This looks like Microsoft NMAKE. In general, MS NMAKE has a much more
expressive syntax for expressions like this, so you may have some
difficulty converting. However, in this particular case, I think the
following GNU make syntax is equivalent:
ifneq ("$(LEVEL)","1")
$(error Level is not valid!)
endif
That's not equivalent. But this would be:
ifeq (,$(filter $(LEVEL), 1 2 3))
$(error Level is not valid!)
endif
Cheers!
LOL: I should have known better than to answer before my morning
coffee, but it looks like you should have too! The original construct,
with NMAKE, accepts LEVEL with values 0, 1 and 2. My first attempt
accepted only LEVEL=1. Your attempt accepts LEVEL with values 1, 2 or 3.
The correct expression is:
ifeq (,$(filter $(LEVEL), 0 1 2))
$(error Level is not valid!)
endif
