Ouch!  Are you using an M1 Mac?  Is the crash happening in the Intel or Silicon code?

Let me know if you need any help with that.  Much thanks for any clues you can provide!

I was never able to build wxLua, so hard to say.  This was a couple of years ago so I forget
what the problem was.  Maybe things have improved since then but I really wanted to
minimize my dependence on wxWidgets.  This probably sounds very strange given that
Glu uses wxWidgets -- plus I've been using it since 2005 on a number of open source
projects (see the links to Golly, Ready and Ag at

There's a lot I like about wxWidgets, but a lot I don't like (especially the bugs and various
platform differences).  Glu is hopefully the last app I write using wxWidgets.  From now
on I hope to use only Lua to write games and other math/science projects that interest me.

Before starting on Glu I also looked at Love2D.  Very impressive, but it had a couple of
annoying bugs and lacked support for native open/save dialogs that were critical to the
kind of apps I wanted to write.
