Hi,
Suppose there are many subdirectories in a directory. The sub dirs all
have working makefiles.
'make -j3' in the parent dir would parallel make all directories. But
'make clean -j3' could not. The problem is that I don't know how to
clean each directory as well as deleting the file '.d'.
Can somebody let me know how to do it?
Thanks,
Peng

.PHONY: all clean
SUBDIRS := $(filter-out backup bash doc,$(patsubst %/.,%,$(wildcard */.)))
.PHONY: $(SUBDIRS)
all: $(SUBDIRS)
-include .d
.d:
@rm -f $@; \
for dir in $(SUBDIRS); do \
echo $$dir: >> $@; \
echo -e "\t"@$$\{MAKE\} -C $$dir $$\{MAKECMDGOALS\}>> $@; \
echo >> $@; \
done
clean:
@$(RM) .d; for dir in $(SUBDIRS); do \
$(MAKE) -C $$dir clean & \
done
