[SOLVEDish] Flightgear: can't figure out how to add aircraft

[statikregimen]

Good day,

Seems no matter what I try, drawing from the Gentoo wiki and other sources, Flightgear will not find and/or load any downloaded aircraft. Flightgear was installed from the official Gentoo repository. I've lost the plot after a few nights of trying, so here are some initial data points (despite me trying many many other things, and presuming I'm now way off course):

What concerns me about some of the above command outputs, is that a couple of times it says

Code: Select all

init package root at:Path "/home/statik/.fgfs/Aircraft"

So it seems to be looking in the right place. Again, I've simply tried too many things to give much more of a detailed summary of ground I've already covered at this point (basically starting over, hopefully with some help), but assuming I'm missing something obvious.

Thanks for reading.

statikregimen, if you compiled flightgear with the qt5 flag, you can start it with

Code: Select all

fgfs --launcher

This gives you a GUI launcher, where you can configure various settings and also set the aircraft search path or download additional aircraft.

Without it, maybe you can use some of the options shown by

Code: Select all

fgfs --help

[AJM]

My ~/.fgfs/fgfsrc contains this line (amongst many others):

Code: Select all

--fg-aircraft=/usr/local/share/fgfs/flightgear-fgaddon/Aircraft:/home/aj/.fgfs/Aircraft/aj

Edit... another thing to watch for is case - the current / SVN version of the Sikorsky 51 at least is launched with

Code: Select all

--aircraft=S-51

, NOT s51 etc. I don't think that's your only problem though, as --show-aircraft ought to have listed it anyway.

nick_gentoo - Thanks for the tip about the launcher. If I can't figure anything else out, I'll rebuild it with that.

I did look over the man page and all, but obviously was not able to figure anything out

AJM - I do not seem to have an fgfsrc file anywhere, so I'll look that up and see if it might help.

As for the aircraft name, I had tried S-51, I think, as well as the directory name, and others (of course, I've also tried loading the other aircraft in various ways too). That was all before realizing --show-aircraft was not picking them up in the first place.

Thanks for the replies!

I've decided to just rebuild with the qt5 use flag for the launcher. I imagine in 2020 that's what most people would do anyway. Everything seems to be working now. Thanks for the help!!
