7003845: README-builds document proper location of forest extension, provide alternatives
Reviewed-by: robilad

duke@2 1 README:
ohair@276 2 This file should be located at the top of the OpenJDK Mercurial root
ohair@276 3 repository. This root repository will include a "make" directory,
ohair@276 4 and a Makefile for building the entire OpenJDK.
ohair@276 5 A full OpenJDK repository set (forest) should also include the following
ohair@276 6 6 nested repositories:
ohair@276 7 "jdk", "hotspot", "langtools", "corba", "jaxws" and "jaxp".
ohair@276 8 There are also several source downloads for the jax* repositories that
ohair@276 9 will be needed.
ohair@276 10
ohair@276 11 This one root repository can be obtained with something like:
ohair@276 12 hg clone openjdk7
ohair@276 13 To make sure you have all the nested repositories, you can run:
ohair@276 14 cd openjdk7 && sh ./
ohair@276 15 (This is identical to using the Mercurial Forest Extension command
ohair@276 16 'hg fclone openjdk7').
ohair@276 17 People unfamiliar with Mercurial should read the first few chapters of
ohair@276 18 the Mercurial book:

duke@2 20 See for more information about the OpenJDK.
duke@2 21
duke@2 22 Simple Build Instructions:
ohair@276 23
ohair@276 24 0. Get the necessary system software/packages installed on your system, see
ohair@276 25
duke@2 26
ohair@276 27 1. If you don't have a jdk6 installed, download and install a JDK 6 from
duke@2 28
ohair@276 29 Set the environment variable ALT_BOOTDIR to the location of JDK 6.
duke@2 30
ohair@276 31 2. Check the sanity of doing a build with your current system:
duke@2 32 gnumake sanity
duke@2 33 See README-builds.html if you run into problems.
duke@2 34
ohair@276 35 3. Do a complete build of the OpenJDK:
duke@2 36 gnumake all
duke@2 37 The resulting JDK image should be found in build/*/j2sdk-image
duke@2 38
ohair@262 39 where gnumake is GNU make 3.81 or newer, /usr/bin/make on Linux and
duke@2 40 /usr/sfw/bin/gmake or /opt/sfw/bin/gmake on Solaris.
