README:
This file should be located at the top of the OpenJDK Mercurial repository
forest. This top or enclosing repository will include a "make" directory,
and a Makefile at the very top of the repository.
It should also include the 6 repositories: "jdk", "hotspot", "langtools",
"corba", "jaxws" and "jaxp".
This file should be located at the top of the OpenJDK Mercurial root
repository. This root repository will include a "make" directory,
and a Makefile for building the entire OpenJDK.
A full OpenJDK repository set (forest) should also include the following
6 nested repositories:
"jdk", "hotspot", "langtools", "corba", "jaxws" and "jaxp".
There are also several source downloads for the jax* repositories that
will be needed.
This one root repository can be obtained with something like:
hg clone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7
To make sure you have all the nested repositories, you can run:
cd openjdk7 && sh ./get_source.sh
(This is identical to using the Mercurial Forest Extension command
'hg fclone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7').
People unfamiliar with Mercurial should read the first few chapters of
the Mercurial book: http://hgbook.red-bean.com/read/
See http://openjdk.java.net/ for more information about the OpenJDK.
Simple Build Instructions:
0. Get the necessary system software/packages installed on your system, see
http://hg.openjdk.java.net/jdk7/build/raw-file/tip/README-builds.html
1. Download and install a JDK 6 from
1. If you don't have a jdk6 installed, download and install a JDK 6 from
http://java.sun.com/javase/downloads/index.jsp
Set the environment variable ALT_BOOTDIR to the location of this JDK 6.
Set the environment variable ALT_BOOTDIR to the location of JDK 6.
2. Download and install the Binary Plugs for the most recent JDK7 from
http://download.java.net/openjdk/jdk7/
Set the environment variable ALT_BINARY_PLUGS_PATH to the location of
these binary plugs.
3. Check the sanity of doing a build with the current machine:
2. Check the sanity of doing a build with your current system:
gnumake sanity
See README-builds.html if you run into problems.
4. Do a complete build of the jdk:
3. Do a complete build of the OpenJDK:
gnumake all
The resulting JDK image should be found in build/*/j2sdk-image
