How to do basic debugging with Ada?

[John Smith <yoursurrogategod@gmail.com>]

Hello,

All the way in the bottom is a simple hello world application. I compile it using gnatmake hello_world.  However, when I load it in gdb and try to set a breakpoint on the first output line, I get a message saying that the symbol table is not loaded.  If I'm missing a step, what is it?




with Ada.Text_IO; use Ada.Text_IO;

procedure hello_world3 is
begin
  Put_Line("Hello, world!");
  New_Line;
  Put_Line("I am an Ada program with package use.");
end hello_world3;
