利用qmake生成Makefile文件

时间:2023-01-16 21:41:28

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;
}
-------------------
