Hello!
I am trying to run an image processing script on a new server under CentOS
5.4. I have compiled and installed PIL 1.1.7 to run with Python 2.7.1. The
compile went fine. All libraries (except TKInter) were found. All 57 tests
were passed by the test script.
When I try to run my script, however, I get the following error:
IOError: decoder zip not available
I presume that this either has to do with zlib or libjpeg but, as I said,
these libraries are installed and have been successfully used by other apps
on the server such as php 5.3.3 and ImageMagick.
Can someone help me find out what is not working and how to fix it?
I have confirmed that sys.path is looking in the right directories for the
libraries. I have also confirmed, by enabling verbose mode and importing the
Image module in IDLE.
Everything seems to look right but, still, it cannot find decoder zip. Here
is the output from the script I am using:
The python sys path is:
['/usr/local/mcutil/haven/minecraft-overviewer', '/usr/local/lib/python2.7',

I have re-installed the zlib and zlib-devel packages via yum with no effect.
I have rebuilt PIL several times and received positive results from the
build process but no change in behavior. (Here is a copy of the output of
setup.py:
[r...@mc2 Imaging-1.1.7]# python setup.py install

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.

I have scoured dozens of threads relating to the same problem. Most of them
yeilded terse, dummy answers like not having the devel packages installed
for the dependencies. This is obviously not the case here.

I also tried digging through the archives of this mailing list but I cannot
find a search tool. I went back several weeks, chronologically and did not
find any mention of this error message. My apologies if it is here somewhere
and I did not know how to find it.
Any help with where to look, how to troubleshoot, or even an answer would be
greatly appreciated.
Thanks in advance!
Hitting his head against the wall,
Adam :)
