Simple Build Instructions:

  1. Download and install a JDK 6 from
     Set the environment variable ALT_BOOTDIR to the location of this JDK 6.

  2. Either download and install the latest JDK7 from, 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.
  3. Check the sanity of doing a build with the current machine:
       cd make && gnumake sanity
     See README-builds.html if you run into problems.
  4. Do a partial build of the jdk:
       cd make && gnumake all
  5. Construct the images:
       cd make && gnumake images
     The resulting JDK image should be found in build/*/j2sdk-image
