################################################################################

|
#
|
|
# This Makefile, together with Tools.gmk, can be used to compile a set of
|
|
# gcc based cross compilation, portable, self contained packages, capable
|
|
# of building OpenJDK.
|
|
#
|
|
# By default this Makefile will build a native toolchain for the current
|
|
# platform if called with something like this:
|
|
#
|
|
# make tars BASE_OS=OL
|
|
#
|
|
# To build the full set of crosstools for additional platforms, use a command
|
|
# line looking like this:
|
|
#
|
|
# make TARGETS="aarch64-linux-gnu" BASE_OS=Fedora
|
|
# or
|
|
# make TARGETS="arm-linux-gnueabihf ppc64-linux-gnu" BASE_OS=Fedora BASE_OS_VERSION=17
|
|
#
|
|
# to build several devkits for a specific OS version at once.
|
|
# You can find the final results under ../../build/devkit/result/<host>-to-<target>
|
|
#
|
|
# You may want the native toolchain to be used when compiling the cross
|
|
# compilation toolchains. To achieve this, first build the native toolchain,
|
|
# then add the bin directory from this build to the path when invoking this
|
|
# makefile again for cross compilation. Ex:
|
|
#
|
|
# PATH=$PWD/../../build/devkit/result/x86_64-linux-gnu-to-x86_64-linux-gnu/bin:$PATH \
|
|
# make TARGETS="arm-linux-gnueabihf,ppc64-linux-gnu" BASE_OS=Fedora
|
|
#
|
|
# This is the makefile which iterates over all host and target platforms.
