|
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/ |
