Hello all,

I'm trying to clean up the source tree for some software I'm writing.
The program itself is relatively simple, but is very fragmented; i.e. it
has a lot of source files. I'd like to write one top-level Makefile that
is able to find all of my source files, build the object files, and put
them into a separate directory. I'm thinking this can't be that
difficult, but I haven't figured it out yet.

I'm trying to use $(addprefix) build lists of source files and object
files containing the relative paths for each. The problem is that
$(addprefix) never seems to be evaluated. When I run 'make -p',
$OBJECT_LIST looks exactly like in does in my Makefile, which is listed
below. Fixes or pointers to a somewhat simple example greatly
appreciated...

Thanks,
-Andrew

#### Begin Makefile ####

## compiler settings
CC = gcc
OPTIONS = -Wall -g

## directory layout
BASEDIR = ../alice
SOURCEDIR = $(BASEDIR)/sources
OBJECTDIR = $(BASEDIR)/objects
DOCSDIR = $(BASEDIR)/documentation

## sources
SOURCES = main.c help.c status.c buffer.c device.c error.c insane.c

## objects
OBJECTS = main.o help.o status.o buffer.o device.o error.o insane.o

## lists containing paths
SOURCES_LIST = $(addprefix, $(SOURCEDIR), $(SOURCE))
OBJECTS_LIST = $(addprefix, $(OBJECTDIR), $(OBJECTS))

## targets
alice: $(OBJECT_LIST)
        $(CC) $(OPTIONS) -o $@ $(OBJECT_LIST)

$(OBJECTS_LIST): alice.h
        $(CC) $(OPTIONS) -c $(SOURCES_LIST)

clean:
        rm -f $(OBJECTS_LIST) *.core alice;

#### End Makefile ####
