I'm trying to build a simple SFML program, but I keep getting these errors when I build the program. I tried Google, but the errors were always different than mine. I have SFML statically linked, here's my linker input:

winmm.lib;sfml-system-s.lib;ws2_32.lib;sfml-network-s.lib;opengl32.lib;gdi32.lib;sfml-window-s.lib;freetype.lib;sfml-graphics-s.lib

I have the SFML_STATIC line as well. I'm not quite sure what the problem is.

Code:

#ifndef __IOSTREAM_H

#include <iostream>

#endif



#include "data/movement.h"

#include <SFML/Graphics.hpp>





int main()

{

    sf::RenderWindow mainw(sf::VideoMode(512, 512), "Window");



    while (mainw.isOpen())

    {

        sf::Event winEvent;

        while (mainw.pollEvent(winEvent)) 

        {

            if (winEvent.type == sf::Event::Closed)

            {

                mainw.close();

            } else;

            if (winEvent.type == sf::Event::KeyPressed) 

            {

                if (winEvent.key.code == sf::Keyboard::Up)

                {

                    upEvent();

                }

                else if (winEvent.key.code == sf::Keyboard::Down)

                {

                    downEvent();

                }

                else if (winEvent.key.code == sf::Keyboard::Left)

                {

                    leftEvent();

                }

                else if (winEvent.key.code == sf::Keyboard::Right)

                {

                    rightEvent();

                }

            }

        }

    } 



    return 0;

}

First I am going to link to SFML's tutorial page for Visual Studio linking.

But it looks like you only link the release versions. Make sure you use the Debug libs under the Debug configuration and the Release libs under the Release configuration. Each configuration needs setup individually.
