Can’t run simulation with FightGear in Mac

[kevinuav]

Hi,everybody. I am tiring to make the simulation of FlighrGear with my mac. Although I do have installed FlightGear(2020.1.2), and I have found the file"fgfs" in the installed package(FLightGear->package contents->MacOS->fgfs) So the “fgfs” is not located in the same directory as in the ubuntu. And I can’t run it at the command line. I can just run it with double clicking the “fgfs” icon…It still encounters errors. Dose PX4 not support FlightGear for mac yet? Or is it just my setting problem? here is the error message: firmware % FG_BINARY="-- /Applications/FlightGear.app/Contents/MacOS/fgfs" make px4_sitl_nolockstep flightgear_rascal [0/5] Performing build step for 'flightgear_bridge’ ninja: no work to do.

FlightGear-bridge is completely untested on mac. We are not using Apple in our development pipeline. Pull-requests are welcomed.

FG_BINARY="-- /Applications/FlightGear.app/Contents/MacOS/fgfs"

Why is there "--" at begin of FG_BINARY parameter? Is it somemething MacOS specific?

Is it still a relevant issue? I want to close it, because the root of the trouble seems to not be related to using Mac. FlightGear simulator code improves significantly in meantime.
