Re: [cgkit-user] [cgkit-commits] CGkitinfo Error

[david v. <mis...@ga...>]

Oups... sorry for the commit-mail thing... And thanks Matthias for helping
me on that !

Well, to be exact, i had trouble installing the whole package, as well as
pygame, on my out of the box Osx with apple's compiled 2.5.1 python in it.
The .pkg of both cgkit and pygame didn't want to install because it was
needing a "System Python Install" ... The python installation folder in my
case was 
 1)     /System/Library/Frameworks/Python.framework/Versions/2.5/
 and i've seen that the .pkg was installing well with the existence of the
same path without the /System/ on front of it: 
 2)    /Library/Frameworks/Python.framework/Versions/2.5/
this is typically the path where activestate or pythonmac installs when
they're downloaded.

I've noticed something else: installing pyOpenGL, numpy and pyProtocols was
ok with no (visible) problem, and the lib were put by the installer in a
third folder:
 3)   /Library/Python/2.5/site-packages/

So i had the package of pygame and cgkit extract in the folder #2, and had
to move the files in the folder  #3, in order to had it load from the
python console..
I also downloaded the sources from cgkit, just for me to see. And here,
i've noticed two things:

(the python console is fired up from my basic home dir)
First, a simple call from the console to cgkitinfo raise an error:

    >>> import cgkitinfo
   Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    ImportError: No module named cgkitinfo

Second, i have neither the viewer.py or the render.py in the freshly ".pkg"
extracted folder in location #2 and copyied in location #3: I can only find
those two files in the source archive. So i just copyied those two files
from the source dir to the dir #3, just to be sure to not exec it from the
source dir (i've also deleted it)

I've made the viewer.py working after modifying the __init__ .py, but for
now the render.py still doesn't work with 3Delight (and a ton of error)

    Exporting main.rib...
    Traceback (most recent call last):
      File "/Library/Python/2.5/site-packages/render.py", line 361, in
<module>
        render.run()
      File "/Library/Python/2.5/site-packages/cgkit/tool.py", line 198, in

        self.action()
      File "/Library/Python/2.5/site-packages/render.py", line 237, in

        bakestvar = bakestvar
      File "/Library/Python/2.5/site-packages/cgkit/cmds.py", line 981, in
save
        exp.exportFile(os.path.basename(filename), **options)
      File "/Library/Python/2.5/site-packages/cgkit/ribexport.py", line
170, in exportFile
        explgt = protocols.adapt(obj, ILightSource)
      File "C:\cygwin\home\pje\PyProtocols\src/protocols/_speedups.pyx",
line 199, in _speedups.adapt
      File "C:\cygwin\home\pje\PyProtocols\src/protocols/_speedups.pyx",
line 188, in _speedups._adapt
    TypeError: exceptions must be strings, classes, or instances, not
AdaptationFailure

... The one with the "C:\cygwin..." worries me a bit as i'm on Osx...

Anyway, with my mod, viewer.py works. for render.py... well you see (and
it's a pitty as i wanted to user cgkit for renderman stuff). Does those
explanation ring the bell ? what have i done wrong ?
