[SciPy-user] Sparse Matrices (SciPy or elsewhere)?

[Costas Malamas]

Well, I need this to build a complicated prototype --I need Sparse to work, 
but not that well; if the prototype works, then things will change :-)

I've tried two different approaches:
1) Tried to compile SciPy CVS on current Cygwin (gcc 3.2, python 2.2.1).  I 
got ATLAS and LAPACK and all of SciPy compiling fine, but not sparse.  I 
worked around the last error I posted on this list, but then I run into 
symbol issues and gave up.

2) I've now tried to compile SciPy CVS using gcc-mingw as specified on the 
website.  I am running into the issue that my ATLAS and LAPACK are linked 
against another python (Cygwin's 2.2.1, whereas I am running 2.1 win32 on my 
box for another project).  I downloaded pre-built ATLAS but I don't know if 
this will work, since it's probably built with another compiler (are there 
any ABI issues w/ ATLAS??; I am guessing not, but I'd like to be sure)

If I go with (2), can I use pre-built ATLAS and LAPACK?

Also, how did you compile sparse on Linux? with its makefile (which looks a 
bit out-of-date) or with setup_sparse.py?

Thanks for all your help,

Costas
