Re: [Flightgear-users] Simgear build breaks; SGAtomic.cxx Curtis Olson Mon Oct 05 11:00:19 2009

The first thing I would try would be a make clean; make of simgear and
flightgear.  Perhaps you did a yum update along the way and got some new
system libraries or a new version of the compiler installed and you have
parts of your build tree built with an older compiler or older system
libraries?

Regards,

Curt.
