newer.
607 Information about CYGWIN can
608 be obtained from the CYGWIN website at
609 <a href="http://www.cygwin.com" target="_blank">www.cygwin.com</a>.
610 </p>
611 <p>
612 By default CYGWIN doesn't install all the tools required for building
613 the OpenJDK.
614 Along with the default installation, you need to install
615 the following tools.

715 MinGW ("Minimalist GNU for Windows") is a collection of free Windows
716 specific header files and import libraries combined with GNU toolsets that
717 allow one to produce native Windows programs that do not rely on any
718 3rd-party C runtime DLLs. MSYS is a supplement to MinGW which allows building
719 applications and programs which rely on traditional UNIX tools to
720 be present. Among others this includes tools like <code>bash</code>
721 and <code>make</code>.
722 See <a href="http://www.mingw.org/wiki/MSYS" target="_blank">MinGW/MSYS</a>
723 for more information.
724 <p>
725 Like Cygwin, MinGW/MSYS can handle different types of path formats. They
726 are internally converted to paths with forward slashes and drive letters
727 <code>&lt;drive&gt;:</code> replaced by a virtual
728 directory <code>/&lt;drive&gt;</code>. Additionally, MSYS automatically
729 detects binaries compiled for the MSYS environment and feeds them with the
730 internal, Unix-style path names. If native Windows applications are called
731 from within MSYS programs their path arguments are automatically converted
732 back to Windows style path names with drive letters and backslashes as
733 path separators. This may cause problems for Windows applications which
734 use forward slashes as parameter separator (e.g. <code>cl /nologo /I</code>)
735 because MSYS may wrongly <a href="http://mingw.org/wiki/Posix_path_conversion">
736 replace such parameters by drive letters</a>.
737 </p>
738 <p>
739 In addition to the tools which will be installed
740 by default, you have
741 to manually install the
742 <code>msys-zip</code> and
743 <code>msys-unzip</code> packages.
744 This can be easily done with the MinGW command line installer:
745 <blockquote>
746 <code>mingw-get.exe install msys-zip</code>
747 <br>
748 <code>mingw-get.exe install msys-unzip</code>

804 looks like:
805 <blockquote>
806 <b><code>bash ./configure [<i>options</i>]</code></b>

808 This will create an output directory containing the

814 <code>configure</code> will try to figure out what system you are running on
815 and where all necessary build components are.
816 If you have all prerequisites for building installed,

Kelly O'Hair2ff5bb12013-02-23 10:47:01 -08001191 How are you going to edit it?
1192 <br>
Erik Joelsson7b50e2e2013-08-30 10:13:25 +02001193 <b>A:</b> The <code>generated-configure.sh</code> file is generated (think
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -08001194 "compiled") by the autoconf tools. The source code is
Erik Joelsson7b50e2e2013-08-30 10:13:25 +02001195 in <code>configure.ac</code> and various .m4 files in common/autoconf,
1196 which are much more readable.

1200 <b>Q:</b>
Erik Joelsson7b50e2e2013-08-30 10:13:25 +02001201 Why is the <code>generated-configure.sh</code> file checked in,
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -08001202 if it is generated?
1203 <br>
1204 <b>A:</b>
1205 If it was not generated, every user would need to have the autoconf
1206 tools installed, and re-generate the <code>configure</code> file
1207 as the first step.
1208 Our goal is to minimize the work needed to be done by the user
1209 to start building OpenJDK, and to minimize
1210 the number of external dependencies required.
1211 </p>
1212
1213 <p>
1214 <b>Q:</b>
1215 Do you require a specific version of autoconf for regenerating
Erik Joelsson7b50e2e2013-08-30 10:13:25 +02001216 <code>generated-configure.sh</code>?
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -08001217 <br>
1218 <b>A:</b>
Erik Joelsson7b50e2e2013-08-30 10:13:25 +02001219 Yes, version 2.69 is required and should be easy
1220 enough to aquire on all supported operating
1221 systems. The reason for this is to avoid
1222 large spurious changes in <code>generated-configure.sh</code>.
1223 </p>
1224
1225 <p>
1226 <b>Q:</b>
1227 How do you regenerate <code>generated-configure.sh</code>
1228 after making changes to the input files?
1229 <br>
1230 <b>A:</b>
1231 Regnerating <code>generated-configure.sh</code>
1232 should always be done using the
1233 script <code>common/autoconf/autogen.sh</code> to
1234 ensure that the correct files get updated. This
1235 script should also be run after mercurial tries to
1236 merge <code>generated-configure.sh</code> as a
1237 merge of the generated file is not guaranteed to
1238 be correct.

