Use Debian Wheezy insteadUnless you have a good reason to choose Ubuntu, consider Debian Wheezy instead. There is a live+install image customized with RTAI and LinuxCNC 2.6; announcement here: http://article.gmane.org/gmane.linux.distributions.emc.user/52401 To run LinuxCNC on Ubuntu Precise 12.04 with RTAI# Install Ubuntu Precise 12.04 x86 (32-bit). Any flavor should work (regular Ubuntu, Xubuntu, Lubuntu, etc). 64-bit (AMD64) is currently not supported. You can download the installer here: http://releases.ubuntu.com/precise/ # Run sudo apt-get update followed by sudo apt-get dist-upgrade to bring the machine up to date with the latest packages in Ubuntu Precise. # Create a file called /etc/apt/sources.list.d/linuxcnc.list, containing the line: deb http://linuxcnc.org precise base # Add the LinuxCNC Archive Signing Key to your apt keyring by running sudo apt-key adv --keyserver hkp://keys.gnupg.net --recv-key 8f374fef # Run sudo apt-get update again to fetch the package list from linuxcnc.org. # Install the RTAI kernel and modules by running: sudo apt-get install linux-image-3.4-9-rtai-686-pae rtai-modules-3.4-9-rtai-686-pae # If you want to be able to build LinuxCNC from source using the git repo, also run sudo apt-get install linux-headers-3.4-9-rtai-686-pae # Reboot, and make sure you boot into the rtai kernel. When you log in, verify that uname -r says 3.4-9-rtai-686-pae # Create a file called /etc/apt/sources.list.d/linuxcnc-buildbot.list, containing one of these lines (depending on which version of linuxcnc you want): ##deb http://buildbot.linuxcnc.org precise 2.6-rt ##deb http://buildbot.linuxcnc.org precise master-rt ##deb http://buildbot.linuxcnc.org precise v2.5_branch-rt # Run sudo apt-get update again to fetch the package list from the buildbot. This will complain as the buildbot does not sign its package archive. I know, I know, it's on my todo-list.... # Run sudo apt-get install linuxcnc # Machine away! We're interested in feedback on this new, experimental RTAI kernel. Let us know on the emc-users or emc-developers mailing lists if it works, or if it doesn't. |
