Sorry, but this description is not sufficient for us to determine your
problem.  Please write a complete, but simple, makefile that
demonstrates your problem and show how you invoked it and what the
result was, and why that was wrong.  Just saying it's not right doesn't
mean anything to us.

See http://www.catb.org/~esr/faqs/smart-questions.html.


The information you provide above is not complete: you say you call this
in your makefile:

  $(eval $(call FOOFN,foo))

then you say that FOOFN does this:

  $(eval $(call SET,CFLAGS))

where SET is this:

  define SET
  $$(NAME)_$(1) := $$$$($(1))
  endef

There has to be more than this, because here $(NAME) has no value.  I
can only assume from your description that you intend $(NAME) to have
the value "foo" (the argument you use when you call FOOFN), but that
transition is not shown here, and is certainly critical to the behavior.
