[SOLVED] xmoto crashing since kernel 3.13

hi everyone,

since the kernel update to 3.13 the game xmoto is not running anymore on my machine. it starts normally but when i enter a level and the bike touches a solid object the game crashes, always. the stderr message on the terminal is:

ODE INTERNAL ERROR 1: assertion "bNormalizationResult" failed in _dNormalize4() [odemath.h:42]
Abgebrochen (Speicherabzug geschrieben)

the last line is german and means something like: stopped (memory snapshot written). my specs are:

Intel Xeon E3-1245 v3
Radeon HD7750 with free radeon driver
uname -a -> Linux $$$$ 3.13.5-1-ARCH #1 SMP PREEMPT Sun Feb 23 00:25:24 CET 2014 x86_64 GNU/Linux
pacman -Ss xmoto -> community/xmoto 0.5.10-4 [Installiert]

does anyone know what this could be?

I get the same error on an Intel card.

ODE INTERNAL ERROR 1: assertion "bNormalizationResult" failed in _dNormalize4() [odemath.h:42]
Aborted (core dumped)

Run

LC_ALL=C <command>

to get the output in English.

Re: [SOLVED] xmoto crashing since kernel 3.13

I've noticed this problem as well.

However, it looks like the recent ODE physics library update to 0.13 broke Xmoto.

It seems the solution is to downgrade the "ode" package to version "0.12-5". The "downgrader" tool in AUR works good for that and then its just a matter of preventing pacman or yaourt from attempting to upgrade the package again by adding it to "IgnorePkg" line in pacman.conf.

Might be a good idea to report this bug to Xmoto upstream.

Re: [SOLVED] xmoto crashing since kernel 3.13

thanks for the hint, Xaero_Vincent.
after downgrading ode to 0.12-5 xmoto works again. what i did was downgrading the ode package by

pacman -U /var/cache/pacman/pkg/ode-0.12-5-x86_64.pkg.tar.xz

and blocking the package from upgrading in the pacman.conf with

IgnorePkg = ode

. the problem is already reported: http://todo.xmoto.tuxfamily.org/index.p … ask_id=809

Hi

I don't mean to resurrect this thread; just to append that xmoto seems to be still broken, and the bug far from fixed, so I bundled latest xmoto package with ode-0.12-5-i686.pkg.tar.xz (from the Archlinux Rollback Machine) into an AppImage, and you can download it here: http://www.portablelinuxgames.org/?id=xmoto

Re: [SOLVED] xmoto crashing since kernel 3.13

today the package of the latest xmoto version came out.
now xmoto won't start with the old ode-version (0.12-5).
but with the latest ode version (0.13) everything is fine.
