6563752: Build and test JDK7 with Sun Studio 12 Express compilers (prep makefiles) Summary: Allows for building with SS12, no longer requires SS11, warns if not SS11 for now. Once SS12 is validated and performance measurements look ok, SS12 will be the validated compiler. Reviewed-by: sspitsyn, ikrylov

README:
  This file should be located at the top of the OpenJDK Mercurial repository
  forest. This top or enclosing repository will include a "make" directory,
  and a Makefile at the very top of the repository.
  It should also include the 6 repositories: "jdk", "hotspot", "langtools",
  "corba", "jaxws"  and "jaxp".

  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 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.
     
  3. Check the sanity of doing a build with the current machine:
       gnumake sanity
     See README-builds.html if you run into problems.
  
  4. Do a complete build of the jdk:
       gnumake all
     The resulting JDK image should be found in build/*/j2sdk-image

where gnumake is GNU make 3.78.1 or newer, /usr/bin/make on Linux and
/usr/sfw/bin/gmake or /opt/sfw/bin/gmake on Solaris.
