Re: Help in Updating Multiple Targets

[Mike Gibson]

I don't quite get what you assignment is, but I get the impression that you're 
trying to create rules based on the contents of a flat file.  You could use 
$(eval ...) and $(shell ...) to do this.  Like, say you've got a comma 
delimited flat file of targets in the first column, prereqs in the second, 
and rules in the third, you could do something like this to get it into your 
makefile

----------
define parse_flatfile
$(shell awk -F "," -f $(1) -- '{print $$1" : "$$2"\n\t"$$3}')
endef

$(eval $(call parse_flatfile,flatfilename.txt))
----------

I didn't test this, so take it for what it's worth.
