[Image-SIG] bug: selftest.py fails

[Mark Sienkiewicz]

http://www.pythonware.com/products/pil/ says this is the place to send 
bug reports for PIL.


Imaging-1.1.6 selftest.py fails, even after a successful build.

Observed on
    Solaris 10, Python 2.5.2, GCC 4.1.1
    Red Hat Enterprise 4 Linux, Python 2.5.1, GCC 3.4.6

# location of correct libraries
% setenv LDFLAGS -L/usr/stsci/Python-2.5.2/lib/ 

% python setup.py build

% python selftest.py
Traceback (most recent call last)
  File "selftest.py", line 11, in <module>
    import ImageMath
  File "PIL/ImageMath.py", line 19, in <module>
    import _imagingmath
ImportError: No module named _imagingmath

Looking in selftest.py, it appears that it expects to find _imagingmath 
by inserting "." and "PIL" on sys.path, but _imagingmath is not in 
either of those places.


% find . -name '_imagingmath*'
./_imagingmath.c
./build/lib.solaris-2.10-sun4u-2.5/_imagingmath.so
./build/temp.solaris-2.10-sun4u-2.5/_imagingmath.o


You can make it work by

% python setup.py install --install-lib=$wherever
% setenv PYTHONPATH $wherever
% rm -rf PIL
% ln -s $wherever/PIL .
% python selftest.py


I install too much software to read all the mailing lists, so if you 
have questions please contact me directly.
