Failed to import a "pyd: File When python intepreter embed in C++ project

[liujz39 at gmail.com]

I create a pyd File named "testPyd" with boostPython,and then I import the testPyd module into "test.py", it works perfect!
But when I embeded the python interpreter into my C++ project and run the "test.py", it comes out a "ImportErr: no module named testPyd".
It has confused me for two days and I googled for long time,but I can't find the answer!
Anybody here can help me ?
Thank you!
