building a smiple hello_world

[Fred J.]

Hello
I am learning the GNU build system and need some help.

I constructed an simple program but not sure if there
is something wrong.
$automake gives this error
configure.ac:7: required file `./ltmain.sh' not found

questions:
--why the error above and how to fix?

--do I need to include the following in every scource
file in the tree?
#ifdef HAVE_CONFIG_H
#include <config.h>
#endif

I use the run file to save typing, any problem with
using it with ever project I create?

many thanks
