The SITL for Windows discussion appears to be dead since Feb of last year.
I will post my query here in the hope it gets noticed.
"I setup sitl on Windows 7. I followed the recipe in the web documentation exactly. Cygwin is working fine. Mavproxy installed without errors. Python installed into the virtual Linux environment ok. jbsim is installed properly. I then built the sitl versions of ArduPlane and ArduCopter sucessfully without errors. Ticks to everything.
When I run Mavproxy from the supplied script I get a graphic with no aircraft icon on it, neither plane nor copter. The graphic does locate at the expected place however, CMAC airfield. I zoomed out to search the world for the aircraft icon but it is nowhere.
If I run the plane Mavproxy crashes complaining about non-existent parameters. Thereafter the console is mostly unresponsive. I cannot exit the console. The Enter key works. The console prompt remains at "initializing". There is no plane icon on the graphic.
If I run the copter Mavproxy does not crash. The console prompt stays at "stabilized". Commands appear to be recognized but the mode does not change and nothing happens. There is no copter icon on the graphic.
The web documentation is also incorrect. It states the command is sim_vehicle.py -j4 --map. There is no sim_vehicle.py. There is a script called sim_vehicle.sh which works. What other errors are in the documentation?
I've wasted a day on this. That's enough. I have research to get on with. Pity, I could have made good use of the simulation capability.
If you have a solution please let me know."
