I have create an OpenSceneGraph34 package and submitted it to games: https://build.opensuse.org/request/show/619958 Next, I took your SimGear and FlightGear branches, fiddled a bit with SimGear, and now both packages build again: https://build.opensuse.org/package/show/home:StefanBruens:branches:games/SimGear If it is ok for you, I will submit both packages to games after OpenSceneGraph34 has been accepted.
