Hi: I've been running KDE in Fedora <= 30 and SL <= 7.7 for years. I
just ran $ printenv and found that, in both, QTDIR, QTINC, PATH, QTLIB
are all going through /usr/lib64/qt-3.3
MythTV (from rpms built locally and running from konsole tabs) tells me
it is compiled with and using Qt version 5.12.5 in F30 and 5.9.7 in SL7
I have been having a few OSD-related problems with its development
branch recently and wonder if they might be related to those outdated
environment variables - but just updating them feels reckless.