1241 <p>
1242 <b>Q:</b>
1243 What are the files in <code>common/makefiles/support/*</code> for?
1244 They look like gibberish.
1245 <br>
1246 <b>A:</b>
1247 They are a somewhat ugly hack to compensate for command line length
1248 limitations on certain platforms (Windows, Solaris).
1249 Due to a combination of limitations in make and the shell,
1250 command lines containing too many files will not work properly.
1251 These
1252 helper files are part of an elaborate hack that will compress the
1253 command line in the makefile and then uncompress it safely.
1254 We're
1255 not proud of it, but it does fix the problem.

1290 When do I have to re-run <code>configure</code>?
1291 <br>
1292 <b>A:</b>
1293 Normally you will run <code>configure</code> only once for creating a
1294 configuration.
1295 You need to re-run configuration only if you want to change any
1296 configuration options,
1297 or if you pull down changes to the <code>configure</code> script.

1302 I have added a new source file. Do I need to modify the makefiles?

1304 <b>A:</b>
1305 Normally, no. If you want to create e.g. a new native
1306 library,
1307 you will need to modify the makefiles. But for normal file
1308 additions or removals, no changes are needed. There are certan
1309 exceptions for some native libraries where the source files are spread
Erik Joelssonf771ef42013-08-26 13:43:27 +02001310 over many directories which also contain sources for other
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -08001311 libraries. In these cases it was simply easier to create include lists
Erik Joelssonf771ef42013-08-26 13:43:27 +02001312 rather than excludes.

1316 <b>Q:</b>
1317 When I run <code>configure --help</code>, I see many strange options,
1318 like <code>--dvidir</code>. What is this?
1319 <br>
1320 <b>A:</b>
1321 Configure provides a slew of options by default, to all projects
1322 that use autoconf. Most of them are not used in OpenJDK,
1323 so you can safely ignore them. To list only OpenJDK specific features,
1324 use <code>configure --help=short</code> instead.
1325 </p>
1326
1327 <p>
1328 <b>Q:</b>
1329 <code>configure</code> provides OpenJDK-specific features such as
Erik Joelssonf771ef42013-08-26 13:43:27 +02001330 <code>--with-builddeps-server</code> that are not
1331 described in this document. What about those?
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -08001332 <br>
1333 <b>A:</b>
1334 Try them out if you like! But be aware that most of these are
1335 experimental features.
1336 Many of them don't do anything at all at the moment; the option
Erik Joelssonf771ef42013-08-26 13:43:27 +02001337 is just a placeholder. Others depend on
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -08001338 pieces of code or infrastructure that is currently
1339 not ready for prime time.
1340 </p>
1341
1342 <p>
1343 <b>Q:</b>
1344 How will you make sure you don't break anything?
1345 <br>
1346 <b>A:</b>
1347 We have a script that compares the result of the new build system
1348 with the result of the old. For most part, we aim for (and achieve)
1349 byte-by-byte identical output. There are however technical issues
1350 with e.g. native binaries, which might differ in a byte-by-byte
1351 comparison, even
1352 when building twice with the old build system.
1353 For these, we compare relevant aspects
1354 (e.g. the symbol table and file size).
1355 Note that we still don't have 100%
1356 equivalence, but we're close.
1357 </p>
1358
1359 <p>
1360 <b>Q:</b>
1361 I noticed this thing X in the build that looks very broken by design.
1362 Why don't you fix it?
1363 <br>
1364 <b>A:</b>
1365 Our goal is to produce a build output that is as close as
1366 technically possible to the old build output.
1367 If things were weird in the old build,
1368 they will be weird in the new build.
1369 Often, things were weird before due to obscurity,
1370 but in the new build system the weird stuff comes up to the surface.
1371 The plan is to attack these things at a later stage,
1372 after the new build system is established.
1373 </p>
1374
1375 <p>
1376 <b>Q:</b>
1377 The code in the new build system is not that well-structured.
1378 Will you fix this?
1379 <br>
1380 <b>A:</b>
1381 Yes! The new build system has grown bit by bit as we converted
1382 the old system. When all of the old build system is converted,
1383 we can take a step back and clean up the structure of the new build
1384 system. Some of this we plan to do before replacing the old build
1385 system and some will need to wait until after.

