[solved] problems with opencv

I am trying to use some of the opencv libraries and seem to be unable to use opencv functions during the program execution. I built and installed opencv 1.1pre1-2 from AUR without any issue using the exact PKGBUILD. This is what happens when I run any example program:

[bgodea@totem python]$ ./houghlines.py photo.jpg
Illegal instruction

I have also compiled some 'c' sample programs using gcc fine, but I get the same message when I run the executable. I've tried a bunch of these files so I know its not the code. It seems that I can import in the libraries okay, but calling the function during execution fails. I've searched around a lot about this problem.

Any ideas? Thanks for any help. I'm using an i686 system.

Re: [solved] problems with opencv

It turn out that the AMD athlon processors do not support SSE/SSE2. This means I needed --disable--SSE2 to be added to the PKGBUILD. I will suggest that this be added.
