i am really new to linux and thus RTAI

i am tryin to run the following program:

/* led1.c, an LXRT LED blinker */

#include<pthread.h>
#include<rtai.h>
#include<rtai_lxrt.h>
#include<sys/mman.h>
#include<sys/io.h>

// delay in nanoseconds
#define TICKS 500000000

main()
{
        RT_TASK *task;
        int priority = 0, i;
        int stack_size = 4096;
        int msg_size = 0; // use default

        // get enough privilege to
        // access the I/O ports.

        iopl(3);

        task = rt_task_init_sched(nam2num("main"),priority, stack_size,
msg_size);
        if(task == 0) exit(1);
        rt_set_oneshot_mode();
        start_rt_timer(0);
        mlockall(MCL_CURRENT|MCL_FUTURE);
        rt_make_hard_real_time();

        for(i = 0; i < 10; i++) {
                outb(0xff, 0x378);
        rt_printk("1");
                rt_sleep(nano2count(TICKS));
                outb(0x0, 0x378);
        rt_printk("0");
                rt_sleep(nano2count(TICKS));
        }
        // back to non-rt land!
        rt_make_soft_real_time();
        stop_rt_timer();
        rt_task_delete(task);
        return 0;
}


i compile it as folllows:

gcc -I /usr/realtime/include -L /usr/realtime/bin/ -o a4 a4.c -lpthread
-llxrt


errors:

i tried browsing the CVS repository but i find it difficult to understand.

i need to browse simpler programs i feel....a simple program with a thread
that print "something" and "another thing" with some delay ....  kindly
guide me.....i am ready to put in efforts just dont see a direction

one more error i keep getting is

*error while loading shared libraries: liblxrt.so.1: cannot open
**shared object file: No such file or directory*

i need to add some PATH some linker error to resolve but cant understand
where to do what

kindly guide me
