Ok what you are looking for is making depends for each file. You can do
this the hard way and that is each time you add a file you add all the files
that it depends on. That or you can run gcc and make it create the depends
for you. I could write a long mail on how to do this but it might be better
to read the Makefile manual for this now that you have a little experience
with make files. Note these depends are one reason I go with jamfiles when
I can because you never have to worry about them with them but that is
another bear in the woods. Ok here is the web page for the make file
manual:
http://www.gnu.org/software/make/manual/make.html
Two other things to search for on Google would be makedepends which is a
command to auto create depends or if you look through Gcc's options you will
find an option to create depends I can't remember if it is mm or Mm or what
but if you search the man pages you can find them. I still suggest though
if you have made a few simple Makefile read the Make manual and see what you
know and don't.

Subject: a way around make clean;make?
hello all,
I have a quick question: when I run my makefile, I want it to check to see
what files were modified and then work based off of that modification. So,
for example. If I modify file 2 and 8, I want it to recompile 2.cpp and
8.cpp and link. Right now, i have to make clean, then make for the new
changes, or just delete the object files myself. Does anyone have a
workaround? It'd be really helpful.
Thanks,
Tyler Littlefield
