<h2><a name="MBE">Minimum Build Environments</a></h2>
<blockquote>
<p>
This file often describes specific requirements for what we call the
"minimum build environments" (MBE) for the JDK.
Building with the MBE will generate the most compatible
bits that install on, and run correctly on, the most variations
of the same base OS and hardware architecture.
These usually represent what is often called the
least common denominator platforms.
It is understood that most developers will NOT be using these
specific platforms, and in fact creating these specific platforms
may be difficult due to the age of some of this software.
<p>
<p>
The minimum OS and C/C++ compiler versions needed for building the
OpenJDK:

<h2><a name="building">Build Information</a></h2>
<blockquote>
<p>
Building the
OpenJDK
is done with a <tt><i>gmake</i></tt>
command line and various
environment or make variable settings that direct the make rules
to where various components have been installed.
Where possible the makefiles will attempt to located the various
components in the default locations or any component specific
variable settings.
When the normal defaults fail or components cannot be found,
the various
<tt>ALT_*</tt> variables (alternates)
can be used to help the makefiles locate components.
<p>
Refer to the bash/sh/ksh setup file
<tt>jdk/make/jdk_generic_profile.sh</tt>
if you need help in setting up your environment variables.
A build could be as simple as:
<blockquote>
<pre><tt>
bash
. jdk/make/jdk_generic_profile.sh
<i>gmake</i> sanity && <i>gmake</i>
</tt></pre>
</blockquote>
<p>
Of course ksh or sh would work too.
But some customization will probably be necessary.
The <tt>sanity</tt> rule will make some basic checks on build
dependencies and generate appropriate warning messages
regarding missing, out of date, or newer than expected components
found on your system.

<h3><a name="gmake">GNU make (<tt><i>gmake</i></tt>)</a></h3>
<blockquote>
<p>
The Makefiles in the
OpenJDK
are only valid when used with the
GNU version of the utility command <tt>make</tt>
(<tt><i>gmake</i></tt>).
A few notes about using GNU make:
<ul>
<li>
In general, you need GNU make version 3.78.1 or newer.
</li>
<li>
Place the location of the GNU make binary in the <tt>PATH</tt>.
</li>
<li>
<strong>Linux:</strong>
The <tt>/usr/bin/make</tt> command should work fine for you.
</li>
<li>
<strong>Solaris:</strong>
Do NOT use <tt>/usr/bin/make</tt> on Solaris.
If your Solaris system has the software
from the Solaris Companion CD installed,
you should use <tt>gmake</tt>
which will be located in either the <tt>/opt/sfw/bin</tt> or
<tt>/usr/sfw/bin</tt> directory.
</li>
<li>
<strong>Windows:</strong>
Make sure you start your build inside a bash/sh/ksh shell.
<br>
<b>WARNING:</b> Watch out for make version 3.81, it may
not work due to a lack of support for drive letter paths
like <tt>C:/</tt>. Use a 3.80 version, or find a newer
version that has this problem fixed.
</li>
</ul>
<p>
Information on GNU make, and access to ftp download sites, are
available on the
<a href="http://www.gnu.org/software/make/make.html">

