Embedding Python in C/C++ using Python/C API

[openuser]

Hello,
I've been researching how to embed python into C/C++. And, I learned how to write c/c++ code that, in threory, should do its job in embedding Python module into itself.
Here is what I have..

#include <python2.4/Python.h>
void SomeStuff::someMethod  (void) {
        std::cout << "ErrVisitor" << std::endl;
 
        PyObject *pName, *pModule, *pDict, *pFunc;
 
        Py_Initialize();
        std::cout << "1" << std::endl;
        pName = PyString_FromString ("mailSender");
        std::cout << "2" << std::endl;
        pModule = PyImport_Import (pName);
        std::cout << "3" << std::endl;
        if (PyModule_Check(pModule)) {
                std::cout << "Module" << std::endl;
        } else {
                std::cout << "Not a Module" << std::endl;
                exit(2);
        }
        std::cout << "4" << std::endl;
        pDict = PyModule_GetDict (pModule);
        pFunc = PyDict_GetItemString(pDict, "send_mail");
 
        if (PyCallable_Check(pFunc)) {
                PyObject_CallObject(pFunc, NULL);
        } else {
                std::cout << "Not Callable" << std::endl;
                PyErr_Print ();
        }
Py_DECREF (pModule);
        Py_DECREF (pName);
 
        Py_Finalize();
}

with the following python code: mailSender.py

import smtplib
import os
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email.Utils import COMMASPACE, formatdate
from email import Encoders
 
def send_mail ():
    send_from = "[e-mail]";
    send_to = []
    send_to.append ("[e-mail]")
    subject = "hihihi"
    text = "hihihihihi"
    files = [];
    files.append ('/home/jin/Workspace/scabs/old_split.py');
    server = "smtp.beanfield.com"
 
    assert type(send_to)==list
    assert type(files)==list
 
    msg = MIMEMultipart()
    msg['From'] = send_from
    msg['To'] = COMMASPACE.join(send_to)
    msg['Date'] = formatdate(localtime=True)
    msg['Subject'] = subject
 
    msg.attach( MIMEText(text) )
 
    for file in files:
        part = MIMEBase('application', "octet-stream")
        part.set_payload( open(file,"rb").read() )
        Encoders.encode_base64(part)
        part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(file))
        msg.attach(part)
 
    smtp = smtplib.SMTP(server)
    smtp.sendmail(send_from, send_to, msg.as_string())
    smtp.close()
 

Both Codes are in the same directory, and I use
"g++ SomeCode.h SomeCode.cc -lpython2.4"
to compile my code...

I run with ./a.out,
and the output is the following:

ErrVisitor
1
2
3
Segmentation fault

..
I think the module didnt get imported? How do I make sure that the module DOES get imported? Do I need to do something else at the time of compilation to link these two codes?
Why am I getting a Seg fault?

Any help or insight would be greatly appreciated..

Thank you.
