Cannot add Multimedia Widgets to Qt Creator C++ project for Raspberry Pi 2

Question

I am trying to compile and run the official Media Player Example in Qt: http://doc.qt.io/qt-5/qtmultimediawidgets-player-example.html for a Raspberry Pi running Raspbian Jessie. I still have no success: when I build the project, the following error appears.

:-1: error: Unknown module(s) in QT: multimedia multimediawidgets.

This is referred to the .pro code:

QT += network \ xml \ multimedia \ multimediawidgets \ widgets

I installed "sudo apt-get install qtmultimedia5-dev" but without success. Is it the right module to install?

My Qt should be up to date, and I don't know where the problem can be. Could anyone help please? Thanks!

The QtMultimedia module now resides in the QtMobility package. So you need to install QtMobility, which provides QtMultimediaKit : I have tested and installed 5 seconds ago to check answer so it works on 12.04 It should be upwardly compatible fingers crossed although even thats a misnomer these days but there you go This is how its done see below sudo apt - get install qtmobility - dev When compiling, you must add the following flags : - I / usr / include / QtMultimediaKit - I / usr / include / QtMobility - lQtMultimediaKit It pays to do a quick search using Google Normally you will find some sensible people who will provide the correct answers (How ever There are very few worth mentioning too these days which is the norm )
