So this has been very helpful so far, but I have run into a couple snags. Spent most of today on this and got the kernel with PREEMPT-RT installed successfully. Peter, I did use your config file. Much thanks.
Now to the linuxcnc part, I've run into a block with "sudo apt-get build-dep linuxcnc", getting an error "E: Unable to find a source package for linuxcnc". Tried adding these lines to /etc/apt/sources.list, but it didn't help... deb http://www.linuxcnc.org/ lucid base linuxcnc2.5 deb-src http://www.linuxcnc.org/ lucid base linuxcnc2.5 Yes it does refer to lucid, but I don't know what to put for ubuntu 14.04. Section 2.2 does not list that line though, so I thought I'd proceed without for now. Got further, but when I try to "make" (after ./configure --with-realtime=uspace ), I get this: Makefile:71: Makefile.inc: No such file or directory. Makefile:82: *** Makefile must specify RTPREFIX and other variables. Stop. What am I missing here? Is this related to the "sudo apt-get build-dep linuxcnc " issue? Thanks, -Neil.
