You add the make file in the next level in the make file of the first level as one of the commands to execut in the lower level. I have a 3 level tree in my current make file system and in the first level it looks something like this : all: $(BINDIR)$(SERVER) cd scripts;make "MAKEFILE=${MAKEFILE}" cd utilities;make cd key;make cd compiler;make "MAKEFILE=${MAKEFILE}" cd language;make "MAKEFILE=${MAKEFILE}" cd mplex;make "MAKEFILE=${MAKEFILE}" cd Utility;make "MAKEFILE=${MAKEFILE}" d From: programmingblind-bounce@xxxxxxxxxxxxx [mailto:programmingblind-bounce@xxxxxxxxxxxxx] On Behalf Of Tyler Littlefield Sent: Friday, December 26, 2008 2:26 PM To: programmingblind@xxxxxxxxxxxxx Subject: makefile question Hello list, I've got a quick question. I've got a set of programs, each in their own separate folder with makefiles to match. This works, but when I want to build the whole package I have to go from directory to directory. Is there a way perhaps, to make a makefile compile with other makefiles under separate directories? I'd just like one main makefile that will run the makefiles in sub directories, and pass in the argument. So, if I'm at the root of the directory and I want to clean the package, make clean would go to directories a,b,c,d,e and run make clean, etc. TIA,
