Others have given you good advice, but the short and sweet answer is: if
you use the method for automatic dependency generation described in the
GNU make manual, you CANNOT generate both the dependency file and the
object file (true compilation) with the same rule.

In order for the method in the book to work correctly you MUST have a
separate step that generates only the dependency information and does
not generate an object file.


If you want to learn about a more advanced method than the one found in
the GNU make manual, that does allow the dependency generation and
compilation steps to be the same, see my web page below.
