Compiling Ada with GCC in Ubuntu

One of my students wanted to to compile Ada  on Ubuntu for a project he is working with. He came to me for help. But Ada is like Chinese to me. How ever I  managed to compile a simple hello world program. as below on Ubuntu 9.04

1. Install GNAT (GNU New York University Ada Translator):

sudo apt-get install gnat

2. Here is the hello.adb

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

3. And use this command to compile:

gnat make hello.adb

You will get hello.ali and a binary hello in your home directory.

Alternately you can split the steps

1. Run gcc to compile to object file:

gcc -c hello.adb

2. Run gnatbind to produce binder output:

gnatbind hello.ali

3. Run gnatlink to link and produce executable output:

gnatlink hello
