7014634: By default, only build the product bits with a closed jdk build (like openjdk does)
Reviewed-by: katleman, cl, igor, trims
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.
11 This one root repository can be obtained with something like:
12 hg clone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7
13 To make sure you have all the nested repositories, you can run:
14 cd openjdk7 && sh ./get_source.sh
15 (This is identical to using the Mercurial Forest Extension command
16 'hg fclone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7').
17 People unfamiliar with Mercurial should read the first few chapters of
18 the Mercurial book: http://hgbook.red-bean.com/read/
20 See http://openjdk.java.net/ for more information about the OpenJDK.
22 Simple Build Instructions:
24 0. Get the necessary system software/packages installed on your system, see
25 http://hg.openjdk.java.net/jdk7/build/raw-file/tip/README-builds.html
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.
31 2. Check the sanity of doing a build with your current system:
32 gnumake sanity
33 See README-builds.html if you run into problems.
35 3. Do a complete build of the OpenJDK:
36 gnumake all
37 The resulting JDK image should be found in build/*/j2sdk-image
39 where gnumake is GNU make 3.81 or newer, /usr/bin/make on Linux and
40 /usr/sfw/bin/gmake or /opt/sfw/bin/gmake on Solaris.
