Hi,
I think that the problem is due to the fact that the rtai modules are
not in one of the standard paths known to depmod.
You can either use insmod in the rtai directories and this should work
fine, for example:
insmod rtai
insmod smpscheduler/rtai_sched_8254
insmod newfifos/rtai_fifos
or alternatively if you want to use depmod you can install the rtai
modules in the misc directory, for example:
install -c -m 644 rtai /lib/modules/<your_kernel_version>/misc
install -c -m 644 smpscheduler/rtai_sched_8254
/lib/modules/<your_kernel_version>/misc
install -c -m 644 newfifos/rtai_fifos
/lib/modules/<your_kernel_version>/misc
Afterwards the depmod -e should not show any unresolved symbols, and
insmod of the rtai module name(s) should work from any directory,
Best regards,
Steve
