Hi @spendist! Your version of libmpdclient is probably too old. This is a newer MPD command to fetch the albumart directly from MPD. If you do not need this feature you can checkout d654d13, then it should compile.

• It may be possible to introduce a configure option for this. But I am not sure if it is worth the hassle.
• Alternatively, version requirements will be added.

See https://github.com/MusicPlayerDaemon/libmpdclient/blob/30dd8d029ccda0dce07e6b57ed7ec8b23bd59a48/NEWS#L23.
