_______________________________________________________
Details:
See the following makefile:
=======
export EXVAR = exval
_temp := $(shell echo "EXVAR = $${EXVAR}, CMDVAR = $${CMDVAR}" 1>&2)
all:
=======
``make CMDVAR=cmdval'' currently outputs:
-------
EXVAR = , CMDVAR =
make: `all' is up to date.
-------
But in some situation, the following output is expected:
-------
EXVAR = exval, CMDVAR = cmdval
make: `all' is up to date.
-------
I encountered this problem when I was working on my GnumakeUniproc project in
the past year(http://sf.net/projects/gnumakeuniproc), and I have to find a
workaround for it -- unfortunately.
I hope GNUmake's next version gives a option to enable my suggested
behavior.
By the way, an anonymous person has posted such issue two years ago.
