Installation on Exherbo

Amarok 2 is available in the Exherbo KDE repository. If the KDE repository is not already installed you can install it with the following command:

# cave resolve repository/kde -x

To see what versions of Amarok is available for installation do:

# cave show amarok

The show command will also print the available package options for Amarok along with a description of what the options enable/disables. If you want to change the package options you need to specify this in the file /etc/paludis/options.conf as described here, using the specification format as described here.

Some versions of Amarok might be repository-masked ("R"), meaning it is considered unstable. To install such a version anyway, you will need to unmask it in the file /etc/paludis/package_unmask.conf as described in the Exherbo package manager documentation here also using the package specification format.

To install amarok, use the following command:

# cave resolve amarok -x

On Exherbo there's also an SCM(Source Control Management) version of Amarok, i. e. one that installs the latest Amarok from the live Git repository.
