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:
13 hg clone http://hg.openjdk.java.net/jdk8/jdk8 openjdk8
15 To make sure you have all the nested repositories, you can run the
16 get_source.sh script located in the same respository as this file:
18 cd openjdk8 && sh ./get_source.sh
20 People unfamiliar with Mercurial should read the first few chapters of
21 the Mercurial book: http://hgbook.red-bean.com/read/
23 See http://openjdk.java.net/ for more information about the OpenJDK.
25 Simple Build Instructions:
27 0. Get the necessary system software/packages installed on your system, see
28 http://hg.openjdk.java.net/jdk8/build/raw-file/tip/README-builds.html
30 1. If you don't have a jdk6 installed, download and install a JDK 6 from
31 http://java.sun.com/javase/downloads/index.jsp
32 Set the environment variable ALT_BOOTDIR to the location of JDK 6.
34 2. Check the sanity of doing a build with your current system:
35 make sanity
36 See README-builds.html if you run into problems.
38 3. Do a complete build of the OpenJDK:
39 make all
40 The resulting JDK image should be found in build/*/j2sdk-image
42 where make is GNU make 3.81 or newer, /usr/bin/make on Linux usually
43 is 3.81 or newer.
45 Complete details are available in README-builds.html.
