[Qt-interest] ATL in Qt... (Resolved - kinda)

Well, not quite - I resolved it by using namespaces so that my portable versions of the offending classes that were used by the library under Linux/etc could compile and be linked under Windows too instead of using the Windows MFC/ATL counterparts. So a resolution yes, but not the one I was seeking with this thread.

Qt is the Windows version (4.5.2) released by Nokia.

Static library is configured using QMake. Yes I have the

I've tried setting a

Namely: Changing to using static MFC, enabling ATL.
I can try
