<h2><a name="introduction">Introduction</a></h2>
<blockquote>
This README file contains build instructions for the
<a href="http://openjdk.java.net" target="_blank">OpenJDK</a>.
Building the source code for the
OpenJDK
requires
a certain degree of technical expertise.
<!-- ====================================================== -->
<h3>!!!!!!!!!!!!!!! THIS IS A MAJOR RE-WRITE of this document. !!!!!!!!!!!!!</h3>
<blockquote>
Some Headlines:
<ul>
<li>
The build is now a "<code>configure && make</code>" style build
</li>
<li>
Any GNU make 3.81 or newer should work
</li>
<li>
The build should scale, i.e. more processors should
cause the build to be done in less wall-clock time
</li>
<li>
Nested or recursive make invocations have been significantly
reduced, as has the total fork/exec or spawning
of sub processes during the build
</li>
<li>
Windows MKS usage is no longer supported
</li>
<li>
Windows Visual Studio <code>vsvars*.bat</code> and
<code>vcvars*.bat</code> files are run automatically
</li>
<li>
Ant is no longer used when building the OpenJDK
</li>
<li>
Use of ALT_* environment variables for configuring the
build is no longer supported
</li>
</ul>

<h2><a name="hg">Use of Mercurial</a></h2>
<blockquote>
The OpenJDK sources are maintained with the revision control system
<a href="http://mercurial.selenic.com/wiki/Mercurial">Mercurial</a>.
If you are new to Mercurial, please see the
<a href="http://mercurial.selenic.com/wiki/BeginnersGuides">
Beginner Guides</a>
or refer to the <a href="http://hgbook.red-bean.com/">
Mercurial Book</a>.
The first few chapters of the book provide an excellent overview of
Mercurial, what it is and how it works.
<br>
For using Mercurial with the OpenJDK refer to the
<a href="http://openjdk.java.net/guide/repositories.html#installConfig">
Developer Guide: Installing and Configuring Mercurial</a>
section for more information.
<h3><a name="get_source">Getting the Source</a></h3>
<blockquote>
To get the entire set of OpenJDK Mercurial repositories
use the script <code>get_source.sh</code> located in the
root repository:
<blockquote>
<code>
hg clone http://hg.openjdk.java.net/jdk8/jdk8
<i>YourOpenJDK</i>
<br>
cd <i>YourOpenJDK</i>
<br>
bash ./get_source.sh
</code>
</blockquote>
Once you have all the repositories, keep in mind that each
repository is its own independent repository.
You can also re-run <code>./get_source.sh</code> anytime to
pull over all the latest changesets in all the repositories.
This set of nested repositories has been given the term
"forest" and there are various ways to apply the same
<code>hg</code> command to each of the repositories.
For example, the script <code>make/scripts/hgforest.sh</code>
can be used to repeat the same <code>hg</code>
command on every repository, e.g.
<blockquote>
<code>
cd <i>YourOpenJDK</i>
<br>
bash ./make/scripts/hgforest.sh status
</code>
</blockquote>
</blockquote>

<h3><a name="guidelines">Repository Source Guidelines</a></h3>
<blockquote>
There are some very basic guidelines:
<ul>
<li>
Use of whitespace in source files
(.java, .c, .h, .cpp, and .hpp files)
is restricted.
No TABs, no trailing whitespace on lines, and files
should not terminate in more than one blank line.
</li>
<li>
Files with execute permissions should not be added
to the source repositories.
</li>
<li>
All generated files need to be kept isolated from
the files
maintained or managed by the source control system.
The standard area for generated files is the top level
<code>build/</code> directory.
</li>
<li>
The default build process should be to build the product
and nothing else, in one form, e.g. a product (optimized),
debug (non-optimized, -g plus assert logic), or
fastdebug (optimized, -g plus assert logic).
</li>
<li>

