I need this libqdialogsolver, for Tumbleweed advice…and the springs are fine too.
Thank you so much

I found this:

Not really recent and not a solution, but you could try to follow Next and the Bugzilla …

Maybe it has useful info.

Nobody ever ported libqdialogsolver to Qt5. The code still uses Qt3 support which has been removed in Qt5, i.e. it never even has been ported to Qt4 properly.

IOW, there is no (working) libqdialogsolver currently.

Thank you so much;)
