Nightly not starting

[dom_vc10]

Hi

Strange issue today. I am using the PPA from Saikrishna Arcot https://launchpad.net/~saiarcot895/+archive/ubuntu/flightgear-edge for the nightly builds. I run all updates today in the linux mint update manager. When I click on the flightgear icon from the start menu nothing happens at all. Maybe it's a temporary issnightly build however it's strange nothing at all happens, no errors, warnings etc.. Anyone else having the same issue?

System specs:
Linux Mint 20.1,AMD Phenom II X4 965,16gb ram,GTX 1050 Ti 4gb

what happens when you try it from the command line instead of clicking icons that hide things from you?

fgfs --launcher

Note that the data package you're currently getting is probably out-of-date, I need to fix that up.

I get this ..

Code: Select all

fgfs: symbol lookup error: fgfs: undefined symbol: _ZNK7simgear3pkg4Root11allPackagesEv

Does the above output relate to what you are thinking?

I suspect this is because FlightGear was updated but SimGear was not. I pushed a change to the signature of simgear::pkg::Root::allPackages() just yesterday, it sounds as if one or the other piece did not get rebuilt.

ok thanks all I will hold on for a new update then, thanks for all the responses

Basically this.

The way it's currently built, FlightGear and SimGear are separate packages and built separately (SimGear is built as a shared library). In addition, FlightGear doesn't get rebuilt after a change to SimGear. Because of that, every once in a while, there's some undefined symbol error because a function declaration changed.

All makes full sense to me know, thanks all

Just updated and FG launches yes!! Thanks.. One new issue is when I hit the fly button on the gui I get an error "cannot open timezone file
at /usr/share/games/flightgear/Timezone/timezone16.bin"

I looked into the path shown and that file does not exist. Does this mean a new install is needed?

[wkitty42]

that's a recent update to FGData... that should be updated, as well...

[saiarcot895]

So in my packaging (and in the packaging that Ubuntu/Debian does I believe), the Timezone directory is replaced with a symlink to /usr/share/zones, since timezone data would already be installed there on Linux systems, and all applications should be using that data anyways. However, it looks like there's now a timezone16.bin file that FlightGear is using.

I think I'll remove that symlink for now and keep the contents there, since this .bin file is a preprocessed file combining data from the timezone database, OSM, and Natural Earth.

I just saw there was an update and applied it however there's no change, was it updated or it's on the still to do list?

[saiarcot895]

It's not yet updated. It'll be updated around Sunday evening/Monday morning.

[dom_vc10]

Thanks that's great. Also many thanks for your PPA's it makes my life so much easier I have always failed miserably at building FG myself

Still getting the message that /usr/share/games/flightgear/Timezone/timezone16.bin is missing.
