Currently writing a C extension for Python, I successfully compiled and use the numpy C-API within the main/loader file of the module extension.
I am now trying to move the logic into a different C file. Following the documented procedure, I set up the following declarations.
Inside the module loader file:
#define NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION
#define PY_ARRAY_UNIQUE_SYMBOL CCMAP_ARRAY_API
#include "numpy/arrayobject.h"
Inside the file carrying the interactions with the numpy API
#define NO_IMPORT_ARRAY
#define NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION
#define PY_ARRAY_UNIQUE_SYMBOL CCMAP_ARRAY_API
#include <Python.h>
#include "numpy/arrayobject.h"
The compilation breaks on the file carrying the interactions w/ the numpy API

Under MacOS 11.6, I am missing a point here. Should I change/adapt my toolchain for such a seemingly minor change in file organization ?
