Question

I’m trying to embed a Python script into a C++ application. Before I do such a thing though, I’m trying to run the example script.

Here’s my code:

#include <Python/Python.h>
int main(int argc, char *argv[]) {
Py_Initialize();
PyRun_SimpleString("from time import time,ctime\n"
                   "print 'Today is',ctime(time())\n");
Py_Finalize();
return 0;
}

Compiling with g++ gives me:

Undefined symbols:
  "_Py_Initialize", referenced from:
      _main in cc2Ogphq.o
  "_PyRun_SimpleStringFlags", referenced from:
      _main in cc2Ogphq.o
  "_Py_Finalize", referenced from:
      _main in cc2Ogphq.o
ld: symbol(s) not found

I’m running Mac OSX Snow Leopard and I’m running Python 2.7.2.

You need to link to the python libraries, e.g. libpython.a for static linkage.
