Qt 5.5: module "QtAudioEngine" is not installed - qt

I'm running the official Qt 5.5 SDK on Ubuntu 15.10 and trying to play 3D sounds in QML:
import QtAudioEngine 1.0
The project file:
qt += multimedia
The import statement results in qrc:///Main.qml:1:1: module "QtAudioEngine" is not installed. I'm a bit confused as I can see that the needed libs are in the SDK. What might be wrong here?

It's a bug in the official Qt SDK : https://bugreports.qt.io/browse/QTBUG-51567

Error loading apt-installed QtDataVisualization at runtime on ubuntu

I'm running Qt 5.12 on ubuntu 20.04.3. Qt software components are installed with apt. My C++ application uses Qt DataVisualization . I've installed these apt packages for DataVisualization:
libqt5datavisualization5-dev
qml-module-qtdatavisualization
The app compiles OK, but the runtime cannot find the qml module. My qml file contains this import statement as specified by Qt documentation:
import QtDataVisualization 1.15
But at runtime I get the error:
QQmlApplicationEngine failed to load component
qrc:/main.qml:6 module "QtDataVisualization" version 1.15 is not installed
I get a similar runtime error if qml has "import QtDataVisualization 1.14".
Can someone help please? Thanks!
This page indicates that DataVisualization 1.2 should be imported for Qt 5.12 applications - this resolves my issue.

I have this version of Qt. still unable to use Qt.controls and QtQuick 2.0.

I have updated my Qt version to
Qt Creator 2.7.1
Based on Qt 5.0.2 (32 bit)
Built on Sep 6 2013 at 08:23:22
Still I am not able to use Qt Quick controls and Qt Quick 2.0. I get this error
module "QtQuick" version 2.0 is not installed
import QtQuick 2.0
I have imported QtQuick 2.0 still it's not working.
The solution might be adding:
QT += quick
in your .pro file. If it doesn't help please install this.

Qml - error : module "QtMobility.location" is not installed

I installed Qt SDK 1.2.1. when I write a program using QtQuick and I want to use of QtMobility.location 1.2 the following error will occur :
module "QtMobility.location" is not installed
Can anyone help me ? When I install Qt sdk , is Qt mobility installed automatically ?
Be sure to declare the following in the pro file:
symbian:TARGET.CAPABILITY += Location
MOBILITY +=location
As far as i remember - Qt mobility can be checked to be installed or not, check Qt SDK update manager.

Building Qt 4.8 with mingw fails - "I couldn't find a pro file for QtCore module"

I'm trying to re-build Qt 4.8.0 in Windows statically. I'm following the documentation here: http://doc.qt.nokia.com/4.8-snapshot/deployment-windows.html. After typing config -static in a mingw terminal at C:\QtSDK\Desktop\Qt\4.8.0\mingw, I get the following error:
Running syncqt...
I couldn't find a pro file for QtCore module
syncqt failed, return code 2
I've been looking all over and can't figure out where to go from here! IMO the Qt documentation is not very good in this regard.
Thanks!

Problem with QtWebKit 4.7.2 on Symbian^3 device

I'm currently writing a QML application using the Qt SDK 1.1 beta and I'm making use of QtWebKit. The application works fine on Windows and within the simulator, but when I try to run it on a Symbian^3 device (N8), I get the following error:
[Qt Message] file:///C:/Private/ef18eef4/qml/qml/inlinehtml.qml:42:1: plugin cannot be loaded for module "QtWebKit": The file 'C:/resource/qt/imports/QtWebKit/qmlwebkitplugin.qtplugin' is not a valid Qt plugin.
import QtWebKit 1.0
^
This is also the case with any of the QtWebKit examples that I try to run. I installed qt.sis and qtwebkit.sis found in QtSDK\Symbian\sis\Symbian^3\Qt\4.7.2 to the device.
Any ideas on what could be causing this problem? Thanks.
Have you tried:
import Qt 4.7
import org.webkit 1.0
?
