##########################################################################################
#
# This Makefile, together with Tools.gmk, can be used to compile a set of
# gcc based cross compilation, portable, self contained packages, capable
# of building OpenJDK.
#
# In addition to the makefiles, access to Oracle Linux installation
# media is required. This has been tested against Oracle Enterprise Linux
# 5.5. Set variables RPM_DIR_x86_64 and RPM_DIR_i686 respectively to point
# to directory containing the RPMs.
#
# By default this Makefile will build crosstools for:
# * i686-unknown-linux-gnu
# * x86_64-unknown-linux-gnu
# The x86_64 version of the compilers will work in multi arch mode and will
# be able to compile 32bit binaries with the -m32 flag. This makes the
# explicit cross compiler for i686 somewhat redundant and is a known issue.
#
# To build the full set of crosstools, use a command line looking like this:
#
# make tars RPM_DIR_x86_64=/tmp/oel64-x86_64/Packages/ RPM_DIR_i686=/tmp/oel64-i686/Packages/
#
# To create a x86_64 package without the redundant i686 cross compiler, do
# like this:
#
# make tars platforms=x86_64-unknown-linux-gnu RPM_DIR_x86_64=/tmp/oel64-x86_64/Packages/ RPM_DIR_i686=/tmp/oel64-i686/Packages/

#
# Main makefile which iterates over all host and target platforms.
#

os := $(shell uname -o)
cpu := x86_64
#$(shell uname -p)

#
# This wrapper script can handle exactly these platforms
#
platforms := $(foreach p,x86_64 i686,$(p)-unknown-linux-gnu)
#platforms := $(foreach p,x86_64,$(p)-unknown-linux-gnu)

# Figure out what platform this is building on.
me := $(cpu)-$(if $(findstring Linux,$(os)),unknown-linux-gnu)
