Hey there!

I'm not sure what these errors are about. A couple of ideas I have to try are:

• Go to https://github.com/veandco/go-sdl2 and see if you can get their SDL2 examples to build on Windows / follow their build instructions. If you get those to work, SketchyMaze/ui should work as well.
• In case it's an SDL2 version issue, the version from here is known to work with this module: https://github.com/SketchyMaze/vendor/tree/master/mingw-libs

Per the cannot find -lSDL2 errors I would guess you don't have the SDL2 C libraries installed locally, and veandco/go-sdl2 may have some instructions how to set it up.

I haven't tried building go/ui from a Windows environment, but I'm able to cross-compile a Windows program from Linux by using the mingw SDL2 libraries and especially the version linked above (in my SketchyMaze/vendor git repo).
