Usage instructions
------------------

You should define at least the following variables in a distro include file or local.conf

PREFERRED_PROVIDER_virtual/java-initial-native = "cacao-initial-native"

PREFERRED_PROVIDER_virtual/java-native = "jamvm-native"
PREFERRED_PROVIDER_virtual/javac-native = "ecj-bootstrap-native"

#For openjdk6:
#PREFERRED_VERSION_openjdk-6-jre = "6b24-1.11.9"
#or
#PREFERRED_VERSION_openjdk-6-jre = "6b27-1.12.8"
#or
PREFERRED_VERSION_openjdk-6-jre = "6b32-1.13.4"
PREFERRED_VERSION_icedtea6-native = "1.8.11"

#For openjdk7:
PREFERRED_VERSION_openjdk-7-jre = "75b13-2.5.4"
PREFERRED_VERSION_icedtea7-native = "2.1.3"

#Sometimes the following is needed:
PREFERRED_PROVIDER_openjdk-6-jre = "openjdk-6-jre"
PREFERRED_PROVIDER_openjdk-7-jre = "openjdk-7-jre"

For conf/bblayers.conf you have to add

BBLAYERS ?= " \
   ...
  path_to_source/meta-openembedded/meta-oe \
  path_to_source/sources/meta-java \
  "

Please note that libstdc++ static is needed on your host to compile icedtea6/7-native
(install libstdc++-static on a Fedora).

For debian-based distributions you need the libstdc++6-$compilerversion-dev package.
