Makefile setup

I'm still working on green-engine and I'm having trouble setting up the Makefiles. I have a main /src directory with a Makefile and a Makedefs (with some global defines, such as CFLAGS and the like). And I also have subfolders each with their own Makefile (I'm required to do this by my professor for the class). However, I cannot seem to get make to correctly handle all the dependencies in this setup.

Here is the Makefile in the /src directory:

Code:

include Makedefs

UTIL = util

ENGINE = engine

MAIN = main

BACKEND = backend

OBJS =  $(BACKEND)/glutApp.o \

              $(MAIN)/main.o \

              $(UTIL)/DrawStuff.o

UT_OBJS = $(UTIL)/utest_Error.o \

      $(ENGINE)/utest_Variable.o \

      $(ENGINE)/utest_VariableTableInstance.o \

      $(MAIN)/testmain.o \

      $(ENGINE)/utest_VariableTableTemplate.o \

      $(ENGINE)/utest_KeyNameTable.o \

      $(ENGINE)/utest_TemplateTable.o \

      $(ENGINE)/utest_InstancePool.o

all : $(OUT)

$(UT_OUT) :

    cd $(BACKEND) ; make $(UT_OUT)

    cd $(ENGINE) ; make $(UT_OUT)

    cd $(MAIN) ; make $(UT_OUT)

    cd $(UTIL) ; make $(UT_OUT)

    $(CC) -o $(UT_OUT) $(LDFLAGS) $(UT_OBJS) $(UT_LIBS)

$(OUT) :

    cd $(BACKEND) ; make $(OUT)

    cd $(ENGINE) ; make $(OUT)

    cd $(MAIN) ; make $(OUT)

    cd $(UTIL) ; make $(OUT)

    $(CC) -o $(OUT) $(LDFLAGS) $(OBJS) $(LIBS)

clean:

    rm -f $(UT_OUT) $(OUT) *.o

    cd $(BACKEND) ; make clean

    cd $(ENGINE) ; make clean

    cd $(MAIN) ; make clean

    cd $(UTIL) ; make clean

cleantemp: 

    rm -f $(UTIL)/*~ $(ENGINE)/*~ $(BACKEND)/*~ *~ $(MAIN)/*~

cleandepend:

    rm -f $(BACKEND)/.depend

    rm -f $(UTIL)/.depend

    rm -f $(MAIN)/.depend

    rm -f $(ENGINE)/.depend

depend: 

    cd $(BACKEND) ; make depend

    cd $(MAIN) ; make depend

    cd $(UTIL) ; make depend

    cd $(ENGINE) ; make depend

Here is the Makedefs file in the /src directory:

Code:

# the default compiler

CC = g++

# CFLAGS for engine and test runner

CFLAGS = -g -Wall -I.. -I/usr/local/include -DUSE_GLUT_HEADERS

# LDFLAGS for both unit test runner and engine

LDFLAGS = -g -L/usr/local/lib -L/usr/lib

# library files for OpenGL

GL_LIBS = -lglut

# Library flags for grun and test runner

LIBS = $(GL_LIBS)

UT_LIBS = -lcppunit -ldl

# the output file names

OUT = grun

UT_OUT = utest

# default rule 

.cpp.o:

    $(CC) -c -o $@ $(CFLAGS) $<

And here is a sample Makefile from one of the subdirectories:

Code:

include ../Makedefs

SRCS = 

OBJS = $(SRCS:.cpp=.o)

UT_SRCS = utest_InstancePool.cpp \

      utest_KeyNameTable.cpp \

      utest_TemplateTable.cpp \

      utest_Variable.cpp \

      utest_VariableTableInstance.cpp \

      utest_VariableTableTemplate.cpp

UT_OBJS = $(UT_SRCS:.cpp=.o)

all : $(OUT) $(UT_OUT)

$(OUT) : $(OBJS) .depend

$(UT_OUT) : $(UT_OBJS) .depend

depend : .depend

.depend : 

    $(CC) -M $(CFLAGS) $(SRCS) $(UT_SRCS) > .depend

clean : 

    rm -f *.o

cleandepend : 

    rm -f .depend

-include .depend

Any idea how to do this the correct way?

WARNING-NO ACTUAL MAKEFILE HELP IN THIS POST.
If you don't really need Makefiles, I'd switch to another make system i.e. rake, scons, CMake, or something else. Alternatively, you could use auto* tools.
Sorry I can't be more help; I dumped Makefiles a long time ago

It's not magic, it's Ruby.

SCons FTW

When I've written Makefiles in the past, I've found this to be incredibly helpful:
