Summary: using python extension(wxPython) in c 

Initial Comment:
hello,all.
     i am confronting with a weird problem, almost forcing to die,the feeling is miserable, so pls help me.
here is a python application named "helloWorld",a simple gui application, assisted with wxPython.
from wxPython.wx import *
class myApp(wxApp):
      def OnInit(self):
            frame = wxFrame(NULL,-1,"hello,world!");
            frame.Show(true)
            self.SetTopWindow(frame)
            return true
app = myApp()
app.MainLoop()

also sorry for my unsmart code, which i should import wx not wxPython.wx.

and i want to use the simplest way to combine with c.so i use:
#include "python.h"
#include "wx/wxPython/wxPython.h"
#include <iostream>
using namespace std;

int main()
{
  Py_Initialize();
  if(!Py_IsInitialized())
  {
    cerr << "hello,world!"<< endl;
    return -1;
  }
  PyRun_SimpleString("from wxPython.wx import *");
  PyRun_SimpleString("class myApp(wxApp):");
  PyRun_SimpleString("     def OnInit(self):");
  PyRun_SimpleString("          frame = wxFrame(NULL,-1,"hello,world!")");
  PyRun_SimpleString("          frame.Show(true)");
  PyRun_SimpleString("          self.SetTopWindow(frame)");
  PyRun_SimpleString("          return true");
  PyRun_SimpleString("app = myApp()");
  PyRun_SimpleString("app.MainLoop()");
  Py_Finalize();
  return 0;
}
in addition, to make this work, i have configure something like this:
add the wxpython include/library files in vc.
includes:
c:\wxPython-src-2.6.3.3\wxPython\include.
c:\python24\include\wx(it is the product of building wxPython)
also the python include here.
c:\python24\include
libraries:
c:\wxPython-src-2.6.3.3\lib\vc_dll(the build product of wxWidgets)
c:\wxPython-src-2.6.3.3\wxPython\wxPython
c:\python24\libs
to supplement the problem, i install wxPython from source code,and i have gotten three files,all of which will be uploaded here.

and both them can pass the build process,but get "detected memory leaks  and dump objects"in the run process.
i figure that it has great memory leaks when loading certain symbols,like wxmsw26ud.lib or such,while other lib are not loaded "no symbol loaded!"

but i donot know why, and donot know how to build a wxPython script within c.
here is the error message:
Detected memory leaks!

thanks one billion times if someone can tell me,coz the progress should be advanced further.and all my other people awaits it.

Please don't use the bug tracker as a means to get support; it is not
meant to be used that way.
Instead, try to get help e.g. on news:comp.lang.python

I can see various errors in your code; as a starting point, check the
result of PyRun_SimpleString.

Closing the report as invalid.
