$(call if_changed,link-vmlinux)是调用函数 if_changed, link-vmlinux 是函数 if_changed 的参数,函数 if_changed 定义在文件 scripts/Kbuild.include 中,如下所示: 示例代码 35.5.3.10 scripts/Kbuild.include 代码段 247 if_changed = $(if $(strip $(any-prereq) $(arg-check)), \ 248 @set -e;...
4、文件指示。其包括了三个部分,一个是在一个Makefile中引用还有一个Makefile,就像C语言中的include一样;还有一个是指依据某些情况指定Makefile中的有效部分,就像C语言中的预编译#if一样;还有就是定义一个多行的命令。有关这一部分的内容,我会在兴许的部分中讲述。 5、凝视。Makefile中仅仅有行凝视,和UNIX的...
