You need to provide a "procedure Main" in a file called "main.adb". It 
is possible to override the naming convention - but this is an advanced 
topic.

Other poster told you not to use project files - but you should not take 
our word for it so here a set working project files for "hello world.":

http://svn.sourceforge.net/viewvc/wikibook-ada/trunk/demos/GNAT/hello_world.gpr?view=markup
http://svn.sourceforge.net/viewvc/wikibook-ada/trunk/demos/GNAT/wikibook_ada.gpr?view=markup

As it is usual in larger project he project files are split into to: A 
general part and a specialized part. You can also see that project files 
are quite powerful and quite an advanced topic.

In C talk: Ada uses pre-compiled header files *only* and they are not 
"#include"-ed but "with"-ed.
