Dear all:
I read the document about make recently.
I have some questions:
1. in example 1 list below that excerpted from document, there are 2
disadvantages:
1. Cannot see the error.
2. Cannot use parallel execution.
So the doc uses modification 1 to fix them, but if I use modification 2, I
will also fix them, right? Except I cannot force make to rerun it every
time, if there is already a file called subdirs.
Appreciate your help,
vichy
Example1:
SUBDIRS = foo bar baz
subdirs:
for dir in $(SUBDIRS); do \
$(MAKE) -C $$dir; \
done
Modification 1:
SUBDIRS = foo bar baz
.PHONY: subdirs $(SUBDIRS)
subdirs: $(SUBDIRS)
$(SUBDIRS):
$(MAKE) -C $@
foo: baz
modification 2:
SUBDIRS = foo bar baz
.PHONY: $(SUBDIRS)
subdirs: $(SUBDIRS)
$(SUBDIRS):
$(MAKE) -C $@
foo: baz
