Ok, so I continued my adventures with Pyglet...
First of all, I cannot even run gl_info.py on my machine... it gives me the
same error...
I have a Ubuntu 9.04 (i386 version) virual machine with my Fedora 11 x86_64
running as Guest, and Pyglet ran just fine (sluggish, but at least it ran)
on that machine... that made me become very mad!
So today I started debugging pyglet's code for my simple code:
# -*- coding: utf-8 -*-
import pyglet
pyglet.options['shadow_window'] = False
#pyglet.window.get_platform().get_default_display().get_default_screen().get_best_config()
window = pyglet.window.Window()
I started tracing the source code (using pdb) starting just before the
"window = pyglet.window.Window()" line on my code.
After slowly inspecting the code (and skipping other parts that I didn't
care for) I got to this lines in the
/usr/lib/python2.6/site-packages/pyglet/window/xlib/__init__py file (from
line line 265):
if have_13:
elements = c_int()
configs = glx.glXChooseFBConfig(x_display, self._x_screen_id,
attrib_list, byref(elements))
if not configs:
return []
When printing the value of configs I get:
<pyglet.gl.glx.LP_LP_struct___GLXFBConfigRec object at 0x16dc050>
But I saw that the debugger evaluated the "if not configs" line and then
returned []!
So, before the debugger returned from this level, I wrote this in the pdb
prompt:
(Pdb) not configs
And it printed "True" as a result!
What?! Inspected the config variable and then printed the only "normal"
attribute, "contents". printing configs.contents gave me the following:
*** ValueError: NULL pointer access
I think my error can be here... I don't have a clear idea on what I can do
next... whether this is a 64 bit issue or... a missing library... let me
paste the values of other maybe relevant variables in the local context:
attrs = [5, 1, 12, 24, 32786, True, 0, 0]
attrib_list = <pyglet.window.xlib.c_int_Array_8 object at 0x16dc200>
elements = c_int(0)
x_display = <pyglet.gl.glx.LP_struct__XDisplay object at 0x16e9cb0>
Although all those structs don't look so useful pasted here :D
Further comparisons with my Ubuntu virtualmachine gives me that the
self.display.info.get_server_version() returns different strings
'1.4' on Host Fedora
'1.3' on Guest Ubuntu
thus...
have_13 is True on Fedora and False on Ubuntu... so the path that is
executed by both machines is different... further comparisons will reveal
nothing :(...
So... err... any ideas guys?
Thank you,
Federico
