Don't use the unsupported frameworks branch :) Anyway a bug is being discussed at https://git.reviewboard.kde.org/r/125890/ I'll close this since frameworks is unsupported as i said.
Eerm... does "unsupported frameworks branch" means "KF5-based version"? If so, does it mean, that it is only KDE4-based versions are supported? And, by the way: doesn't that fix from reviewboard applied to the GIT HEAD yet? Because it marked as created 31 Oct, while I built okular about 3 Nov 01:00 UTC :-/ // And, also btw: what means "unsupported" in this case? :) I just installed it fom git HEAD because there is no another KF5-based version of okular (to be able to drop kde4 pieces) Also, I thought, that by installing "bleeding edge" versiona I kinda "working" like tester, reporting any problem I found in bleeding edge code before users will found them in released versions. So terminology "unsupported" in that case is a bit unclear for my understanding :)
> Eerm... does "unsupported frameworks branch" means "KF5-based version"? in this case yes. >If so, does it mean, that it is only KDE4-based versions are supported? Correct, Okular only supports kdelibs4-based versions at this stage. > And, by the way: doesn't that fix from reviewboard applied to the GIT HEAD yet? No since git head is based in kdelibs4 anyway >I just installed it fom git HEAD because there is no another KF5-based version of okular (to be able to drop kde4 pieces) Again git HEAD (aka master) is kdelibs4-version, so don't think you did that, you install the unsupported frameworks branch >Also, I thought, that by installing "bleeding edge" versiona I kinda "working" like tester, reporting any problem I found in bleeding edge code before users will found them in released versions. Yes, we encourage people to install the development version and report bugs, the development version is the master branch
uhm... ok. Actually, I really don't looked which exactly branch I installed, sorry ;) I just installed scm version of package from kf5 distro repo, and didn't assumed it can be non-master branch. Shame on me, sorry :)
