Thread: Make file trouble

Hi

I'm trying to figure out how to make the makefile for the following.
I have bookie.c and client.c which should be compiled into separated executables.
I also have one helper.h and helper.c that are needed in both booie.c and client.c

How should I go about for the makefile?
Is it possible to compile the whole thing in just one make file?
How do put the linkage of the header in the makefile?

So far my makefile is:

Code:

FLAGS  = -Wall -g -std=c99
CC     = gcc
PROG   = Client
OBJS   = semlib.o helper.o client.o

all:	${PROG}

clean:
	rm ${OBJS} ${PROG} *~
  
${PROG}:	${OBJS}
	${CC} ${FLAGS} ${OBJS} -o $@

.c.o:
	${CC} ${FLAGS} $< -c

##########################

semlib.o: semlib.c

helper.o: helper.c

client.o: client.c

A very simple example for you:

Code:

PREFIX = $(PWD)/..
BUILD_DIR = $(PWD)
FIXDATE = $(BUILD_DIR)/fixbuild
MDEPS = $(BUILD_DIR)/mkdep
DEPSFILE = $(BUILD_DIR)/.Makefile.deps
CPP  = $(CROSS)g++
CC   = $(CROSS)gcc
STRIP = $(CROSS)strip
RES  =
OBJ  = kybd.o lib.o hp8450.o hp8450ctrl.o $(RES)
LIBS +=
INCS =
BIN  = hp8450
CFLAGS = $(DEFS) $(INCS) -Wall -O2 $(EXTRADEFS)
RM = rm -f

.PHONY: all all-before all-after clean

all: fixdate mkdeps all-before $(IOCONVERTBIN) $(TESTDISPBIN) $(BIN) all-after

fixdate:
        @ ${FIXDATE} $(BUILD_DIR)

${DEPSFILE}:
mkdeps:
        @ ${MDEPS} ${DEPSFILE}

clean:
        @ ${RM} $(IOCONVERTOBJ) $(OBJ) $(BIN) build.h

$(BIN): $(OBJ)
        @echo Linking $(BIN)...
        @$(CC) $(OBJ) $(CFLAGS)  -o $(BIN) $(LIBS)
ifndef NOSTRIP
                @ echo Stripping $(BIN)
                @$(STRIP) $(BIN)
endif
        @ echo Build Complete

include ${DEPSFILE}

If you want to see the scripts that are used in this one, just let me know and I'll PM them to you.

(Obviously, you still need the bits that tell make how to make the client and bookie executables).

One problem with this is that if you add any header files to the program, you will have to add that header in the Makefile. If you generate all of the dependencies on-the-fly, you don't have to worry about that portion.
