Qt on host ?

Hi,

I coded a Qt application on my host computer with a recent version of Qt,
and now I would like to compile it with the cross-compiler to make it works
on my FriendlyArm mini2440.

I think I have to build a version of the Qt used in my FriendlyArm (4.6.3)
but for my host computer, so that I will be able to cross-compile a Qt
application using Qt 4.6.3 from my host for my friendlyArm.

I would like to know if I am right ? Do I have really to build my
application with the same version of Qt of the friendlyArm ? 

Thanks