1387
1388 <p>
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -08001389 <b>Q:</b>
1390 Is anything able to use the results of the new build's default make target?
1391 <br>
1392 <b>A:</b>
1393 Yes, this is the minimal (or roughly minimal)
1394 set of compiled output needed for a developer to actually
1395 execute the newly built JDK. The idea is that in an incremental
1396 development fashion, when doing a normal make,
1397 you should only spend time recompiling what's changed
1398 (making it purely incremental) and only do the work that's
1399 needed to actually run and test your code.
1400 The packaging stuff that is part of the <code>images</code>
1401 target is not needed for a normal developer who wants to
1402 test his new code. Even if it's quite fast, it's still unnecessary.
1403 We're targeting sub-second incremental rebuilds! ;-)
1404 (Or, well, at least single-digit seconds...)
1405 </p>
1406
1407 <p>
1408 <b>Q:</b>
1409 I usually set a specific environment variable when building,
1410 but I can't find the equivalent in the new build.
1411 What should I do?
1412 <br>
1413 <b>A:</b>
Erik Joelssonf771ef42013-08-26 13:43:27 +02001414 It might very well be that we have neglected to add support for
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -08001415 an option that was actually used from outside the build system.

1424 <p>Building OpenJDK requires a lot of horsepower.
1425 Some of the build tools can be adjusted to utilize more or less
1426 of resources such as
1427 parallel threads and memory.
1428 The <code>configure</code> script analyzes your system and selects reasonable
1429 values for such options based on your hardware.
1430 If you encounter resource problems, such as out of memory conditions,
1431 you can modify the detected values with:</p>
1432
1433 <ul>
1434 <li>
1435 <b><code>--with-num-cores</code></b>
1436 &mdash;
1437 number of cores in the build system,
1438 e.g. <code>--with-num-cores=8</code>
1439 </li>
1440 <li>
1441 <b><code>--with-memory-size</code></b>
1442 &mdash; memory (in MB) available in the build system,
1443 e.g. <code>--with-memory-size=1024</code>
1444 </li>
1445 </ul>
1446
1447 <p>It might also be necessary to specify the JVM arguments passed
1448 to the Bootstrap JDK, using e.g.
1449 <code>--with-boot-jdk-jvmargs="-Xmx8G -enableassertions"</code>.
1450 Doing this will override the default JVM arguments
1451 passed to the Bootstrap JDK.</p>
1452
1453
1454 <p>One of the top goals of the new build system is to improve the
1455 build performance and decrease the time needed to build. This will
1456 soon also apply to the java compilation when the Smart Javac wrapper
Erik Joelssonfad4dbf2014-04-24 10:21:58 +02001457 is fully supported.</p>

1460 you will get a performance summary,
1461 indicating how well the build will perform. Here you will
1462 also get performance hints.
1463 If you want to build fast, pay attention to those!</p>

1465 <h4>Building with ccache</h4>
1466
Erik Joelsson24bc7732015-02-10 12:25:44 +01001467 <p>The OpenJDK build supports building with ccache
1468 when using gcc or clang. Using ccache can
1469 radically speed up compilation of native code if
1470 you often rebuild the same sources. Your milage
1471 may vary however so we recommend evaluating it for
1472 yourself. To enable it, make sure it's on the path
1473 and configure with <code>--enable-ccache</code>.</p>
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -08001474
1475 <h4>Building on local disk</h4>
1476
1477 <p>If you are using network shares, e.g. via NFS, for your source code,
1478 make sure the build directory is situated on local disk.
1479 The performance
1480 penalty is extremely high for building on a network share,
1481 close to unusable.</p>
1482
1483 <h4>Building only one JVM</h4>
1484
1485 <p>The old build builds multiple JVMs on 32-bit systems (client and
1486 server; and on Windows kernel as well). In the new build we have
1487 changed this default to only build server when it's available. This
1488 improves build times for those not interested in multiple JVMs. To
1489 mimic the old behavior on platforms that support it,
1490 use <code>--with-jvm-variants=client,server</code>.</p>
1491
1492 <h4>Selecting the number of cores to build on</h4>
1493
1494 <p>By default, <code>configure</code> will analyze your machine and run the make
1495 process in parallel with as many threads as you have cores. This
1496 behavior can be overridden, either "permanently" (on a <code>configure</code>
1497 basis) using <code>--with-num-cores=N</code> or for a single build
1498 only (on a make basis), using <code>make JOBS=N</code>.</p>
1499
1500 <p>If you want to make a slower build just this time, to save some CPU
1501 power for other processes, you can run
1502 e.g. <code>make JOBS=2</code>. This will force the makefiles
1503 to only run 2 parallel processes, or even <code>make JOBS=1</code>
1504 which will disable parallelism.</p>
1505
1506 <p>If you want to have it the other way round, namely having slow
1507 builds default and override with fast if you're
1508 impatient, you should call <code>configure</code> with
1509 <code>--with-num-cores=2</code>, making 2 the default.
1510 If you want to run with more
1511 cores, run <code>make JOBS=8</code></p>

