Why not do as it says instead? #define NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION /* Or: NPY_NO_DEPRECATED_API NPY_API_VERSION */ #include <Python.h> #include <numpy/arrayobject.h> Sturla On 17/08/15 13:11, Florian Lindner wrote:

Hello,

I try to converse a piece of C code to the new NumPy API to get rid of the deprecation warning.

#warning "Using deprecated NumPy API, disable it by " "#defining NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION"

As a first step I replaced arrayobject.h by numpy/npy_math.h:

#include <Python.h> #include <numpy/npy_math.h>

But this gives errors that NPY_DOUBLE is not declared.

http://docs.scipy.org/doc/numpy/reference/c-api.dtype.html#c.NPY_DOUBLE gives no information where NPY_DOUBLE is declared, so I used the standard npy_math.h header.

src/action/PythonAction.cpp:90:51: error: 'NPY_DOUBLE' was not declared in this scope PyArray_SimpleNewFromData(1, sourceDim, NPY_DOUBLE, sourceValues);

Including numpy/npy_common.h does not change it either.

Thanks, Florian
