Building with mingw on windows?

[onurhb]

Getting massive amount of errors when I am trying to compile on windows using mingw32. Should work out of the box #27 ?

I am using cmake to generate build files for mingw. Using msys shell to "make" it.

MinGW is not officially supported (#27 was a long time ago, and nobody has been actively maintaining mingw support). You are welcome to submit a PR which addresses these issues.

Ive managed to build nanogui by updating glad. I've created a PR.
