Installing Qt 5.x on Ubuntu globally

Question

Hello everyone! :)

I need to install Qt 5 globally on Ubuntu to be able to use QML libraries like Kirigami. However, the wast majority of Google search results tell how to install it locally (as a folder) from Qt's official website. How can I install Qt 5.x as a set of packages to get something functionally equivalent to Qt installation from qt.io?
I use Ubuntu 16.04.1 on my x64 PC.

Thanks in advance!

Solution

That will probably cover it:

sudo apt-get install qtdeclarative5-dev qml-module-qtquick-controls

I have previously installed some other Qt packages, so both ones you've mentions are already installed. However, when I try to launch a sample app ("Stickman"), it says "/home/ilya/stickman/graphicsview.h:44: error: QtWidgets/QGraphicsView: No such file or directory". Also, Qt from qt.io comes with lots of QML samples.

QGraphicsView is in QtWidgets, so it's not useful when working with QtQuick.

Oh, thanks :) I'll try working with QML and write back.

Compiling a sample QML-Material application produces the following error message: /home/ilya/demo/main.cpp:1: error: QGuiApplication: No such file or directory

It should be in /usr/include/x86_64-linux-gnu/qt5/QtGui/QGuiApplication. It's in qtbase5-dev package which is installed by qtdeclarative5-dev.

The problem is that on compilation Qt uses headers for Qt 4, although Qt 5 is selected as default both in Qt Creator and systemwide. Now trying to solve.

The problem was in "Desktop" configuration. Now solved and things seem to work poperly. Thanks so much for help :)
