I think he was implying something like this:


MODULE_LIST:=one two three

.PHONY: all
all:
        @echo $(MODULE_LIST)

define clean_module
.PHONY: clean_$(1)
clean_$(1):
        @echo "Clean: $(1)"
CLEAN_EXTRA+= clean_$(1)
endef

$(foreach MODULE,$(MODULE_LIST),$(eval $(call clean_module,$(MODULE))))

.PHONY: clean
clean: $(CLEAN_EXTRA)
        @echo "Clean: main"