<h2><a name="building">Building</a></h2>
<blockquote>
The very first step in building the OpenJDK is making sure the
system itself has everything it needs to do OpenJDK builds.
Once a system is setup, it generally doesn't need to be done again.
<br>
Building the OpenJDK is now done with running a
<a href="#configure"><code>configure</code></a>
script which will try and find and verify you have everything
you need, followed by running
<a href="#gmake"><code>make</code></a>, e.g.
<blockquote>
<b>
<code>
bash ./configure<br>
make all
</code>
</b>
</blockquote>
Where possible the <code>configure</code> script will attempt to located the
various components in the default locations or via component
specific variable settings.
When the normal defaults fail or components cannot be found,
additional <code>configure</code> options may be necessary to help <code>configure</code>
find the necessary tools for the build, or you may need to
re-visit the setup of your system due to missing software
packages.
<br>
<strong>NOTE:</strong> The <code>configure</code> script
file does not have
execute permissions and will need to be explicitly run with
<code>bash</code>,
see the <a href="#guidelines">source guidelines</a>.
<!-- ====================================================== -->
<hr>
<h3><a name="setup">System Setup</a></h3>
<blockquote>
Before even attempting to use a system to build the OpenJDK
there are some very basic system setups needed.
For all systems:
<ul>
<li>
Be sure the GNU make utility is version 3.81 or newer,
e.g. run "<code>make -version</code>"
</li>
<li>
Install a
<a name="bootjdk">Bootstrap JDK</a>.
All OpenJDK builds require access to a previously released
JDK called the <i>bootstrap JDK</i> or <i>boot JDK.</i>
The general rule is that the bootstrap JDK
must be an instance of the previous major
release of the JDK. In addition, there may be
a requirement to use a release at or beyond a
particular update level.
<br> <br>
<b><i>Building JDK 8 requires use of a version
of JDK 7 that is at Update 7 or newer. JDK 8
developers should not use JDK 8 as the boot
JDK, to ensure that JDK 8 dependencies are
not introduced into the parts of the system
that are built with JDK 7.</i></b>
<br> <br>
The JDK 7 binaries can be downloaded from Oracle's
<a href="http://www.oracle.com/technetwork/java/javase/downloads/index.html"
target="_blank">JDK 7 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 add its <code>bin</code> directory
to the <code>PATH</code> environment variable.
If <code>configure</code> has any issues finding this JDK, you may
need to use the <code>configure</code> option
<code>--with-boot-jdk</code>.
</li>
<li>
Ensure that GNU make, the Bootstrap JDK,
and the compilers are all
in your PATH environment variable
</li>
</ul>

<h4><a name="linux">Linux</a></h4>
<blockquote>
With Linux, try and favor the system packages over
building your own
or getting packages from other areas.
Most Linux builds should be possible with the system's
available packages.
<br>
Note that some Linux systems have a habit of pre-populating
your environment variables for you, for example <code>JAVA_HOME</code>
might get pre-defined for you to refer to the JDK installed on
your Linux system.
You will need to unset <code>JAVA_HOME</code>.
It's a good idea to run <code>env</code> and verify the
environment variables you are getting from the default system
settings make sense for building the OpenJDK.

<h4><a name="windows">Windows</a></h4>
<blockquote>
<h5><a name="toolkit">Windows Unix Toolkit</a></h5>
<blockquote>
Building on Windows requires a Unix-like environment, notably a
Unix-like shell.
There are several such environments available of which
<a href="http://www.cygwin.com/">Cygwin</a> and
<a href="http://www.mingw.org/wiki/MSYS">MinGW/MSYS</a> are
currently supported for
the OpenJDK build. One of the differences of these
systems from standard Windows tools is the way
they handle Windows path names, particularly path names which contain
spaces, backslashes as path separators and possibly drive letters.
Depending
on the use case and the specifics of each environment these path
problems can
be solved by a combination of quoting whole paths, translating
backslashes to
forward slashes, escaping backslashes with additional backslashes and
translating the path names to their
<a href="http://en.wikipedia.org/wiki/8.3_filename">
"8.3" version</a>.
<h6><a name="cygwin">CYGWIN</a></h6>
<blockquote>
CYGWIN is an open source, Linux-like environment which tries to emulate
a complete POSIX layer on Windows. It tries to be smart about path names
and can usually handle all kinds of paths if they are correctly quoted
or escaped although internally it maps drive letters <code><drive>:</code>
to a virtual directory <code>/cygdrive/<drive></code>.
<p>
You can always use the <code>cygpath</code> utility to map pathnames with spaces
or the backslash character into the <code>C:/</code> style of pathname
(called 'mixed'), e.g. <code>cygpath -s -m "<i>path</i>"</code>.
</p>
<p>
Note that the use of CYGWIN creates a unique problem with regards to
setting <a href="#path"><code>PATH</code></a>. Normally on Windows
the <code>PATH</code> variable contains directories
separated with the ";" character (Solaris and Linux use ":").
With CYGWIN, it uses ":", but that means that paths like "C:/path"
cannot be placed in the CYGWIN version of <code>PATH</code> and
instead CYGWIN uses something like <code>/cygdrive/c/path</code>
which CYGWIN understands, but only CYGWIN understands.
</p>
<p>
The OpenJDK build requires CYGWIN version 1.7.16 or newer.
Information about CYGWIN can
be obtained from the CYGWIN website at
<a href="http://www.cygwin.com" target="_blank">www.cygwin.com</a>.
</p>
<p>
By default CYGWIN doesn't install all the tools required for building
the OpenJDK.
Along with the default installation, you need to install
the following tools.

