[SciPy-dev] status of newcore and f2py

[Pearu Peterson]

Hi,

When forcing f2py to use newcore, that is, when changing

#include "Numeric/arrayobject.h"

to

#include "scipy/arrayobject.h"

in newcore/scipy/f2py2e/src/fortranobject.h, then I get the folloing 
messages

when compiling fortranobject.c and when trying to import the corresponding 
extension module, I get

>>> import foo
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
ImportError: ./foo.so: undefined symbol: _PyArray_multiply_list

So, we need to have a newcore replacement for _PyArray_multiply_list. Is 
there anything available already?
