IED: Visual Studio Express 2012 - 64bit
SMFL Version: 2.0 - Visual C++ 11 (2012) - 64 bits

Previously, I had a development version of SFML - 2.0 working with VS 2012 by using CMake, but the new version of SFML does not contain CMakeList.txt and should support VS 2012 by default.

I followed the instructions perfectly. I have everything statically linked correctly, I tried dynamically linking, but recieved the same errors. I have looked over the forums and have tried several things to try and fix this. Please help.

#include <SFML/Graphics.hpp>
#include <iostream>

int main()
{
        sf::RenderWindow window(sf::VideoMode(800, 600), "Game");

        while(window.isOpen())
        {
                sf::Event event;

                while(window.pollEvent(event))
                {
                        if(event.type == sf::Event::Closed)
                        {
                                window.close();
                        }
                }

                window.display();

                window.clear();
        }

        return 0;
}

This is the exactly same code I have used in the development versions of SFML - 2.0 which worked perfectly.

If I am missing something or there is a really easy fix that I cannot see than I apologize, but I would really like to get this setup and working.

Make sure that SFML_STATIC isn't defined when linking dynamically.

If what eXpl0it3er said wasn't the problem, maybe you could try  using the precompiled binaries?

SFML_STATIC is not the problem I have used it correctly. Thank you for the idea.

Threads are not removed when the problem is solved. Instead, you could state how you solved the problem, for people that stumble across this thread in the future ;)

You have very high expectations. Judging from the threads that are started all the time, either they don't go to page 2 or they couldn't find the search button. I've tried to minimize this by writing a more or less useful FAQ, but since I can't tell how many people view it, I can't determine if it is directly correlated to the decline of questions that were answered several days in the past.

Also, I assume Harris attributed his problem to something that is not specific to SFML or programming in general and as such didn't deem the solution worthy to be written down here.

Still, I agree that the thread shouldn't be deleted, but a forum really isn't the right place for anything other than discussions that are useful to everybody. This of course assuming that people actually care to read what has been written ;).
SFGUI # SFNUL # GLS # Wyrm <- Why do I waste my time on such a useless project? Because I am awesome (first meaning).

It sounds like he was using the precompiled binaries (since he said the new version would support VS2012 "by default"). My guess would be that because he has a 64-bit development environment, he was trying to build a 32-bit application against 64-bit libraries, which won't work.

For anyone else having this problem, it's worth remembering when you download the libraries that the Visual Studio x (or whatever) part refers to your development platform, but the 32-bit vs. 64-bit refers to your target platform. Your development platform is probably (these days) 64-bit, but your target platform is still likely to be 32-bit unless you have a special reason to need a 64-bit program, so download the 32-bit binaries. (It's worth noting that neither the official tutorial nor any unofficial tutorial I've seen mentions this - maybe it's supposed to be obvious?)

At least, I was having this problem (though on VS2008) when I was stupidly using 64-bit binaries, and it went away when I switched to 32-bit binaries, so I guess that was the reason, although you would more expect this problem in that case.
