Inspired by your hints, this approach ( no include file, but should allow
dynamic macro definition ) is looking promising:
$ cat makefile
$(shell echo -e 'frob=x\ngrok=y\njam=z' > /tmp/zat)
$(foreach v,$(shell set -- $$(wc -l /tmp/zat); seq $$1),$(eval $(shell sed
-ne $(v)p /tmp/zat)))
$(shell rm /tmp/zat)
.PHONEY: bar
bar:
@echo frob: $(frob)
@echo grok: $(grok)
@echo jam: $(jam)
$ rm -f /tmp/zat; make bar
frob: x
grok: y
jam: z
$ ls /tmp/zat
ls: /tmp/zat: No such file or directory
$
I need to see if I can adjust above to use mktemp instead of a constant
'/tmp/zat'
temp filename.
