The tool sounds cool but it seems that I have to buy it, so that's no 
option for me. So I tried to compile SDL myself. I have to say I'm to 
stupid for it. I tried to do the same thing as the makefile in 
powershell. After I hacked together some solution that worked dmc 
complained about missing Gl.h. It isn't there. So I added some MinGW to 
the include-path and then I get a bunch of errors in SDL without 
linenumbers. And anyways I am trying to compile it without MinGW, aren't 
I. Please, help me!
