But it's for interfacing with other languages, isn't it?
The point is I don't want to interface with some other language, I want 
to create Shared object in Ada and then link with this shared object

So you mean that if I use the pragma export in my ads file, everything 
is going to be fine?

For instance:
function My_Ada_Function return Integer is begin
   return 1;
end My_Ada_Function;
pragma Export
(Convention    => C,
  Entity        => My_Ada_Function,
  External_Name => "My_Ada_Function" );

Or will I have to get two ads file? One with the pragma Export to create 
the shared object, and then one with the Pragma import to use the shared 
object in my program?

Yes I think I can find out by myself especially because I'm using gnat ;-)
