Ada question:

code:

with Ada.Real_Time;
...
Poll_Time  : Ada.Real_Time.Time;
Period     : constant Ada.Real_Time.Time_Span := 
                          Ada.Real_Time.Milliseconds(10);
...
-- Not sure why this won't compile
Poll_Time := Ada.Real_Time.Clock;
delay until Poll_Time + Period;
...

This won't compile, because it claims that there is no specification for the "+" operator. Looking through the Ada.Real_Time package, the "+" definitely is overloaded for both Time types on the left and Time_Span types on the right, and vice versa.

I've withed Ada.Real_Time, it knows the types, but it's ignoring the overloading for some reason. I've just started learning Ada for this project at work, so if I'm missing something completely obvious, then I wouldn't be surprised.

Congratulations on having the first Ada question in CoC, to the best of my knowledge.

Looks like it will be the last Ada question, too.

For those 15 years from now who search this thread and maybe would like a stop-gap solution, I was able to get Ada.Real_Time."+"(Poll_Time, Period) to work. Don't ask me why the normal way doesn't work, because I have no clue.
