Bug 34391 – Examples in pygtkglext need PyOpenGL, PyOpenGL not in the dependency-list of pygtkglext-1.0.0.ebuild, also other minor issues with the examples

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Toon Verstraelen 2003-11-26 01:21:45 UTC]

There are af few problems with the examples that are installed with the
pygtkglext-1.0.0.ebuild. The major problem is that all these examples need
PyOpenGL, and that PyOpenGL is not mentioned in the dependencies of pygtkglext.
If PyOpenGL is installed manualy, most of the examples work.

Still some examples don't work when PyOpenGL is installed:

* color.py, gives the following error output
OpenGL extension version - 1.3
 
Traceback (most recent call last):
  File "color.py", line 175, in ?
    app = ColorManagementDemo()
  File "color.py", line 40, in __init__
    self.glconfig = gtk.gdkgl.Config(mode=self.display_mode)
gtk.gdkgl.NoMatches: no frame buffer configurations match the specified attributes

* pixmap.py and pixmap-mixed.py make my nvidia card (Riva TNT2 M64) crash, no
problems with ATI Rage128

* NeHe6Multi.py needs wall.png
Traceback (most recent call last):
  File "/usr/lib/python2.2/site-packages/gtk-2.0/gtk/gtkgl/apputils.py", line
236, in __realize
    self.glscene.init()
  File "NeHe6Multi.py", line 99, in init
    self.__loadTexture('Wall.png')
  File "NeHe6Multi.py", line 72, in __loadTexture
    image = gtk.gdk.pixbuf_new_from_file(fileName)
gobject.GError: Openen van bestand 'Wall.png' mislukt: Onbekend bestand of map


Reproducible: Always
Steps to Reproduce:
1. cd /usr/share/doc/pygtkglext/examples
2. "choose an example"
3. python someexample.py

Actual Results:  
none of the examples work (give error messages and quit) when PyOpenGL is not
installed. When PyOpenGL is installed still having troubles with four
examplescripts (see details)

Expected Results:  
show some of the pygtkglext features

it does need an rdep on pyopengl to be useful yep

The gdk problem may be a bug or just a bad demo.

The second non-working demo is due to a texture image missing, make sure it is available.

So i'd say adding the PyOpenGL dep should be sufficient.

[Comment 2 foser (RETIRED) 2003-12-06 05:43:44 UTC]

while i was at it, added dev-python/PyOpenGL to the deps. Marked 1.0.0 x86 & added 1.0.1 to ~x86.

I'm affraid the bug confirmation must be some kind of mistake?
