I looked at make Changelog, time ago, and this feature was added in make 3.80, so you'd need to update Documentation/Changes. Make 3.80 was released in 2002-10-03, so I hope it's not a problem (should check on Debian Woody though, maybe). > I'm using > it to generate and process > > bar-y := ../../$(SUBARCH)/foo/bar.o > ... > for all HOST_OBJS elements. If there are better suggestions, I'd be glad > to hear them... The first thing is that HOST_OBJS is totally confusing... SUBARCH_OBJS or something else is better. The second is that, even if x86_64 uses things such as (from arch/x86_64/mm/Makefile): obj-$(CONFIG_HUGETLB_PAGE) += hugetlbpage.o hugetlbpage-y = ../../i386/mm/hugetlbpage.o (because hugetlbpage.o is conditional) we could as well do subarch-y := ../../$(SUBARCH)/name (even with foreach) for most things (see arch/x86_64/oprofile/Makefile), and for highmem and module I'd just do that by hand: highmem-y := $(SUBARCH_DIR)/mm/highmem.o module-y := $(SUBARCH_DIR)/kernel/module.o with SUBARCH_DIR defined in arch/um/Makefile. -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
