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/oel55-x86_64/Server/ RPM_DIR_i686=/tmp/oel55-i686/Server/
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/oel55-x86_64/Server/ RPM_DIR_i686=/tmp/oel55-i686/Server/
