Qt for Linux/X11

Qt's support for different Linux platforms is extensive and mature.

To download and install Qt for Linux, follow the instructions on the Getting Started with Qt page.

Supported Configurations

The following configurations are supported.

Distribution	Architecture	Compiler
CentOS Linux 8.1	`x86_64`	GCC 9
openSUSE 15.x	`x86_64`	GCC 9
SUSE Linux Enterprise Server 15 SP2	`x86_64`	GCC 10
Ubuntu 20.04	`x86_64`	GCC as provided by Canonical, GCC 9.x
Generic Linux	`x86` and `x86_64`	GCC 9

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 from Source

You can also build Qt 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.

Deployment and Other Issues

The pages below covers specific issues and recommendations for creating Linux/X11 applications.
