int main()
{
    auparse_state_t *au;

    au = auparse_init(AUSOURCE_LOGS, NULL);
    if (au == NULL)
        exit(1);

    if (!ausearch_set_param(au, "auid", "=", "500", AUSEARCH_STOP_EVENT))
        exit(1);

    while (ausearch_next_event(au)) {
        if (auparse_find_field(au, "auid")) {
            printf("auid=%s\n", auparse_interpret_field(au));
        }
    }
    auparse_destroy(au);
}

I tried the above program for but after compilation its giving following linking error.
