README:

   This file should be located at the top of the jdk Mercurial repository.

   See http://openjdk.java.net/ for more information about the OpenJDK.

 Simple Build Instructions:

   1. Download and install a JDK 6 from

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

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

   2. Download and install the JIBX libraries, version 1.1.5 from

      http://sourceforge.net/project/showfiles.php?group_id=69358&package_id=68290

      You'll need the following four JAR files:

          bcel.jar

          jibx-bind.jar

          jibx-run.jar

          xpp3.jar

      Set the environment variable ALT_JIBX_LIBS_PATH to the location of

      these JAR files.

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

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

      Set the environment variable ALT_BINARY_PLUGS_PATH to the location of

      these binary plugs.

   4. Either download and install the latest JDK7 from

      http://download.java.net/openjdk/jdk7/, or build your own complete

      OpenJDK7 by using the top level Makefile in the OpenJDK Mercurial forest.

      Set the environment variable ALT_JDK_IMPORT_PATH to the location of

      this latest JDK7 or OpenJDK7 build.

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

        cd make && gnumake sanity

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

   6. Do a partial build of the jdk:

        cd make && gnumake all

   7. Construct the images:

        cd make && gnumake images

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