Having trouble installing PIL in Snow Leopard

Question

I followed these instructions:

http://proteus-tech.com/blog/cwt/install-pil-in-snow-leopard/

And everything went as described.

However, at the end, I tried running:

python selftest.py

to verify that everything is working properly, but I get:

*** The _imaging C module is not installed

I then run the python interpreter and tried:

import _imaging

and get this error:

Traceback (most recent call last): File "", line 1, in ImportError: dlopen(/Library/Python/2.6/site-packages/PIL/_imaging.so, 2): Symbol not found: _jpeg_resync_to_restart Referenced from: /Library/Python/2.6/site-packages/PIL/_imaging.so Expected in: flat namespace in /Library/Python/2.6/site-packages/PIL/_imaging.so

This is on my first Mac, so apologize if I'm missing anything obvious, but any help you could provide would be greatly appreciated.

Thanks!

Answer 1

The problem happens because jpeglib is not available as part of standard MAC OS X distribution for Leopard and Snow Leopard.

The solution is as follows: - compile lib jpeg - make sure tha libjpeg62.dylib is available on your DYLD_LIBRARY_PATH (you might like to put it in places like /usr/local/lib)

Useful instructions are available here

Ok, got it working thanks to Shailesh's help. First, I ran this:

otool -L /Library/Python/2.6/site-packages/PIL/_imaging.so

to see where the dependencies were. I removed those references to libjpeg, and then recompiled libjpeg and PIL (following the instructions in the link below) and then everything worked.
