Flight gear crashes on startup since 2.6 [SOLVED]

Question

there are two problems I started having immediately after updating flight gear to 2.6.
when I type fgfs, it gives me an error:
ERROR: The path '/usr/lib/FlightGear' does not exist in the file system.
Base package check failed:
Version [none] found at: /usr/lib/FlightGear
Version 2.6.0 is required.
Please upgrade/downgrade base package and set the path to your fgdata
with --fg-root=path_to_your_fgdata
I can temporarily solve this by running fgfs with
fgfs --fg-root=/usr/share/flightgear/data
so after running that and getting past the initial error, I get a segmentation fault.:

on the flight gear loading screen, the toolbar at the top appears, and after the message at the bottom says loading scenery, it closes and this is what I see in the terminal. I have a geforce 8600gts with nouveau drivers.

Answer 1

looks like libpng issues in the second part. Do you have anything from AUR you did not rebuild when the libpng updates hit the repos? such as cairo* packages? Just a shot in the dark on that one?
I have not upgraded my PKGBUILD yet to 2.6 yet so I have not run into this. I will try updating mine later tonight and see if I run into a simlar problem.
whereis fgfs
should show if you accidentally have more than one version on the system. I know that happened once when I was still on Debian.
info about the first error you had
https://code.google.com/p/flightgear-bu … ail?id=381
I use the nvidia blob on my system. Hope this might help some, I will post later tonight after updating my install to see if I run into the same issue.
EDIT:
Well I updated and did not run into the same issues that you did. Everything seems to be working for me, minus my own personal patches(which I expected). It loaded and ran everything as expected and I did not even run into the first error you had to work around. Maybe try a reinstall or remove FlightGear then install again
Sorry I could not be of more help. Hopefully was just some package in your AUR stuff that gave you the issue and you're already flying
