Package: python-scipy
Version: 0.6.0-1
Severity: serious

Dear SciPy maintainers,

SciPy 0.6.0 gives me this error when I try plotting with matplotlib:
<error>
% python p.py
Traceback (most recent call last):
File "plotit.py", line 3, in ?
from scipy import *
File "/usr/lib/python2.4/site-packages/scipy/fftpack/__init__.py", line 10, in ?
from basic import *
File "/usr/lib/python2.4/site-packages/scipy/fftpack/basic.py", line 13, in ?
import _fftpack as fftpack
ImportError: /usr/lib/python2.4/site-packages/scipy/fftpack/_fftpack.so: undefined symbol: zfftnd_fftw
</error>

The source file is this:
<code>
from scipy import *
from pylab import *

figure(figsize=(9,6))
plot([1,2,3],[4,5,6])
show()
</code>

Needless to say, SciPy 0.5.2 doesn't give this error. I couldn't zero
in on the error. Could you please look into where the problem could
be?

Thanks!

Kumar

Subject: fftpack/_fftpack.so: undefined symbol: zfftnd_fftw - FIX with fftw3

Date: Wed, 26 Sep 2007 15:18:34 +0200

I have just installed fftw3-dev and recompiled python-scipy using
dpkg-buildpackage.

This fixes the bug.
python-scipy should therefore depend and build-depend on
fftw3 and fftw3-dev, respectively, instead of fftw2 and fftw2-dev.

I hope this helps.
