This is not really a bug report, more a cry for help.

I'm trying to create a gnu makefile that has several recursive targets.
The classic example would be a clean-all, which should clean the current
directory and any subdirectories.  My target in my makefile looks like
this:

clean-all depend-all lint-all: $(patsubst %-all,%, $@)
	ifneq "$(SUBDIRS)" ""
	-(for i in $(SUBDIRS) ; do\
		$(MAKE) -C $$i  $@; done)
	endif

where SUBDIRS is a list of directories.

What I am trying to get here is that if I do a make clean-all, the
clean-all target depends upon a target clean, then it does a clean-all
in every subdirectory.  What I get is a dependency that is basically
NULL.  It never executes the clean (or depend or lint), but does execute
the rest of the rule.

Any ideas about how to get this to work?

BTW, I realize that I could just create separate targets for each of
these, repeating the code under each target.  For now, I guess that is
what I will do.

I have the answer (thanks Roland), the target line should be:

clean-all depend-all lint-all: %-all: %

and, this is in the manual, I just missed it.

Thanks,
