Right. What used to be there was something like net-obj-y = foo.o bar.o common-obj-y += $(addprefix net/, $(net-obj-y)) and this has been replaced by net/Makefile.objs and friends. This should not be undone, but it is completely different from what you are trying to do. You need a much more fine-grained assignment of libraries to object files. I think the build system parts are hard because we haven't found the right design. > So, are you saying we should abandom this whole idea?
