Allegro 5 for C++ / Visual Studio Help

You made sure to put sdl.lib in the linker, right? Also, post your code; VC is terrible at error messages, most of the time, so it'd be easier to just check your code.

I used the code for the first Lazy Foo tutorial, the one called "Hello"

Code:

//Using SDL and standard IO
#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;
}
