[Note] Ada on Ubuntu 20

Installing Ada


Apt has two packages.  GNAT-GPS (IDE) didn't work properly for me:
  • gnat-gps - integrated development environment for C and Ada
  • gnat - GNU Ada compiler

Get this file from here and install instead -- it will install everything in one directory:

Compiling in console

$ vi helloworld.adb

with Ada.Text_IO;
procedure Hello is
begin
    Ada.Text_IO.Put_Line("Hello, world!");
end Hello;

$ gnatmake helloworld.adb
$ ll
