无法使用 Dev-C++ 编译简单的 SDL 程序

Question

在你阅读之前，要知道我不是英国人，所以希望我不会在这里拼写错误。无论如何我试图编译我的第一个SDL程序，所以我遵循在线教程安装SDL2库。我使用的代码(从这里复制min13:00(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:Usersraffaele.ciotolaDesktopMarco & LoryLorenzoDev-CppSDL2-2.0.12x86_64-w64-mingw32liblibSDL2main.a(SDL_windows_main.o) In function `main_getcmdline':

我试着在管理员上运行我的Dev-Cpp.exe，因为安装文件夹在桌面上，但这并没有解决问题。

Makefile(不管是什么，我都不知道(就是这样。如果需要_(ツ)_/。

SDL用自己的函数劫持main，以便进行一些初始设置。然后，它将调用您编写的任何内容作为main函数。因为它正在调用main函数，所以它希望以特定的方式定义它。

试试这个，它应该可以解决你遇到的错误：

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