Giorgio,
you cannot use standard library functions in your modules.
You can use functions of your own or ones provided by
kernel (man ksyms). On this mailing list, it was mentioned
that it's possible to use math functions (-lm) in the
modules. I try to do it but not final results till now.
If using fp operations in your RT task, don't forget to let
it know about it. To link your module with a library, you'll
need to use ld -r ... (partial linking).
Reagards,
