I hadn't thought of using macros to generate macros. It's a good idea.
I think it's easier and cleaner to use conditionals:
OS = linux
ifeq ($(OS),linux)
OBJSUFFIX = .o
else ifeq ($(OS),win32)
OBJSUFFIX = .obj
endif
... file$(OBJSUFFIX) ...
Yah, yet it turns out it's easier and cleaner the other way around when
you generate entries with define and eval:
################################################################################
define GENERATE
# $1 is OS, $2 is the build
...
endef
$(eval $(foreach B,debug release, $(foreach S,posix win32, $(call
GENERATE,$S,$B))))
This way in one shot you generate debug and release versions for win32
and posix. (Note that I compile for win32 on linux thwough wine).
