I really only have one app - Xiphos. It's just been compiled under two different toolkits. They are supposed to be feature-identical and complete, which they both are to my knowledge. It's just that one of them (GTK2) gets routine updates and fixes whereas the other (GTK3) does not receive the same level of concentration from upstream. I really only want the GTK2 to be exposed to casual users - which is what I suspect is the majority of users of the gnome-software interface.

I would suggest to just ship one of them. There are users who have specifically requested the GTK3 version be made available, since they try to keep the GTK2 stack off their systems for a variety of reasons. Since upstream provides both, though with differing levels of support, upstream and users both ended up asking for different builds to be available. Upstream is primarily interested in GTK2 and simply defaults to telling users to install that version when a bug is first found in the GTK3 version. Some users, though, only wanted the GTK3 version. I'd like to keep it to only one instance of Xiphos appearing in the gnome-software interface that will cover the majority of users who are just looking for the application. They would get the GTK2 build, preferably. Anyone wanting the GTK3 build should be able to get it from the command line, directly. --Greg -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://lists.fedoraproject.org/admin/lists/devel@xxxxxxxxxxxxxxxxxxxxxxx
