Building qt5 on linux

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	Notes
openSUSE 15.1	x86_64	GCC 5 or later, GCC 7, ICC 19.1
SUSE Linux Enterprise Server	x86_64	GCC 5 or later, GCC 10
Red Hat Enterprise Linux 8.4	x86_64	GCC 10.1 via gcc-toolset-10
Red Hat Enterprise Linux 7.6	x86_64	GCC 5.3.1 via devtoolset-4
Ubuntu 20.04	x86_64	GCC 5 or later, GCC 9
Ubuntu 18.04	x86_64	GCC 5 or later, GCC 9
Generic Linux	x86 and x86_64	GCC (5 or later), ICC 18.x

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.

Deployment and Other Issues

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

Where to Go from Here

We invite you to explore the rest of Qt. We prepared overviews which help you decide which APIs to use and our examples demonstrate how to use our API.

• Qt Overviews — list of topics about application development
• Examples and Tutorials — code samples and tutorials
• Qt Reference Pages — a listing of C++ and QML APIs
• Qt X11 Extras — provides additional APIs for X11

Qt’s vibrant and active community site, http://qt.io houses a wiki, a forum, and additional learning guides and presentations.

Additional Information

The top-level qt5 Git repository contains a set of build instructions in the form of provisioning scripts, used by Qt’s continuous integration (CI) system to build and test the supported Reference Configurations. These scripts are useful for anyone building Qt from source, as they provide information on the tools and components that are required for each configuration.
