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

 236             These same sources do indeed build on many more systems than the
 237             above older generation systems, again the above is just a minimum.

 239             Compilation problems with newer or different C/C++ compilers is a
 240             common problem.
 241             Similarly, compilation problems related to changes to the
 242                 <tt>/usr/include</tt> or system header files is also a
 243             common problem with newer or unreleased OS versions.
 244             Please report these types of problems as bugs so that they
 245             can be dealt with accordingly.

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

 577                         will attempt to locate these zip bundles from the directory

 582                         Once the sources are made available, the population will not

 588                         is to NOT download these bundles from the public http site.
 589                         In general, doing downloads
 590                         during the build process is not advised, it creates too much

 592                         However, you can use <tt>make ALLOW_DOWNLOADS=true</tt> to
 593                         tell the ant script that the download of the zip bundle is
 594                         acceptable.

 598                         source bundles would be to download them once, place them
 599                         in a directory outside the repositories, and then set
 600                         <tt><a href="#ALT_DROPS_DIR">ALT_DROPS_DIR</a></tt> to refer
 601                         to that directory.
 602                         These drop bundles do change occasionally, so the newer
 603                         bundles may need to be added to this area from time to time.

 613             is done with a <a href="#gmake">GNU <tt>make</tt></a> command line
 614             and various
 615             environment or make variable settings that direct the makefile rules
 616             to where various components have been installed.
 617             Where possible the makefiles will attempt to located the various
 618             components in the default locations or any component specific 
 619             variable settings.
 620             When the normal defaults fail or components cannot be found,
 621             the various
 622             <tt>ALT_*</tt> variables (alternates)
 623             can be used to help the makefiles locate components.
 624             <p>
 625                 Refer to the bash/sh/ksh setup file
 626                 <tt>jdk/make/jdk_generic_profile.sh</tt>
 627                 if you need help in setting up your environment variables.
 628                 A build could be as simple as:
 629             <blockquote>
 630                 <pre><tt>
 631                 bash

 636             <p>
 637                 Of course ksh or sh would work too.
 638                 But some customization will probably be necessary.
 639                 The <tt>sanity</tt> rule will make some basic checks on build

 760             <p> 
 761                 The build will use the tools contained in

 763                 <tt>/usr/bin</tt>
 764                 of a standard installation of the Linux operating environment.

 767             <p>
 768                 Note that some Linux systems have a habit of pre-populating

 770                 might get pre-defined for you to refer to the JDK installed on
 771                 your Linux system.
 772                 You will need to unset <tt>JAVA_HOME</tt>.
 773                 It's a good idea to run <tt>env</tt> and verify the
 774                 environment variables you are getting from the default system
 775                 settings make sense for building the
 776                 OpenJDK.

 817                 <tt>amd64</tt>.
 818                 An additional 7 GB of free disk space is needed

 887         <blockquote>
 888             <strong>Windows:</strong>
 889             Note that GNU make is a historic utility and is based very
 890             heavily on shell scripting, so it does not tolerate the Windows habit
 891             of having spaces in pathnames or the use of the <tt>\</tt>characters in pathnames.
 892             Luckily on most Windows systems, you can use <tt>/</tt>instead of \, and
 893             there is always a 'short' pathname without spaces for any path that 
 894             contains spaces.
 895             Unfortunately, this short pathname can be somewhat dynamic and the
 896             formula is difficult to explain.
 897             You can use <tt>cygpath</tt> utility to map pathnames with spaces
 898             or the <tt>\</tt>character into the <tt>C:/</tt> style of pathname
 899             (called 'mixed'), e.g.
 900             <tt>cygpath -s -m "<i>path</i>"</tt>.
 901             <p>
 902                 The makefiles will try to translate any pathnames supplied
 903                 to it into the <tt>C:/</tt> style automatically.
 904             <p>
 905                 Note that use of CYGWIN creates a unique problem with regards to
 906                 setting <a href="#path"><tt>PATH</tt></a>. Normally on Windows
 907                 the <tt>PATH</tt> variable contains directories
 908                 separated with the ";" character (Solaris and Linux uses ":").
 909                 With CYGWIN, it uses ":", but that means that paths like "C:/path"
 910                 cannot be placed in the CYGWIN version  of <tt>PATH</tt> and
 911                 instead CYGWIN uses something like <tt>/cygdrive/c/path</tt>
 912                 which CYGWIN understands, but only CYGWIN understands.
 913                 So be careful with paths on Windows.

 960             Each dependency will have a set of ALT variables that can be set

 962             In most cases setting these ALT variables may not be necessary

1026                     http://en.wikipedia.org/wiki/Certificate_Authority</a>
1027                 for a better understanding of the Certificate Authority (CA).
1028                 A certificates file named "cacerts"
1029                 represents a system-wide keystore with CA certificates. 
1030                 In JDK and JRE
1031                 binary bundles, the "cacerts" file contains root CA certificates from
1032                 several public CAs (e.g., VeriSign, Thawte, and Baltimore).
1033                 The source contain a cacerts file
1034                 without CA root certificates. 
1035                 Formal JDK builders will need to secure
1036                 permission from each public CA and include the certificates into their
1037                 own custom cacerts file. 
1038                 Failure to provide a populated cacerts file
1039                 will result in verification errors of a certificate chain during runtime.
1040                 The variable 
1041                 <tt><a href="#ALT_CACERTS_FILE">ALT_CACERTS_FILE</a></tt>
1042                 can be used to override the default location of the
1043                 cacerts file that will get placed in your build.
1044                 By default an empty cacerts file is provided and that should be
1045                 fine for most JDK developers.

