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：

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

# Makefile for project (by chen long 2019.03.29)        ======

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

# make 					:	make clean && make all      ======

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

TARGET 	:= app

MKDIR 	:= mkdir -p

RM       	:= rm -rf

CC			:= gcc #arm-linux-gcc

# LIBS 	:= -lpthread

CFLAGS	:= -o

MAKE_PATH 	:= $(CURDIR)

INC_PATH 		:= -I$(MAKE_PATH)/include

SRC_PATH 		:= $(MAKE_PATH)/src

OUT_PATH 		:= $(MAKE_PATH)/output

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

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

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