1518 <h4>Solving build problems</h4>
1519
1520 <blockquote>
1521 If the build fails (and it's not due to a compilation error in
1522 a source file you've changed), the first thing you should do
1523 is to re-run the build with more verbosity.
1524 Do this by adding <code>LOG=debug</code> to your make command line.
1525 <br>
1526 The build log (with both stdout and stderr intermingled,
1527 basically the same as you see on your console) can be found as
1528 <code>build.log</code> in your build directory.
1529 <br>
1530 You can ask for help on build problems with the new build system
1531 on either the
1532 <a href="http://mail.openjdk.java.net/mailman/listinfo/build-dev">
1533 build-dev</a>
1534 or the
1535 <a href="http://mail.openjdk.java.net/mailman/listinfo/build-infra-dev">
1536 build-infra-dev</a>
1537 mailing lists. Please include the relevant parts
1538 of the build log.
1539 <br>
1540 A build can fail for any number of reasons.
1541 Most failures
1542 are a result of trying to build in an environment in which all the
1543 pre-build requirements have not been met.
1544 The first step in
1545 troubleshooting a build failure is to recheck that you have satisfied
1546 all the pre-build requirements for your platform.
1547 Scanning the <code>configure</code> log is a good first step, making
1548 sure that what it found makes sense for your system.
1549 Look for strange error messages or any difficulties that
1550 <code>configure</code> had in finding things.
1551 <br>
1552 Some of the more common problems with builds are briefly
1553 described
1554 below, with suggestions for remedies.
1555 <ul>
1556 <li>
1557 <b>Corrupted Bundles on Windows:</b>
1558 <blockquote>
1559 Some virus scanning software has been known to
1560 corrupt the
1561 downloading of zip bundles.
1562 It may be necessary to disable the 'on access' or
1563 'real time'
1564 virus scanning features to prevent this corruption.
1565 This type of "real time" virus scanning can also
1566 slow down the
1567 build process significantly.
1568 Temporarily disabling the feature, or excluding the build
1569 output directory may be necessary to get correct and
1570 faster builds.
1571 </blockquote>
1572 </li>
1573 <li>
1574 <b>Slow Builds:</b>
1575 <blockquote>
1576 If your build machine seems to be overloaded from too many
1577 simultaneous C++ compiles, try setting the
1578 <code>JOBS=1</code> on the <code>make</code> command line.
1579 Then try increasing the count slowly to an acceptable
1580 level for your system. Also:
1581 <blockquote>
1582 Creating the javadocs can be very slow,
1583 if you are running
1584 javadoc, consider skipping that step.
1585 <br>
1586 Faster CPUs, more RAM, and a faster DISK usually helps.
1587 The VM build tends to be CPU intensive
1588 (many C++ compiles),
1589 and the rest of the JDK will often be disk intensive.
1590 <br>
1591 Faster compiles are possible using a tool called
1592 <a href="http://ccache.samba.org/" target="_blank">ccache</a>.
1593 </blockquote>
1594 </blockquote>
1595 </li>
1596 <li>
1597 <b>File time issues:</b>
1598 <blockquote>
1599 If you see warnings that refer to file time stamps, e.g.
1600 <blockquote>
1601 <i>Warning message:</i><code>
1602 File `xxx' has modification time in
1603 the future.</code>
1604 <br>
1605 <i>Warning message:</i> <code> Clock skew detected.
1606 Your build may
1607 be incomplete.</code>
1608 </blockquote>
1609 These warnings can occur when the clock on the build
1610 machine is out of
1611 sync with the timestamps on the source files.
1612 Other errors, apparently
1613 unrelated but in fact caused by the clock skew,
1614 can occur along with
1615 the clock skew warnings.
1616 These secondary errors may tend to obscure the
1617 fact that the true root cause of the problem
1618 is an out-of-sync clock.
1619 <p>
1620 If you see these warnings, reset the clock on the
1621 build
1622 machine, run "<code><i>gmake</i> clobber</code>"
1623 or delete the directory
1624 containing the build output, and restart the
1625 build from the beginning.