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

<h3><a name="dependencies">Build Dependencies</a></h3>
<blockquote>
<p>
Depending on the platform, the
OpenJDK
build process has some basic
dependencies on components not part of the
OpenJDK
sources.
Some of these are specific to a platform, some even specific to
an architecture.
Each dependency will have a set of ALT variables that can be set
to tell the makefiles where to locate the component.
In most cases setting these ALT variables may not be necessary
and the makefiles will find defaults on the system in standard
install locations or through component specific variables.
<h4><a name="bootjdk">Bootstrap JDK</a></h4>
<blockquote>
<p>
All
OpenJDK
builds require access to the previously released
JDK 6, this is often called a bootstrap JDK.
The JDK 6 binaries can be downloaded from Sun's
<a href="http://java.sun.com/javase/1.6.0/download.html">JDK 6 download site</a>.
For build performance reasons
is very important that this bootstrap JDK be made available on the
local disk of the machine doing the build.
You should always set
<tt><a href="#ALT_BOOTDIR">ALT_BOOTDIR</a></tt>
to point to the location of
the bootstrap JDK installation, this is the directory pathname
that contains a <tt>bin, lib, and include</tt>
It's also a good idea to also place its <tt>bin</tt> directory
in the <tt>PATH</tt> environment variable, although it's
not required.
<p>
<strong>Solaris:</strong>
Some pre-installed JDK images may be available to you in the
directory <tt>/usr/jdk/instances</tt>.
If you don't set
<tt><a href="#ALT_BOOTDIR">ALT_BOOTDIR</a></tt>
the makefiles will look in that location for a JDK it can use.
</blockquote>
<h4><a name="binaryplugs">Binary Plugs</a></h4>
<blockquote>
<p>
Not all of the source code that makes up the JDK is available
under an open-source license.
In order to build an OpenJDK binary from source code,
you must first download and install the appropriate
binary plug bundles from the OpenJDK Download area.
During the OpenJDK build process these "binary plugs"
for the encumbered components will be copied into your
resulting OpenJDK binary build image.
These binary plug files are only for the purpose of
building an OpenJDK binary.
Download the Binary Plugs by selecting the <b>Downloads</b>
link at
<a href="http://openjdk.java.net/">the OpenJDK site</a>,
install the bundle,
and make sure you set
<tt><a href="#ALT_BINARY_PLUGS_PATH">ALT_BINARY_PLUGS_PATH</a></tt>
to the root of this installation.
</blockquote>
<h4><a name="cacerts">Certificate Authority File (cacert)</a></h4>
<blockquote>
<p>
See <a href="http://en.wikipedia.org/wiki/CAcert">
www.wikipedia.org/wiki/CAcert</a>
for a better understanding of the Certificate Authority (CA).
A certificates file named "cacerts"
represents a system-wide keystore with CA certificates.
In JDK and JRE
binary bundles, the "cacerts" file contains root CA certificates from
several public CAs (e.g., VeriSign, Thawte, and Baltimore).
The source contain a cacerts file
without CA root certificates.
Formal JDK builders will need to secure
permission from each public CA and include the certificates into their
own custom cacerts file.
Failure to provide a populated cacerts file
will result in verification errors of a certificate chain during runtime.
The variable
<tt><a href="#ALT_CACERTS_FILE">ALT_CACERTS_FILE</a></tt>
can be used to override the default location of the

<h2><a name="creating">Creating the Build</a></h2>
<blockquote>
<p>
Once a machine is setup to build the
OpenJDK,
the steps to create the
build are fairly simple.
The various ALT settings can either be made into variables
or can be supplied on the
<a href="#gmake"><tt><i>gmake</i></tt></a>
command.
<p>
<ol>
<li>Use the sanity rule to double check all the ALT settings:
<blockquote>
<tt>
<i>gmake</i>
sanity
[ARCH_DATA_MODEL=<i>32 or 64</i>]
[other "ALT_" overrides]
</tt>
</blockquote>
</li>
<li>Start the build with the command:
<blockquote>
<tt>
<i>gmake</i>
[ARCH_DATA_MODEL=<i>32 or 64</i>]
[ALT_OUTPUTDIR=<i>output_directory</i>]
[other "ALT_" overrides]
</tt>
</blockquote>
</li>
</ol>
<p>
<strong>Solaris:</strong>
Note that ARCH_DATA_MODEL is really only needed on Solaris to
indicate you want to built the 64-bit version.
And before the Solaris 64-bit binaries can be used, they
must be merged with the binaries from a separate 32-bit build.
The merged binaries may then be used in either 32-bit or 64-bit mode, with
the selection occurring at runtime
with the <tt>-d32</tt> or <tt>-d64</tt> options.

