   136                 To get the entire set of OpenJDK Mercurial repositories
   137                 use the script <code>get_source.sh</code> located in the root repository:

   163             This file often describes specific requirements for what we call the
   164             "minimum build environments" (MBE) for this 
   165             specific release of the JDK,
   166             Building with the MBE will generate the most compatible
   167             bits that install on, and run correctly on, the most variations
   168             of the same base OS and hardware architecture.
   169             These usually represent what is often called the
   170             least common denominator platforms.
   171             It is understood that most developers will NOT be using these 
   172             specific platforms, and in fact creating these specific platforms
   173             may be difficult due to the age of some of this software.

   252             common problem with newer or unreleased OS versions.
   253             Please report these types of problems as bugs so that they
   254             can be dealt with accordingly.

   482                 After installing <a href="http://opensolaris.org">OpenSolaris</a> 2009.06 
   483                 you need to install several build dependencies. 
   484                 The simplest way to install the build dependencies is to 
   485                 execute the following commands:
   486                 <p/>
   487                 <code>pfexec pkg install SUNWgmake SUNWj6dev SUNWant sunstudioexpress SUNWcups SUNWzip SUNWunzip SUNWxwhl SUNWxorg-headers SUNWaudh SUNWfreetype2</code>
   488                 <p/>
   489                 In addition, it is necessary to set a few environment variables for the build:
   490                 <p/>
   491                 <code>export LANG=C ALT_COMPILER_PATH=/opt/SunStudioExpress/bin/ ALT_CUPS_HEADERS_PATH=/usr/include/</code>
   492                 <p/>
   493                 Finally, you need to make sure that the build process can find the Sun Studio compilers:
   494                 <p/>
   495                 <code>export PATH=$PATH:/opt/SunStudioExpress/bin/</code>

   531                     do not contain the sources for JAXP or JAX-WS.
   532                     These products have their own open source procedures at their
   533                     <a href="http://jaxp.java.net/">JAXP</a> and
   534                     <a href="http://jax-ws.java.net/">JAX-WS</a> home pages.
   535                     The OpenJDK project does need access to these sources to build
   536                     a complete JDK image because JAXP and JAX-WS are part of the JDK.
   537                     The current process for delivery of the JAXP and JAX-WS sources
   538                     involves so called "source drop bundles" downloaded from a public
   539                     website.
   540                     There are many reasons for this current mechanism, and it is
   541                     understood that this is not ideal for the open source community.
   542                     It is possible this process could change in the future.

   602                         tell the ant script that the download of the zip bundle is
   603                         acceptable.

   607                         source bundles would be to download them once, place them
   608                         in a directory outside the repositories, and then set

   698                     the OpenJDK build with the make utility provided by Cygwin will <strong>not</strong>
   699                     work because it does not support drive letters in paths. Make sure that
   700                     your version of make will be found before the Cygwins default make by 
   701                     setting an appropriate <tt>PATH</tt> environment variable or by removing
   702                     Cygwin's make after you built your own make version.<br/>
   703                     <strong>MinGW/MSYS</strong> builds can use the default make which

   921             Building on Windows requires a Unix-like environment, notably a Unix-like shell.
   922             There are several such environments available of which 
   923             <a href="http://www.mkssoftware.com/products/tk/ds_tkdev.asp">MKS</a>,

   926             the OpenJDK build. One of the differences of these three systems is the way
   927             they handle Windows path names, particularly path names which contain
   928             spaces, backslashes as path separators and possibly drive letters. Depending
   929             on the use case and the specifics of each environment these path problems can
   930             be solved by a combination of quoting whole paths, translating backslashes to
   931             forward slashes, escaping backslashes with additional backslashes and
   932             translating the path names to their <a href="http://en.wikipedia.org/wiki/8.3_filename">

   938                 require nearly twice the time (about 180%) of MKS builds (e.g. on a

   950                 make. In pre-OpenJDK times it was the only supported build environment on
   951                 Windows. The MKS tools support Windows paths with drive letters and
   952                 forward slashes as path separator. Paths in environment variables like (for
   953                 example) <tt>PATH</tt> are separated by semicolon '<tt>;</tt>'.
   954             </p>
   955             <p>
   956                 Recent versions of MKS provide the <tt>dosname</tt> utility to convert paths
   957                 with spaces to short (8.3) path names,e .g.
   958                 <tt>dosname -s "<i>path</i>"</tt>.   
   959             </p>
   960             <p>
   961                 If you are using the MKS environment, you need a native Windows version
   962                 of Gnu make <a href="#buildgmake">which you can easily build yourself</a>.

   965                 <strong>Cygwin:</strong>
   966                 is an open source, Linux-like environment which tries to emulate
   967                 a complete POSIX layer on Windows. It tries to be smart about path names
   968                 and can usually handle all kinds of paths if they are correctly quoted
   969                 or escaped although internally it maps drive letters <tt>&lt;drive&gt;:</tt> 
   970                 to a virtual directory <tt>/cygdrive/&lt;drive&gt;</tt>.
   971             </p>
   972             <p>
   973                 You can always use the <tt>cygpath</tt> utility to map pathnames with spaces
   974                 or the backslash character into the <tt>C:/</tt> style of pathname
   975                 (called 'mixed'), e.g. <tt>cygpath -s -m "<i>path</i>"</tt>.
   976             </p>
   977             <p>
   978                 Note that the use of CYGWIN creates a unique problem with regards to
   979                 setting <a href="#path"><tt>PATH</tt></a>. Normally on Windows
   980                 the <tt>PATH</tt> variable contains directories
   981                 separated with the ";" character (Solaris and Linux use ":").
   982                 With CYGWIN, it uses ":", but that means that paths like "C:/path"
   983                 cannot be placed in the CYGWIN version  of <tt>PATH</tt> and
   984                 instead CYGWIN uses something like <tt>/cygdrive/c/path</tt>
   985                 which CYGWIN understands, but only CYGWIN understands.
   986             </p>
   987             <p>
   988                 If you are using the Cygwin environment, you need to 
   989                 <a href="#buildgmake">compile your own version</a>
   990                 of GNU make because the default Cygwin make can not handle drive letters in paths. 
   991             </p>

   993                 <strong>MinGW/MSYS:</strong> 
   994                 MinGW ("Minimalist GNU for Windows") is a collection of free Windows
   995                 specific header files and import libraries combined with GNU toolsets that
   996                 allow one to produce native Windows programs that do not rely on any
   997                 3rd-party C runtime DLLs. MSYS is a supplement to MinGW which allows building
   998                 applications and programs which rely on traditional UNIX tools to
   999                 be present. Among others this includes tools like <tt>bash</tt> and <tt>make</tt>.
  1000             </p>
  1001             <p>
  1002                 Like Cygwin, MinGW/MSYS can handle different types of path formats. They
  1003                 are internally converted to paths with forward slashes and drive letters
  1004                 <tt>&lt;drive&gt;:</tt> replaced by a virtual
  1005                 directory <tt>/&lt;drive&gt;</tt>.  Additionally, MSYS automatically
  1006                 detects binaries compiled for the MSYS environment and feeds them with the
  1007                 internal, Unix-style path names. If native Windows applications are called
  1008                 from within MSYS programs their path arguments are automatically converted
  1009                 back to Windows style path names with drive letters and backslashes as
  1010                 path separators. This may cause problems for Windows applications which
  1011                 use forward slashes as parameter separator (e.g. <tt>cl /nologo /I</tt>)
  1012                 because MSYS may wrongly <a href="http://mingw.org/wiki/Posix_path_conversion">
  1013                 replace such parameters by drive letters</a>.
  1014             </p>
  1015             <p>
  1016                 If you are using the MinGW/MSYS system you can use the default make
  1017                 version supplied by the environment.

  1092             Depending on the platform, the OpenJDK build process has some basic

  1094             Some of these are specific to a platform, some even specific to
  1095             an architecture.
  1096             Each dependency will have a set of ALT variables that can be set
  1097             to tell the makefiles where to locate the component.
  1098             In most cases setting these ALT variables may not be necessary
  1099             and the makefiles will find defaults on the system in standard

  1282                         The 32-bit OpenJDK Windows build requires

  1289                     <p> 
  1290                         Once the compiler is installed,

  1309                     For <b>X64</b>, the set up is much the same as 32 bit

  1311                     to set the compiler environment variables.
  1312                     Previously 64 bit builds had to use the 64 bit compiler in
  1313                     an unbundled Windows SDK but this is no longer necessary if

