Re: ede cedet does not compile .elc

Hi,

When changing Make project to Automake it works. But it
produces a much more complicated Makefile that is not
necessarily useful for simple lisp projects.


When manually removing the phony target from the Makefile
produced by the Make type project it works as well. Maybe is my
knowledge of Makefile not sufficient to understand why there is
this phony target but anyway I suspect that it can safely be
removed ! In previous versions there was only the phony target
and not the implicit rule %.elc: %.el. Are these two thing not
compitible for any reason that I do not really understand ?

Maybe I should say that make is 3.82.

Regards

Pierre
