how to make examples on beginner's guide to run on rtai-3.2 with 2.4.27kerne

[weiyun lv]

I have made the first example(fifo) run. Now the second using shared memory, 
when I try to compile scope.c

$ gcc -o scope scope.c
it says that :  rtai_shm.h: No such file or directory

inside scope.c the including lines like this:
#include <stdio.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/mman.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <signal.h>
#include <rtai_shm.h>
#include "parameters.h"

can anybody tell me where the compilor try to get these head files.
