Linking debug C++ DLL with python dlls

[Mathieu Gontier]

Hello,

I often build Python on Windows.

What I can say is it not so trivial to build debug libraries for Python: 
each debug library must have the postfix *_d.dll/.pyd.

Another useful information. On Windows, a shared library is linked to 
our application though a associated file with the .lib extension. This 
"static library" contains all the information relating to de 
__declspec(import) / __declspec(export) instructions you should add in 
the code. The most important in Python is that the shared libraries 
(usually with the extension .dll) have as extension .pyd.
So, you can change it in Visual Studio.
