# Stephen Bannasch, 2009 11 29, tested on Mac OS X 10.5.8
#
# This script assumes:
#   Apple's Mac OX X developer tools are installed
#   hg (mercurial) is installed
#   The forest extension to hg is installed
#   SoyLatte 32-bit Java 1.6 is located here: 
#     /usr/local/soylatte16-i386-1.0.3
#   ALT_JIBX_LIBS_PATH points to JIBX v1.1.5

#
# Prerequisites:
#   SoyLatte 32-bit Java 1.6
#
#    Download v1.0.3 of Landon Fuller's SoyLatte Java 1.6 32 bit release
#    and install or link it to  /usr/local/soylatte16-i386-1.0.3 and test it:
#
#      $ /usr/local/soylatte16-i386-1.0.3/bin/java -version
#      java version "1.6.0_03-p3"
#      Java(TM) SE Runtime Environment (build 1.6.0_03-p3-landonf_19_aug_2008_14_55-b00)
#      Java HotSpot(TM) Server VM (build 1.6.0_03-p3-landonf_19_aug_2008_14_55-b00, mixed mode)
#
#   JiBX v1.1.5 (Binding XML to Java libraries)
#
#     Download and install v1.1.5 of JIBX from sourceforge
#     http://sourceforge.net/projects/jibx/files/
#     update the ALT_JIBX_LIBS_PATH variable in this script.
#
# Basic setup after installing prerequisites:
#   hg fclone http://hg.openjdk.java.net/bsd-port/bsd-port bsd
#   cd bsd
#
# Create the ALT_COMPILER_PATH directoru and compiler links:
#   In the sources/ dir create the ALT_COMPILER_PATH dir and 
#   the following symbolic links to the gcc 4.0 compilers:
#
#      cd sources
#      mkdir ALT_COMPILER_PATH
#      cd ALT_COMPILER_PATH
#      ln -s /usr/bin .SOURCE
#      ln -s .SOURCE/g++-4.0 g++
#      ln -s .SOURCE/gcc-4.0 gcc
#
# Building:
#   cd bsd
#   source update.sh
#
# After building see if the new build can report it's version number:
#    $ ./build/bsd-amd64/j2sdk-image/bin/java -version
#    openjdk version "1.7.0-internal"
#    OpenJDK Runtime Environment (build 1.7.0-internal-stephen_2010_10_08_15_33-b00)
#    OpenJDK 64-Bit Server VM (build 19.0-b05, mixed mode)
