Re: Limiting expansion of make variables

[Richard Cavell]

   Prepending a backslash simply prints the backslash on my machine (bash
   3.2.48, make 3.81, I'm on an old machine).  It seems to make no
   difference to make whether I use single or double quotes.  This works
   for me:

   dumpvars: foo.o bar.o foobar
       @echo '$$(RM) is :' $(RM)
       @echo "$$^ is :" $^

   (Just doubling the $ sign).

   Actually, use \$$. Double the dollar sign to escape it for make.
   Prepend the slash (or put it in single quotes) to keep the shell from
   expanding it.

        Hello all.  For debugging purposes, I am trying to put this into
     my
        makefile:
        .PHONY: dumpvars
        dumpvars: source.c source.h
        @echo "$(RM) is " $(RM)
        @echo "$? expands to : " $?
        and so on.  But obviously, Make is expanding all instances of the
        variables' names.  How do I prevent this?
        TIA,
