This will allow people to continue to +# build individual directories while some of the targets may not be normally +# defined in that make file. +# +# Non-recursive targets are attached to existing make targets. The +# NONRECURSIVE_TARGETS variable lists the make targets that modified. For +# each target in this list, the NONRECURSIVE_TARGET_<target> variable will +# contain a list of partial variable names. We will then look in variables +# named NONRECURSIVE_TARGETS_<target>_<fragment>_* for information describing +# how to evaluate non-recursive make targets. +# +# Targets are defined by the following variables: +# +# FILE - The make file to evaluate. This is equivalent to +# |make -f <FILE>| +# DIRECTORY - The directory whose Makefile to evaluate. This is +# equivalent to |make -C <DIRECTORY>|. +# TARGETS - Targets to evaluate in that make file. +# +# Only 1 of FILE or DIRECTORY may be defined. +# +# For example: +# +# NONRECURSIVE_TARGETS = export libs +# NONRECURSIVE_TARGETS_export = headers +# NONRECURSIVE_TARGETS_export_headers_FILE = /path/to/exports.mk +# NONRECURSIVE_TARGETS_export_headers_TARGETS = $(DIST)/include/foo.h $(DIST)/include/bar.h +# NONRECURSIVE_TARGETS_libs = cppsrcs +# NONRECURSIVE_TARGETS_libs_cppsrcs_DIRECTORY = $(DEPTH)/foo +# NONRECURSIVE_TARGETS_libs_cppsrcs_TARGETS = /path/to/foo.o /path/to/bar.o +# +# Will get turned into the following: +# +# exports:: +# $(MAKE) -C $(DEPTH) -f /path/to/exports.mk $(DIST)/include/foo.h $(DIST)/include/bar.h +# +# libs:: +# $(MAKE) -C $(DEPTH)/foo /path/to/foo.o /path/to/bar.o + +ifndef INCLUDED_NONRECURSIVE_MK + +define define_nonrecursive_target +$(1):: + $$(MAKE) -C $(or $(4),$$(DEPTH)) $(addprefix -f ,$(3)) $(2) +endef + +$(foreach target,$(NONRECURSIVE_TARGETS), \ + $(foreach entry,$(NONRECURSIVE_TARGETS_$(target)), \ + $(eval $(call define_nonrecursive_target, \ + $(target), \ + $(NONRECURSIVE_TARGETS_$(target)_$(entry)_TARGETS), \ + $(NONRECURSIVE_TARGETS_$(target)_$(entry)_FILE), \ + $(NONRECURSIVE_TARGETS_$(target)_$(entry)_DIRECTORY), \ + )) \ + ) \ +) + +INCLUDED_NONRECURSIVE_MK := 1 +endif + |
