As far as I know, yes, it still runs under Linux. I develop under Mac 
OSX about 75% of the time, and its library setup is virtually identical 
to Linux. I marked that file as old because I rewrote the Flightgear 
interface some time ago it no longer supports the command line options 
described in that document.

That issue has to do with how Linux and Windows serialize classes when 
they're passed over a network. As I understand it, they pad the object 
slightly differently, resulting in packet sizes that differ between the 
OS's. If you're running an all-Linux network or an all-Windows network 
this shouldn't be problem. I unfortunately don't have enough machines 
to test all of the different permutations.

So, you shouldn't have to do anything special to run under Linux, other 
than build OpenGC.

Here's a good thing to do if you go to a party and you don't know 
anybody: First take out the garbage. Then go around and collect any 
extra garbage that people might have, like a crumpled napkin, and take 
that out too. Pretty soon people will want to meet the busy garbage guy.
