Hello all,
I've fixed my Makefile. Here's a working version, in case it will be of
help to someone else. Oh, by-the-way, this is for GNU make, not BSD
make.
-Andrew
#### Begin Makefile ####
## Makefile for GNU make
## compiler settings
CC = gcc
CFLAGS = -Wall -g
## directory layout
BASEDIR = ../alice
SRCDIR = $(BASEDIR)/sources/
OBJDIR = $(BASEDIR)/objects/
DOCDIR = $(BASEDIR)/documentation
## sources
SRC = main.c help.c status.c buffer.c device.c error.c insane.c
## objects
OBJ = main.o help.o status.o buffer.o device.o error.o insane.o
## list of objects containing relative path for each
OBJLIST = $(addprefix $(OBJDIR), $(OBJ))
## pathes for make to search
VPATH = $(SRCDIR) $(OBJDIR)
alice: $(OBJ)
$(CC) $(CFLAGS) -o $@ $(OBJLIST)
%.o: %.c alice.h
$(CC) $(CFLAGS) -c $< -o $(OBJDIR)$@
clean:
rm $(OBJLIST) *.core
distclean: clean
rm -r *~
#### End Makefile ####
