从源代码编译内核。错误解释。

Question

我正在从源代码编译 android 内核。但是在制作对象 tspdrv.o 时遇到了一些错误，无法弄清楚它是从哪里生成的。以下是错误:

我需要了解此错误的根源，因为它不会将我带到任何地方。例如让这部分错误

drivers/tspdrv/ImmVibeSPI.c: In function 'drv2604_write_reg_val':
include/linux/dynamic_debug.h:61:16: error: implicit declaration of 
function 'KBUILD_STR' [-Werror=implicit-function-declaration]

         ^

include/linux/dynamic_debug.h:61:16

中没有名为 KBUILD_STR 的函数

还是我读错了？

Answer 1

看起来 KBUILD_STR 已从 4.2 和 4.10 之间的某个位置的内核构建脚本中删除。

看起来驱动程序尚未更新以匹配。
