[Numpy-discussion] embeding numpy in c++

[Sunghwan Choi]

Hi, I am now trying to embedding numpy in my c++ code (more correctly ase
module, which is dependent to numpy). 

My test code is simple 

 

 

test.cpp

#include "Python.h"

#include <stdio.h>

#include <iostream>

extern "C" void Py_Initialize();

extern "C" void PyErr_Print();

using namespace std;

 

int main(int argc, char* argv[])

{

    double answer = 0;

    PyObject *modname, *mod, *mdict, *func, *stringarg, *args, *rslt;

 

    Py_Initialize();

    modname = PyString_FromString("numpy");

    mod = PyImport_Import(modname);

    PyErr_Print();

    cout << mod << endl;

    return 0;

}

 

 

 

 

shchoi@aims0:~/tmp/test2$ vi test.cpp 

shchoi@aims0:~/tmp/test2$ icpc -c test.cpp -I
~/program/epd/include/python2.7/

shchoi@aims0:~/tmp/test2$ icpc -o exe test.o -L ~/program/epd/lib/
-lpython2.7

shchoi@aims0:~/tmp/test2$ ./exe 

Traceback (most recent call last):

    import add_newdocs

    import numpy.core.numeric as _nx

    import multiarray

ImportError:
/home/shchoi/program/epd/lib/python2.7/site-packages/numpy/core/multiarray.s
o: undefined symbol: PyUnicodeUCS2_AsASCIIString

 

 

How to solve this problem? Can anyone help me? 

 

If anyone know the solution, please let me know as soon as possible

 

Sincerely
