ihse@839: # This Makefile, together with Tools.gmk, can be used to compile a set of
ihse@839: # gcc based cross compilation, portable, self contained packages, capable
erikj@740: # of building OpenJDK.
ihse@839: #
ihse@839: # In addition to the makefiles, access to Oracle Linux installation
ihse@839: # media is required. This has been tested against Oracle Enterprise Linux
erikj@740: # 5.5. Set variables RPM_DIR_x86_64 and RPM_DIR_i686 respectively to point
erikj@740: # to directory containing the RPMs.
erikj@740: #
erikj@740: # By default this Makefile will build crosstools for:
erikj@740: # * i686-unknown-linux-gnu
erikj@740: # * x86_64-unknown-linux-gnu
erikj@740: # The x86_64 version of the compilers will work in multi arch mode and will
erikj@740: # be able to compile 32bit binaries with the -m32 flag. This makes the
erikj@740: # explicit cross compiler for i686 somewhat redundant and is a known issue.
erikj@740: #
erikj@740: # To build the full set of crosstools, use a command line looking like this:
erikj@740: #
ihse@839: # make tars RPM_DIR_x86_64=/tmp/oel55-x86_64/Server/ RPM_DIR_i686=/tmp/oel55-i686/Server/
erikj@740: #
ihse@839: # To create a x86_64 package without the redundant i686 cross compiler, do
erikj@740: # like this:
erikj@740: #
erikj@740: # make tars platforms=x86_64-unknown-linux-gnu RPM_DIR_x86_64=/tmp/oel55-x86_64/Server/ RPM_DIR_i686=/tmp/oel55-i686/Server/
