duke@2: README:
ohair@276:   This file should be located at the top of the OpenJDK Mercurial root
ohair@276:   repository. This root repository will include a "make" directory,
ohair@276:   and a Makefile for building the entire OpenJDK.
ohair@276:   A full OpenJDK repository set (forest) should also include the following
ohair@276:   6 nested repositories:
ohair@276:     "jdk", "hotspot", "langtools", "corba", "jaxws"  and "jaxp".
ohair@276:   There are also several source downloads for the jax* repositories that
ohair@276:   will be needed.
ohair@276: 
ohair@276:   This one root repository can be obtained with something like:
ohair@276:     hg clone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7
ohair@276:   To make sure you have all the nested repositories, you can run:
ohair@276:     cd openjdk7 && sh ./get_source.sh
ohair@276:   (This is identical to using the Mercurial Forest Extension command 
ohair@276:    'hg fclone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7').
ohair@276:   People unfamiliar with Mercurial should read the first few chapters of
ohair@276:   the Mercurial book: http://hgbook.red-bean.com/read/
duke@2: 
duke@2:   See http://openjdk.java.net/ for more information about the OpenJDK.

duke@2: Simple Build Instructions:
ohair@276:   
ohair@276:   0. Get the necessary system software/packages installed on your system, see
ohair@276:      http://hg.openjdk.java.net/jdk7/build/raw-file/tip/README-builds.html
duke@2: 
ohair@276:   1. If you don't have a jdk6 installed, download and install a JDK 6 from
duke@2:      http://java.sun.com/javase/downloads/index.jsp
ohair@276:      Set the environment variable ALT_BOOTDIR to the location of JDK 6.
duke@2: 
ohair@276:   2. Check the sanity of doing a build with your current system:
ohair@320:        make sanity
duke@2:      See README-builds.html if you run into problems.
duke@2:   
ohair@276:   3. Do a complete build of the OpenJDK:
ohair@320:        make all
duke@2:      The resulting JDK image should be found in build/*/j2sdk-image
duke@2: 
ohair@320: where make is GNU make 3.81 or newer, /usr/bin/make on Linux usually
ohair@320: is 3.81 or newer.
