[aclug-L] Re: master makefile

[Tom Hull <thull@xxxxxxxxxxx>]

The way I do it (in ftwalk) is:

SUBDIRS = tools src test

all :
        for D in $(SUBDIRS); do \
          (cd $$D && $(MAKE) $@); \
        done

fthelp :
        cd src/fthelp && $(MAKE) $(MAKEFLAGS)

ftwalk :
        cd src/ftwalk && $(MAKE) $(MAKEFLAGS)

test :
        cd test && $(MAKE) $(MAKEFLAGS)

I'm not totally happy with this, but at least it's a start,
and it's pretty straightforward. A lot of make tricks strike
me as too much magic.

I use autoconf, and let configure process my Makefile.in into
Makefile. I also separate out an include file for all of the
makefiles to do common definitions.

I think that automake has built-in support for recursive makefiles.
It's probably better than you can (easily) do by hand, but I find
that the makefiles are unreadable, and automake enforces a lot of
prickly GNU-style requirements that may be good ideas but can also
be an annoyance, especially for your own stuff.
