can you reproduce this bug?

which mod have you been running?

did you move a kbot belonging to aai in the range of a tower of another aai player?

thx for your help :)

It's xect vs myn mod, slated to be included in the GPL compatible package of spring.

All involved versions are SVN of yesterday.

I could reproduce it with other units attacking AAI, seems to be that it crashes once a unit dies, of either side.

Botlog isnt written.
I looked in

AI/AAI/log/AAI_log_team_*

"It's xect vs myn mod" - lol, my brain somehow must have been deactivated before posting...

does it happen with other mods as well?

since you can reproduce it (and attacking other units normally happens quite often) there must be some general problem (maybe only linux related - otherwise win users should have been facing that bug multiple times as well)

XTA works 100% flawless. This is a weird segfault, I recompiled with optimize=1, same segfault, in that damage function.

hmm i tested it with win xp, no result - everything seems to be fine...

i dont have a linux environment to test it though. can you trace the crash and tell me where exactly within UnitDamaged() it occurs?

pheldens · Post by **pheldens** » 28 Sep 2006, 22:04

how do I do this?

Isn't that backtrace enough?
I just noticed some errors in infolog.txt:

Code: Select all

GlobalAI1: Error: Could not load mod and/or general config file, see .../log/AILog.txt for further information
GlobalAI1: AAI not properly initialized, please view ai log for further information
User exited

(".../" is nonsense)
(today's svn for all versions involved)

Build spring with debug turned on via scons

gdb spring
run
bt full (when crash)

Recommend running spring in window

Alternative use UnityLobby Debug Option in Battle Section to make a backtrace ( tvo added that ). Still need to compile spring with debugging though.

ehm that means that aai is just not set up properly. most of the time this is caused by missing config files or typing errors in cfg files. look at the log file for more information

anyway i dont know what happens if you play against an uninitialized instance of aai. in best case nothing, in worst case it crashes

Can you fix the svn version submarine?

<moot>

Excuse me, that worsening was caused by a corrupt datatree somehow (unless something changed in svn this afternoon), I started from scratch and XTA works again.

The initial problem remains.

Code: Select all

GlobalAI1: Error: Could not load mod and/or general config file, see .../log/AILog.txt for further information
User exited

once again: ".../" is nonsense on unix, so I cannot inspect any bot logfile.

ah, this time the aai logs are updated properly, but on the teamlocation, and not as indicated in the error string.

> less AI/AAI/log/AAI_log_team_1.txt
AAI 0.70 running mod Xect-vs-Mynn.sdd

Mod config file AI/AAI/cfg/mod/Xect-vs-Mynn.cfg not found

@pheldens If you find a fix please post it as a patch so it can be commited.
