开始学linux。我练习写的第一个带子目录的makefile文件。

1。建立文件夹 wulong

wulong中含 三个文件夹 include source pro 和makefile文件。

include 中包含 hai.h头文件。

source 中包含 hello.c文件。

pro 中包含 haia.c haib.c文件。

makefile文件内容有两种写法：

makefile 第一种写法：

／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

CC=gcc ＃选择编译器类型为gcc

VPATH= include : pr : source #列明文件存放目录

hello: hello.o haia.o haib.o

$(CC) -o hello hello.o haia.o haib.o

hello.o:hello.c hai.h

$(CC) -c hello.c

haia.o: haia.c hai.h

$(CC) -c haia.c

haib.o: haib.c hai.h

$(CC) -c haib.c

.PHONY: clean

clean:

rm hello $(obj)

／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

makefile第二种写法(简化版)：

／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

CC=gcc #选择编译种类

VPATH= include : pr : source #在include pr source 三目录下查找文件

obj= hello.o haia.o haib.o ＃

hello:$(obj) ＃

$(CC) -o hello $(obj)

$(obj): hai.h

.PHONY: clean

clean:

rm hello $(obj)

／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

hai.h文件内容为：

／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

#include "stdio.h"

extern void haiprinta();

extern void haiprintb();

／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

hello.c内容为：

／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

#include "../include/hai.h"

int main(void)

{

haiprinta();

haiprintb();

return 0;

}

／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊

haia.c内容为：

／／＊＊＊＊＊＊＊＊＊＊＊＊

#include "../include/hai.h"

void haiprinta()

{

printf("hai aaaaaaaaaa\n");

}

／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊

haib.c内容为：

／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊

#include "../include/hai.h"

void haiprintb()

{

printf("haib bbbbbbbbbbbbbb\n");

}

／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

2。make 调用makefile生成 可执行文件 hello

3. 运行 hello显示打印结果：

[HAI@localhost wulong]$ ./hello

hai aaaaaaaaaa

haib bbbbbbbbbbbbbb

[HAI@localhost wulong]$

到此结束，恭喜！
