-include $(pathsubst %.o=%.d,$(all-objs)) ? With a requiriment that all actually compiled objects be listed in $(all-objs) somehow, either by adding them to one of the common $(obj-y) or $(common-obj-m), or explicitly adding them to $(all-objs) if it is used in some custom way. Also, it can be done even funnier, something like this: subdirs = custom_subdir1 custom_subdir2 subdirs := $(sort $(subdirs) $(dirname $(objs))) -include *.d $(pathsubst %=%/*.d,$(dirs)) or just list all subdirs explicitly in $(subdirs). There's nothing fancy in there really. Thanks, /mjt
