Installation on Debian, Ubuntu and derivatives

It's possible to download the deb package from the Download page and install it using:

cd "~/folder with the downloaded file"
sudo dpkg -i "file name.deb"

Installation on Arch Linux and derivatives

In the AUR you can find the latest available version, it can be downloaded and built using yay (or a similar AUR helper) using yay -S gextractwinicons and then following the AUR helper instructions.

The development version is also available in the AUR and can be installed using yay (or a similar AUR helper) with yay -S gextractwinicons-git.

It's possible to download the tar.zst package from the Download page and install it using:

cd "~/folder with the downloaded file"
sudo pacman -U "gextractwinicons-version.tar.zst"

Installation from source code with Python 3

If the prebuilt package will not be available for your distribution you can use the source code package to install gExtractWinIcons using:

cd "~/folder with the downloaded file"
mkdir build
tar xzf "file name.pkg.tar.gz" -C build
cd build/gextractwinicons-*
python3 setup.py build
sudo python3 setup.py install
sudo gtk-update-icon-cache -q /usr/share/icons/hicolor/
sudo xdg-icon-resource forceupdate
sudo xdg-desktop-menu forceupdate
cd ..

After the installation, if no errors were reported the folder build can be removed from root or via sudo rm -rf "build" and the same for the downloaded source package.

After executing the manual installation from source code an automatic software uninstall will not be possibile but you will have to manually delete all the installed files that were reported during the last installation step.
