  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/
