Adding any actors like canvas, polygon, rectangle...etc. results in a segmentation fault

[Victor Chen]

Hi! I'm trying LUZ on Ubuntu 12.04, and every time I try to add
an actor, such as canvas, polygon, rectangle...etc. I get a segmentation
fault. Here is the command line...output:
./luz_editor.rb

Thanks!

Thanks for the report!

 ./engine/actor.rb:140: [BUG] Segmentation fault

Line 140 is calling an OpenGL display list to draw the actor's polygon. I've never seen a segfault on that line before.

Do other OpenGL apps work for you?

Victor, did you download gtkglext.so from the URL provided, or somewhere else?

This report seems related:
https://github.com/lighttroupe/luz/issues/3

They got a custom 64-bit gtkglext.so from kxstudio.
