Install Qt on Ubuntu

The Qt installers for Linux assume that a C++ compiler, debugger, make, and other development tools are provided by the host operating system. In addition, building graphical Qt applications requires OpenGL libraries and headers installed. Most Linux distributions do not install all of these by default, but setting up a development environment is still straightforward.

Once installed Qt-creator and the Qt-library, open Qt-creator. In Tools/Options/Kits, you can add a compiler (GCC), debugger (GDB), Cmake and Qt-library (and runtime files and OpenGL libraries) (usually in /usr/bin). Then, you can create a Kit there, which contains these elements (compiler for C and C++, debugger, Cmake, Qt-library) and is used for your projects.

• Download Qt installer from the Qt downloads page [web download address].

wget http://download.qt.io/official_releases/qt/5.7/5.7.0/qt-opensource-linux-x64-5.7.0.run

chmod +x qt-opensource-linux-x64-5.7.0.run

sudo apt-get install build-essential

• Install the full runtime files for the generic font configuration library.

sudo apt-get install libfontconfig1

• Configure a compiler (if it’s not automatically detected): Launch Qt creator and go to “Tools > Options > Build & Run > Kit”.
