The mono-addins port has been deprecated upstream (and has not been maintained for over a year.) The devel/mono-addins port will be deprecated as part of Mono cleanup efforts to bring in 6.8+. Please confirm if the port actually needs anything from devel/mono-addins. If we can just remove the dependency, that would be best. If a component from addins is still needed, we should figure out where that piece is and if it is actively maintained or an alternative way to bring it in.
Hello, Thanks for your report. mono-addins seems to be used everywhere in Pinta: https://github.com/PintaProject/Pinta/search?l=C%23&q=mono.addins&type= So, what should be done? Who said mono-addins is deprecated? The last commits were in November 2019: https://github.com/mono/mono-addins/commits/master PS: I am not familiar with Mono or its libraries. Best Regards, Olivier
Well, I've just tried to remove the mono-addins dependency and rebuild Pinta. And, of course, it doesn't work :-( Do the mono-addins upstream provides something else to migrate to? Maybe I could patch Pinta's source to remove the mono-addins dependency? It seems to be used to add plugins, so it may not be needed for the main functionality.

(In reply to OlivierW from comment #2) I have been working pretty closely with the Mono team; the actual last commits to the mono-addins repository was actually 2018. The actual last release was 1.3.3 in 2017, and the link referenced in the port directs an 'archived' page since 2018. A lot of this stems from Mono migrating to the dotnet/runtime repository. Given that, I checked with the Mono team, and they stated that nobody has been actively maintaining mono-addins for quite some time. The first set of errors can be solved simply by not relying on Addins. (Well, that's easy enough, right?) The problem is, TypeExtension* are actually part of a mono-addins. And unfortunately it looks like Pinta actually hasn't been updated since 2015 itself. It may unfortunately be time to let this one die. :(
Well, you're right, it's probably better to let Pinta die :-(
Well, I have a good news: I have been told mono-addins is not deprecated. I hope we will keep it together with Pinta :-) Best Regards, Olivier
Pinta is receiving commits: https://github.com/PintaProject/Pinta/commits Latest: Nov 19, 2019. mono-addins is receiving commits @ GitHub (Latest Nov 22, 2019): https://github.com/mono/mono-addins/commits Conversation [1] with Marius Ungureanu (therzok, committer and Senior Software Engineer @microsoft) on Twitter: "Hey, mono-addins is not deprecated, it's still largely used in MonoDevelop. There's no active feature development on it right now, but that's a different story" Marius also mentioned using VS MEF as a potential alternative, but this should be coordinated upstream (@Pinta) if appropriate and suitable [1] https://twitter.com/Therzok/status/1219439705042956288
