#51466: Zenity works for many commands but not for notification -----------------------------------+---------------------- Reporter: stephane.plaisance@… | Owner: devans@… Type: defect | Status: closed Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: wontfix | Keywords: Port: zenity | -----------------------------------+---------------------- Changes (by devans@…): * status: new => closed * resolution: => wontfix Comment: Currently GNOME notifications are handled via libnotify is designed allow a client to communicate with a compatible notification daemon which actually displays the notification according to the [https://developer.gnome.org/notification-spec/ Desktop Notifications Specification]. Note that the OS X notification system is not directly compatible with this spec and none of the compatible daemons have been ported to MacPorts due to various technical issues. What would be nice would be a daemon that converts client requests to appropriate calls to the OS X system but AFAIK that doesn't exist. Compatible daemons include * notification-daemon * xfce4-notifyd In addition, gnome-shell and KDE KWin provide their own notification daemons. So your error message is saying that zenity can't find a daemon to communicate with. Other GNOME applications that provide notifications are in the same boat. Bottom line is that this is not a problem with zenity itself but the lack of an external daemon that can accept client requests according to the protocol described in the spec. If you'd like to take a stab at porting something to fill the gap take a look at the [https://git.gnome.org/browse/notification-daemon git repo for notify-daemon]. Otherwise there's no current effort (read interest) to address this issue. -- Ticket URL: <https://trac.macports.org/ticket/51466#comment:4> MacPorts <https://www.macports.org/> Ports system for OS X
