Can anyone explain to me why running GNU Make 3.80 on the following
makefile:
THINGS := one two three
define THING_template
ALL += `date +%s; sleep 1`
THIS = $(shell date +%s; sleep 1)
ALL2 += $(THIS)
endef
$(foreach thing,$(THINGS),$(eval $(call THING_template,$(thing))))
debug:
@echo ALL = $(ALL)
@echo ALL2 = $(ALL2)
...results in the following output:
$ make
ALL = 1091577190 1091577191 1091577192
ALL2 = 1091577187 1091577188
I would have expected something more like this:
$ make
ALL = 1091577190 1091577191 1091577192
ALL2 = 1091577186 1091577187 1091577188
Where did the other append to ALL2 go?
Thanks,
Dave