<h2><a name="troubleshooting">Troubleshooting</a></h2>
<blockquote>
<p>
A build can fail for any number of reasons.
Most failures
are a result of trying to build in an environment in which all the
pre-build requirements have not been met.
The first step in
troubleshooting a build failure is to recheck that you have satisfied
all the pre-build requirements for your platform.
Look for the check list of the platform you are building on in the
<a href="#contents">Table of Contents</a>.
<p>
You can validate your build environment by using the <tt>sanity</tt>
target.
Any errors listed
will stop the build from starting, and any warnings may result in
a flawed product build.
We strongly encourage you to evaluate every
sanity check warning and fix it if required, before you proceed
further with your build.
<p>
Some of the more common problems with builds are briefly described
below, with suggestions for remedies.
<ul>
<li>
<b>Slow Builds:</b>
<blockquote>
<p>
If your build machine seems to be overloaded from too many
simultaneous C++ compiles, try setting the <tt>HOTSPOT_BUILD_JOBS</tt>
variable to <tt>1</tt> (if you're using a multiple CPU
machine, setting it to more than the the number of CPUs is probably
not a good idea).
<p>
Creating the javadocs can be very slow, if you are running
javadoc, consider skipping that step.
<p>
Faster hardware and more RAM always helps too.
The VM build tends to be CPU intensive (many C++ compiles),
and the rest of the JDK will often be disk intensive.
<p>
Faster compiles are possible using a tool called
<a href="http://ccache.samba.org/">ccache</a>.
</blockquote>
</li>
<li>
<b>File time issues:</b>
<blockquote>
<p>
If you see warnings that refer to file time stamps, e.g.
<blockquote>
<i>Warning message:</i><tt> File `xxx' has modification time in
the future.</tt>
<br>
<i>Warning message:</i> <tt> Clock skew detected. Your build may
be incomplete.</tt>
</blockquote>
<p>
These warnings can occur when the clock on the build machine is out of
sync with the timestamps on the source files. Other errors, apparently
unrelated but in fact caused by the clock skew, can occur along with
the clock skew warnings. These secondary errors may tend to obscure the
fact that the true root cause of the problem is an out-of-sync clock.
For example, an out-of-sync clock has been known to cause an old
version of javac to be used to compile some files, resulting in errors
when the pre-1.4 compiler ran across the new <tt>assert</tt> keyword
in the 1.4 source code.
<p>
If you see these warnings, reset the clock on the build
machine, run "<tt><i>gmake</i> clobber</tt>" or delete the directory
containing the build output, and restart the build from the beginning.
</blockquote>
</li>
<li>
<b>Error message: <tt>Trouble writing out table to disk</tt></b>
<blockquote>
<p>
Increase the amount of swap space on your build machine.
</blockquote>
</li>
<li>
<b>Error Message: <tt>libstdc++ not found:</tt></b>
<blockquote>
This is caused by a missing libstdc++.a library.
This is installed as part of a specific package
(e.g. libstdc++.so.devel.386).
By default some 64bit Linux versions (e.g. Fedora)
only install the 64bit version of the libstdc++ package.
Various parts of the JDK build require a static
link of the C++ runtime libraries to allow for maximum
portability of the built images.
</blockquote>
</li>
<li>
<b>Error Message: <tt>cannot restore segment prot after reloc</tt></b>
<blockquote>
This is probably an issue with SELinux (See
<a href="http://en.wikipedia.org/wiki/SELinux">http://en.wikipedia.org/wiki/SELinux</a>).
Parts of the VM is built without the <tt>-fPIC</tt> for
performance reasons.
<p>
To completely disable SELinux:
<ol><tt>
<li>$ su root</li>
<li># system-config-securitylevel</li>
<li>In the window that appears, select the SELinux tab</li>
<li>Disable SELinux</li>
</ol></tt>
<p>
Alternatively, instead of completely disabling it you could
disable just this one check.
<ol><tt>
<li>Select System->Administration->SELinux Management</li>
<li>In the SELinux Management Tool which appears,
select "Boolean" from the menu on the left</li>
<li>Expand the "Memory Protection" group</li>
<li>Check the first item, labeled
"Allow all unconfined executables to use libraries requiring text relocation ..."</li>
</ol></tt>
