[SciPy-user] scipy install errors

[Alastair Basden]

Hi,

Thanks for the various responses.

Have tried installing numpy/scipy with the svn versions as suggested, 
using 
python setup.py config_fc --fcompiler=gnu95 build

This has worked for numpy, but not for scipy:

If I try the scipy installation with just setup.py build, it seems to 
work, but then in python:
>>import scipy.special
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File 
"/data/hamilton/dph1agb/lib/python2.5/site-packages/scipy/special/__init__.py", 
line 8, in <module>
    from basic import *
  File 
"/data/hamilton/dph1agb/lib/python2.5/site-packages/scipy/special/basic.py", 
line 8, in <module>
    from _cephes import *
ImportError: 
/data/hamilton/dph1agb/lib/python2.5/site-packages/scipy/special/_cephes.so: 
undefined symbol: _gfortran_filename

So (not surprisingly) it seems to need the gfortran specified...


Note - using the svn numpy and the scipy0.6, the scipy.special.kv function 
is still behaving incorrectly, so it is a problem with scipy, not numpy (I 
had wondered whether it was the ufunc interface or something).

Thanks...

Platform is Suse 10.0 on AMD 64 processors.  lapack/atlas has been 
compiled by me.
