some SDL linking problems

Question

so here's the problem I'm having. All of a sudden, implementing SDL just doesn't work anymore on vs 2013. To be more specific, anytime include the SDL standard header I get linker errors. I tried building my project with the following code:

#include <iostream>
#include <SDL.h>

SDL_Window *window;
SDL_GLContext context;

int main(int argc, char *argv[]){
    std::cout << "hello world" << std::endl;
    if (SDL_Init(SDL_INIT_EVERYTHING)){
        SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);
        window = SDL_CreateWindow("test", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 800, 600, SDL_WINDOW_OPENGL&SDL_WINDOW_SHOWN);
        context = SDL_GL_CreateContext(window);
    }
    SDL_Delay(20000);
    SDL_GL_DeleteContext(context);
    SDL_DestroyWindow(window);
    system("pause");
    return 0;
}

I get the following errors:

Error 1 error LNK2019: unresolved external symbol _SDL_CreateWindow referenced in function _SDL_main C:\Users\Nas\Documents\Visual Studio 2013\Projects\Open GL\Open GL\main.obj
Error 2 error LNK2019: unresolved external symbol _SDL_DestroyWindow referenced in function _SDL_main C:\Users\Nas\Documents\Visual Studio 2013\Projects\Open GL\Open GL\main.obj

Error 6 error LNK2019: unresolved external symbol _SDL_Delay referenced in function _SDL_main C:\Users\Nas\Documents\Visual Studio 2013\Projects\Open GL\Open GL\main.obj

Error 9 error LNK1120: 8 unresolved externals C:\Users\Nas\Documents\Visual Studio 2013\Projects\Open GL\Debug\Open GL.exe

any help is appreciated :)

here's a list of things I already tried:

undefining main ~> #undef main
changing my subsystem to both windows and console (neither worked)
Repeatedly cleaning and rebuilding my project.

where are you specifying the static SDL library to be linked with your project? — edition, Dec 11 '15 at 05:33

Did you link against the SDL.dll?

Here is explained how you do that.

Well, basically when you're using `LoadLibrary` you are linking... that's what DLL stands for DLL -> Dynamic Link Library. :D – lindebear Dec 11 '15 at 05:43
For the record I know what DLL stands for, and I know the difference between a statically linked library and a dynamically linked one. Yet, for some reason I was still stupid enough to forget to link the DLL. Thanks for helping me with this stupid blunder, really appreciate it :). – Nasir Jones Dec 11 '15 at 08:33
Well in that case I apologize for telling you again! haha :D – lindebear Dec 12 '15 at 03:29
