I've just installed matplotlib on a 64 bit server running Suse Linux
Enterprise Server 9. I followed the instructions on the Installing
section from the webpage and everything seemed to install fine using the
defaults. I installed the latest version of Numpy, 1.0.1, then
proceeded to install matplotlib. (I had the devel packages of freetype,
libpng, and zlib installed.) I don't need a GUI Backend so I wasn't
worried about getting them installed properly. Everything seems fine, I
can import numpy and matplotlib into python. However, I run into this
problem when trying to do an import. Here's the sample code:
#!/usr/bin/env python
import os
import tempfile
import matplotlib
matplotlib.use('Agg') # force the antigrain backend
from matplotlib import rc
from matplotlib.backends.backend_agg import FigureCanvasAgg
from matplotlib.figure import Figure
from matplotlib.cbook import iterable
import matplotlib.numerix as nx
***snip***
And here is the output:
$ python test_matlib.py
The import of the numpy version of the _image module,
_ns_image, failed. This is is either because numpy was
unavailable when matplotlib was compiled, because a dependency of
_ns_image could not be satisfied, or because the build flag for
this module was turned off in setup.py. If it appears that
_ns_image was not built, make sure you have a working copy of
numpy and then re-install matplotlib. Otherwise, the following
traceback gives more details:
Traceback (most recent call last):
File "test_matlib.py", line 7, in ?

ImportError:
/usr/local/lib/python2.3/site-packages/matplotlib/_ns_image.so:
undefined symbol: _ZNSs4_Rep20_S_empty_rep_storageE
$
It seems like it's something very simple, but I can't seem to find what
went wrong. Anybody have any ideas??
Thanks
Josh
