Hi,

I am getting the following error when trying to launch marble-qt:

marble-qt: symbol lookup error: marble-qt: undefined symbol: _ZN6Marble18MarbleInputHandler27setMouseViewRotationEnabledEb

My guess is that it comes from the outdated marble-common in libre.

# pacman -Ss marble
libre/marble-common 18.12.2-1.parabola1 [installed]
    Common libraries and plugins for Marble
extra/marble 20.04.1-1 (kde-applications kdeedu)
    Desktop Globe
extra/marble-qt 20.04.1-1 [installed]
    Desktop Globe (Qt version)

marble-common was introduced into libre by oaken-source as part of issue #2117.
