I quote an earlier reply of Gilles on a similar issue:

"You have probably missed the following message when running "make
install":

*** Warning: you are not super-user and sudo does not work, real-time devices
*** nodes will not be created.
*** If you do not create these devices by hand, Xenomai test programs will not
*** work.
*** To create these devices please run "make devices" with super-user
*** privileges."

Best regards,
