[gcompris-devel] ubuntu trusty

[aishen]

Seems to compile properly
but doesn't start, following error message

Starting /home/riri/gcompris/GCompris...

Error: Key "<MDSW>" added to modifier map for multiple modifiers; Using 
Mod3, ignoring Mod5

QQmlApplicationEngine failed to load component

qrc:/gcompris/src/core/main.qml:2 module "QtQuick.Controls" is not installed

Error: Your root item has to be a Window.

/home/riri/gcompris/GCompris exited with code 255
what's the problem ?