1629 <b>Error message:
1630 <code>Trouble writing out table to disk</code></b>
1631 <blockquote>
1632 Increase the amount of swap space on your build machine.
1633 This could be caused by overloading the system and
1634 it may be necessary to use:
1635 <blockquote>
1636 <code>make JOBS=1</code>
1637 </blockquote>
1638 to reduce the load on the system.
1639 </blockquote>
1640 </li>
1641 <li>
1642 <b>Error Message:
1643 <code>libstdc++ not found:</code></b>
1644 <blockquote>
1645 This is caused by a missing libstdc++.a library.
1646 This is installed as part of a specific package
1647 (e.g. libstdc++.so.devel.386).
1648 By default some 64-bit Linux versions (e.g. Fedora)
1649 only install the 64-bit version of the libstdc++ package.
1650 Various parts of the JDK build require a static
1651 link of the C++ runtime libraries to allow for maximum
1652 portability of the built images.

Kelly O'Hair2ff5bb12013-02-23 10:47:01 -08001792 This file often describes specific requirements for what we
1793 call the
1794 "minimum build environments" (MBE) for this
1795 specific release of the JDK.
1796 What is listed below is what the Oracle Release
1797 Engineering Team will use to build the Oracle JDK product.
1798 Building with the MBE will hopefully generate the most compatible
1799 bits that install on, and run correctly on, the most variations
1800 of the same base OS and hardware architecture.
1801 In some cases, these represent what is often called the
1802 least common denominator, but each Operating System has different
1803 aspects to it.
J. Duke686d76f2007-12-01 00:00:00 +00001804 <p>
Kelly O'Hair2ff5bb12013-02-23 10:47:01 -08001805 In all cases, the Bootstrap JDK version minimum is critical,
1806 we cannot guarantee builds will work with older Bootstrap JDK's.
1807 Also in all cases, more RAM and more processors is better,
1808 the minimums listed below are simply recommendations.
1809 <p>
1810 With Solaris and Mac OS X, the version listed below is the
1811 oldest release we can guarantee builds and works, and the
1812 specific version of the compilers used could be critical.
1813 <p>
1814 With Windows the critical aspect is the Visual Studio compiler
1815 used, which due to it's runtime, generally dictates what Windows
1816 systems can do the builds and where the resulting bits can
1817 be used.<br>
1818 <b>NOTE: We expect a change here off these older Windows OS releases
1819 and to a 'less older' one, probably Windows 2008R2 X64.</b>
1820 <p>
1821 With Linux, it was just a matter of picking a
1822 stable distribution that is a good representative for Linux
1823 in general.<br>
1824 <b>NOTE: We expect a change here from Fedora 9 to something else,
1825 but it has not been completely determined yet, possibly
1826 Ubuntu 12.04 X64, unbiased community feedback would be welcome on
1827 what a good choice would be here.</b>
1828 <p>
1829 It is understood that most developers will NOT be using these
1830 specific versions, and in fact creating these specific versions
1831 may be difficult due to the age of some of this software.
1832 It is expected that developers are more often using the more
1833 recent releases and distributions of these operating systems.
1834 <p>
1835 Compilation problems with newer or different C/C++ compilers is a
1836 common problem.
1837 Similarly, compilation problems related to changes to the
1838 <code>/usr/include</code> or system header files is also a
1839 common problem with older, newer, or unreleased OS versions.
1840 Please report these types of problems as bugs so that they
1841 can be dealt with accordingly.

1933 <code>yum-builddep java-1.7.0-openjdk</code>
1934 <br>
1935 <code>yum install gcc gcc-c++</code>
1936 </blockquote>
1937 <p>
1938 In addition, it's necessary to set a few environment

1952 you need to make sure you have
1953 the following Development bundles installed:
1954 <blockquote>
1955 <ul>
1956 <li>Development Libraries</li>
1957 <li>Development Tools</li>

1974 and installed easily enough from
1975 <a href="http://downloads.sourceforge.net/freetype">
1976 the freetype site</a>.
1977 Build and install with something like:
1978 <blockquote>
1979 <code>bash ./configure</code>
1980 <br>
1981 <code>make</code>
1982 <br>
1983 <code>sudo -u root make install</code>
1984 </blockquote>
1985 <p>
1986 Mercurial packages could not be found easily, but a Google
1987 search should find ones, and they usually include Python if
1988 it's needed.

