# This script creates a devkit for building OpenJDK on Solaris by copying
# part of a Solaris Studio installation and cretaing a sysroot by installing
# a limited set of system packages. It is assumed that a suitable pkg
# publisher is configured for the system where the script is executed.
#
# Note that you will need to be able to sudo to root to run the pkg install
# part of this script. It should not affect the running system, but only
# install in a separate temporary image.
#
# The Solaris Studio installation must contain at least these packages:
# developer/developerstudio-126/backend               12.6-1.0.0.0               i--
