Make is not designed to be an interactive tool; it's designed and
intended to be non-interactive. So, no, I don't know of any
fundamentally better way to do what you're asking (although if it were
me I wouldn't bother with creating shell scripts, etc. and I'd just
do it something like this:
QUERYUSER = $(shell echo "$1" 1>&2; read input; echo $$input)
VALUE1 := $(call QUERYUSER, Enter value 1:)
VALUE2 := $(call QUERYUSER, Enter value 2:)
This does write the prompt to stderr instead of stdout, but...
But, if it _really_ were up to me I wouldn't use interactivity at all.
I'd check if the variables were set and if not I'd just fail, and have
people set them on the command line:
ifndef VALUE1
$(error Please set the VALUE1 variable.")
endif
ifndef VALUE2
$(error Please set the VALUE2 variable.")
endif
