Linux segmentation fault

[alphathreethree]

I have bulit from sources on linux (opensuse). When i try to run daemon.i386 it runs through several processes and the fails. Here are the last few lines. Any clues???

Could you give us more information about your system? Hardware specs?

I am running on a Dell optiplex gx260 with an ATI Raedon (cant remember which model, ... circa 2010 model)

Could you post all the output? Also, if you know how to use GDB, a backtrace would be very useful as well.

[alphathreethree]

I have only used gdb a few times over the year (I have always meant to take time to learn it, but ....)

Here is the full output. It all looks correct till the end. Are there some sort of config files or something that I need? The 0.0.0.0 address at the end suggests that.

EDIT: You posted backtrace as I was typing :(

Run the game with ./daemon.i386 +nocurses

GL_RENDERER: Mesa DRI R600 (RV630 9587) 20090101 x86/MMX/SSE2 TCL DRI2
Detected graphics driver class 'Mesa'

Try running with

Code: Select all

./daemon.i386 +set cl_renderer GL

Your graphic card (or drivers) may not be good enough to support the new drivers.

Try to install the open source radeon driver or Catalyst and recompile the game in debug mode (ccmake ... Change CMAKE_BUILD_TYPE from "Release" to "Debug")
Run it like this:

Code: Select all

gdb --args ./daemon.i386 +set cl_renderer GL3 +set in_nograb 1

and when it segfaults, you should see

Code: Select all

 
(gdb) 

There, you should type

Code: Select all

bt

This runs the game with gdb using the new renderer and doesn't grab the mouse so you can move it out in case something goes wrong.

Hope this helps.

I am having some issues getting the new video drivers intalled. I will work that issue tomorrow.
I recompiled with CURSES disabled and the game runs. Maybe its something with the version of ncurses I have. Running gdb with a Debug compile showed the error starts at sys_main.c:772 ... con_curses.c:509 ... then up the stack to libncursesw, ..etc.

The next problem I need to tackle is the fact that when I try to join a server is just sits there "waiting for gamestate".... thanks for your help though.

[alphathreethree]

I installed the ATI drivers from their website, downloaded a fresh copy of the Unvanquished source and recompiled. When I run it now, it doesnt even get far very into the startup sequence.

------ Thanks for all your help. This looks like it might be a fun game, but I have reached my limit. I will try your game again maybe sometime in the future.

[Anomalous]

I see no mention of reboot in there (‘easiest’ way to load fresh kernel taint and also have X restarted to reload any necessary GL-related server-side libs). Anyway, it looks like your X server is missing GLX support.

(My approach would be to dump the taint and use only the open-source drivers. Current kernel and mesa will cope with anything up to and including the HD6000 series, although less optimally; HD7000 is still very much work-in-progress.)
