are you using python 2 or python 3?? there is a huge difference in the details of the interpreted code between the two versions... IIRC python 2 is needed for FGO whereas python 3 is needed for FFGO...

Indeed! Try:
Code: Select all
python2 fgo


Or checkout FGo's predecessor FFGo, which runs on python3

@murderbybox:

wkitty42 is right, the error message you posted is typical of Python 2 code run with Python 3. If you want to run FGo!, you have to use Python 2.x as indicated on its home page. Some distros, such as Archlinux IIRC, made the strange choice of pointing the default “python” executable to Python 3, whereas it had “always” meant Python 2.x; this change broke compatibility for all programs relying on the “python” executable from the PATH. Therefore, in order to run FGo!, maybe you need to change the “#!/usr/bin/env python” line at top of the fgo script to “#!/usr/bin/env python2”. Another way would be to explicitely run something like “python2 /path/to/fgo” whenever you want to run it (maybe create an alias or a script for that), as suggested by chris_blues.

Erm, I have the impression “predecessor” doesn't fit well here, chris. :wink:
By the way, since this thread is being revived, all problems and feature requests reported here since I started to read it (2013 or so?) have been addressed in FFGo, to the best of my knowledge (plus new features, the one I am currently working on being a dialog to find all airports located at distance d from a given airport, where you can choose the lower and upper bounds for d---this should be convenient in order to quickly choose an airport that is neither too close nor too far from the airport/area controlled by an ATC operator).

Do you have python-imaging-tk installed? Maybe it's missing?

This thread is dedicated to FGo!. Since your message is about FFGo, I have replied in the thread dedicated to FFGo.
