This rule is not what you want. Multiple targets is identical to
writing the same rule multiple times, it does _NOT_ mean that running
that command once will create all the targets. In other words, the
above command is identical to this:
foo.h: bar.h junk.h sth.h bar.o junk.o sth.o
command-to-build-packet foo
foo.o: bar.h junk.h sth.h bar.o junk.o sth.o
command-to-build-packet foo
That's not what you want: you want to tell make that it only needs to
run the rule once to build both targets. You do that with a
multi-target pattern rule, like this:
%.h %.o: %
command-to-build-packet $*
(I don't know what the dependency should be: your rules don't seem to
show what the command builds the packet _from_), then this:
foo.h foo.o: bar.h junk.h sth.h bar.o junk.o sth.o
(with no command script).
