Yes! After a week of back-and-forth with the Xenomai fellows (Gilles is
great, very responsive, and wizardly) and countless builds of several
versions on two distros, my head is spinning, but we've fixed a whole
slew of problems to produce a one-size-fits-all Xenomai kernel build
that should run on almost anything x86, just as your favorite distro's
kernel packages are able to run on nearly any hardware.
At this point, we have a well-documented set of minimal kernel config
changes for Xenomai that can be applied on top of RedHat-like or
Debian-like kernel configs. Gilles is re-releasing Xenomai 2.6.2 with
some of the fixes we found back-ported, and those fixes are available in
his dev tree right now, of course. And we have working RPM kernel
packages, and the Debian kernel packages build, install and boot;
unhappily there seems to be one last regression test failure, but I
expect that will be solved quickly.
All you folks itching to compile LinuxCNC on Precise, keep an eye out in
the next few days for a shiny new set of Xenomai kernel packages!
John
