I was able to compile the project, mingw is such a mess, what the hell.
Question:
I built a DLL, which links sfml-graphics-s, etc.
That means that linking against that dll cuts the need to link for sfml right?
In Visual studio this works fine, sfml is inside the DLL file, and it works without linking sfml for every app which uses my dll.
I wrote a test application and it says undefined reference to the sfml stuff, even tough i link the DLL, whats wrong?
