     2   This file should be located at the top of the OpenJDK Mercurial repository

     3   forest. This top or enclosing repository will include a "make" directory,

     4   and a Makefile at the very top of the repository.

     5   It should also include the 6 repositories: "jdk", "hotspot", "langtools",

     6   "corba", "jaxws"  and "jaxp".

    10 Simple Build Instructions:

    11 

    12   1. Download and install a JDK 6 from

    13      http://java.sun.com/javase/downloads/index.jsp

    14      Set the environment variable ALT_BOOTDIR to the location of this JDK 6.

    15 

    16   2. Download and install the Binary Plugs for the most recent JDK7 from

    17      http://download.java.net/openjdk/jdk7/

    18      Set the environment variable ALT_BINARY_PLUGS_PATH to the location of

    19      these binary plugs.

    20      

    21   3. Check the sanity of doing a build with the current machine:

    22        gnumake sanity

    23      See README-builds.html if you run into problems.

    24   

    25   4. Do a complete build of the jdk:

    26        gnumake all

    27      The resulting JDK image should be found in build/*/j2sdk-image

    28 

    29 where gnumake is GNU make 3.78.1 or newer, /usr/bin/make on Linux and

    30 /usr/sfw/bin/gmake or /opt/sfw/bin/gmake on Solaris.
