I first installed manjaro with cinnamon on my PC (intel core2duo, 4GB RAM) and then installed qalculate-gtk. it was working fine.
Then I installed KDE Plasma along with cinnamon and then logged in again in plasma.
But now qalculate does not run. I installed qalculate-qt again and tried to run it. But I still get the error: qalculate-qt: symbol lookup error: qalculate-qt: undefined symbol: _ZN10Calculator33setConciseUncertaintyInputEnabledEb
oh, actually I’m using qalculate-gtk-nognome on KDE - partly because the QT variant wouldn’t let me remove individual history items without doing a context click (GTK can arrow and shift-delete to remove selected items) if I remember.
However, I just installed qalculate-qt and there are no errors, so I’m sorry - no dice.
However, I would say it’s a pretty bad idea to install KDE ‘alongside’ Cinnamon. I tried Cinnamon before I used KDE, and it didn’t play nicely until I sorted out a fresh install.
So, first action, ensure you have a nice rsync backup on another drive containing all your hidden configs in home… and think about a fresh install of KDE and import settings which are useful.
