create directory for dir/file.o
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)
