First of all, 2.9.x are OSG developer releases (unstable). The stable OSG release was 2.8.3 for a long time - now there's 2.8.4 (since April). I'm not aware of major issues concerning stable OSG.
We're checking "compile-compatibility" against OSG trunk regularly (automatic Hudson build). When necessary, we're adapting to OSG changes - though that will take a few weeks. Sometimes bugs are also introduced on the OSG-side - like http://code.google.com/p/flightgear-bugs/issues/detail?id=268 Incidentally, I have just invested a lot of time this weekend, tracing the specific OSG commit causing the problem and debugging it. The problem is now identified (OSG forgot to update one of their font plugins) and thankfully the OSG maintainer is now looking into this. There's also a temporary patch in our tracker. If the black sky issue persists for some time (i.e. OSG isn't fixing the issue themselves - which they often do, since most bugs aren't FlightGear-specific and there are a lot of active OSG devs/testers), then someone of us will also need to look into this. So, we're not "stuck in a time warp" just because there are occasional OSG issues. But it's tiring to be a constant OSG beta-tester. Seems we have enough own issues to take care of. Anyone volunteering though is welcome to test OSG trunk regularly, check for new issues, trace conflicting changes and report problems - preferably on a level which can be reported to OSG directly. Indeed, I guess Tim would be happy for any help in maintaining the FG/OSG code. And remember: you're not getting any new features just by installing a fancy new OSG library. We'd also need someone to add new code to FG in order to take advantage of available OSG features. cheers, Thorsten ------------------------------------------------------------------------------ Achieve unprecedented app performance and reliability What every C/C++ and Fortran developer should know.
