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/

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. If you don't have a jdk6 installed, download and install a JDK 6 from
|
2007-12-01 00:00:00 +00:00
|
|
|
http://java.sun.com/javase/downloads/index.jsp
|
2010-12-22 20:25:52 +00:00
|
|
|
Set the environment variable ALT_BOOTDIR to the location of JDK 6.

|
|
|
2. Check the sanity of doing a build with your current system:
|
2007-12-01 00:00:00 +00:00
|
|
|
gnumake sanity
|
|
|
|
|
See README-builds.html if you run into problems.
|

|
|
|
3. Do a complete build of the OpenJDK:
|
2007-12-01 00:00:00 +00:00
|
|
|
gnumake all
|
|
|
|
|
The resulting JDK image should be found in build/*/j2sdk-image
|
|
|
|
|
|
2010-12-19 02:28:31 +00:00
|
|
|
where gnumake is GNU make 3.81 or newer, /usr/bin/make on Linux and
|
2007-12-01 00:00:00 +00:00
|
|
|
/usr/sfw/bin/gmake or /opt/sfw/bin/gmake on Solaris.
