Is there an option less verbose than --debug that outputs which
dependencies triggered a target action?
You can hack it like this:
OLD_SHELL := $(SHELL)
SHELL = $(warning Building $@ $(if $?,because $? newer,because $@
is missing))$(OLD_SHELL)
Then you'll get a lot of warnings. If you filter on just those that
mention a Makefile name and line number you'll see something like this:
shell3.mak:8: Building foo because foo is missing
shell3.mak:8: Building bar because bar is missing
shell3.mak:5: Building all because foo bar newer
for a Makefile like that:
all: foo bar
@echo Make all
foo bar:
@echo Make $@
I am planning to write an article for CM Crossroads about tricks with
redefining SHELL for the October CM Basics.
