Demo segfault at start

**dadar** · 09-10-2010, 09:08 PM

Hi,

I've been trying to execute the game demo but it just crashs with a segmentation fault.
I have "chmod -R u+rwx AmnesiaDemo/" directory to be sure there is no permission problem but it doesn't change anything.

Here is my hpt.log
It seems not very informative about the problem.
Since I got only 512Mb of ram and game requires 4Gb, this might be the problem ?

Can I launch Amnesia.bin or Launcher.bin in gdb or strace to give more information ?
This is subject to EULA decompile clause ?

I missed something.
here is hpl.log

**Urkle** · 09-11-2010, 07:30 PM

Is there any further information about the crash? Can you try looking at the last output of dmesg?
And does the launcher even run??? And yes, please run the launcher through gdb and give me a stack trace if that is the program crashing.

There is no further info. Both penumbra overture and penumbra black plague demo were working fine.
No dmesg output or anything in /var/log related to the segmentation fault.
From the backtrace, it seems it may be a problem with openal or alsa. So I reinstalled those. It doesn't fix anything. This is :
alsa-lib-1.0.21a
openal-1.11.753

Here is an strace of Launcher.bin at the end (truncated because it is 600k, above upload cap limit)

I'm having the same or a similar issue.

Launcher works. Seg fault on launcher exit/game start.

Here's dmesg: (three attempts to run)

Any ideas?

From that it looks like the game can't write to your home directory.

Can you check that the ~/.frictionalgames/Amnesia/MainDemo directory exists?

I did. The permissions looked proper (for my user and default group), but to check I went and added world write permissions... lo and behold the game started. I'll let you know if I run into problems...

Curious though... how did you catch the write permission issue? fclose() on libc in the GDB trace or the DMESG errors?

**Urkle** · 09-25-2010, 04:56 AM

the gdb trace.
When the game starts up it writes a small file and then after the graphics are initialized it removes the file. It's used to "detect" when the game crashes due to graphics driver issues and resets the configuration to the default if the file still exists on startup.

There is an updated version of the demo coming soon that will fix this and several other crashes.
