Installation EMC on kubuntu 9.4/9.10
Here is one of the sources for information on getting an rtai patched kernel, compiling, and testing rtai. The last two steps outline compiling and testing rtai to ensure that things are working properly as far as rtai is concerned.
mozmck, is it possible you would be able to explain the steps you took to get everything working with the vanilla kernel? I have made quite a few steps, to include disabling the module versioning support. Nothing has seemed to help. From the looks of it, I am following the steps correctly, but I still end up with EMC2 not working.
* soft memlock 20480
* hard memlock 20480
And make sure you have a file under /etc/udev/rules.d/ called 99-rtai.rules (the number on the front may not be 99 - it doesn't matter).
The contents of the file should look something like this:
If you don't have this file you can create it and put the text above in it. You will probably have to reboot after doing this or adding the lines to limits.conf above.
kfontaine: I have attached the config file I used for 188.8.131.52 vanilla. I have a dual-core AMD processor so that's what this config is set for, and I may have stripped out other stuff I didn't need on this computer. One setting you should check is make sure the c++ support in rtai is turned off, and I think it should be turned off in the kernel as well. I remember having some problems with that when I did that kernel, and I believe it was the rtai setting that made it not work. Other than that I think I pretty well followed the steps on the page about installing rtai on debian lenny. If this doesn't help let me know what error you are getting.

Here's a HOWTO for building and installing EMC and RTAI on 9.04 or 9.10:
Anyone given this a try yet? I got pretty frustrated with my previous attempts and had to take a break, but I think I'll give this guide a try. I know that I certainly can't do any worse than I have been.
For anyone running 9.10 I have made some experimental packages which are at www.linuxcnc.org/experimental/Karmic/
This should run on multi-core or single core processors, and is compiled for pentium pro or greater.
I tried the experimental packages on 9.10 and I could install the kernel and rtai part, but I got a problem with the emc2 installation. I get a dependency problem, package "python2.6-xml" is missing. I have python2.6 installed and I have searched the Internet for "python2.6-xml" but failed.
Can someone give me a hint on where to find this package?
This command helps you to find the package name:
aptitude search python | grep xml
This is the output:
~$ aptitude search python | grep xml
p python-4suite-xml - An open-source platform for XML and RDF pr
p python-jaxml - Python module for generating XML documents
i python-libxml2 - Python bindings for the GNOME XML library
p python-libxml2-dbg - Python bindings for the GNOME XML library
i python-lxml - pythonic binding for the libxml2 and libxs
p python-lxml-dbg - pythonic binding for the libxml2 and libxs
p python-wbxml - WBXML parsing and encoding library -- Pyth
v python-xmlbase -
p python-xmltv - allows Python applications to access XMLTV
v python2.5-4suite-xml -
v python2.5-libxml2 -
v python2.5-lxml -
v python2.5-wbxml -
v python2.6-4suite-xml -
v python2.6-libxml2 -
v python2.6-lxml -
v python2.6-wbxml -
It seems to me that I don't have the correct repositories added which include package python2.6-xml or the package name in the error message is not the correct package name.
This is what I get from the package installer.
Error: Dependency is not satisfiable: python2.6-xml