<h6><a name="msys">MinGW/MSYS</a></h6>
<blockquote>
MinGW ("Minimalist GNU for Windows") is a collection of free Windows
specific header files and import libraries combined with GNU toolsets that
allow one to produce native Windows programs that do not rely on any
3rd-party C runtime DLLs. MSYS is a supplement to MinGW which allows building
applications and programs which rely on traditional UNIX tools to
be present. Among others this includes tools like <code>bash</code>
and <code>make</code>.
See <a href="http://www.mingw.org/wiki/MSYS" target="_blank">MinGW/MSYS</a>
for more information.
<p>
Like Cygwin, MinGW/MSYS can handle different types of path formats. They
are internally converted to paths with forward slashes and drive letters
<code><drive>:</code> replaced by a virtual
directory <code>/<drive></code>. Additionally, MSYS automatically
detects binaries compiled for the MSYS environment and feeds them with the
internal, Unix-style path names. If native Windows applications are called
from within MSYS programs their path arguments are automatically converted
back to Windows style path names with drive letters and backslashes as
path separators. This may cause problems for Windows applications which
use forward slashes as parameter separator (e.g. <code>cl /nologo /I</code>)
because MSYS may wrongly <a href="http://mingw.org/wiki/Posix_path_conversion">
replace such parameters by drive letters</a>.
</p>
<p>
In addition to the tools which will be installed
by default, you have
to manually install the
<code>msys-zip</code> and
<code>msys-unzip</code> packages.
This can be easily done with the MinGW command line installer:
<blockquote>
<code>mingw-get.exe install msys-zip</code>
<br>
<code>mingw-get.exe install msys-unzip</code>
</blockquote>
</blockquote>
</blockquote>
<h5><a name="vs2010">Visual Studio 2010 Compilers</a></h5>
<blockquote>
<p>
The 32-bit and 64-bit OpenJDK Windows build requires
Microsoft Visual Studio C++ 2010 (VS2010) Professional
Edition or Express compiler.
The compiler and other tools are expected to reside
in the location defined by the variable
<code>VS100COMNTOOLS</code> which
is set by the Microsoft Visual Studio installer.
</p>
<p>
Only the C++ part of VS2010 is needed.
Try to let the installation go to the default
install directory.
Always reboot your system after installing VS2010.
The system environment variable VS100COMNTOOLS
should be
set in your environment.
</p>
<p>
Make sure that TMP and TEMP are also set
in the environment
and refer to Windows paths that exist,
like <code>C:\temp</code>,
not <code>/tmp</code>, not <code>/cygdrive/c/temp</code>,
and not <code>C:/temp</code>.
<code>C:\temp</code> is just an example,
it is assumed that this area is
private to the user, so by default
after installs you should
see a unique user path in these variables.

<h3><a name="configure">Configure</a></h3>
<blockquote>
The basic invocation of the <code>configure</code> script
looks like:
<blockquote>
<b><code>bash ./configure [<i>options</i>]</code></b>
</blockquote>
This will create an output directory containing the
"configuration" and setup an area for the build result.
This directory typically looks like:
<blockquote>
<b><code>build/linux-x64-normal-server-release</code></b>
</blockquote>
<code>configure</code> will try to figure out what system you are running on
and where all necessary build components are.
If you have all prerequisites for building installed,
it should find everything.
If it fails to detect any component automatically,
it will exit and inform you about the problem.
When this happens, read more below in

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.
By default an empty cacerts file is provided and that should be
fine for most JDK developers.
