Requirements for Development Host
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.
Use the following commands to install the basic requirements for building Qt applications:
Debian/Ubuntu (apt-get)
sudo apt-get install build-essential libgl1-mesa-dev
Fedora/RHEL/CentOS (yum)
sudo yum groupinstall "C Development Tools and Libraries" sudo yum install mesa-libGL-devel
openSUSE (zypper)
sudo zypper install -t pattern devel_basis
Building Qt 5 from Source
You can also build Qt 5 from the source package and configure it according to your target platform. The source packages are obtained from http://www.qt.io/download/.
Below, you will find more information about building Qt from source.
