无法使用 Dev-C++ 编译简单的 SDL 程序

Question

在您阅读之前就知道我不是英语，所以希望我不会在这里拼写错误。反正。我试图编译我的第一个 SDL 程序，所以我按照在线教程安装了 SDL2 库。我使用的代码（从 here min 13:00 复制）是这样的：

#include <iostream>
#include <SDL2/SDL.h>
using namespace std;

int main(void){

    if(SDL_Init(SDL_INIT_VIDEO) < 0) {
        cout << "SDL init failed.\n";
        return 1;
    }

    cout << "SDL init succeeded";
    SDL_Quit();


    return 0;
}

我得到的错误是这个

C:\Users\raffaele.ciotola\Desktop\Marco & Lory\Lorenzo\Dev-Cpp\SDL2-2.0.12\x86_64-w64-mingw32\lib\libSDL2main.a(SDL_windows_main.o) In function `main_getcmdline':
71      s:\rs\valve\release\SDL\SDL2-2.0.12-source\src\main\windows\SDL_windows_main.c  undefined reference to `SDL_main'

25      C:\Users\raffaele.ciotola\Desktop\Marco & Lory\Lorenzo\Dev-Cpp\Programs\SDL_\Makefile.win   recipe for target 'SDL_.exe' failed

我尝试运行我的 Dev-Cpp.exe 管理员，因为安装文件夹在桌面上，但这并没有解决问题。

Makefile（不管它是什么，我没有最起码的想法）就是这个。如果需要的话¯_(ツ)_/¯.

如果您需要任何其他信息，请询问。谢谢。

Answer 1

SDL 用自己的函数劫持 main 函数以进行一些初始设置。然后它调用您编写的任何内容作为 main 函数。因为它正在调用您的 main 函数，所以它希望以特定方式定义它。

试试这个，它应该可以解决您遇到的错误：

int main(int argc, char* args[])
{
    // whatever
    return 0;
}
