I would like to mention that i am getting this failure also in "make rtai" step.
Can you please guide me step by step how can I fix the issue?
Thank you!

Hello,

After configuring and building your Xenomai kernel, have you correctly installed the libraries?

[Florian95]

Hello,
What libraries should be updated?
Also, xenomai is no more installed by it is showed in the documentation/steps to do.

[S.Grosjean]

Hello,

This driver only supports the RTDM interface, as offered by RTAI and Xenomai 3.x.

There is no Xenomai 4 EVL driver support at the moment.

Regards,
