Hi,

This has been reported by a debian user.
Package: make
Version: 3.80-4
I have always thought that a normal (non-pattern) rule with multiple
targets gets run multiple times, once per each target that is out of
date. At least, that's what the manual says. Sometimes one would
like a different behavior, namely to update all the targets at once
with one run, but as long as it's documented and established I am
willing to live with it. But there seems to be more to it.
MODULES := \
Blah \
Bleh \
SOURCES := $(addsuffix .sml,$(MODULES))
TEX := $(addsuffix .tex,$(MODULES))
modules.tex : $(TEX)
cat $(TEX) > modules.tex
$(TEX) : $(SOURCES)
./bin/plit $(SOURCES)
I have files Blah.sml and Bleh.sml.
Surprise #1: make modules.tex runs the last rule _once_ (which happens
to be what I want in this case).
Surprise #2: add a flag to the command, so now the last rule is
$(TEX) : $(SOURCES)
./bin/plit -n $(SOURCES)
touch one of the .sml files, make modules.tex again. Now plit runs twice!
Surprise #3: refactor like this
$(TEX) : junk
junk: $(SOURCES)
./bin/plit -n $(SOURCES)
touch Blah.sml. Now make modules.tex runs the last rule (once), but
not the first rule (for modules.tex itself), even though it clearly is
out of date!
