LinuxCNC on Xenomai was created by dinodf
Dear all,
I am trying to compile LinuxCNC for using it on kernel patched with Xenomai. I have successfully builded linux kernel patched with Xenomai on an AMD64 cpu
- linux-3.18.20
- Xenomai-2.6.5
RT work correctly and Xenomai tests pass.

LinuxCNC got from git (linuxcnc-dev) configured and compiled OK, no errors got, but when I run LinuxCNC latency-test it not show anything, Max Interval and Max Jitter all to ZERO!!! and also linuxcnc not run :(

maybe "Linux is compiled to use FPU in kernel-space" is the problem? solution?

AFAIK no current branch of linuxcnc uses Xenomia.
Machinekit does though.

Are you using linuxcnc or Machinekit?

Xenomai is supported, according to the docs.

I have read that docs but no help me.
Nobody have infos for use linuxcnc on Xenomai kernel?
I have also tried "LINUXCNC - 2.8.0-pre1-2771-gdc2ff49" from
buildbot.linuxcnc.org/dists/jessie/maste...reempt/binary-amd64/ but have same problems, I think it depend from wrong kernel's configurations...

You might need to ask on the mailing list, where some of the more realtime-savvy folks hang out.

Hi, same to you, I have installed the relatime kernel 3.14 patched with xenomai on my adm64 i7 cpu. But I have been confused when I build LinuxCNC, According to the building doc on linuxcnc.org, I need to cd debian/, and ./configure [option], for this option should I choose xenomai? just like this: ./configure xenomai， then a message show up: your kernel "xenomai" is not known, There might be needed dependencies which won't get set automatically. Seccessfully configured for 'Ubuntu-14.04'-'xenomai'. And Then I excute: dpkg-checkbuilddeps, be told that dependencies like linux-image-xenomai & linux-header-xenomai &rtai-modules-xenomai is needed. By ignoring this I build the CNC step by step :./autogen.sh ,./configure --with-realtime=usapce ,make, sudo make setuid, . ./scripts/rip-environment, there are no errors. BUT latency-test results is terrible. AND I doubt the steps I excute related to "xenomai", So I would appreciate it if you can give some advices. Thanks.

*Thanks for replying.
*I have compiled and installed kernel-3.14 patched with xenomai-2.6.5, and I also installed xenomai .
*And for this part about installing linuxCNC, I have several questions:1.Before the installation, accroding to the doc , I have to satisfy build dependencies,right? There comes a question, when I enter the Debian\, ### I excute the command: ./configure xenomai, and a message showed "your kernel "xenomai" is unknown,There might be needed dependencies which won't get set automatically. Seccessfully configured for 'Ubuntu-14.04'-'xenomai'". So is normal? ### And when I excute : dpkg-checkbuilddeps, it told me that rtai-modules-xenomai is needed", I don't even know what is rtai-modules-xenomai, I mean that I have installed xenomai. I am so confuesed now.
*So would you like to help me about the questions. Thanks.

Sorry I type "uspace" wrong. But it's not my problem.
