Consider such makefile:
first: second
@echo 1
@echo $(error xxx)
second:
@echo 2
When invoke
$ make first
2
makefile:2: *** xxx. Останов.
I think this behavior is nice because allow implement such pattern:
target: dep1 ... depn
recipe
ifeq '$(WEBTOOL)' 'wget'
wget ....
endif
ifeq '$(WEBTOOL)' 'curl'
$(error Not implemented) ## THIS IS NICE!
endif
I think this must be true:
1) target recipes expanded only when target executed and all before any
shell command
execution
2) if in variable/function expansion happen $(error ...) then make stops
I read manual and don't find explicit description about this.
