pyglet segfaults on FreeBSD 8.0/amd64/nVidia

2010-04-15 Thread Giuseppe Pagnoni 
Hi Michael,

thanks for replying.  Unfortunately changing the driver to the nv one does 
not work since nv does not support GLX which is required by pyglet.  I 
appreciate your suggestion, though.

cheers,
   giuseppe

pyglet segfaults on FreeBSD 8.0/amd64/nVidia

2010-04-14 Thread Giuseppe Pagnoni 
Hello,

First of all, let me apologize for the re- and cross-posting , but
after a couple of weeks scouring the web and forums to no avail, I
thought I would try again and query the FreeBSD mother source...

I installed pyglet from the ports (latest version as of yesterday,
py26-pyglet-1.1.2_1) on a FreeBSD 8.0 amd64 box, running the latest
version of the ports' nvidia driver (nvidia-driver-195.36.15).  I
found that I cannot use either font.Text or text.label without causing
segfaults.  Here is some sample code that makes python crash:

- SNIPPET 1
import pyglet
luxi = pyglet.font.load('Luxi Sans', 14)
---   SEGMENTATION FAULT

- SNIPPET 2
import pyglet
window = pyglet.window.Window()
label = pyglet.text.Label('Hello, world',
   font_name='Luxi Sans',
   font_size=36,
   x=window.width//2,
   y=window.height//2,
   anchor_x='center',
   anchor_y='center')
---   SEGMENTATION FAULT

It seems that the problem arises already at the stage of font loading.
I am not at all a python expert, perhaps somebody can suggest a
way to narrow down the problem?

Here is some more information on my system reported by a routine
included in a python package (PsychoPy) I am trying to use:

I'm not a coder, but possibly this may help: 

http://pyglet.org/doc/api/index.html

Then look at pyglet.font and pyglet.font.base for example purposes.

To drive a wedge you might consider as an experiment temporarily replacing 
the Nvidia driver in xorg.cong with the nv driver. If same problem, it may 
be confirming the problem is not an interaction with a video display driver 
but rather the Python coding itself. Notice the different approach in the 
doc example(s).

I'm not really a coder and don't know a whole lot about Python, but since 
this seems to have been a problem to you for a while now I thought maybe I'd 
toss out my ideas. YMMV  :-)
