[Xenomai-help] rt_intr_create fails, err = 38 (ENOSYS)

My rt_tasks (periodic) and rt_events work now.
Next I have started using interrupts: rt_intr_create.

It fails with return value = 38 (ENOSYS).

I follow the template from Xenomai's homepage: user_irq.c

In .config I have set: CONFIG_XENO_NATIVE_INTR=y.

Have you any suggestions to solve the problem?
I have noticed that Sarra Risto had the same problem (December 18, 2007).

Are you sure you are actually running the related kernel? At least, it
is one of my favorite mistakes to mess up the built and the actually
installed/execute kernel and modules. To check if the kernel (or the
modules, accordingly) contains those services run

objdump -t vmlinux | grep rt_intr
