RE: Must be very simple

[PATTON, BILLY \(SBCSI\)]

Let me back up  and explain more
My top level makefile contains 8 flows.  All flows depend on the
variables, which are lists, in the make.include files.  From the TOP_DIR
there exists the possibility of 5 layers of directories.  There are over
450 different directories created.  In each directory there is the
possibility of a make.include and a make.dependencies.  These files are
also stored in a Version Control System(VCS).  The hierarchail targets
depends on these variables/list to create the rules.  It's all very
hierarchial to separate all the directories. Having the list there
allows the developer of their piece the freedom to add items to any
list.  When I put all these lists into a single file it was over 25K+
lines, not very good for developers. The developer needs the option of
having not to edit the VCS version every time they need to test their
fixes.   So the top level make file needs to include the ones from the
developer area, if they exist, or from the VCS area if they don't.

Over 450 + directories -I would be too large.

I'm working on a rule

all : inc_makefiles

.NONPARALLEL : inc_makefile

inc_makefile :
<tab>$(foreach ...

But this will not work.

I must have these variables alive for the creation of rules before any
rules fire.

wildcard will work if I know if the first directory exists.  If it
doesn't I don't want to wildcard the second directory
I could K's of duplicate variables.

See my info about $(wildcard ...).

Of course, the normal way to do this is invoke make with -I:

    make -I $(SRC_TREE) -I $(OTHER_DIR) ...

then just use:

    include make.include

and make will walk the list of -I directories and include the first
"make.include" it finds.
