[SciPy-user] Problem with Weave

[Bob.Cowdery at CGI-Europe.com]

I am about to convert some python code to 'C' so am going through the Weave
documentation. I can get most things to work except returning values from
the 'C' code. I would guess the correct libraries are not getting into the
compile but I don't know how to fix it. I can compile and run any 'C' code
fine until I use any of the Py:: classes.
 
As an example if I type:
 
>>> import weave 
>>> a=1
>>> a=weave.inline("return_val = Py::new_reference_to(Py::Int(a+1));",['a'],
verbose=2)
 
this gives me:

Any help appreciated.
