Etch/Feisty Segmentation fault

[Blazeix]

Hi, I'm running Ubuntu 7.04 Beta, and I just installed the full version of VDrift 2007-03-23. When I try to click 'practice race,' 'single game,' or 'network game' I get a segmentation fault. This apparently also happens under Debian Etch. Here are the last few lines of the verbose output

Code:

widget-07: value source not found, default to manual.
widget-07: button action: CarControls
Loading...
Done
gl_car init
Segmentation fault

Hardware Info:
Dell Precision M70 Laptop
Pentium M
1 Gb RAM
Nvidia Quadro FX Go1400 with 1.0-9631 Driver

same here on a Debian Etch (NVidia 9755)

I can confirm this. Just downloaded the minimal package from sourceforge and get the same segfault error. Since the executable does not contain any debug symbol, I can't get a backtrace.

Funny thing is, if I replace the executable with the one I've compiled from svn, there is no error. This is with the same dataset (minimal), same ~/.vdrift config files (created afresh). Seems to me the problem is with the executable file.

I'm running Feisty as well.

rookie1, since you have both access to both the working and broken versions, can you tell me the output of the following command on the one you compiled?

Code:

objdump -x /path/to/vdrift/binary/vdrift | grep NEEDED

I'm imagining that this is due to the OpenGL library having a different filename. It could be issues with the compiler version used to build the package (3.3 and 3.4).

I wish we could have caught these problems with the testing packages before the release. I'll have a new package up to test soon...

[thelusiv]

Here's an attempt at a fix.

http://clemsonlinux.org/~thelusiv/VDrift...-2.package

This package was compiled with g++-3.4 and g++-4.1, instead of 3.3 and 3.4. The idea is that hopefully we'll have less users whose systems were built with gcc 3.2/3.3 than those whose systems were built with 4.0/4.1. I'm not sure if this will even fix the problem, but I seem to remember rookie1 reporting that previous packages worked which were compiled with only g++-4.1. If this works for those of you running Etch/Feisty, and doesn't break things for Joe or anyone else, I will replace the packages in the 2007-03-23 release with some that have these fixes.

So please test this package at your earliest convenience and let me know how it goes

Had the coredump on ubuntu edgy, this fix solved it.
Cheers !

the gtk-installer is now telling me I need libc 2.4 while on Etch, the last libc is 2.3.6

[rookie1]

I get this when running objdump on the executable compiled from svn,

NEEDED libSDL-1.2.so.0
NEEDED libopenal.so.0
NEEDED libGL.so.1
NEEDED libGLU.so.1
NEEDED libSDL_image-1.2.so.0
NEEDED libSDL_net-1.2.so.0
NEEDED libSDL_gfx.so.4
NEEDED libalut.so.0
NEEDED libstdc++.so.6
NEEDED libm.so.6
NEEDED libgcc_s.so.1
NEEDED libc.so.6

For comparison, following is the result of objdump on the release binary,

NEEDED libSDL-1.2.so.0
NEEDED libpthread.so.0
NEEDED libGL.so.1
NEEDED libGLU.so.1
NEEDED libSDL_image-1.2.so.0
NEEDED libSDL_net-1.2.so.0
NEEDED libstdc++.so.5
NEEDED libm.so.6
NEEDED libc.so.6
NEEDED libdl.so.2


I'll download the new package and try it again.

[thelusiv]

Nigo I'm not sure why that is, I haven't changed any of the library checks. I believe the C library check is automatically added by autopackage. I'll see what I can do about that...

rookie1, thanks for that output, I guess it's not just a matter of different filenames.

[Nigo]

it's saying exactly "your copy of 'glibc' is too old for this packet. You need at least the following symbols in 'glibc' : GLIBC_2.4"

while the old packet was installing flawlessly

[rookie1]

ok the new package works now. Out of curiosity, I did a objdump on the new binary as well,

NEEDED libSDL-1.2.so.0
NEEDED libpthread.so.0
NEEDED libGL.so.1
NEEDED libGLU.so.1
NEEDED libSDL_image-1.2.so.0
NEEDED libSDL_net-1.2.so.0
NEEDED libstdc++.so.6
NEEDED libm.so.6
NEEDED libc.so.6
NEEDED libdl.so.2


The only difference from the last release binary is libstdc++.so.6.

[thelusiv]

rookie1, that's good news from the Feisty end of things. Nigo, can you tell me what your default compiler is on Etch? Is it gcc-3.4? For instance on my Ubuntu Edgy machine:

Code:

$ ls -l /usr/bin/gcc
lrwxrwxrwx 1 root root 7 2007-01-02 10:58 /usr/bin/gcc -> gcc-4.1

[Nigo]

I do have libstdc++6

$ ls -l /usr/bin/gcc
lrwxrwxrwx 1 root root 7 2007-04-09 23:02 /usr/bin/gcc -> gcc-4.1

[thelusiv]

Nigo & rookie1, please test the package at the same location again, http://clemsonlinux.org/~thelusiv/VDrift...-2.package

I have updated it. This one is back to 3.3/3.4. Let me know how it works for you.

[Nigo]

it does install but I still got the seg fault :cry:
