Ah, I believe that is a package that went away in 9.10. Try downloading it from here and installing it: packages.ubuntu.com/jaunty/python-xml

I think that's what I had to do to get it to work.

Thanks,

This package worked. The package name is python-xml, version 0.8.4-10.1ubuntu2.

I have now installed emc2 on 9.10.

To get emc started I had to create /dev/rtai_shm and /dev/RTAI_SHM.
sudo mknod /dev/RTAI_SHM c 10, 254
sudo ln -s /dev/RTAI_SHM /dev/rtai_shm

But I can only start as root. Non root user gets

Can't write to /dev/rtai_shm - aborting

I tried to change permissions on both files above, but /dev/rtai_shm gets changed back to

crw-rw---- 1 root root 10, 254 2010-02-19 22:14 rtai_shm

as soon as I test with
/etc/init.d/realtime start

I also created udev rules and placed them both at /etc/udev/rules.d/ and /lib/udev/rules.d/ but no change.
$ more /etc/udev/rules.d/99-rtai.rules 
KERNEL=="RTAI_SHM",SYMLINK="rtai_shm", MODE="0666"
KERNEL=="rtf[0-9]*", MODE="0666"

I suspect it has something to do with udev!
I need help.

Thanks Janne

Make sure you have the following two lines in the configuration file /etc/security/limits.conf, and add them at the end if they are not there.

* soft memlock 20480
* hard memlock 20480

Then you'll need to reboot, and this should allow you to run as a normal user.

I recently bought a new laptop and installed Kubuntu 9.10 on it.
I've been trying to reinstall the EMC2 Simulator with no success
to date. I went to:

emc2-buildbot.colorado.edu/~buildmaster/

loaded the appropriate APT line into my package manager and
attempted to load the emc2-sim package. I get the following compliant:
The following packages have unmet dependencies:
  emc2-sim: Depends: python (< 2.6) but 2.6.4-0ubuntu1 is to be installed
            Recommends: hostmot2-firmware but it is not installable

Given that these are supposed to be Beta packages for 10.4, I thought
I would ask if this issue has come up before?

Any help would be appreciated,

-Wayne
