State of Qt5 in distributions

[Anna Wilcox]

Hey Nico,

The most important Qt 5 software we still ship is Quassel IRC.  Konversation is available in our repos but Quassel’s core/client model means you get znc-like functionality for “free” without having two layers of clients.

They have talked about an eventual Qt 6 port but I see no activity towards it on their GitHub.  I don’t know the amount of effort it would take to move from Qt 5 to Qt 6 for an app of that size.  This is especially in my mind because of the fact that it was originally a Qt 4 app and I don’t know how many of the shims they are still using.

Our system installer is also currently built against Qt 5 but that is mostly me not having the cycles to update the few places it would need to be updated.  It was written in “clean enough” Qt 5 that it shouldn’t be a problem; just need to find the time.

Thank you so much for reaching out to the distributions list to take a “pulse” of the community.  It really means a lot to me that the KDE project in general continues to foster two-way communication like this.  =)

Best,
-Anna
