Hello Arthur,
I think the two of us should hook-up a little (digitally speaking ofcourse ;) ).
I am using Fedora 9 also on a x86_64 architecture. I am having a little bit of
a rough time compiling pythonOCC, although I did not have to much of a trouble
to compile OCC itself. I am very interested in creating yum
installation packages for
both OCC and PythonOCC, but I would first like to see a clean build.
Regards,
Marco
