=== List of compiled programs ===
The script is able to download and compile:*
FlightGear ( And all the data needed to use it)* cmake ( for newer cmake capabilities)
* [[FlightGear HLA support (High Level Architecture) | OpenRTI]]
Note that OpenRTI is just
another optional dependency for HLA support : http://wiki. flightgear. org/FlightGear_HLA_support_(High_Level_Architecture)
For the time being, you should be just fine building without HLA support. Eventually, the idea is for HLA to replace the existing MP system and even increasingly distribute the FlightGear architecture such that more and more components can be more easily run in separate threads or even separate processes, possibly even on different machines. So this is going to be an important feature for professional users, using several computers and screens to create a comprehensive and immersive simulation environment.
At the moment, it's probably safe to say that HLA is only of interest to developers and people willing to play with experimental features.
can pass the '''-i''' option to compile OpenRTI, as well as SimGear and FlightGear re-configured with -D ENABLE_RTI=ON option (experimental)
