28# This Makefile, together with Tools.gmk, can be used to compile a set of
29# gcc based cross compilation, portable, self contained packages, capable
30# of building OpenJDK.
31#
32# In addition to the makefiles, access to Oracle Linux installation
33# media is required. This has been tested against Oracle Enterprise Linux
34# 5.5. Set variables RPM_DIR_x86_64 and RPM_DIR_i686 respectively to point
35# to directory containing the RPMs.
36#
37# By default this Makefile will build crosstools for:
38# * i686-unknown-linux-gnu
39# * x86_64-unknown-linux-gnu
40# The x86_64 version of the compilers will work in multi arch mode and will
41# be able to compile 32bit binaries with the -m32 flag. This makes the
42# explicit cross compiler for i686 somewhat redundant and is a known issue.
43#
44# To build the full set of crosstools, use a command line looking like this:
45#
46# make tars RPM_DIR_x86_64=/tmp/oel64-x86_64/Packages/ RPM_DIR_i686=/tmp/oel64-i686/Packages/
47#
48# To create a x86_64 package without the redundant i686 cross compiler, do
49# like this:
50#
51# make tars platforms=x86_64-unknown-linux-gnu RPM_DIR_x86_64=/tmp/oel64-x86_64/Packages/ RPM_DIR_i686=/tmp/oel64-i686/Packages/
