I like make, it allow to automate complex tasks with not much code, and it make handling dependencies very easy.
For a simple test based on few packages I wrote this define:
define configure-rule
$(1)_install = $(DESTDIR)/$(1)-install-my-stamp
$(1)_builddir = $$($(1)_dir)/build
$(DESTDIR)/$(1)-install-my-stamp: $$($(1)_deps)
ifneq ($$($(1)_pre_config),)
$$($(1)_pre_config)
endif
mkdir -p $$($(1)_builddir)
cd $$($(1)_builddir) && \
$$($(1)_env) ../configure --cache-file=$(SRCDIR)/$(1)-config.cache \
$$($(1)_configure)
$(NICE) make -C $$($(1)_builddir) $$($(1)_make_target) $(PARALLEL)
ifneq ($$($(1)_post_make),)
$$($(1)_post_make)
endif
touch $$@
.PHONY: build-$(1) clean-$(1)
build-$(1): $$($(1)_install)
clean-$(1):
-rm -fr $$($(1)_builddir) $$($(1)_install) $(SRCDIR)/$(1)-config.cache
endef
Then use few variables for each packet:
mpc_dir = src/mpc-0.8.1
mpc_env = CONFIG_SITE=$(SRCDIR)/config.site
mpc_configure = --prefix=$(DESTDIR) \
--disable-shared --enable-static \
--with-gmp=$(DESTDIR) --with-mpfr=$(DESTDIR)
mpc_deps = $(untar_dep) $(gmp_install) $(mpfr_install)
mpc_make_target = install
$(eval $(call configure-rule,mpc))
The complete Makefile.gz, it build gcc-4.7.2 but has been used for test purpose only, don’t use it as reference for building gcc.
