Hmm, I am just a humble computer science student, but my Makefile for my
last project did what you said you wanted but is much more straight forward.
However, it *will* recompile missing .o files... It is below. It produces
two binaries, most of the modules are the same except for different compile
flags. Each one has a different main module.


# Makefile for least-cost communications anaylzer
# (project for Univ of Del, CIS 220 class)

CC = g++

#CFLAGS is *normal* flags for compiling program
#DFLAGS is compiled into the driver programs

CFLAGS = -O -g
DFLAGS = -DDEBUG -g

# OBJS is normal objects, DOBJS is debugging objects for driver program

OBJS = symtable.o main.o fileio.o table.o util.o
DOBJS = dsymtable.o dmain.o fileio.o dtable.o dutil.o

all: prog2 dprog2

prog2: $(OBJS)
	$(CC) $(CFLAGS) $(OBJS) -o prog2

dprog2:	$(DOBJS)
	$(CC) $(DFLAGS) $(DOBJS) -o dprog2

symtable.o: symtable.cc symtable.h general.h
	$(CC) $(CFLAGS) -c symtable.cc

table.o: table.cc table.h general.h
	$(CC) $(CFLAGS) -c table.cc

main.o: main.cc general.h symtable.h table.h util.h
	$(CC) $(CFLAGS) -c main.cc

dsymtable.o: symtable.cc symtable.h general.h
	$(CC) $(DFLAGS) -c symtable.cc -o dsymtable.o

dtable.o: table.cc table.h general.h
	$(CC) $(DFLAGS) -c table.cc -o dtable.o

dmain.o: driver.cc driver.h general.h
	$(CC) $(DFLAGS) -c driver.cc -o dmain.o

fileio.o: fileio.cc fileio.h general.h
	$(CC) $(CFLAGS) -c fileio.cc

util.o: util.cc util.h general.h fileio.h
	$(CC) $(CFLAGS) -c util.cc

dutil.o: util.cc util.h general.h fileio.h
	$(CC) $(DFLAGS) -c util.cc -o dutil.o

clean:
	rm -rf $(DOBJS) $(OBJS) prog2 dprog2 *~ core

strip:
	strip prog2 dprog2
	chmod 711 prog2 dprog2 .
	rm -rf $(OBJS) *~ core
