Calling python eval from C ++

I am basically trying to do the same as the next question, but I get runtime errors when called PyObject_Print

, complaining about an error in "toupper () at 0x776e0226"

Python C API: Using PyEval_EvalCode

My code:

int callExecFunction(const char* evalStr)
{
    PyCodeObject* code = (PyCodeObject*)Py_CompileString(evalStr, "pyscript", Py_eval_input);
    PyObject* global_dict = PyModule_GetDict(pModule);
    PyObject* local_dict = PyDict_New();
    PyObject* obj = PyEval_EvalCode(code, global_dict, local_dict);

    PyObject* result = PyObject_Str(obj);
    PyObject_Print(result, stdout, 0);
}

      

        
        
        
      

    

evalStr "setCurrentFileDir()"

and pModule was initialized earlier from script without error and worked like this code: http://docs.python.org/2/extending/embedding.html#pure-embedding .

And inside the loaded module there is a function:

def setCurrentFileDir():
    print "setCurrentFileDir"
    return "5"

      

        
        
        
      

    

What I missed / did wrong in the call to the eval function. Please note that I cannot call the setCurrentFileDir function "directly" through the python API, I have to use eval.
