Hello guys, I'm sorry if this has been asked before, but I'm having a heck
of a time, probably putting 16 hours of trying on this, and Google and the
archive have been no help so far.
I'm using wxLua on OSX10.5 and attempting to get a "Hello world" type
program working on wxGLCanvas().
Basic problem:
- Have my own custom wxWindows program, running as an OSX app. Using a
wxLua interpreter.
- Used the wxLua binding system to create rudimentary OpenGL bindings
(I've tried other pre-made GL bindings, but those approaches but got crashes
when dynamic libraries were being loaded that I couldn't track down).
- Linked against the stock OSX OpenGL.framework.
- Created a window in lua, added a wxGLContext.
Result:
- It shows up grey, no rendering.
Any help is appreciated. I can provide any further information that might
be needed.
