Re: make-system for frameworks

[Nicola Pero]

Sorry for not answering sooner - the current setup is quite correct in
that it allows different tools to share the same object files.

For example, you might have tool1 and tool2, both contining
common.m.  common.m is compiled once into common.o, and is linked into
both tools.  It's sort of a basic static library.

It's quite useful at times.

If you need to have separate object files, my suggestion is that you
override the GNUSTEP_OBJ_DIR definition setup by the gnustep-make system
in your own GNUmakefile.

After including common.make, but before including the caompilation
rules,override GNUSTEP_BOJ_DIR :

ifeq ($(GNUSTEP_INSTANCE),AAA)
 GNUSTEP_OBJ_DIR := $(GNUSTEP_OBJ_DIR)/AAA
else 
ifeq $($(GNUSTEP_INSTANCE),BBB)
  GNUSTEP_OBJ_DIR := $(GNUSTEP_OBJ_DIR)/BBB
endif
endif
