RE: auto-dep cannot possibly work?

If you mv a file, all files which included the old name must be edited, and therefore also rebuilt.

No, no, it is not foobar.h that is moved.  include/foobar.h is included.  We would prepare a new header file, long time ago, with the name include1/foo.h.  And now we

 

>mv include1/foo.h include1/foobar.h

 

 

No files have to be changed at all.  All files just

#include “foobar.h”

 

It is only the path of the found foobar.h, that changes. 

 

 

 

But as I said, the developers must be aware, that “mv” does not change timestamp, and that timestampts are important with make.  They know this, whether is a complex or simple makefile without dependencies.
