Hi,
I am still a happy user of this project and I was trying to expand to a new device. I can not build the xmega firmware anymore though. This is the error I am getting:

I am on an Arch VM and followed the instructions at https://github.com/ahtn/keyplus/tree/master/ports/xmega exactly.
@emilytrau I know you've always been very helpful in the past. Is there any chance you could check of the build still works for you? Thank you so much!