2379 <dd>
2380 Set to the target architecture of a
2381 cross-compilation build. If set, this
2382 variable is used to signify that we are
2383 cross-compiling. The expectation
2384 is that
2385 <a href="#ALT_COMPILER_PATH"><code>ALT_COMPILER_PATH</code></a>
2386 is set
2387 to point to the cross-compiler and that any
2388 cross-compilation specific flags
2389 are passed using
2390 <a href="#EXTRA_CFLAGS"><code>EXTRA_CFLAGS</code></a>.
2391 The <a href="#ALT_OPENWIN_HOME"><code>ALT_OPENWIN_HOME</code></a>
2392 variable should
2393 also be set to point to the graphical header files
2394 (e.g. X11) provided with
2395 the cross-compiler.
2396 When cross-compiling we skip execution of any demos
2397 etc that may be built, and
2398 also skip binary-file verification.
2399 </dd>
2400 <dt><code><a name="EXTRA_CFLAGS">EXTRA_CFLAGS</a></code> </dt>
2401 <dd>
2402 Used to pass cross-compilation options to the
2403 cross-compiler.
2404 These are added to the <code>CFLAGS</code>
2405 and <code>CXXFLAGS</code> variables.
2406 </dd>
2407 <dt><code><a name="USE_ONLY_BOOTDIR_TOOLS">USE_ONLY_BOOTDIR_TOOLS</a></code> </dt>
2408 <dd>
2409 Used primarily for cross-compilation builds
2410 (and always set in that case)
2411 this variable indicates that tools from the
2412 boot JDK should be used during
2413 the build process, not the tools
2414 (<code>javac</code>, <code>javah</code>, <code>jar</code>)
2415 just built (which can't execute on the build host).
2416 </dd>
2417 <dt><code><a name="HOST_CC">HOST_CC</a></code> </dt>
2418 <dd>
2419 The location of the C compiler to generate programs
2420 to run on the build host.
2421 Some parts of the build generate programs that are
2422 then compiled and executed
2423 to produce other parts of the build. Normally the
2424 primary C compiler is used
2425 to do this, but when cross-compiling that would be
2426 the cross-compiler and the
2427 resulting program could not be executed.
2428 On Linux this defaults to <code>/usr/bin/gcc</code>;
2429 on other platforms it must be
2430 set explicitly.
2431 </dd>
2432 </dl>
2433 <dt><strong>Specialized Build Options:</strong></dt>
2434 <dd>
2435 Some build variables exist to support specialized build
2436 environments and/or specialized
2437 build products. Their use is only supported in those contexts:
2438 <dl>
2439 <dt><code><a name="BUILD_CLIENT_ONLY">BUILD_CLIENT_ONLY</a></code> </dt>
2440 <dd>
2441 Indicates this build will only contain the
2442 Hotspot client VM. In addition to
2443 controlling the Hotspot build target,
2444 it ensures that we don't try to copy
2445 any server VM files/directories,
2446 and defines a default <code>jvm.cfg</code> file
2447 suitable for a client-only environment.
2448 Using this in a 64-bit build will
2449 generate a sanity warning as 64-bit client
2450 builds are not directly supported.
2451 </dd>
2452 <dt><code><a name="BUILD_HEADLESS_ONLY"></a>BUILD_HEADLESS_ONLY</code> </dt>
2453 <dd>
2454 Used when the build environment has no graphical
2455 capabilities at all. This
2456 excludes building anything that requires graphical
2457 libraries to be available.
2458 </dd>
2459 <dt><code><a name="JAVASE_EMBEDDED"></a>JAVASE_EMBEDDED</code> </dt>
2460 <dd>
2461 Used to indicate this is a build of the Oracle
2462 Java SE Embedded product.
2463 This will enable the directives included in the
2464 SE-Embedded specific build
2465 files.
2466 </dd>
2467 <dt><code><a name="LIBZIP_CAN_USE_MMAP">LIBZIP_CAN_USE_MMAP</a></code> </dt>
2468 <dd>
2469 If set to false, disables the use of mmap by the
2470 zip utility. Otherwise,
2471 mmap will be used.
2472 </dd>
2473 <dt><code><a name="COMPRESS_JARS"></a>COMPRESS_JARS</code> </dt>
2474 <dd>
2475 If set to true, causes certain jar files that
2476 would otherwise be built without
2477 compression, to use compression.
2478 </dd>
