gnatmake on Ubuntu

.gitignore

hello
hello.ali
hello.o

README.md

See http://stackoverflow.com/questions/13298113/gnatlink-fails-under-new-ubuntu-version

Files:

• hello.adb, a simple Ada hello world program (the \n is my little joke)
• log.txt, output showing that gnatmake works (at least for me)

(I removed some excess whitespace from log.txt.)

See if you're missing some packages.

hello.adb

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