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！
