[vtkusers] [Snapshot-users] How to compile Qt-4.5.x for Mac OS X 10.5.5 to use 64-bits and Cocoa bindings

[Elvis Dowson]

Hi Mike,
		I'm passing an explicit command to build Cocoa as follows:

./configure -platform macx-g++ -prefix /Developer/Applications/ 
Qt-4.5.0  -arch -cocoa -qt-gif

Best regards,

Elvis Dowson
