@maiki Have you looked at Pidgin's third party OMEMO plugin by any chance?
Ive been meaning to see if I can get it to build, but I don't know how interoperable it is. And I know youve tried a bunch of the OMEMO solutions out there.
@maiki Ive been kind of scratching my head privately over my own options.
None of the native XMPP clients on Sailfish OS support OMEMO and the gajim package on NetBSD seems to have problems, and as youve mentioned before it seems to have interoperability issues.
Having done a few #pkgsrc packages now, ive been mulling on trying my hand at diving into the #Pkgsrc package on Gajim or focus on packaging one of the many plugins out there but haven't decided which direction yet.
