Spring segfaults on load

Posted: 02 Nov 2007, 02:21

It doesn't matter which start script, map or mod I use, my newly-compiled Spring always segfaults while loading.
Recompiled with debugging support-> Looks like it's related to OpenAL, but that's all I can figure out...

Disabling sound makes it not segfault -> problems with OpenAL. I investigate.

Or it's just because it crashes in OpenAL's sound thread which lives in libopenal.so, which probably has been stripped from debugging symbols.

Of course! I'm dumb. Recompiled OpenAL with nostrip:

I think that audioconvert/ac_freq.c was somehow missing while compiling openal or something. Any ideas?

Ok, I tried to investigate this problem for a few days now with no luck. I blame it on lack of C skills ;)
Anyone here who could have an idea? Tobi?

I got this trace when loading XTA 9.2 the other day, it
seems only triggered by very specific .wav's (files that
contain a data-length field in their header whose value
exceeds their actual size in bytes, ionbeam.wav in XTA's
case). Spring guards against such files now, but there's
probably a relation to your version of OpenAL as well (EE
0.173 has never crashed for me despite also bundling a
few of these oddball wavs).

Hi, which version of Spring? I'm running 0.75b2 with openal 0.0.8, maybe I should try latest svn out..

Re: Spring segfaults on load

Posted: 26 Dec 2007, 01:14

A custom SVN build, but it also crashed in 75b2. The
file filter is in SVN revision 5105 and above, be sure to
check infolog.txt for OpenAL messages after testing a
mod (any wavs with this problem will have their header
data dumped there).

PS. for comparison, a test run of XTA 9.2 produces the
following output:

Tried svn rev 5111 and with untouched openal it segfaults with absolute annihilation, and no errors in the infolog about sounds (did not turn on debug though, so I don't know if it is the same problem). :(

I will compile everything as debug tomorrow and see what it gives.

I didn't see that it was the same username lol :P

Hmm, maybe I'm having problems with openal giving any sound now, any of you know if there's a program to test it?

(compiling debug versions of both right now, funny that the ebuild svn always takes the absolute latest version =p)

edit.

Found this bug http://bugs.gentoo.org/show_bug.cgi?id=193147 but instead of changing half of my sound system I ended up compiling openal without the last alsa patch (as posted before) and using oss, as openal alsa support seems really messy with an intel card.

Found out I still need to configure alsa to 44100 Hz so I have created a special user for openal, using the following configs:

~/.openalrc

Code: Select all

#try to make games using 44100 Hz sounds work

# Sound Input i.e microphone

# For use with Intel HDA.
# - Provides full-duplex for the default device via dmix / dsnoop and asym.
# - Forces 44.1kHz sampling rate (instead of 48kHz) for OpenAL compatibility.
#   Note: For this to work "(define sampling-rate 44100)" must be specified in ~/.openalrc also.
#         See http://bugs.gentoo.org/show_bug.cgi?id=193147 for details.
#
# REMEMBER TO STOP ALL APPS USING ALSA AND RUN "/etc/init.d/alsasound restart" AS ROOT!
# Otherwise changes seem not to be picked up correctly sometimes (very confusing ;-)

edit.

aoss seems to work if the apps are run as the same user (probably has to do with the alsa config locking somehow). I have made a spring script that just puts aoss in front and then I've put it in a dir in the beginning of the PATH and set in it springlobby =)

All this seems to work with openal-1.5, and without touching any other configuration file...
