run Linuxcnc on xenomai with EVL(the realtime core)

Hi, I'd like to ask how to run LinuxCNC on a system with Xenomai 4  installed (Debian 12).
I installed LinuxCNC using which is how I did it on a Debian 12 system with the preempt-rt patch, and it worked fine there. However, now with Xenomai 4, when I try to run LinuxCNC, it gives me a note: "Note: Using POSIX non-realtime". Does this mean I'm not leveraging Xenomai's real-time performance?
I'm sure my Xenomai installation was successful.

Since there are few tutorials for Xenomai 4, I'm not sure what the correct steps are. My current guess is that I need to run it in the evl environment, which means I need to run it in root mode (sudo su). However, when I tried that, LinuxCNC gave me an error and didn't allow running in root mode.
So, I'm wondering if there's a way to solve this problem, or if there are any parameter settings that can make LinuxCNC run in the real-time core of Xenomai 4.
How can I run an application using the EVL core?
Thanks a lot!

No double posting.

Is there any particular reason to use Xenonai?
Probably compiling it might work, but i never tried it.

I'm really sorry for the double posting. The first time I tried to post, my webpage crashed, and I thought the post failed.

I'm using Xenomai for some experimental testing. I've already completed my tests on a preempt-rt system, and now I'm moving on to testing with Xenomai. Unfortunately, I've encountered a lot of difficulties, so I'm hoping to get some advice and help from everyone.

You'll have to build Linuxcnc for Xenomai.

There maybe some notes in the docs, maybe Andy might chime in.

The packages you downloaded are for the RT kernel.

I just tried it. I rebuilt LinuxCNC as the documentation said

The most commonly used arguments are:

Code:

--with-realtime=uspaceBuild for any realtime platform, or for non-realtime. The resulting LinuxCNC executables will run on both a Linux kernel with Preempt-RT patches (providing realtime machine control) and on a vanilla (un-patched) Linux kernel (providing G-code simulation but no realtime machine control). If development files are installed for Xenomai (typically from package libxenomai-dev) or RTAI (typically from a package with a name starting "rtai-modules"), support for these real-time kernels will also be enabled.

I take it you ran the linuxcnc as a RIP ?
