My OP:
I have the following make file:
-------------------------------------------
all: something else
.PHONY: MakeAppleJuice MakeOrangeJuice MakeTomatoJuice
MakeAppleJuice:
make_juice Apple.in.source Apple.in.condition
MakeOrangeJuice:
make_juice Orange.in.source Orange.in.condition
MakeTomatoJuice:
make_juice Tomato.in.source Tomato.in.condition
-------------------------------------------
Is there anyway to combine the 3 rules into one? I hope there is, because
the 3 rules only different in what files they use and what juices then make
(but I still need the 3 phony targets).

I just tried "Empty Target Files" trick,
http://www.gnu.org/software/autoconf/manual/make/Empty-Targets.html#Empty-Targets
-----------------------------------------------------------
$ cat Makefile
make_juice := echo
all: something else
MakeJuice: $(wildcard *.in.source)
$(make_juice) $? $(addsuffix .in.condition, $(patsubst
%.in.source,%,$?))
touch MakeJuice
$ make MakeJuice
echo Orange.in.source Tomato.in.source Orange.in.condition Tomato.in.condition
Orange.in.source Tomato.in.source Orange.in.condition Tomato.in.condition
touch MakeJuice
$ make MakeJuice
make: `MakeJuice' is up to date.
-----------------------------------------------------------
But that's different than my OP, because I need to deal with each juice
explicitly, and the command format is strictly
make_juice $*.in.source $*.in.condition
So, is it possible to have such generic phony rule?
Thanks
