Installing GTK on Linux Distributions

This section describes how to install GTK on Linux distributions.

There are two ways to install GTK:

  • Install from distribution packages.
  • Build from source.

Installation from Distribution Packages

This is the easiest way to install. The following command installs the GTK (version 4) development files on Ubuntu.

$ sudo apt install libgtk-4-dev

It is important to install the development package (libgtk-4-dev). Otherwise, you will not be able to compile any GTK-based programs.

Fedora, Debian, Arch, Gentoo, and OpenSUSE also have GTK packages. See the website of your distribution for further information.

Package information for Arch, Debian/Ubuntu, and Fedora is described on the GTK website: Installing GTK from packages.

Installation from Source

If you want to install the development version of GTK, you need to build it from source. See the Compiling the GTK Libraries section of the GTK API reference.

  • Click on the green <> Code button. A dropdown menu will appear; click Download ZIP.
  • The repository will be downloaded as a zip file to your computer.
  • Unzip the file.

Clone the Repository

  • Click on the green <> Code button. A dropdown menu will appear. The first section is Clone with three tabs. Click the HTTPS tab and click the copy icon to the right of https://github.com/ToshioCP/Gtk4-tutorial.git.
  • Open a terminal and type git clone, then press Ctrl+Shift+V. The command line will look like git clone https://github.com/ToshioCP/Gtk4-tutorial.git. Press Enter.
  • The directory Gtk4-tutorial will be created. This directory is a local copy of the repository.

Examples in the Tutorial

Examples are under the src directory. For example, the first example of the tutorial is pr1.c and its path is /src/misc/pr1.c. Therefore, you do not need to type the examples manually.
