How can I design an ada library that other ada programs can include
and how do I include the library in the other ada files?

Thanks,

This depends on your compiler and host operating system.  If you are
more specific, then someone can give you a "recipe".

Generally speaking, you write your library as a set of Ada packages,
separating specifications from bodies, and you compile all these
bodies into a library.  You then provide the specifications for use by
the programs.  Some compilers require that you also provide the bodies
for generic units.

An example (with GNAT you need to make 3 files out of it: lib_1.ads,
lib_2.ads, my_prog.adb) :

-- A standalone library
package Lib_1 is
  hello: String:= "Hello from library 1 !";
end;

-- Library 2 is using Library 1
with Lib_1;
package Lib_2 is
  hello: String:= Lib_1.hello;
end;

-- An application using Library 2 (and indirectly Library 1)
with Lib_2, Ada.Text_IO;
procedure My_prog is
begin
  Ada.Text_IO.Put(Lib_2.hello);
end;
