Extension functions stopped being passed around as PyCObjects in numarray-0.3. Instead, I created a new C-type called CFunc which binds an "extension function implementation" to the correct generic wrapper. An added benefit was that CFuncs are directly callable as python functions, whereas PyCObjects were not. The repr of a CFunc looks more like: >>> import _ufuncInt32 >>> _ufuncInt32.functionDict[_ufuncInt32.functionDict.keys()[0]] So, it appears that your c-extensions are not yet updated to CFuncs, but your numarray python code is updated to CFuncs. I suggest deleting your numarray installation and re-installing. Todd > >Greetings, >Jochen > > >------------------------------------------------------------------------ > >? Lib/ChangeLog >?
