In this article, we will walk you through the process of installing Qt on Ubuntu 22.04. Qt is a popular cross-platform framework for developing applications and user interfaces. It’s widely used for developing GUI applications, and also for developing non-GUI applications such as command-line tools and consoles for servers.
Prerequisites
Before we begin, ensure that you have a functioning Ubuntu 22.04 system. You should also have sudo privileges for performing the installation.
Method 1: Installing Qt using the apt package manager
The apt package manager is a powerful tool that handles installation, upgrade, and removal of software on Ubuntu.
- Update your system
First, make sure your system is up-to-date by running the following command:
This command fetches the list of available updates (sudo apt update && sudo apt upgrade -ysudo apt update) and then installs the updates (sudo apt upgrade -y). - Install Qt Creator and necessary dependencies
Next, install Qt Creator, a cross-platform IDE for Qt applications, and necessary dependencies by running the following command:
Here,sudo apt install -y qtcreator qtbase5-dev qt5-qmake cmakeqtcreatoris the Qt IDE,qtbase5-devis the development files for the Qt5 core library,qt5-qmakeis the Qt5 qmake Makefile generator tool, andcmakeis a cross-platform open-source build system.
Method 2: Installing Qt using the online installer
You can also install Qt using the online installer, which allows you to select the desired Qt version and components to install.
- Download the online installer Visit the Qt website and download the online installer for Linux.
- Make the installer executable
Navigate to the directory where the installer has been downloaded. Make the installer executable by running the following commands:
Here,chmod +x qt-unified-linux-<arch>-<version>-online.run ./qt-unified-linux-<arch>-<version>-online.run<arch>refers to the architecture of your system (either x64 or x86), and<version>refers to the version of the installer. - Follow the installer prompts The installer will guide you through the installation process. You can select the desired Qt version and components to install.
Method 3: Installing specific Qt packages
Starting with Ubuntu 22.04, you can install specific Qt packages using the apt package manager.
- Install specific Qt packages
Run the following command to install specific Qt packages:
If these packages are not found, you can also trysudo apt install -y qt6-base qt6-base-dev qt6-tools-devqt5-base-dev.
