11N/A This file often describes specific requirements for what we call the
47N/A "minimum build environments" (MBE) for this
47N/A specific release of the JDK,
11N/A Building with the MBE will generate the most compatible
11N/A bits that install on, and run correctly on, the most variations
11N/A of the same base OS and hardware architecture.
11N/A These usually represent what is often called the
11N/A least common denominator platforms.
11N/A It is understood that most developers will NOT be using these
11N/A specific platforms, and in fact creating these specific platforms
11N/A may be difficult due to the age of some of this software.

47N/A above older generation systems, again the above is just a minimum.

11N/A When the normal defaults fail or components cannot be found,
11N/A <

11N/A can be used to help the makefiles locate components.

11N/A A build could be as simple as:

11N/A Of course ksh or sh would work too.
11N/A But some customization will probably be necessary.

11N/A Once a machine is setup to build the OpenJDK,
11N/A the steps to create the build are fairly simple.
11N/A The various ALT settings can either be made into variables
11N/A or can be supplied on the
11N/A <
a href="#gmake"><
tt><
i>gmake</
i></

11N/A <

11N/A [ARCH_DATA_MODEL=<
i>32 or 64</
i>]
11N/A [other "ALT_" overrides]
11N/A <
li>Start the build with the command:
11N/A [ARCH_DATA_MODEL=<
i>32 or 64</
i>]
11N/A [ALT_OUTPUTDIR=<
i>output_directory</
i>]
11N/A [other "ALT_" overrides]
11N/A <
strong>Solaris:</
strong>
11N/A Note that ARCH_DATA_MODEL is really only needed on Solaris to
11N/A indicate you want to built the 64-bit version.
11N/A And before the Solaris 64-bit binaries can be used, they
11N/A must be merged with the binaries from a separate 32-bit build.
11N/A The merged binaries may then be used in either 32-bit or 64-bit mode, with
11N/A the selection occurring at runtime
11N/A with the <
tt>-d32</
tt> or <
tt>-d64</
tt> options.
11N/A <!-- ------------------------------------------------------ --> 11N/A <

11N/A When the build is completed, you should see the generated
11N/A binaries and associated files in the <
tt>j2sdk-image</
tt>
11N/A directory in the output directory.
11N/A The default output directory is
11N/A <

11N/A A build can fail for any number of reasons.
11N/A are a result of trying to build in an environment in which all the
11N/A pre-build requirements have not been met.
11N/A troubleshooting a build failure is to recheck that you have satisfied
11N/A all the pre-build requirements for your platform.
11N/A Look for the check list of the platform you are building on in the
11N/A <
a href="#contents">Table of Contents</
a>.
11N/A You can validate your build environment by using the <
tt>sanity</
tt>
11N/A will stop the build from starting, and any warnings may result in
11N/A a flawed product build.
11N/A We strongly encourage you to evaluate every
11N/A sanity check warning and fix it if required, before you proceed
11N/A further with your build.
11N/A Some of the more common problems with builds are briefly described
11N/A below, with suggestions for remedies.
11N/A <
b>Slow Builds:</
b>
11N/A If your build machine seems to be overloaded from too many
11N/A simultaneous C++ compiles, try setting the <
tt>HOTSPOT_BUILD_JOBS</
tt>
11N/A variable to <
tt>1</
tt> (if you're using a multiple CPU
11N/A machine, setting it to more than the the number of CPUs is probably
11N/A Creating the javadocs can be very slow, if you are running
11N/A javadoc, consider skipping that step.
11N/A Faster hardware and more RAM always helps too.
11N/A The VM build tends to be CPU intensive (many C++ compiles),
11N/A and the rest of the JDK will often be disk intensive.
11N/A Faster compiles are possible using a tool called
11N/A <
b>File time issues:</
b>
11N/A If you see warnings that refer to file time stamps,
e.g. 11N/A <
i>Warning message:</
i><
tt> File `xxx' has modification time in
11N/A <
i>Warning message:</
i> <
tt> Clock skew detected. Your build may
11N/A be incomplete.</
tt>
11N/A These warnings can occur when the clock on the build machine is out of
11N/A sync with the timestamps on the source files. Other errors, apparently
11N/A unrelated but in fact caused by the clock skew, can occur along with
11N/A the clock skew warnings. These secondary errors may tend to obscure the
11N/A fact that the true root cause of the problem is an out-of-sync clock.
11N/A For example, an out-of-sync clock has been known to cause an old
11N/A version of javac to be used to compile some files, resulting in errors
11N/A when the pre-1.4 compiler ran across the new <
tt>assert</
tt> keyword
11N/A in the 1.4 source code.
11N/A If you see these warnings, reset the clock on the build
11N/A machine, run "<
tt><
i>gmake</
i> clobber</
tt>" or delete the directory
11N/A containing the build output, and restart the build from the beginning.
11N/A <
b>Error message: <
tt>Trouble writing out table to disk</
tt></
b>
11N/A Increase the amount of swap space on your build machine.
11N/A <
b>Error Message: <
tt>libstdc++ not found:</
tt></
b>
11N/A This is caused by a missing libstdc++.a library.
11N/A This is installed as part of a specific package
47N/A By default some 64-bit Linux versions (
e.g. Fedora)
47N/A only install the 64-bit version of the libstdc++ package.
11N/A Various parts of the JDK build require a static
11N/A link of the C++ runtime libraries to allow for maximum
11N/A portability of the built images.
11N/A <
b>Error Message: <
tt>cannot restore segment prot after reloc</
tt></
b>
11N/A This is probably an issue with SELinux (See
11N/A Parts of the VM is built without the <
tt>-fPIC</
tt> for
11N/A performance reasons.
11N/A To completely disable SELinux:
