need help with the Makefile

Hi..

I am working on a project to define the make system. Currently customer has ~50 shell scripts for different deliverables which does copying the files around and then in certain cases modifying them(ah…) and the compiling with the different CFLAGS. Some scripts are platform specific.

I need to convert them to a Make system. I am familiar with the simple makefile structure and I am planning to use gnu-make.

I have basic makefile structure in place. The master makefile will include ‘common.mk’ (which has all the required variables) and ‘rules.mk’ (which has general rules for compile and link).

I have couple of questions as follows:

in common.mk, how do I set variables for different platforms and different OS versions(for the same platform)
is there any way to set target specific variables(CFLAGS/LDFLAGS/INCLUDE) instead of passing them at the command line to $(MAKE). As CFLAGS list is long.

targetx:

CFLAGS += XX

LDFLAGS += XX

$(MAKE) –C xdir $(CFLAGS)

Targety:

CFLAGS += YY

LDFLAGS += YY

$(MAKE) –C ydir $(CFLAGS)

Thanks in advance..
