Hi.
I have two similar Makefiles.
[Makefile1]
.PHONY: all
all: foo.p foo.q
foo.p foo.q &: foo.r FORCE
@echo \$$? = $?
touch foo.p ; touch foo.q
.PHONY: FORCE
[Makefile2]
.PHONY: all
all: foo.p foo.q
%.p %.q : %.r FORCE
@echo \$$? = $?
touch foo.p ; touch foo.q
.PHONY: FORCE
The two Makefiles are the same, except for one line.
Makefile1 uses grouped targets.
Makefile2 uses a pattern rule with multiple targets.
My hope is that those two work in the same way.
[test Makefile1]
$ rm -f foo.*
$ touch foo.r
$ touch foo.p
$ make -f Makefile1
$? = foo.r FORCE
touch foo.p ; touch foo.q
[test Makefile2]
$ rm -f foo.*
$ touch foo.r
$ touch foo.p
$ make -f Makefile2
$? = FORCE
touch foo.p ; touch foo.q
The value of $? is different.
I just thought this was fixed by
commit fabb03eac412b5ea19f1a97be31dc8c6fa7fc047
In my opinion, the behavior of Makefile1 is preferred.
Is the behavior of Makefile2 expected?
