顶层Makefile分析

执行 make时，第一个shell命令：

  CHK include/linux/version.h

以此为线索跟踪Makefile目标流程。

 

include/linux/version.h:$(srctree)/Makefile FORCE

prepare1:prepare2 include/linux/version.h include/asm \

                  include/config/MARKER

archprepare: prepare1

prepare0: archprepare FORCE

prepare prepare-all: prepare0

$(vmlinux-dirs): prepare scripts

vmlinux: $(vmlinux-lds) $(vmlinux-init) $(vmlinux-main) $(kallsyms.o) FORCE

all: vmlinux

_all:

_all:all
