I was following this tutorial, and I got to the part where it says to download SDL2-devel-2.0.9-mingw.tar.gz, but it doesn't say what I'm actually supposed to do with it. I feel like it's supposed to be obvious, but I'm a bit inexperienced with this kind of thing. I'd be more than willing to learn, though.
I tried that, but it still failed at "Checking for C library SDL2main". I managed to open the file using 7zip and somehow get the correct libraries out of it anyway, I think, but now it just stops somewhere else.
