Dear all,
I have some questions about u-boot Makefile.
Could you help me ?
Thx!
The below is my question.
First, we do make _depend for those $(SUBDIRS) $(CPUDIR)
$(LDSCRIPT_MAKEFILE_DIR)
depend dep: $(TIMESTAMP_FILE) $(VERSION_FILE) \
$(obj)include/autoconf.mk \
$(obj)include/generated/generic-asm-offsets.h \
$(obj)include/generated/asm-offsets.h
for dir in $(SUBDIRS) $(CPUDIR) $(LDSCRIPT_MAKEFILE_DIR) ;
do \
$(MAKE) -C $$dir _depend ; done
after we already generated the .depend file in those dirs.
$(SUBDIRS): depend
$(MAKE) -C $@ all
That would do make action in SUBDIRS dir.
But why we also sinclude .depend in those Makefile which is base on
those dir ? I regard that we already generated before.
And another questions, how does the other sub-dir(eg, libs) .depend
file generated ? is that generated by rules.mk which is include every
sub-dirs?
Best regards
