I cannot get the package Ada.Execution_Time to work with gnat,
although the gnat documentation says that the real-time annex is fully
supported... I use the gnat version 4.4 on a Ubuntu 9.10 distribution.
The typical error message I get is
gcc -c executiontime.adb
Execution_Time is not supported in this configuration
compilation abandoned
How can I configure gnat to support the Ada.Execution_Time package?
Hopefully somebody can help me!
Thanks in advance!
Ingo
Below follows an example program that generates the error messge.
with Ada.Text_IO; use Ada.Text_IO;
with Ada.Real_Time; use Ada.Real_Time;
with Ada.Execution_Time;
procedure ExecutionTime is
task T;
task body T is
Start : CPU_Time;
Interval : Time_Span := Milliseconds(100);
begin
Start := Ada.Execution_Time.Clock;
loop
Put_Line(Duration'Image(Ada.Execution_Time.Clock - Start));
delay To_Duration(Interval);
end loop;
end T;
begin
null;
end ExecutionTime;
