  "message": "kbuild: create directory for dir/file.o\n\nWhen add a obj with dir to obj-y, like this\n\n    obj-y +\u003d dir/file.o\n\nThe $(obj)/dir not created, this patch fix this.\n\nWhen try to add a file(which in a subdir) to my board\u0027s obj-y, the build\nprogress crashed.\n\nFor example, I use at91rm9200ek board, and in kernel dir run:\n\n  mkdir objtree\n  make O\u003dobjtree at91rm9200_defconfig\n  mkdir arch/arm/mach-at91/dir\n  touch arch/arm/mach-at91/dir/file.c\n\nand edit arch/arm/mach-at91/dir/file.c to add some code.\nthen edit arch/arm/mach-at91/Makefile, change the following line:\n\n  obj-$(CONFIG_MACH_AT91RM9200EK) +\u003d board-rm9200ek.o\n\nto:\n\n  obj-$(CONFIG_MACH_AT91RM9200EK) +\u003d board-rm9200ek.o dir/file.o\n\nNow build it:\n\n  make O\u003dobjtree\n\nThen the error appears:\n  ...\n  CC      arch/arm/mach-at91/board-rm9200dk.o\n  CC      arch/arm/mach-at91/board-rm9200ek.o\n  CC      arch/arm/mach-at91/dir/file.o\n  linux-2.6/arch/arm/mach-at91/dir/file.c:5:\n    fatal error: opening dependency file\n    arch/arm/mach-at91/dir/.file.o.d: No such file or directory\n\nCheck the objtree:\n  LANG\u003den ls objtree/arch/arm/mach-at91/dir\n  ls: cannot access objtree/arch/arm/mach-at91/dir: No such file or directory\n\nIt\u0027s apparently that the target dir not created for file.o\n\nCheck kbuild source code. It seems that kbuild create dirs for that in\n$(obj-dirs).  But if the dir need not to create a built-in.o, It should\nnever in  $(obj-dirs).\n\nSo I make this patch to make sure It in  $(obj-dirs)\n\nthis bug caused by commit\n   f5fb976520a53f45f8bbf2e851f16b3b5558d485\n\nSigned-off-by: 张忠山 \u003czzs0213@gmail.com\u003e\nSigned-off-by: Michal Marek \u003cmmarek@suse.cz\u003e\n",
