RexD:

We have a system with a "physics" computer running the simulation at 200 Hz (to simulate servos) and sending a vector of data to a scenery computer. The scenery computer is running Flightgear 2018.1.1 compiled from the "compile" script using Ubuntu 17.10.

Both ends are compiled, but there is a problem with the communications between them. I get the following key messages on the screen:

CHANNEL STRING = SOCKET,IN,120,,5500,UDP
OPTION:NATIVE-FDM = SOCKET,IN,120,,5500,UDP
... (and a bit later)
Splash screen progress binding-subsystems
Entering native_fdm open.
Opened channel communication layer.
Error reading panel:
Failed to open file
(reported by SimGear XML Parser)
CANNOT CONNECT TO SERVER SOCKET ERR = NO SUCH FILE OR DIRECTORY
CANNOT CONNECT TO SERVER REQUEST CHANNEL
jack server is not running or cannot be started
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for 4294967295, skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for 4294967295, skipping unlock

And the two computers do not communicate.

This seems similar to a problem that showed up with multiplayer operation and seems to involve a mismatch with something in simgear.

Does anyone have an idea how to fix it?

Thank you,
Rex du Pont

I am trying to set up a current version of flightgear that I can modify myself.

I have gotten the download _and_compile script and run it.

However, when I try to start I get the following message:

flightgear: Version 2017.4.0
Flightgear: Build type Dev
Built with GNU C++ version 7.2
Jenkins number/ID 0:none
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtimer-root'
Np protocol specified
QxcbConnection: could not connect to display :0
Aborted

I have installed aircraft and scenery in files in a directory that had a soft link via "fgdata" in the ~/.fgfs dirctory
I have made soft link to "fgfs" similarly that goes to the program in the .../flightgear/bin directory.

What do have to do to get it to fly?

Thank you,

RexD: missing directories on startup FG 2017.4.0

I have installed flightgear on a ubuntu 17.10 system, but cannot figure out how to connect up the $FG_ROOT system. i get the following error message when I try to run:

FlightGear: Version 2017.4.0
FlightGear: Build Type Dev
Built with GNU C++ version 7.2
Jenkins number/ID 0:none
QStandardPaths: SDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
No protocol specified
Aborted

My data is in ~/Desktop/AsimTry/install/flightgear/fgdata

I created a link in ~/.fgfs to "fgdata" at the above address.

What should I do to help it find the data files?

Thank you.
