# 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.
#
# The Solaris Studio installation must contain at least these packages:
# developer/solarisstudio-124/backend               12.4-1.0.6.0               i--
# developer/solarisstudio-124/c++                   12.4-1.0.10.0              i--
# developer/solarisstudio-124/cc                    12.4-1.0.4.0               i--
# developer/solarisstudio-124/library/c++-libs      12.4-1.0.10.0              i--
# developer/solarisstudio-124/library/math-libs     12.4-1.0.0.1               i--
# developer/solarisstudio-124/library/studio-gccrt  12.4-1.0.0.1               i--
# developer/solarisstudio-124/studio-common         12.4-1.0.0.1               i--
# developer/solarisstudio-124/studio-ja             12.4-1.0.0.1               i--
# developer/solarisstudio-124/studio-legal          12.4-1.0.0.1               i--
# developer/solarisstudio-124/studio-zhCN           12.4-1.0.0.1               i--
# In particular backend 12.4-1.0.6.0 contains a critical patch for the sparc
