Re: [Pysparse-users] Requesting help with PySparse installation

[Daniel W. <dan...@gm...>]

I am not sure what the issue is, but it might be better to build pysparse
against a version of python and numpy that is distributed and installed by
the package manager for your system. Is there a numpy rpm available?

If for some reason that doesn't work or isn't available, maybe try
installing numpy by hand using the system python. You can try different
options in a virtualenv if you use that rather than installing into your
system directories. Certainly with enthought, it is better to install in a
virtualenv rather than messing with the system directories while
prototyping.

Googling the actual issue, this may be a 32 versus 64 bit issue.

Maybe using a 32 bit distribution on a 64 bit platform is not the way to go
(speculation). Is there not a 64 bit dist? Like it says in the link maybe
try passing some of the 32 bit flags to gcc.

Hope this helps in some way.
