When starting Qt 5 application development in Linux it is necessary to first install Qt 5 development tools. Qt Creator is the IDE used to develop Qt applications. In order for Qt Creator to be able to build Qt applications, library files, header files and a C++ compiler must be installed.

This article shows how to install the necessary packages for Qt 5 application development. It was tested on a Linux Mint 18 Mate 64-bit computer, but should work on other Debian based Linux distributions such as Ubuntu and other Linux Mint versions.
Update November 2019: The installation was tested on Linux Mint 19.2 Cinnamon and MATE.
Install Qt Creator
Qt Creator is an IDE for Qt GUI and C++ code development. It is used to graphically lay out windows and widgets for GUI applications and to edit C++ code.
Install Qt Creator using the following command in a terminal window.
sudo apt-get install qtcreator
Install Qt 5 Libraries, Header Files and Tools
Qt Creator needs Qt 5 libraries, header files and software utility tools to be installed. Without these packages Qt applications would not be able to be compiled. All the necessary packages can be installed by running the following command in a terminal window.
sudo apt-get install qtdeclarative5-dev
Install a C++ Compiler
Finally a C++ compiler must be installed on the system. Qt development is done in C++ in Qt Creator. Applications will not be able to be compiled without a C++ compiler installed. Run the following command to install the g++ C++ compiler
sudo apt-get install g++
With the above packages installed, you are ready to begin developing Qt 5 applications using Qt Creator. You may like to try the Qt 5 Hello World tutorial to start learning how to use Qt Creator to make a simple GUI application.
In Linux mint 18, cinnamon, 64 bit, “no valid kits found” gets displayed for a widgets application. All the above commands were successfully installed. Help please!
@peter, Post a screenshot of Tools>Options>Kits . First, click on “Desktop” though if that option is there on the Kits screen. Take a screenshot of each tab starting with “QT Versions”. I’m getting a “No QML Scene Installed” error myself under the “Qt Versions” and also had to install QMake separately for no apparent reason.
lmao the same
