[Numpy-discussion] Unable to get most basic numpy array creation from C++ working.

Hi numpy-discuss
.
I've distilled my problem down to a very simple program that segfaults. I'm
sure I'm doing something silly, but hopefully someone can point me in the
right direction. I create a program called numpy_test.cc:
---------------------
#include <Python.h>
#include "numpy/arrayobject.h"
int main(int argc, char **argv) {
Py_Initialize();
npy_intp length[1];
length[0] = 10;
PyObject* my_array = PyArray_SimpleNew(1, length, NPY_FLOAT);
return 0;
}
---------------------
Standing in the directory above where I've done an in-place build of
numpy-1.3.0, I compile with:
g++ numpy_test.cc -I/usr/include/python2.5
-I/tmp/numpy-1.3.0/numpy/core/include -lpython2.5*
*It compiles clean, but the resulting executable crashes in the
PyArray_SimpleNew line [verified via debugger]. I have yet to get a call to
PyArray_SimpleNew to not segfault.
Any thoughts or advice are appreciated.
Cheers,
rif
