# This Makefile, together with Tools.gmk, can be used to compile a set of
|
|
|
29 |
# gcc based cross compilation, portable, self contained packages, capable
|
|
18021
|
30 |
# of building OpenJDK.
|
|
20363
|
31 |
#
|
|
|
32 |
# In addition to the makefiles, access to Oracle Linux installation
|
|
|
33 |
# media is required. This has been tested against Oracle Enterprise Linux
|
|
18021
|
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 |
#
|
|
20363
|
46 |
# make tars RPM_DIR_x86_64=/tmp/oel55-x86_64/Server/ RPM_DIR_i686=/tmp/oel55-i686/Server/
|
|
18021
|
47 |
#
|
|
20363
|
48 |
# To create a x86_64 package without the redundant i686 cross compiler, do
|
|
18021
|
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/
