Hi Marty, thanks for your bugreport.

Can you try starting widelands from console/terminal and provide the output here?

widelands_stdout.txt Edit (8.5 KiB, text/plain)

I also build widelands from source. Same result. See the attached log file.

Additionally (but different issue): The Wiki instructions may be wrong. See line 11 of the log file.

Do you know gdb? You might install it and then run:

gdb ./widelands
run # after some seconds when you get prompt
bt # when the game crashes and you see prompt again

and copy the backtrace you just got

It would be convenient for you if you run windelands in window mode when trying this..

Well this points to a sound. I am not expert here, but can you try with --nosound option? (I hope there is such option)

What do you mean? Command line option? Or compile option (for I build it also from source)?

Ah! Command line option works!
widelands --nosound

No it loads the world without crashing!

command line option, should be like this:
./widelands --nosound

or try
./widelands -h
for more info

But this is of cause just a work-around.

How are things going on?

It is still possible that the problem is not on widelands side.

If you are willing to invest your time, you can compile the game by yourselves and see if sounds works there... and as a bonus you will have newest version...

I can confirm the crash now. Since i had never had any problems right now, the culprit is the last update of SDL2 which i did yesterday:

From pacman log:
[2017-10-02 19:11] [ALPM] upgraded sdl2 (2.0.5-4 -> 2.0.6-1)

Downgrading to the last version (2.0.5-4) solved the crash (no recompilation needed).

Marty, can you try also downgrading the sdl2 package?

I will try to find related upstream bugs.

[martin@Lifebook ~]$ sudo pacman -U 'Downloads/sdl2-2.0.5-4-x86_64.pkg.tar.xz'

... worked!

Now it starts without problems! Thank you!

There is a discussion in the SDL forum:
https://discourse.libsdl.org/t/sdl-2-0-6-released/23109

Building SDL2_mixer from source with the latest changeset might fix the issue: https://hg.libsdl.org/SDL_mixer/rev/d3fa63933df2

Thanks for reporting. Now that SDL2 2.0.6 has landed in Ubuntu artful (the current development version due to be released shortly), that is affected by this issue too. I've reported bug 1722060 to follow up this.

I see the crash as well under mac os x using

- sdl2: stable 2.0.6 (bottled) and
- sdl2_mixer HEAD-e6fa426a79dd_1, i.e. build from head. my Revision is after the one mentioned in #16.

Installing sdl2 also from HEAD seems to fixes the issue:

- sdl2: HEAD-db7ee6a1ba6a

Don't know what 'head' means on mac, for arch linux the sdl version sdl2-2.0.6-2 does not solve the problem.

Confirmed on Manjaro Xfce.

downgrading package "sdl2" to 2.0.5-4 solves the issue here.

Upgrading archlinux today solves the problem here:

upgraded sdl2_mixer (2.0.1-1 -> 2.0.2-1)
upgraded sdl2 (2.0.5-4 -> 2.0.7-1)

Workaround added in r8662 that will switch off the sound backend for SDL 2.0.6.
