Re: [Paparazzi-devel] FlightGear not working

The correct solution is for us to persuade FlightGear to pack there structure 
consistently in the same way for both 32 and 64 bit versions. 

We sometimes run flightgear on another computer which may be either 32 or 64 
bit.

If they fix the packing at their end then any software that talks to it will 
not have to consider if it is a 32 or 64 bit flightgear.
