Migration to QT 5

[pl01]

Hi,

I'm trying to migrate my soft from QT 4.7 to QT 5.0.2.

I have build QT for Windows 64 with MSVC 2010 and everything looks correct, but.... when I compile my soft I got a lot of "link" errors.
Does someone have an idea ?

Error 41 error LNK2001: unresolved external symbol "__declspec(dllimport) protected: static struct QVariant::Handler const * const QVariant::handler" (__imp_?handler@QVariant@@1PEBUHandler@1@EB) c:\MyApp\QSceneNavigator.obj MyApp

Have you started from a completely clean slate?
Did you add "widgets" to QT in your pro file?
Have you rerun qmake?
