Re: executing a rule prior to any targets?

Or you could put this into a variable assignment, where it won't be

  _x := $(if $(RECURSE), $(shell RECURSE=; $(MAKE) recurse ) )

This is typically how $(shell ...) would be used, otherwise the output
of the make command would be considered make syntax which should be
parsed, which is probably not what you want.

Now I understand much better.

Yes, the method you suggest above does work but the problem is that output is 'swallowed' by assignment to _x and doesn't appear in the terminal.

I would like to be have $(MAKE) recurse run just like if I had typed 'make recurse' on the command line.
I wanted to do something similar with a 'debug' rule to echo some makefile variables to the terminal; to somehow invoke the rule from the makefile, without it having to be a target.

The problem I am trying to solve is:
* I do not want to specify 'recurse' as a command line goal; I want to build $(MAKECMDGOALS) in each directory in my list:
recurse :
@for dir in $(SUBDIRS); do\
$(MAKE) -C $$dir $(MAKECMDGOALS); \
done

I could add 'recurse' as a command line goal, then remove it from $(MAKECMDGOALS) in the makefile:
GOALS = $(filter-out recurse, $(MAKECMDGOALS) )
recurse :
@for dir in $(SUBDIRS); do\
$(MAKE) -C $$dir $(GOALS); \
done

This seems a bit awkward though.
Can anyone suggest a more straight-forward way to explicitly execute a rule?
