Hello, everyone,
My OS is lubuntu 17.10. My board is a x86_64 platform with ATOM CPU.
I installed xenomai 3.0.6 with linux 4.1.18. Xenomai latency test is ok.
The main question is why Xenomai and why that version?
Xenomai is not good enough for software stepping on x86 and 3.0.6 is
quite old, the BBB uses 3.18
I build machinekit from source:
cd src
./autogen.sh
./configure --with-xenomai --with-xeno-config=/usr/xenomai/bin/xeno-config
from the "configure" output, I can figure out that xenomai user space
is used.
but when I run "sudo make setuid" "source ./scripts/rip-environment"
"machinekit"
I just can't start it normally.
The output info is below. Can anyone help? Thanks!
I did not change anything else.

This is telling you that rtapi_hal_posix does not exist
Given that you are supposed to be running a xenomai kernel, then
something is screwed up.
The most obvious cause, could be that whilst you built a xenomai kernel,
you have not booted into it and are still running a posix kernel, for
which you did not build
because you specified the kernel to build for as xenomai
