Is there a Maintenance Tool that is downloadable everywhere-open-source, even source, for Qt 5.5.1? It works just fine in the Debian Jessie for AMD64 desktop from the Debian packages, but trying to get it (AND QT ITSELF!!!!) to install and run on a Raspberry Pi 2 does not even load source or executable for MaintenanceTool. What gives?

So FREAKIN' many problems getting Qt 5.5.1 and QtCreator to work on an RPi2, it's driving me mad. A very old version of QtCreator works sorta, but it does not have the functionality that the new Creator does. If one loads the package from Debian, you get 5.3.2 and a QtCreator that works with that, sorta, kinda, maybe, a little bit.

I need to learn Qt for the desktop as well as embedded.
