AttributeError with git versions

[konstin]

I've followed http://www.unknown-horizons.org/download/sources/s-linux/, and here's what I get for the last step:

$ ./setup.py build_i18n && ./run_uh.py

I've installed it on Trisquel today (an Ubuntu-based distribution) and worked fine. Maybe this video helps you: https://goblinrefuge.com/mediagoblin/u/freakspot/m/instalacion-de-unknown-horizons-a-partir-del-codigo-fuente/. Tell us which fifechan and fifengine version are currently installed. --version I think should output that, but I'm not sure. Maybe, you can help with this @LinuxDonald.

[LinuxDonald]

I dont know the command for version info. What i can say is that UH Git version only runs with fife git and fifechan git version. And not with the last stable release of fife.

[MasterofJOKers]

python -c 'from fife import fife; print fife.getVersion()' returns 0.4.0 for me.

On Debian, one could run dpkg -l | grep -i fife to see the package version if installed. If you haven't built your own package, that should return nothing. Otherwise, you probably have the old 0.3.5 version from Debian repositories.

[konstin]

Here's the output of those commands:

$ python -c 'from fife import fife; print fife.getVersion()'
0.4.0+39e8b513
$~/unknown-horizons: dpkg -l | grep -i fife
$~/unknown-horizons:

[MasterofJOKers]

so ... basically, the following does not work for you?
python -c 'from fife import fife; fife.Point(0, 0)'

Could you please run python -c 'from fife import fife; print fife._newclass' and tell me, if it prints 1 or 0?

[MasterofJOKers]

Could you please open "/usr/lib/python2.7/dist-packages/fife/fife.py" and tell me, whats in line 5640 and 5641? The file generated for me should not be able to exhibit the same behaviour as yours. What version of swig did you use? (dpkg -l | grep -i swig)

[konstin]

Lines 5640 - 5641 for /usr/lib/python2.7/dist-packages/fife/fife.py:

        except Exception:
            self.this = this

[MasterofJOKers]

This makes no sense to me. Your AttributeError should be catched by that except right there:

>>> object.__getattr__()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: type object 'object' has no attribute '__getattr__'
>>> try:
...  object.__getattr__()
... except Exception:
...  print "shiny"
... 
shiny
>>> try:
...  object.__getattr__()
... except BaseException:
...  print "shiny"
... 
shiny

On the other hand, if I change my line (which is just except:) to yours, I get the same error. except BaseException: works, too. You should probably re-build fife with the swig2.0 package installed instead of swig3.0.

[MasterofJOKers]

So it seems to be partly fife's fault for having an own Exception class. swig/swig#584 fixes this, which is in swig 3.0.9.

[konstin]

I've manually installig swig 3.0.10. The game now finally works. Though I'm not really satisfied with this solution as you normally don't want to build 4 projects from source just to play a game.

[MasterofJOKers]

Totally understandable. We are working on a new release and on nightly builds.

[squiddy]

I think we can close this one. Looks like an issue with swig 3.0.8 specifically: swig/swig#583
