Hi!
I am using make v4.3.
I have a Makefile I always want rebuilt, and included.
include test.mk
.PHONY: all
all:
@echo MAKE_RESTARTS: $(MAKE_RESTARTS)
.PHONY: test.mk
test.mk:
touch $@
this results in:
make --debug

touch test.mk
Updating goal targets....
File 'all' does not exist.
Must remake target 'all'.
MAKE_RESTARTS:
Successfully remade target file 'all'.
note how test.mk is generated but MAKE_RESTARTS is not set.
Using the FORCE approach documented here:
https://www.gnu.org/software/make/manual/html_node/Force-Targets.html
include test.mk
.PHONY: all
all:
@echo MAKE_RESTARTS: $(MAKE_RESTARTS)
FORCE:
test.mk: FORCE
touch $@
results in somewhat expected behavior. test.mk is generated and MAKE_RESTARTS
is set. sometimes Make restarts more than one time, which is unexpected.
