This has been tested against Oracle Enterprise Linux# 5.5. Set variables RPM_DIR_x86_64 and RPM_DIR_i686 respectively to point# to directory containing the RPMs.## By default this Makefile will build crosstools for:# * i686-unknown-linux-gnu# * x86_64-unknown-linux-gnu# The x86_64 version of the compilers will work in multi arch mode and will# be able to compile 32bit binaries with the -m32 flag. This makes the# explicit cross compiler for i686 somewhat redundant and is a known issue.## To build the full set of crosstools, use a command line looking like this:## make tars RPM_DIR_x86_64=/tmp/oel64-x86_64/Packages/ RPM_DIR_i686=/tmp/oel64-i686/Packages/## To create a x86_64 package without the redundant i686 cross compiler, do# like this:## make tars platforms=x86_64-unknown-linux-gnu RPM_DIR_x86_64=/tmp/oel64-x86_64/Packages/ RPM_DIR_i686=/tmp/oel64-i686/Packages/## Main makefile which iterates over all host and target platforms.#os := $(shell uname -o)cpu := x86_64#$(shell uname -p)## This wrapper script can handle exactly these platforms#platforms := $(foreach p,x86_64 i686,$(p)-unknown-linux-gnu)#platforms := $(foreach p,x86_64,$(p)-unknown-linux-gnu)# Figure out what platform this is building on.me := $(cpu)-$(if $(findstring Linux,$(os)),unknown-linux-gnu)$(info Building on platform $(me))all compile : $(platforms)ifeq (,$(SKIP_ME)) $(foreach p,$(filter-out $(me),$(platforms)),$(eval $(p) : $$(me)))endifOUTPUT_ROOT = $(abspath ../../build/devkit)RESULT = $(OUTPUT_ROOT)/resultsubmakevars = HOST=$@ BUILD=$(me) \ RESULT=$(RESULT) PREFIX=$(RESULT)/$@ \ OUTPUT_ROOT=$(OUTPUT_ROOT)$(platforms) : @echo 'Building compilers for $@' @echo 'Targets: $(platforms)' for p in $@ $(filter-out $@,$(platforms)); do \ $(MAKE) -f Tools.gmk all $(submakevars) \ TARGET=$$p || exit 1 ; \ done @echo 'Building ccache program for $@' $(MAKE) -f Tools.gmk ccache $(submakevars) TARGET=$@ @echo 'All done"'$(foreach a,i686 x86_64,$(eval $(a) : $(filter $(a)%,$(platforms))))ia32 : i686today := $(shell date +%Y%m%d)define Mktar $(1)_tar = $$(RESULT)/sdk-$(1)-$$(today).tar.gz $$($(1)_tar) : PLATFORM = $(1) TARFILES += $$($(1)_tar) $$($(1)_tar) : $(1) $$(shell find $$(RESULT)/$(1))endef$(foreach p,$(platforms),$(eval $(call Mktar,$(p))))tars : all $(TARFILES)onlytars : $(TARFILES)%.tar.gz : @echo 'Creating compiler package $@' cd $(RESULT)/$(PLATFORM) && tar -czf $@ * touch $@clean : rm -rf build resultFORCE :.PHONY : $(configs) $(platforms)
