[visionegg] Re: _imagingtk error

Hi Gabriel,

I don't have the time to delve into this right now, but I think it's more likely a pygame issue -- the error message indicates something about threads. AFAIK PIL doesn't use threads, but I think some of the Mac OS X specific bits of pygame might. (The Vision Egg itself does not.)

Early next week I can take a look if you're still stumped...

Cheers!
Andrew

Hi, all, 

new issue:

Been trying to add GUI functionality to my scripts, but having problems getting
the GUI functions to work in OS X.

For example, the VisionEgg demo "drumDemoGUI.py" exits with the following error
message:

Fatal Python error: PyEval_SaveThread: NULL tstate
Abort trap

I've included the entire VisionEgg startup log at the end of this email.

I think it may be related to issues loading the Python Imaging Library, as
python reports the following error during VisionEgg initialization:

2005-01-26 23:11:36,718 (2333) INFO: No Vision Egg logo :( because of error
while trying to display image in GUI.GraphicsConfigurationWindow:
exceptions.ImportError: No module named _imagingtk

This only happens on our OS X (10.3, python 2.3) boxes.  The PC install of
VisionEgg works fine.

I've reinstalled the PIL as per the original install instructions and also via
FINK, no go.

I've tried reinstalling Tkintervia Package Manager only to get the following
error:

(TclTkAqua): This package needs to be installed manually (no Download-URL field)
(AppleInstalledPython): This package needs to be installed manually (no
Download-URL field)

Following the install instructions on the VisionEgg site, I realized that there
is no package called "_imagingtk.py*" installed on both our OS X boxes, whereas
our test PC has it installed in the correct \site-packages\PIL directory.

Can I assume that I will just need to rebuild PIL manually on our OS X boxes? Is there a clear-cut way to determine what is missing, since apparently
check-config.py thinks everything is ok? I've included the check-config.py
output at the end of this email.

cheers,
