| 1 | README:
|
|---|
| 2 | This file should be located at the top of the OpenJDK Mercurial root
|
|---|
| 3 | repository. This root repository will include a "make" directory,
|
|---|
| 4 | and a Makefile for building the entire OpenJDK.
|
|---|
| 5 | A full OpenJDK repository set (forest) should also include the following
|
|---|
| 6 | 6 nested repositories:
|
|---|
| 7 | "jdk", "hotspot", "langtools", "corba", "jaxws" and "jaxp".
|
|---|
| 8 | There are also several source downloads for the jax* repositories that
|
|---|
| 9 | will be needed.
|
|---|
| 10 |
|
|---|
| 11 | This one root repository can be obtained with something like:
|
|---|
| 12 | hg clone http://hg.openjdk.java.net/jdk6/jdk6 openjdk6
|
|---|
| 13 | To make sure you have all the nested repositories, you can run:
|
|---|
| 14 | cd openjdk6 && sh ./get_source.sh
|
|---|
| 15 | (This is identical to using the Mercurial Forest Extension command
|
|---|
| 16 | 'hg fclone http://hg.openjdk.java.net/jdk6/jdk6 openjdk6').
|
|---|
| 17 | People unfamiliar with Mercurial should read the first few chapters of
|
|---|
| 18 | the Mercurial book: http://hgbook.red-bean.com/read/
|
|---|
| 19 |
|
|---|
| 20 | See http://openjdk.java.net/ for more information about the OpenJDK.
|

|
|---|
| 22 | Simple Build Instructions:
|
|---|
| 23 |
|
|---|
| 24 | 0. Get the necessary system software/packages installed on your system, see
|
|---|
| 25 | http://hg.openjdk.java.net/jdk6/build/raw-file/tip/README-builds.html
|
|---|
| 26 |
|
|---|
| 27 | 1. If you don't have a jdk6 installed, download and install a JDK 6 from
|
|---|
| 28 | http://java.sun.com/javase/downloads/index.jsp
|
|---|
| 29 | Set the environment variable ALT_BOOTDIR to the location of JDK 6.
|
|---|
| 30 |
|
|---|
| 31 | 2. Check the sanity of doing a build with your current system:
|
|---|
| 32 | make sanity
|
|---|
| 33 | See README-builds.html if you run into problems.
|
|---|
| 34 |
|
|---|
| 35 | 3. Do a complete build of the OpenJDK:
|
|---|
| 36 | make all
|
|---|
| 37 | The resulting JDK image should be found in build/*/j2sdk-image
|
|---|
| 38 |
|
|---|
| 39 | where make is GNU make 3.81 or newer, /usr/bin/make on Linux usually
|
|---|
| 40 | is 3.81 or newer.
|
|---|
| 41 |
|
|---|
| 42 | Complete details are available in README-builds.html.
