[reportlab-users] Problem on Mac OSX

[Andy Robinson]

I think this is a problem with the specific copy of the Python Imaging
Library you have installed on your Mac OS.  On many platforms, PIL is
compiled with jpeg support.  It seems your PIL isn't.  We also had
this from a customer on Mac OS last week.

Can anyone who knows Mac OS well recommend what versions of PIL to
install, or what options are needed to recompile it with JPEG support?

On your second question, we don't normally run scripts from within an
interactive prompt.
If you want to, you need to run the same code which is at the bottom
of that script e.g.


>>> import os

>>> os.chdir('c:\\code\\reportlab\\test')

>>> import unittest

>>> import test_pdfgen_general

>>> unittest.TextTestRunner().run(test_pdfgen_general.makeSuite())

.
