Hi,

I’m attempting to bring Luz Studio[1][2] to Ubuntu 11.10 and I’m  
having some GL problems.

It seems ‘gtkglext’ is missing, and without that file, Gtk::GL,  
Gdk::GLConfig and perhaps other modules are missing, and Luz won’t  
start.

I see in the change log that GtkGLExt was dropped recently, but I’m  
not clear why.

Should ruby-gtk apps be able to access OpenGL with these bindings?

Any help would be most appreciated. Relevant bug.[3]

thanks!  
-Ian

We dropped it because nobody can maintain it.  
Sorry.

## Thanks,

Hi Kou,

What sort of work is needed to maintain the GtkGLExt bindings?

They appear to be quite small, under 1k lines of C according to the  
‘sloccount’ tool.

Is the difficulty in porting it to Gtk3, or is there another reason?

I would like to help maintain them, as they are a dependency of Luz.

I’m also considering bringing the GtkGLExt bindings into the Luz  
project. Please let me know if you think that would be a better  
option.

best,  
-Ian

Here are some works:

- Reply bug reports.
- Release new versions.

The best diffculty is that GtkGLExt isn’t maintained…

OK. I suggest that you maintain it as a gem out of the  
Ruby-GNOME2 project. If you want to create a repository  
under [https://github.com/ruby-gnome2/](https://github.com/ruby-gnome2/), I’ll create it.  
What about this idea?

## Thanks,
