I want to add something to the make command, not edit Makefiles. I could add something to bsd.autotools.mk or some similar Makefile include. but really I want to do it on a case by case basis. there is an averall Makefile (using gmake) that effectively does: cd /usr/ports/$(PORT_DIR); $(BMAKE) $(ARGS) install clean (except it does a lot of them) I want to know what to add to $(ARGS) to make it use the correct include files. my current "work-around" is to do: mv /usr/include /usr/include.hold; ln -s $(STAGING_DIR)/usr/include /usr/include cd /usr/ports/$(PORT_DIR); $(BMAKE) $(ARGS) install clean rm /usr/include; mv /usr/include.hold /usr/include this is *NOT* a clean solution :-) > >
