Hey folks,

Sorry to get in on the ground floor with such a dumb question, but...

I am running into a brick wall with this make program. I am (trying)
to use the mak373b distribution to compile my programs, which use the
Allegro library. From the command line, they compile just fine. It's
only under make that I have the problem. What happens is that it
apparently fails to link in the allegro headers. Here is the makefile:

SHELL = /bin/sh

FLAGS = ../lib/liballeg.a -liostream

vpath %*.h ../include

dots : colors.cpp
	gcc $(FLAGS) colors.cpp

I have tried a great many changes on this already. The SHELL, FLAGS
and vpath statements are late additions, the flags statement was
changed to reflect the absolute path of liballeg.a (from using the
switch -lalleg), and various permutations of:

dots.exe : colors.o
	(blah)

colors.o : colors.cpp
	(blah)

Yes, there is only one file. Anyway, the make program runs up to the
ld stage, then spews out about 100 references to undefined functions,
all of which come from the allegro library.

Points of note:  allegro.h is currently contained in ../allegro,
.../include, and the current directory. The allegro directory is even
in the Dos search path. Running a P75, 16 megs, with win95 in dos box.

Hmm, that's all I can think of... Any advice out there?
