错误,错误,内存不足以及代码块中的SDL_ShowSimpleMessageBox未定义引用

所以我从代码块开始,并且正在网上学习教程,所以我做了一个有一个文件的空项目。

Largest: 444
Second largest: 44
Smallest: 1
Second smallest: 2

链接器设置:

#include <SDL.h>
#include <stdio.h>


//Screen dimension constants
const int SCREEN_WIDTH = 640;
const int SCREEN_HEIGHT = 480;

int main( int argc, char* args[] )
{
    //The window we'll be rendering to
    SDL_Window* window = NULL;

    //The surface contained by the window
    SDL_Surface* screenSurface = NULL;

    //Initialize SDL
    if( SDL_Init( SDL_INIT_VIDEO ) < 0 )
    {
        printf( "SDL could not initialize! SDL_Error: %s\n", SDL_GetError() );
    }
    else
    {
        //Create window
        window = SDL_CreateWindow( "SDL Tutorial", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, SCREEN_WIDTH, SCREEN_HEIGHT, SDL_WINDOW_SHOWN );
        if( window == NULL )
        {
            printf( "Window could not be created! SDL_Error: %s\n", SDL_GetError() );
        }
        else
        {
            //Get window surface
            screenSurface = SDL_GetWindowSurface( window );

            //Fill the surface white
            SDL_FillRect( screenSurface, NULL, SDL_MapRGB( screenSurface->format, 0xFF, 0xFF, 0xFF ) );

            //Update the surface
            SDL_UpdateWindowSurface( window );

            //Wait two seconds
            SDL_Delay( 2000 );
        }
    }

    //Destroy window
    SDL_DestroyWindow( window );

    //Quit SDL subsystems
    SDL_Quit();

    return 0;
}

我得到这个错误,

-lmingw32 -lSDL2main -lSDL2

我不确定这是内存错误,还是不确定的引用错误(如果是内存错误),我不知道为什么,因为其他较大的程序有足够的内存,并且不确定的引用在某处出错似乎不在我的代码中的代码... 任何帮助,将不胜感激。 :)

是的,我使用了错误的库,因此如果其他任何人遇到问题,请确保您为IDE下载了正确的文件。谢谢HolyBlackCat:)
