Qt and 64 bit Windows 7

[Paolo_R]

Sorry if this is a basic question but I am interested in using Qt but know little about it.

I want to develop 64 bit applications under Windows 7. Is there a Qt option which would allow this i.e. compiling/debugging 64 bit code?

You'll need to rebuild Qt from source: http://en.wikibooks.org/wiki/Opticks_Developer_Guide/Getting_Started/Building_Qt_From_Source

Mmm, that's a pity - not sure my knowledge is up to that!

Are there any tutorials on how to do that using 64 bit GCC/MinGW64?
