Hey there,
I currently can't compile nalgebra. When I try to do so, I get an internal compiler error:
broken MIR in DefId(0/0:567 ~ nalgebra[f626]::core[0]::matrix[0]:...
I've testet it with versions 0.14.4 (which ggez depends on) and 0.16.5 (latest version).
Travis seems to compile their stuff, so I think the error is somewhere on my system, but I have no clue where to look.
Does nalgebra compile on your system?
Thanks for referencing, this seems to be exactly what happened to my project
