Follow-up Comment #6, bug #57676 (project make): > I would consider this a bug in make Well, it's not wrong that there is no rule to make the dependency file and adding one does silence it (this is make-4.3.90):
martind@paris:~/tmp/make-57676$ cat Makefile2 -include deps BADGER := $(shell touch deps) some-file: deps; deps:; martind@paris:~/tmp/make-57676$ rm -f deps; make -f Makefile2 make: 'some-file' is up to date. martind@paris:~/tmp/make-57676$ https://www.gnu.org/software/make/manual/html_node/Include.html doesn't just say the leading hyphen suppresses errors when the file doesn't exist, but also says that it suppresses errors when it cannot be remade. Indeed, this is silent: martind@paris:~/tmp/make-57676$ cat Makefile3 -include deps some-file:; martind@paris:~/tmp/make-57676$ So the issue only arises when the -include()d file is also a dependency. It's not just that there's no rule to make that dependency, because Make does notice that it's appeared in: martind@paris:~/tmp/make-57676$ cat Makefile4 BADGER := $(shell touch deps) some-file: deps; martind@paris:~/tmp/make-57676$ rm -f deps; make -f Makefile4 make: 'some-file' is up to date. martind@paris:~/tmp/make-57676$ If the side-effect happens before the -include, then all is also well: martind@paris:~/tmp/make-57676$ cat Makefile5 BADGER := $(shell touch deps) -include deps some-file: deps; martind@paris:~/tmp/make-57676$ rm -f deps; make -f Makefile5 make: 'some-file' is up to date. martind@paris:~/tmp/make-57676$ Putting all that together, the new behavior does feel... unfortunate, at least to me. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?57676> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
