Ok I am creating a graphics engine and I want to distribute by Static Linked Libs and I am using Dev-C++ as my ide. My engine uses SDL internally for window management. So I decided I want to test it as a static linked library. I developed the window manager portion of the engine using a windows win32 project for easy testing and it works. Now when I put the window manager header and the cpp that acompanies it into the static lib and lnk up sdl to it and such to compile it compiles. But when I go to test it in another app i link up the sdl libs and my static lib and it just blows chunks and will not compile. what is going on :S could it be mingw that is not likeing things or what.
