Re: [Paparazzi-devel] Re: new script on Wiki

[Felix Ruess]

Hi,

ok, I corrected the ln command on the wiki to link the directory
 sudo ln -s $PAPARAZZI_SRC/conf/simulator/flightgear/
/usr/share/games/FlightGear/Models/Aircraft/paparazzi

Notice there is no * after the paparazzi flightgear directory. This
did not work since the shell expanded to all files in that dir.

Cheers, Felix
