[SciPy-user] Re: SciPy-user digest, Vol 1 #201 - 7 msgs

Travis,

I tried this, and it does allow me to finish building, but why are there no 
files in the xplt directory (except for setup_xplt.py), when I can see them 
on the CVS page. I see that someone else had a similar problem to me, with 
the downloaded tarball.

Thanks for the tip. However....

I realized that I needed to get the full LAPACK installation (and therefore 
had to also build BLAS since I have no vendor-supplied version). My full 
LAPACK weighs in at a healthy 6MB, and I followed the procedures in the 
installation guide to replace ATLAS's wimpy version of LAPACK with the real 
one. So far, so good. Now the setup script runs to completion, but when I 
try to import scipy here's what happens:

% ~/bin/python
Python 2.1.1 (#1, Aug  9 2001, 11:10:31)
[GCC egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)] on linux2
Type "copyright", "credits" or "license" for more information.
 >>> import scipy
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
   File "/home/fgibbons/lib/python2.1/site-packages/scipy/__init__.py", 
line 36, in ?
     from scipy_base import *
   File "scipy_base/__init__.py", line 99, in ?
     import fastumath
ImportError: No module named fastumath

To summarize my setup, I'm using the following:

Python 2.1.1
Numeric 21.0
ATLAS 3.4.1
f2py 2.23.190...
gcc 2.95.4
g77 (0.5.25 20010319)
on a Debian Linux box.

Since I've had to go back and forth in the build process a few times, I 
wonder if I might be able to just do the equivalent of 'make clean' and 
start it fresh. I'm not very familiar with setup.py (why is this better 
than make?) - can anyone tell me how to do the equivalent of 'make clean'?

What is 'fastumath'? Where are the sources? How do I get them to build?

Thanks a lot for the tips so far - I feel like I'm close, and I'm drooling 
at the possibility of having LAPACK/BLAS power available from Python!
