Hello, @E37. Yeah as lolpro11 said the wiki asks you to use Cygwin so that's why I chose it. I'm new to the Ndless scene and haven't dabbled much in C or C++ before that so I'm not actually sure what WSL is. I'll look into it though and see if it helps with anything, thanks. Also, the wiki said that on windows you had to fix a few symlinks in the files before building. I only fixed the one it mentioned with zehn.h, but yeah that's probably why it's not running. I have a Manjaro partition so I'll see if that gives me better luck.
