Hi,

after having installed F2PY-2.43.239_1806 I get the following error when
trying to run the hello.f example from the /docs directory:

f2py.py --fcompiler=compaqv -c -m hello hello.f

I'm on Windows XP with Python 2.3.4. Has anybody an idea what's going
wrong? Thanks in advance!

It seems the latest f2py versions need NumPy 23.3 which íntroduces
'weakreflist' in the 'PyArrayObject' struct.

I got the same error with NumPy 23.3.

Try to find your "Numeric/arrayobject.h". Mine has

typedef struct {
PyObject_HEAD
char *data;
int nd;
int *dimensions, *strides;
PyObject *base;
PyArray_Descr *descr;
int flags;
PyObject *weakreflist;
} PyArrayObject;

and is from Numeric 23.3. In one of my installations updating to
Numeric to 23.3 solved a similar error.

Thanks, Bethold for a good hint ...

I had in "Numeric/arrayobject.h"

typedef struct {
PyObject_HEAD
char *data;
int nd;
int *dimensions, *strides;
PyObject *base;
PyArray_Descr *descr;
int flags;
} PyArrayObject;

After adding

PyObject *weakreflist;

I could generate a hello.pyd. Python really is an incredibly versatile
and powerful tool.

Don't do that. You are looking at an old version of
Numeric/arrayobject.h . Delete that directory and everything else
Numeric and re-install Numeric 23.3 . Check it again. It should have the
appropriate members, then.
