Maybe this:

info make
-> Writing rules -> Directory  search




OK, thanks, that will help me search thru a big Info file.  Books  aren't 
much help.

It occurred to me to try porting the Tim Kientzle OS9 Make to Linux --  would 
work, *if* the source includes the Unix calls for getting a file's  timestamp.

As far as generating products, that has more to do with the  compiler
than make, right?
Where the compiler generates .o files is  controlled by compiler options.




Partly correct -- probably do have to put something in CFLAGS to steer the  
output.  And some more flags to make the Linker pick up the .o files from  the 
right place.
But, Make has to know where to look for the .o files, to see which are out  
of date.
 
In Tim K.'s Make (which I helped work on, and fixed the Y2K bug in), it was  
sooooo simple!
Of course, "simple" is never used around Linux/Unix work :-)
