LinuxCNC on 12.04...got error, what does it mean? was created by greenbuggy
I was getting a few unexpected realtime errors while tuning my system on 10.04 and read that Xenomai and 12.04 works better on newer processors and mainboards so I updated to 12.04LTS and followed the instructions here:
www.anderswallin.net/2012/12/linuxcnc-on-ubuntu-12-04lts/
to get Xenomai and synaptic on my system
Now when I attempted to start linuxCNC it tries to start then I get this error in my linuxcnc_debut.txt
This in my linuxcnc_print.txt:
I've attached my config files. Machine is running on a WTM D28 mobo with an Intel Atom 1.8, 2G ram, 500 GB HDD, Mesa 5i20-PCI.
I'm fairly new to linux so I'm not sure exactly what I did wrong here, or how to go about fixing it.
If its beyond fixing or better to do a fresh install of Ubuntu 12.04 then xenomai and compiling LinuxCNC I can do that, and don't mind being told that I should go back to 10.04 but I'm curious what I did wrong such that linuxCNC won't start, so I can learn from my mistakes. Thanks for the help.

Hi
Unfortunately from those little snippets of error messages can't tell anything.
You need to run from a terminal and post all the output plus that from the /var/logs/kern.log
For info though, 10.04 runs very well on Intel Atoms, has some of the lowest latency figures you will find for newer boards. (typically sub 10K sometimes down to 5K)
Xenomai and 12.04 runs better on my quad core machine than 10.04 and the stock rtai kernel did, but Xenomai runs horrendously on a P4 I tested on
So it is not a silver bullet, there are horses for courses
regards

Third try is the charm maybe....BTW Moderators "editing" and adding a file doesn't seem to be working

Hi
From what little info there is at present I suspect your build is the problem.
Either the libraries are not built properly to be dynamically loaded or , because you have built in your home directory, there is no path to them in the environment.
You can either build with -rpath=/path/to/library/ or try to do it afterwards by adding the path to LD_LIBRARY_PATH and / or add the paths to ~/.bashrc
Look up that error message in google for more info
regards

Was this a liveCD installation, or something built from source?