  1402                 Version 2.3 or newer of FreeType is required for building the OpenJDK.
  1403                 On Unix systems required files can be available as part of your
  1404                 distribution (while you still may need to upgrade them).
  1405                 Note that you need development version of package that 
  1406                 includes both FreeType library and header files.
  1407                 <p>
  1408                     You can always download latest FreeType version from the
  1409                     <a href="http://www.freetype.org" target="_blank">FreeType website</a>.
  1410                 <p>
  1411                     Makefiles will try to pick FreeType from /usr/lib and /usr/include.
  1412                     In case it is installed elsewhere you will need to set environment
  1413                     variables
  1414                     <tt><a href="#ALT_FREETYPE_LIB_PATH">ALT_FREETYPE_LIB_PATH</a></tt>
  1415                     and
  1416                     <tt><a href="#ALT_FREETYPE_HEADERS_PATH">ALT_FREETYPE_HEADERS_PATH</a></tt>
  1417                     to refer to place where library and header files are installed.
  1418                 <p>
  1419                     Building the freetype 2 libraries from scratch is also possible,
  1420                     however on Windows refer to the
  1421                     <a href="http://freetype.freedesktop.org/wiki/FreeType_DLL">
  1422                         Windows FreeType DLL build instructions</a>.
  1423                 <p>
  1424                     Note that by default FreeType is built with byte code hinting
  1425                     support disabled due to licensing restrictions.
  1426                     In this case, text appearance and metrics are expected to
  1427                     differ from Sun's official JDK build.

  1437                 <strong>Linux only:</strong>
  1438                 Version 0.9.1 or newer of the ALSA files are
  1439                 required for building the OpenJDK on Linux.
  1440                 These Linux files are usually available from an "alsa"
  1441                 of "libasound"
  1442                 development package, it's highly recommended that you try and use
  1443                 the package provided by the particular version of Linux that
  1444                 you are using.
  1445                 The makefiles will check this emit a sanity error if it is
  1446                 missing or the wrong version.
  1447                 <p>
  1448                     In particular, older Linux systems will likely not have the
  1449                     right version of ALSA installed, for example
  1450                     Redhat AS 2.1 U2 and SuSE 8.1 do not include a sufficiently
  1451                     recent ALSA distribution.
  1452                     On rpm-based systems, you can see if ALSA is installed by
  1453                     running this command:
  1454                 <pre>
  1455                     <tt>rpm -qa | grep alsa</tt>
  1456                 </pre>
  1457                 Both <tt>alsa</tt> and <tt>alsa-devel</tt> packages are needed.
  1458                 <p> 
  1459                     If your distribution does not come with ALSA, and you can't
  1460                     find ALSA packages built for your particular system,
  1461                     you can try to install the pre-built ALSA rpm packages from
  1462                     <a href="http://www.freshrpms.net/" target="_blank">
  1463                         <tt>www.freshrpms.net</tt></a>.
  1464                     Note that installing a newer ALSA could
  1465                     break sound output if an older version of ALSA was previously
  1466                     installed on the system, but it will enable JDK compilation.

  2035                     Most Linux builds should be possible with the system's

  2087         <blockquote>
  2088             A build can fail for any number of reasons. 
  2089             Most failures
  2090             are a result of trying to build in an environment in which all the
  2091             pre-build requirements have not been met. 
  2092             The first step in
  2093             troubleshooting a build failure is to recheck that you have satisfied
  2094             all the pre-build requirements for your platform.
  2095             Look for the check list of the platform you are building on in the

  2097             <p>
  2098                 You can validate your build environment by using the <tt>sanity</tt>
  2099                 target.
  2100                 Any errors listed
  2101                 will stop the build from starting, and any warnings may result in
  2102                 a flawed product build.
  2103                 We strongly encourage you to evaluate every
  2104                 sanity check warning and fix it if required, before you proceed
  2105                 further with your build.

  2115                         It may be necessary to disable the 'on access' or 'real time'

  2117                         This type of "real time" virus scanning can also slow down the

  2119                         Temporarily disabling the feature, or excluding the build

  2136                             The VM build tends to be CPU intensive (many C++ compiles),
  2137                             and the rest of the JDK will often be disk intensive.

  2154                         These warnings can occur when the clock on the build machine is out of
  2155                         sync with the timestamps on the source files. Other errors, apparently
  2156                         unrelated but in fact caused by the clock skew, can occur along with
  2157                         the clock skew warnings. These secondary errors may tend to obscure the
  2158                         fact that the true root cause of the problem is an out-of-sync clock.
  2159                         For example, an out-of-sync clock has been known to cause an old
  2160                         version of javac to be used to compile some files, resulting in errors
  2161                         when the pre-1.4 compiler ran across the new <tt>assert</tt> keyword
  2162                         in the 1.4 source code.

  2164                             If you see these warnings, reset the clock on the build
  2165                             machine, run "<tt><i>gmake</i> clobber</tt>" or delete the directory
  2166                             containing the build output, and restart the build from the beginning.
