Segmentation Fault,

[beltsonata]

Hi there. I'm trying to get the 1.1.0.1 binary to work on Ubuntu 10.04.1 LTS. I downloaded the archive assault.cubers.net/download.html

When I run the assaultcube.sh file, the title screen flashes up for a second before I get a seg fault:

Code:

Using home directory: /home/X/.assaultcube_v1.1 current locale: en_US.utf8 init: sdl init: net init: world init: video: sdl init: video: mode init: video: misc init: gl Renderer: GeForce 7600 GT/AGP/SSE2 (NVIDIA Corporation) Driver: 2.1.2 NVIDIA 195.36.24 init: console init: sound Audio devices: PulseAudio Software, ALSA Software, OSS Software stacktrace: Segmentation fault

I don't actually use PulseAudio, just ALSA. I uninstalled it a while ago as it caused me so much grief. Any ideas if this could be the culprit?

[RandumKiwi]

if you don't use pulseaudio, it could be SDL using pulseaudio... try this:

Code:

sudo apt-get remove libsdl1.2debian-pulseaudio && sudo apt-get install libsdl1.2debian-alsa

[tempest]

^ that.
As you can see in the output, it has PulseAudio listed first, which means SDL will try to use it. But if it doesn't exist, well...

Code:

sudo apt-get remove libsdl1.2debian-pulseaudio && sudo apt-get install libsdl1.2debian-alsa

OK, I've executed the above command which removed libsdl1.2debian-all that I was previously using and replaced it with libsdl1.2debian-alsa.

Unfortunately, assaultcube still does exactly the same, and urbanterror has stopped working, as it relied on libsdl1.2debian-all.

Is there anything else I can try, apart from re-installing pulseaudio, which makes my system inoperable?

I think I've found a solution. Appears that AC checks for an "openaldevice" alias (hidden somewhere in soundmanager.cpp).

You have to add this line somewhere in init.cfg (NOT in saved.cfg or autoexec.cfg!):

Code:

alias openaldevice "ALSA Software"

However, the problem is that this line is overwritten every time AC quits. So you'll either have to remove write permission for init.cfg or use a shell script that does something like

Code:

echo >> ~/.assaultcube_v1.1/config/init.cfg "alias openaldevice \"ALSA Software\""

after AC has quit. Of course, the most convenient place would be assaultcube.sh (if you're using it).

OK, I've run

Code:

echo >> ~/.assaultcube_v1.1/config/init.cfg "alias openaldevice \"ALSA Software\""

and also put that command at the end of the assaultcube.sh file. Is this what you mean?

assaultcube is still seg-faulting at the same place.

[tempest]

Hmm. Weird.
Try running it in GDB and see what you get.

Code:

gdb --args bin_unix/linux_client --home=${HOME}/.assaultcube_v1.1 --init -r -t0

(of course you'll have to cd to AC's main directory first)

But before that, make sure that that stuff is really executed:

Code:

echo >> ~/.assaultcube_v1.1/config/init.cfg "alias openaldevice \"ALSA Software\"; echo works"

then run the game, and now you should find works somewhere in the output (even if it doesn't work :S).

[beltsonata]

Ok here's the gdb output

I've altered the other files like you said, and 'works' does indeed appear. It's still crashing though...

I'm a bit new to memory debugging so if there is anything else I can try, please let me know. :)

Have you read ACwiki:Sounds and ACwiki:Linux Support - you might have better luck with OpenAL-soft than with the regular OpenAL .. but maybe you haven't even gotten that installed, it should be available from the ubuntu repositories for your release so compiling from source would only be required if your systems fails with the regular OpenAL instance. HTH

[tempest]

For now, you can change audio 1 in init.cfg to audio 0, so AC will at least run (without sound, of course).

Other than that, IDK. You can try installing debug symbols for ALSA. Other than that, I'd say you should better ask on the Ubuntu forums, as this seems more like an OS+Driver+HW bug. Also, the guys there definitely know a lot more than I do.

[beltsonata]

Problem solved! I installed alsoft-conf from the repositories, removed pulse audio from there, and now it's working, sound and all.

Okay, now I wouldn't call that bunch of errors "working", but if it works, who cares :D
