Re: [Flightgear-devel] Latest CVS Crashes
Just to double check, David made a change to SimGear and to the some of the aircraft config files yesterday. Without the change to simgear, flightgear will crash on startup. If that's not it, then we'll have to take a closer look, although your line numbers don't make sense in your back trace ... Regards, Curt.

Re: [Flightgear-devel] Latest CVS Crashes
Curt, I updated plib, SimGear, and FlightGear before rebuilding. I cleaned everything on Windows because there were some changes to plib headers (MSVC isn't always smart enough to properly handle header changes if they are not in YOUR project). I haven't cleaned the MacOS build because gcc hasn't had such problems. Jonathan Polley On Tuesday, November 12, 2002, at 06:43 AM, Curtis L.

When there's a SimGear change that doesn't touch any headers, FlightGear might not automatically rebuild -- you have to delete the fgfs (or fgfs.exe) binary and then do a make.
