Hi Steve,
Thanks, you were right about the compiler being ok. I changed "pid_t" to "tid_t"
and got the thread statements working correctly. Finally, by consulting BrickOS
documentation I found out the new syntax for the old "sys_time" command is
"get_system_up_time()". I added the line
#define sys_time get_system_up_time() to Seeker.c and then it compiled ok.
Thanks a lot,
Marcelo
