I've been trying to drive FlightGear from an external instance of JSBSim
running, over a socket. Not having much luck at the moment. Looks like I
have the correct net_fdm header (version 24).
I start FlightGear like this:
$ FlightGear/projects/VC90/Win32/Release/fgfs.exe
--fg-root="c:/cygwin/home/jon/flightgear/fgdata" --aircraft=c172p
--native-fdm=socket,in,60,,5500,tcp --fdm=external
After that is started up I crank up JSBSim with an output specified in the
aircraft config file like this (per the email from HDWysong):
<output name="localhost" type="FLIGHTGEAR" port="5500" rate="60"/>
In the JSBSim console I get this:
Successfully connected to socket for output ...
send: Software caused connection abort
send: Software caused connection abort
send: Software caused connection abort
...
FlightGear immediately core dumps.
Any suggestions?
