Makefile模板（C++）

Makefile的C++的一个模板，可用于根据不同源文件，生成多个可执行文件 。

CC = g++

DIR_INC = ./include
DIR_SRC = ./src
DIR_OBJ = ./obj
DIR_BIN = ./bin

# SRC = $(wildcard ${DIR_SRC}/*.cpp )
SRC_Server = $(wildcard ${DIR_SRC}/server.cpp ${DIR_SRC}/test1.cpp)
SRC_Client = $(wildcard ${DIR_SRC}/client.cpp  ${DIR_SRC}/test1.cpp)

OBJ_server = $(patsubst %.cpp,${DIR_OBJ}/%.o,$(notdir ${SRC_Server} ))
OBJ_client = $(patsubst %.cpp,${DIR_OBJ}/%.o,$(notdir ${SRC_Client} ))

TARGET_Server = tcp_server
TARGET_Client = tcp_client

BIN_TARGET_Server = ${DIR_BIN}/${TARGET_Server}
BIN_TARGET_Client = ${DIR_BIN}/${TARGET_Client}

TARGET = ${DIR_BIN}/${TARGET_Server}  ${DIR_BIN}/${TARGET_Client}
all: $(TARGET)
CFLAGS = -g -O2 -Wall -I${DIR_INC}

${DIR_OBJ}/%.o : ${SRC_Server} ${SRC_Client}
    @echo 开始编译文件
    $(CC) ${CFLAGS} -c $?
    -mv *.o $(DIR_OBJ)/
    @echo 编译文件完成

${BIN_TARGET_Client} : ${OBJ_client}
@echo 链接生成文件目标文件
${CC} ${CFLAGS} ${OBJ_client}  -o $@  

${BIN_TARGET_Server} : ${OBJ_server}
    @echo 链接生成文件目标文件
    ${CC} ${CFLAGS} ${OBJ_server}  -o $@  

.PHONY : clean run
clean:
    @echo 删除编译结果文件
    -rm -f ${DIR_OBJ}/*.o ${BIN_TARGET_Server} ${BIN_TARGET_Client}

run:
    @echo 执行文件
    ${BIN_TARGET}

-W 后加 -Wno-unused 可以屏蔽unused警告信息。
