bz crashes with Segmentation fault

Post by dereliction of duty » Wed Nov 23, 2011 9:56 pm

2.4 was working fine on opensuse 11.4

upgraded opensuse to 12.1 and now bz 2.4 crashes with a Segmentation fault.

I tried renaming ~/.bzf and restarted bz. Bz started, but when I choose to populate the server list, it crashed again. Now it just crashes immediately after starting.

tried debug, but it doesn't appear to list anything other than Segmentation fault

Any ideas or is this a sign to finally (after 10+ yrs) break my bz addiction?

You'd have to build a debug version of the game (by passing --enable-debug to ./configure) and run it within gdb, and then do a 'bt' when it crashes.

Well I'm still on OpenSuse 11.4, but I have heard of a few issues with the new version of the xorg-x11 server and video drivers in 12.1. Some users experiencing graphics weirdness, which was resolved when they down-graded to the version used in 11.4.
Maybe that's worth a shot?
I assume you've looked into downgrading the Nvidia driver to see if that has any effect?

Burned multiple 12.1 dvd/cd's and multiple failed installation attempts,and I finally realized it all had to do with their failed attempt (again) at creating their own, non-proprietary nvidia 3d driver!

installed the proprietary driver (the "easy" way thru one-click install), and 12.1 finally came to life. Haven't checked to see if it installed the older version though.

Don't know if it's needed, but I also blacklisted the nouveau driver. Seems there was something else that had to be done in 11.4 besides the blacklisting but it escapes me now.

I also had to revert back to using an xorg.conf file just to be able to use 1280x1024 resolution - I copied that file from a previous opensuse 11.3 install so maybe there's something odd in there. I've attached that file if it helps.

If there's another way to enable that resolution without using an xorg.conf file I couldn't find it. With my setup, I've figured out it has to do with opensuse not being able to correctly id my cornea mp703 monitor and then list the correct horizsync and vertrefresh numbers, so the xorg.conf file provides the correct hori/vert "refresh" (?) rates as well as list the preferred 1280x1024 resolution.

I searched but didn't find any references to others having trouble in 12.1, then again it comes down on the search term/s used. But with your suggestion Grans, this leads me to believe there could be something screwed up with the video driver setup.

Last time I checked (back when I used some form of Mandrake) I knew something like just 3% of the available linux commands - so I'll stumble thru Blast's suggestion, build it with debug - but the rest of that is greek to me - "and run it within gdb, and then do a 'bt' when it crashes"?

Heck, I'm just happy to be able to get linux working with a gui!

I'll go download 2.4 and build it with the debug option, will be back later if I can't figure out the gdb and bt things.

BTW, this install of bz 2.4 was done using yast. I'll build this next attempt and leave it in my home directory and run it from there.

configure isn't working out so well, ends up with no bz client avail.

Build ares ........: yes
Build curl ........: yes
Build glew ........: no (clients disabled)
Build regex .......: yes
Build zlib ........: yes

BZFlag client .....: no bzflag client binary! (need OpenGL)
BZFlag server .....: yes (with plugins)
BZAdmin client ....: yes

opengl is installed - glxinfo indicates

steve@cyberhome:~/bzflag/bzflag-2.4.0> glxinfo
name of display: :0
display: :0 screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4

Plus alot more info.

I tried some of the suggestions found in these threads but no luck;

http://forums.bzflag.org/search.php?key ... +OpenGL%29

Now I'm trying to build bz with this;

./configure --enable-debug --enable-all-builds

I included the enable-all-builds option trying to get it to include glew to build.

steve@cyberhome:~/bzflag/bzflag-2.4.0> rpm -q --whatprovides glew
glew-1.6.0-6.1.2.x86_64

tried reading thru the config.log but have no clue what I'm looking for.

any suggestions?

Happy Thanksgiving all BTW!

Well... the big thing is that you don't have a C++ compiler installed, thus all the "g++: command not found" errors. :)

Also, we have a README.Linux file. There's a package list in there for Fedora which might be similar on SUSE.

If everything is working with the official nVidia driver, I wouldn't bother building though. The open-source driver is still rather experimental at this point, and I'm sure we try to do stuff that it doesn't support.

I usually build from source as the version in the package repositories is almost always old.

There is a "pattern" in Yast called Base Development which you'll need to install, then the C/C++ pattern too (which will install the g++ compiler Blast mentioned). Then install the openGL dev files (eg glew - just search for opengl in Yast), then download the bzflag source and build it (configure, make install).

I do seem to recall OpenSuse saying they were switching to the nouveau driver by default, but I've always found the Nvidia (proprietary/binary) driver better. I also recall that SAX is broken in OpenSuse 12.1, but I think there is another command line tool which will inspect your graphics and monitor and try to write out a new xorg conf file.

There may be an "nvidia-xconfig" application that would write a new xorg file. Best to ask the SUSE community about how to proceed, though.

Thanks Blast for the heads up and a RTFM! I had that file open actually, but was looking for configure options (as found in the INSTALL file)so I didn't actually read it.

Installed c++, bz compiled and now runs!?!? Sweet!

Yeah Grans, patterns, although I haven't used them yet, I recall seeing something about them in the last few (it seems) versions. I'm not in the habit of building packages (ya don't say!) so the Base Development pattern will come in handy.

I've read there is a sax3 in development now, not sure I'd go the beta route yet though. Unless something else happens, for now I'll leave the xorg.conf file alone.

Tks again all...especially for pointing this gui user in the right direction concerning cli use.

What version of the game? Did you compile it yourself?

if you installed bz that was provided by opensuse, it probably won't work.

I had to compile it from source.

I succeeded to build working game. After installing libcares-devel package, removing whole bzflag build tree (make clean doesn't help), uncomperss and build again with
./configure --enable-ares --disable-ares-build
make
make install

The included in bzflag tree ares source makes the trouble. The game is build with included source, but is running with dynamic linked code from suse 12.1 /usr/lib/

You can't say that with certainty because you were not giving a full backtrace of the crash, just a single piece of the problem.

I am not a programmer, just an experienced user. But the game crashes in /usr/lib/libcares.so.2( I do build in /usr/local/src and instalation in /usr/local/bin ) always in the same place, independently that configure sets "Build ares ........: yes" and "c-ares support: no".
In my first try to build , I was not installed libcares-devel, so configure sets "Build ares ........: yes" .
Then I have installed libcares-devel and tried to force do not build ares and use system library but there was no any result.
So I started from the beginning with already installed libcares-devel and I had success.
