[Image-SIG] Problem with jpeg decoder and PIL

[Jack Wu]

Hi

I'm specifically having problems with the JPEG support on OSX 10.3 PPC.
I got Fink to install jpeglib

I ran PIL's setup.py with the automatic paths i.e. '*ROOT = None'
(should automatically use
'/sw' due to fink)

-----------------------------
running install
running build
running build_py
running build_ext

PIL 1.1.5 BUILD SUMMARY
--------------------------------------------------------------------
version       1.1.5
platform      darwin 2.4.1 (#2, Mar 31 2005, 00:05:10)
              [GCC 3.3 20030304 (Apple Computer, Inc. build 1666)]
--------------------------------------------------------------------
*** TKINTER support not available
--- JPEG support ok
--- ZLIB (PNG/ZIP) support ok
*** FREETYPE2 support not available
--------------------------------------------------------------------
To add a missing option, make sure you have the required
library, and set the corresponding ROOT variable in the
setup.py script.

To check the build, run the selftest.py script.

Ok, but then i ran the self test and apparenlty doesn't work:
python selftest.py
*****************************************************************
Failure in example: _info(Image.open("Images/lena.jpg"))
from line #24 of selftest.testimage
Exception raised:

    raise IOError("decoder %s not available" % decoder_name)
IOError: decoder jpeg not available
1 items had failures:

*** 1 tests of 55 failed.




I also tried building the jpegLib (successfull) and adding that path
('/usr/local/lib') to the JPEGROOT = "" line in the setup.py, and
resetup PIL.  This has same results as above.
