linux下编译生成windows程序

arch下安装MinGW

yaourt -S mingw32-binutils mingw32-gcc mingw32-runtime

会生成对应的编译工具，在我的本本上是：

i486-mingw32-gcc i486-mingw32-g++

代码：

#include <stdio.h>

int swap_add(int *xp, int *yp)
{
    int x = *xp;
    int y = *yp;

    *xp = y;
    *yp = x;

    return x + y;
}

int caller()
{
    int arg1 = 1;
    int arg2 = 2;
    int sum = swap_add(&arg1, &arg2);
    int diff = arg1 - arg2;

    printf("swap_add: %d\n", sum);

    return sum * diff;
}

int main()
{
    printf("caller: %d\n", caller());

    return 0;
}


编译：

i486-mingw32-gcc -o swap_add.exe swap_add.c

运行：

wine swap_add.exe

结果：

swap_add: 3

caller:   3
