我的项目文件层次是:项目名称/include、output、src
src/admin、stu、tch、common
最外层的Makefile:
DEBUG = y
MYDEBUG = DEBUG
ifeq ($(DEBUG),y)
DEBFLAGS = -O -g -D$(MYDEBUG)
else
DEBFLAGS =
endif
PRJ_HOME := $(shell pwd)
SOURCES := $(wildcard *.c)
OBJECTS := ${SOURCES:%.c=%.o}
INCPATH := -I$(PRJ_HOME)/include -I./
export CFLAGS += $(INCPATH) $(DEBFLAGS)
export CC = gcc
export OUTPUTDIR = $(PRJ_HOME)/output
PROGRAM = system_stu
VPATH = ${OUTPUTDIR}
.PHONY : all
all : ${PROGRAM}
${PROGRAM} : ${OBJECTS} oadmin ocommon ostu otch
$(CC) -o $@ ${OUTPUTDIR}/*.o $(CFLAGS)
%.o:%.c
$(CC) -o ${OUTPUTDIR}/$@ -c $< $(CFLAGS)
oadmin :
@$(MAKE) -C src/admin/
ocommon :
@$(MAKE) -C src/common/
ostu :
@$(MAKE) -C src/stu/
otch :
@$(MAKE) -C src/tch/
.PHONY : clean
clean :
$(RM) ${OUTPUTDIR}/*.o *.o ${PROGRAM}
子目录的Makefile:
SOURCES := $(wildcard *.c)
OBJECTS := ${SOURCES:%.c=%.o}
VPATH = $(OUTPUTDIR)
all : ${OBJECTS}
%.o:%.c
$(CC) -o ${OUTPUTDIR}/$@ -c $< $(CFLAGS)
clean :
