kbuild: create directory for dir/file.o
When add a obj with dir to obj-y, like this obj-y += dir/file.o The $(obj)/dir not created, this patch fix this. When try to add a file(which in a subdir) to my board's obj-y, the build progress crashed. For example, I use at91rm9200ek board, and in kernel dir run: mkdir objtree make O=objtree at91rm9200_defconfig mkdir arch/arm/mach-at91/dir touch arch/arm/mach-at91/dir/file.c and edit arch/arm/mach-at91/dir/file.c to add some code. then edit arch/arm/mach-at91/Makefile, change the following line: obj-$(CONFIG_MACH_AT91RM9200EK) += board-rm9200ek.o to: obj-$(CONFIG_MACH_AT91RM9200EK) += board-rm9200ek.o dir/file.o Now build it: make O=objtree Then the error appears: ... CC arch/arm/mach-at91/board-rm9200dk.o CC arch/arm/mach-at91/board-rm9200ek.o CC arch/arm/mach-at91/dir/file.o linux-2.6/arch/arm/mach-at91/dir/file.c:5: fatal error: opening dependency file arch/arm/mach-at91/dir/.file.o.d: No such file or directory Check the objtree: LANG=en ls objtree/arch/arm/mach-at91/dir ls: cannot access objtree/arch/arm/mach-at91/dir: No such file or directory It's apparently that the target dir not created for file.o Check kbuild source code. It seems that kbuild create dirs for that in $(obj-dirs). But if the dir need not to create a built-in.o, It should never in $(obj-dirs). So I make this patch to make sure It in $(obj-dirs) this bug caused by commit f5fb976520a53f45f8bbf2e851f16b3b5558d485 Signed-off-by: 张忠山 <zzs0213@gmail.com> Signed-off-by: Michal Marek <mmarek@suse.cz>
