[Pythonmac-SIG] Mac PyImport_ImportModule("modulename")

[Zhi Peng]

Hi! Bob 

Following is the main code that I used for test. The
sys.path seems correct because I can import when I use
pythonw and import SringModule. Everytime I run the
program, it said "can not import 
StringModule". One might use a simple module with only
one sentance inside as a "StringModule.py" and
"StringModule.pyc".

Thanks 

Zhi 

======================================================


#include <Python.h>


int main()
{
        PyObject
*myMod=NULL,*myClass=NULL,*myModuleInstance=NULL;

       
        Py_Initialize();

        PyRun_SimpleString("import sys \n");

        PyRun_SimpleString("sys.path.append('.\')\n");
        PyRun_SimpleString("print sys.path \n");

        //myMod=PyImport_ImportModule("os");

        myMod=PyImport_ImportModule("StringModule");
        if(!myMod) { printf("cannot import
StringModule\n"); return TRUE; }
        return 0;

}



The 'StringModule' is in the right directory as
following: 
==================================================
zhi-pengs-power-mac-g5:/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3

zpeng$ find . -name 'StringModule.py' -print 
./StringModule.py

zhi-pengs-power-mac-g5:/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3


zpeng$ find . -name 'StringModule.pyc' -print 
./StringModule.pyc
