Julian uploaded the package to ubuntu, since I'm not a MOTU and therefore can't do the upload myself. > > As for your instructions: > > Leyendo símbolos desde /home/daniel/easystroke-0.4.9/easystroke...done. > (gdb) run > Starting program: /home/daniel/easystroke-0.4.9/easystroke > [Thread debugging using libthread_db enabled] > > Program received signal SIGFPE, Arithmetic exception. > 0x000000000046e09e in Grabber::XiDevice::normalize_pressure ( > this=0x7fffffffe6d0, ev=...) at grabber.h:94 > 94 return 255 * (pressure - pressure_min) / > (pressure_max - pressure_min); > (gdb) bt > #0 0x000000000046e09e in Grabber::XiDevice::normalize_pressure ( > this=0x7fffffffe6d0, ev=...) at grabber.h:94 > #1 Main::handle_event (this=0x7fffffffe6d0, ev=...) at main.cc:1810 > Cannot access memory in adress 0x7fffffffce98 Thanks, this was very helpful. So your mouse reports 3 or more axes, and easystroke assumes that the third axis represents pressure and is in absolute coordinates, without actually making sure that this is an absolute axis, so there is a division by zero when normalizing the axis range. The solution is to only support pressure if the pressure axis has min < max. I'm curious, though, what kind of device this is and what information the third axis contains. Can you attach the output of 'xinput list'? I've fixed this in git and uploaded an updated package to my PPA, which should build within the next hour or so. Please just install the package and don't add the PPA to your sources.list, as I use the PPA as a dumping ground for all sorts of strange packages: https://launchpad.net/~thjaeger/+archive/ppa/+packages Once xserver-1.7 gets uploaded to lucid, I'll get easystroke 0.5 plus this fix into ubuntu, and after that we can think about a SRU. -- [Karmic]Easystroke: Crash when recording. https://bugs.launchpad.net/bugs/466532 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
