I don't think it's a problem with the compiler. There have been changes to the
BrickOS code over the years.
I know the value sys_time has been replaced with the function Get_sys_up_time().
You should be able to add this line at the beginning of the code:
#define sys_time Get_sys_up_time() // v10 does not have sys_time
Or, maybe that would do other bad things. You could just replace sys_time with
Get_sys_up_time() everywhere in the code.
And, I just went looking through the new code. I think 'pid_t' was replaced with
'tid_t'
Make those changes in your program (seeker), and you should be good to go.
