Hi,
I tried to embedding numpy in C++ but I got
ImportError: numpy.core.multiarray failed to import
Do you know any ways to solve this problem?
I copy my codes and error message
Makefile
CXX= icpc
all: exe
clean:
rm -rf *.o exe
exe: test.o
$(CXX) -o exe test.o -L/home/shchoi/program/epd/lib/ -lpython2.7
test.o : test.cpp
$(CXX) -c test.cpp
-I/home/shchoi/program/epd/lib/python2.7/site-packages/numpy/core/include/nu
mpy/ -I/home/shchoi/program/epd/include/python2.7
tmp.cpp
#include "Python.h"
#include "arrayobject.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();
import_array();
modname = PyString_FromString("numpy");
mod = PyImport_Import(modname);
PyErr_Print();
cout << mod << endl;
Py_Finalize();
return 0;
}
$ make
icpc -c test.cpp
-I/home/shchoi/program/epd/lib/python2.7/site-packages/numpy/core/include/nu
mpy/ -I/home/shchoi/program/epd/include/python2.7
test.cpp(15): warning #117: non-void function "main" should return a value

$ ./exe
