System call


Hi!

Like most of the people here i've a problem. I'm trying to create 2 new systems calls. First of alli've got to say i've compiled a new kernel : i had the RH9 and then i put a new kernel 2.4.18 from kernel.org in order to do some modifications.

For creating the sysem calls i modified unistd.h, sys.c and entry.s. Then after compiling it i make a _syscall3 (whith arguments) in a very little c program,then i try to compile it but it says : "`__NR_cosched' undeclared (first use in this function) " .
Somebody said me something about a link in /usr/src , any idea ?

Someone help me !!!!

Thanks in advance !!
