[visionegg] Re: VisionEgg on Tiger

Hey Gabe,

I was able to get VisionEgg running on Tiger, but it didn't come together until after a bit of hacking around. I plan to formalize the process soon (and will possibly put together a .pkg file) when we upgrade the lab to Tiger.

I used MacEnthon to install VisionEgg's dependencies, but quickly noticed that the installation was bailing. Fortunately, all of the packages required by VisionEgg do work, and you can install them individually (using the .mpkg and .pkg files distributed with MacEnthon). I ran the following script, but I'm not sure if that had anything to do with getting things working: http://undefined.org/ python/#TigerPython23Compat

Hello all,

Have upgraded to Tiger on both a Powermac G5 and a Powerbook G4... Only the
G5 install is working, even after following the recommended upgrade steps
from the VE install web site, including downloading the TigerPython23Compat
patch.

Getting the following stack trace error when trying to run a test script on
the powerbook:

Have tried a manual reinstall (python setup.py install) from the cvs source,
no go.

Have even tried changing the darwin_maxpriority header file setting as
suggested in
http://www.freelists.org/archives/visionegg/06-2005/msg00003.html, no go.

I'm sure I'm making a simple mistake, but have spent too much time on it
already... Any ideas? I've included the check-config.py text dump at the
end of this email, cheers!
