毕业设计 Makefile 编写

一天下来，Makefile终于完成了，可以实现c文件和头文件不同目录，并将输出文件输出到其他如output目录，将执行文件和makefile文件并列：
源码如下：

# ============================================================

# make clean        :  clean output/                    ======

MAKE_PATH 	:= $(CURDIR)

# ---------------------------------------------------------

SRCS_DIR	=$(wildcard $(SRC_PATH)/*.c) 
SRCS 	= $(notdir  $(SRCS_DIR) )

OBJS 	= $(patsubst %.c,%.o,$(SRCS)) 
OBJS_DIR = $(addprefix $(OUT_PATH)/, $(OBJS))

default: all
.PHONY: mk_output_dir   clean  cleanall
all:clean mk_output_dir  $(OBJS)  $(TARGET) 
# 搜索目录下.c和.o文件
vpath %.c $(SRC_PATH)
vpath %.o $(OUT_PATH)

mk_output_dir:
	@$(MKDIR) $(OUT_PATH)

$(OBJS):%.o:%.c
	@$(CC) $(INC_PATH) $(CFLAGS) $(OUT_PATH)/$@ -c $<

$(TARGET) :$(OBJS_DIR)
	@$(CC) $(INC_PATH) $(LIBS) $(CFLAGS) $@  $^

clean:
	$(RM) $(OUT_PATH) 

cleanall:
	$(RM) $(OUT_PATH) $(MAKE_PATH)/main
