[Pyobjc-dev] bootstrapping with execve in /bin/sh?

[Just v. R. <ju...@le...>]

Ok, ok, I take it all back about requiring Jaguar just so we can use
/usr/bin/python for bootstrapping...

This was Ronald's suggestion from a while back:

> sh?
> 
> #!/bin/bash
> 
> res=$(dirname $(dirname ${0}))/Resources
> main=${res}/main.py
> export PYTHONPATH
> PYTHONPATH=$res
> 
> exec /usr/local/bin/python ${main}
> # end of file

I've actually managed to make it sortof work (hey, I've never written a shell
script before! ;-).

But I'm running into a problem: the runtime can't find the path for the main
nib:

Traceback (most recent call last):
  File
"/Users/just/code/pyobjc/Examples/TableModel/build/TableModel.app/Contents/
Resources/TableModel.py", line 19, in ?
    NibClassBuilder.extractClasses("MainMenu")
  File "/usr/lib/python2.2/site-packages/AppKit/NibClassBuilder.py", line 128,
in extractClasses
    self._extractClassesFromNibFromBundle(nibName, bundle)
  File "/usr/lib/python2.2/site-packages/AppKit/NibClassBuilder.py", line 144,
in _extractClassesFromNibFromBundle
    raise NibLoaderError, ("Could not find nib named '%s' "
AppKit.NibClassBuilder.NibLoaderError: Could not find nib named 'MainMenu' in
bundle 'NSBundle </usr/bin> 

(I assume that if NibClassLoader.py wasn't used here, it would exit with a
similar message from NSApplicationMain().)

I'm not sure, but I _think_ it's because 'exec' in /bin/sh isn't exactly the
same as execve(). Does this sound plausible? If so, what _is_ the equivalent of
execve() in sh? Also: the exporting of PYTHONPATH doesn't work as written above:
os.environ doesn't show it.

Any clues? (googling for "execve" and "sh" only gives me hits for
execve("/bin/sh", ...); ;-)
