I can't justify to myself why this makefile
define something
ifneq (,)
$(warning weird)
endif
endef
$(call something)
generates the following output
testcase.mk:6: weird
testcase.mk:6: *** missing separator. Stop.
What I'm trying to do is rudimentary checking of the parameters passed
to a function. I know that the function I am writing should take two
parameters so I'm checking to see if $(3) is empty or nonempty. If it
is nonempty, I want to end processing with $(error). What is the idiomatic
way of doing this?