1146                         The 32-bit OpenJDK Windows build requires

1148                         Edition or Express compiler.
1149                         The compiler and other tools are expected to reside

1153                     <p> 
1154                         Once the compiler is installed,

1261                 Version 2.3 or newer of FreeType is required for building the OpenJDK.
1262                 On Unix systems required files can be available as part of your
1263                 distribution (while you still may need to upgrade them).
1264                 Note that you need development version of package that 
1265                 includes both FreeType library and header files.

1269                 <p>
1270                     Makefiles will try to pick FreeType from /usr/lib and /usr/include.
1271                     In case it is installed elsewhere you will need to set environment
1272                     variables
1273                     <tt><a href="#ALT_FREETYPE_LIB_PATH">ALT_FREETYPE_LIB_PATH</a></tt>

1276                     to refer to place where library and header files are installed.
1277                 <p>
1278                     Building the freetype 2 libraries from scratch is also possible,
1279                     however on Windows refer to the

1282                 <p>
1283                     Note that by default FreeType is built with byte code hinting
1284                     support disabled due to licensing restrictions.
1285                     In this case, text appearance and metrics are expected to
1286                     differ from Sun's official JDK build.

1296                 <strong>Linux only:</strong>
1297                 Version 0.9.1 or newer of the ALSA files are
1298                 required for building the OpenJDK on Linux.
1299                 These Linux files are usually available from an "alsa"
1300                 of "libasound"
1301                 development package, it's highly recommended that you try and use
1302                 the package provided by the particular version of Linux that
1303                 you are using.
1304                 The makefiles will check this emit a sanity error if it is
1305                 missing or the wrong version.
1306                 <p>
1307                     In particular, older Linux systems will likely not have the
1308                     right version of ALSA installed, for example
1309                     Redhat AS 2.1 U2 and SuSE 8.1 do not include a sufficiently
1310                     recent ALSA distribution.
1311                     On rpm-based systems, you can see if ALSA is installed by
1312                     running this command:
1313                 <pre>
1314                     <tt>rpm -qa | grep alsa</tt>
1315                 </pre>
1316                 Both <tt>alsa</tt> and <tt>alsa-devel</tt> packages are needed.
1317                 <p> 
1318                     If your distribution does not come with ALSA, and you can't
1319                     find ALSA packages built for your particular system,
1320                     you can try to install the pre-built ALSA rpm packages from
1321                     <a href="http://www.freshrpms.net/" target="_blank">
1322                         <tt>www.freshrpms.net</tt></a>.
1323                     Note that installing a newer ALSA could
1324                     break sound output if an older version of ALSA was previously
1325                     installed on the system, but it will enable JDK compilation.

1787                             When cross-compiling we skip execution of any demos etc that may be built, and

1806                             to produce other parts of the build. Normally the primary C compiler is used
1807                             to do this, but when cross-compiling that would be the cross-compiler and the

1877                     Most Linux builds should be possible with the system's

1891                             Always reboot your system after installing VS2010.
1892                             The system environment variable VS100COMNTOOLS should be
1893                             set in your environment.

1899                             <tt>C:\temp</tt> is just an example, it is assumed that this area is
1900                             private to the user, so by default after installs you should
1901                             see a unique user path in these variables.

1929         <blockquote>
1930             A build can fail for any number of reasons. 
1931             Most failures
1932             are a result of trying to build in an environment in which all the
1933             pre-build requirements have not been met. 
1934             The first step in
1935             troubleshooting a build failure is to recheck that you have satisfied
1936             all the pre-build requirements for your platform.
1937             Look for the check list of the platform you are building on in the
1938             <a href="#contents">Table of Contents</a>.
1939             <p>
1940                 You can validate your build environment by using the <tt>sanity</tt>
1941                 target.
1942                 Any errors listed
1943                 will stop the build from starting, and any warnings may result in
1944                 a flawed product build.
1945                 We strongly encourage you to evaluate every
1946                 sanity check warning and fix it if required, before you proceed
1947                 further with your build.

1955                         Some virus scanning software has been known to corrupt the

1957                         It may be necessary to disable the 'on access' or 'real time'
1958                         virus scanning features to prevent this corruption.
1959                         This type of "real time" virus scanning can also slow down the
1960                         build process significantly.
1961                         Temporarily disabling the feature, or excluding the build
1962                         output directory may be necessary to get correct and faster builds.

1974                             Creating the javadocs can be very slow, if you are running

1977                             Faster hardware and more RAM always helps too.
1978                             The VM build tends to be CPU intensive (many C++ compiles),
1979                             and the rest of the JDK will often be disk intensive.

1989                         <blockquote>

1996                         These warnings can occur when the clock on the build machine is out of
1997                         sync with the timestamps on the source files. Other errors, apparently
1998                         unrelated but in fact caused by the clock skew, can occur along with
1999                         the clock skew warnings. These secondary errors may tend to obscure the
2000                         fact that the true root cause of the problem is an out-of-sync clock.
2001                         For example, an out-of-sync clock has been known to cause an old
2002                         version of javac to be used to compile some files, resulting in errors
2003                         when the pre-1.4 compiler ran across the new <tt>assert</tt> keyword
2004                         in the 1.4 source code.
2005                         <p>
2006                             If you see these warnings, reset the clock on the build
2007                             machine, run "<tt><i>gmake</i> clobber</tt>" or delete the directory
2008                             containing the build output, and restart the build from the beginning.
