make - Get dependencies from another Makefile -



make - Get dependencies from another Makefile -

i'm trying utilize multiple makefiles this:

in ~/generator/makefile:

foo.xml: foo-part1.xml foo-part2.xml foo-part3.xml ./generate $^ > $@

and in ~/some/other/dir/makefile:

foo.xml: $(make) -c ~/generator $@ mv ~/generator/$@ $@

the problem is: when go ~/some/other/dir/ , run make foo.xml, there no dependency list foo.xml, , make -c ~/generator foo.xml isn't called if (for instance) ~/generator/foo-part1.xml newer target.

the solution thought of copying dependency list absolute paths ~/some/other/dir/makefile, quite awful:

foo.xml: ~/generator/foo-part1.xml ~/generator/foo-part2.xml ~/generator/foo-part3.xml

then, question is: there way in makefile inquire another makefile dependencies of target? or forwards request foo.xml makefile , collect result? want sec makefile rely on first 1 when comes decide if target should rebuilt, , when comes build it.

i solved having 2 rules in sec makefile:

and in ~/some/other/dir/makefile:

.phony: ~/generator/foo.xml ~/generator/foo.xml: $(make) -c ~/generator $(notdir $@) foo.xml: ~/generator/foo.xml cp $< $@

makefile make
