利用qmake生成Makefile文件

原文：http://blog.csdn.net/askeyes/article/details/8645101

虽说qt已经被诺基亚放弃，但是qt项目还是在进行，5.0已经出来了。

在linux下写程序，免不了要写Makefile文件，用automake，总感觉比较麻烦，linux人喜欢做麻烦的事，以显得风格迥异。

其实用qmake生成Makefile文件相当简单。

1 装好qmake工具

2 在源码工程目录下，运行qmake -project

这样会生成一个*.pro文件。

3 运行qmake -makefile *.pro，生成Makefile文件。

此Makefile文件，包含很多的qt的信息，如果工程中没有用到qt相关的库，那么可以删去。

例子:

一个工程目录下：

有三个目录，a，b，m。其中a目录下有a.c和a.h，b目录下b.c和b.h，m目录下main.c

a.c内容：

#include <stdio.h>

#include "a.h"

int a(void)

{

printf("call a!\n");

return 0;

}

a.h内容：

#ifndef __A_H

#define __A_H

int a(void);

#endif

－－－－－－－－－－－－－－－－－－－

b.c内容：

#include <stdio.h>

#include "b.h"

int b(void)

{

printf("call b!\n");

return 0;

}

b.h内容：

#ifndef __B_H

#define __B_H

int b(void);

#endif

－－－－－－－－－－－－－－－－－－－－

main.c内容：

#include <stdio.h>

#include "a.h"

#include "b.h"

int main(int argc, char** argv)

{

if(argc > 1)

{

printf("%s\n", argv[1]);

}

printf("Hello, Linux World!\n");

a();

b();

return 0;

}
