RE: Is -C @ magical?

[Doug Konrad]

FWIW, this is problem is caused by infinite recursion. The first invocation in 
the OBJDIR has the correct path to the Makefile, since it was invoked from the 
source directory and CURDIR points to the source. But when the make command is 
invoked a second time, from OBJDIR, CURDIR points to OBJDIR as it should.

Paul,

This has become a moot problem for me - when I came across this, I was trying 
to work around another problem, which I have fixed. Thanks for your attention 
to this.

Paul,

I missed one of your questions - the embedded space in the error message was 
accidently added by me when obscuring the path.

Paul,

I changed the path to ``/.../some/other/path`` to obscure details I shouldn't 
publicize.

I did make one change - I removed a $(TOP). Here is a more accurate 
representation:

MAKETARGET = $(MAKE) --no-print-directory -C $(TOP)/.../some/other/path -f 
$(CURDIR)/Makefile \
                 SRCDIR=$(CURDIR) $(MAKECMDGOALS)

I placed an echo of $(TOP)/.../some/other/path immediately prior to the 
invocation of MAKETARGET and that path matched the path in the error message 
exactly. $(TOP) contains only ``/home/vmuser/Work/software-internal`` .

Is the error message above verbatim, including the embedded space in the 
pathname after "path" and before "/Makefile"?

That's ultra-bizarre.  Can you provide a reproducible case (cut down)?
You're really just replacing the $@ with a simple explicit path exactly as you 
show above?  No quoting, make variables, etc.?

Can you also paste the recursive make command that make is invoking?
You might have to remove the "@" so it will be printed.  That should definitely 
be illuminating.
