It should work just as on Windows. If you look through the implementation in PThread.c++ you'll notice that there are a few instances where -1 is returned; it would help to find out what exactly is happening: - did cmake fail to find a usable sched_setaffinity() or - did the actual call fail Cheers, /ulrich _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
