I've been trying to get the Numeric-19.0.0 working on Python 2.1b2 under OS X.

If anyone can get it to work, some impressions of the performance available on a G4-based Mac would be welcome. They are reputedly a lot faster than a Pentium 4 and are much cheaper than an Alpha box, at least they are here in Australia.

Which begs the question: are there any Numpy benchmarks available to compare Numpy on different platforms, or to compare Numpy with its alternatives on the same platform (Numpy would have to be proven a lot slower for me to change!).

dyld: python multiple definitions of symbol _PyArray_API /usr/local/lib/python2.1/site-packages/Numeric/multiarray.so definition of _PyArray_API /usr/local/lib/python2.1/site-packages/Numeric/umath.so definition of _PyArray_API

At this point, I get returned to the command line (python exits). It appears that the dynamic linker mechanism under OS X doesn't like symbols with the same name. Anyone have a way around this ?

You'd have to declare PyArray_API static in each module, but that won't be easy as some modules consist of more than one C source file.

A more complicated solution would be to construct different names for this variable in different modules using preprocessor tricks in Numeric/arrayobject.h.
