LNK1561 entry point must be defined - SDL

I got a LNK1561 entry point must be defined error i tried somethings my self as stsyem settings to console and it still doesn't work. Here is my code for every class the SDl.h is from the SDL.h donwload page.

main.cpp:

#include <iostream>
#include "MainGame.h"

int main(int argc, char** argv) {

std::cout << "Enter any ket to quit...";
int a;
std::cin >> a;

return 0;

}

MainGame.cpp:

#include "MainGame.h"

MainGame::MainGame()
{

_window = nullptr;
_screenHeight = 1028;
_screenWidth = 768;

}


MainGame::~MainGame()
{
}

void MainGame::run() {
    InitSystems();
}

void MainGame::InitSystems() {
    SDL_Init(SDL_INIT_EVERYTHING);

    _window = SDL_CreateWindow("title", SDL_WINDOWPOS_CENTERED, 
    SDL_WINDOWPOS_CENTERED, 1028, 768, SDL_WINDOW_OPENGL);
    }

MainGame.h:

#pragma once

#include <SDL/SDL.h>

class MainGame
{
public:
    MainGame();
    ~MainGame();

    void run();

    void InitSystems();

private:
    SDL_Window* _window;
    int _screenWidth;
    int _screenHeight;
};

Allt his code is to open an Windowed frame on your computer en open an console with the text Press Any ket to quit... If i remove the SDL.h include and the SDL code it all works if i put the include back and not the SDL code it gives the error again.

Have you tried using MainGame in your main function? Chances that the compiler assumes that it is never used and you do not get the #include <SDL/SDL.h> directive to work. Also, consider changing #include <SDL/SDL.h> to #include "SDL/SDL.h".

Also you might consider using SDL_SetMainReady for the cases that you are not using SDL_Main as the entry point.
