I'm trying to learn to make games with SDL. My book teaches SDL1.2.3 and I can't get it to work on Visual Studio. Can anyone help? My errors:

Question

#include "sdl.h"
#include <stdio.h>
#include <stdlib.h>

SDL_Surface* g_pMainSurface = NULL;
SDL_Event g_Event;

int main(int argc, char* argv[])
{
    if (SDL_Init(SDL_INIT_VIDEO)==-1)
    {
        fprintf(stderr, "Could not initialize SDL!\n");
        exit(1);
    }

    else
    {
        fprintf(stdout, "SDL initialized properly!\n");
        atexit(SDL_Quit);
    }

    g_pMainSurface = SDL_SetVideoMode(640, 480, 0, SDL_ANYFORMAT);

    if (!g_pMainSurface)
    {
        fprintf(stderr, "Could not creat main surface!\n");
        exit(1);
    }

    for (;;)
    {
        if (SDL_WaitEvent(&g_Event) == 0)
        {
            exit(1);
        }

        if (g_Event.type == SDL_QUIT)
        {
            fprintf(stdout, "Quit event has occurred.\n");
            break;
        }

    }

    fprintf(stdout, "Terminating program normally.\n");
    return (0);
}

That page doesn't help me at all. There's too much info on who knows what — Andrew Parker, Nov 30 '16 at 03:48

Your project is likely missing the SDL static library references. Open your project properties window, go to the Linker Settings, and add the paths to your SDL static library files.

You mean sdl.lib and sdlmain.lib? Because I already have those. – Andrew Parker Nov 30 '16 at 02:40

You should learn sdl 2.0 , sdl 1 is out of age ! btw try to add :

pragma comment(lib,"SDL.lib")
