I am writing my own FDM, is there an API that I can use so I can use 
Flight Gear as my front end?
Yes, take a look at net_fdm.* and native_ctrls.* in the 
FlightGear/src/Network directory. Those are the one you want to use.

[Flightgear-devel] Re: [Simgear-cvslogs]

2004-12-02 Thread Martin Spott

Hello Curt,
could you please revert this change and remove the whole FreeBSD
clause - it just makes life harder on the cuurrent FreeBSD RELEASE - or
change it. See below.

Thanks alot,

Hi Martin,
Ok, this sounds reasonable.  I assume this means that the isnan() 
problems are fixed in newer versions of FreeBSD?

Thanks,
Curt.

To be honest: I don't know if the current handling in FreeBSD-5.3 is
_correct_, I just can state that the clause you introduced at this
place annoyed the compiler  :-)

I got this error:

C++ linkage

*** Error code 1


BTW: The workaround wasn't my own idea, I borrowed it from the folks
who patched PLIB for the FreeBSD port  ;-)

Thanks,
Martin.

Perhaps this is why it is OK with OSX?

[Flightgear-devel] New scenery build

2004-12-02 Thread Curtis L. Olson

I am currently working on building the latest round of world scenery for 
FlightGear.  I'm not done, so don't consider this to be the official 
announcement.  However, for those that want to get a jump on the 
competition, you can find the new scenery here:

   ftp://ftp.flightgear.org/pub/fgfs/Scenery-0.9.7/
This scenery should work just fine with the 0.9.6 version, but some 
radio towers will look better running with the current CVS version of FG 
... not a big deal.

There is nothing ground breaking in this new build.  It is mostly a 
collection of small fixes, and is based on the latest[1] airport data 
from Robin Peel including many submissions from FG developers and 
users.  I've done quite a bit of addition work on airport surfaces so 
the little odd cliffs that showed up in a few places mid-runway should 
now be gone.

[1] Well, the latest data as of the start of my build ... figures he 
would release an update before I was finished, but I'm past the point of 
no return now.

Regards,
Curt.
