Eval

[Mike Gibson]

I'm trying to use eval to create rules automatically and I use foreach to 
generate a bunch of rules:

define make_rule
$(1) : $(1).a
        command $(1).a
endef

LIST := foo bar joe jane

$(foreach value,$(LIST),$(eval $(call make_rule,$(value))))

Which works.  If I then try to split the foreach line like this:

$(foreach value,$(LIST),\
$(eval $(call make_rule,$(value))))

I get:

Makefile:30: *** missing separator.  Stop.

Could someone please explain this?
