[Qt-interest] ATL in Qt...

[Scott Aron Bloom]

You will need to build Qt using the same compiler....

The version provided by Nokia is built with mingw...

Qt is the Windows version (4.5.2) released by Nokia.
The rest are all compiled under the same compiler - MSVS 2008 SP1+TR1

Static library is configured using QMake. Yes I have the source; it is built as part of the project.
While it is just standard C/C++ its project file is a QMake project.
All the projects are converted to VC++ using:

qmake -tp vc <qmake project>

One set of projects is converted using:

qmake -tp vc -r <general qmake project>

I've tried setting a number of compiler options on the main project/solution but to no avail.
Namely: Changing to using static MFC, enabling ATL.

I can try the dynamic MFC/ATL too.

I really only need to link some stuff in. Is there a trick to
