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，并且无法确定它的生成位置。以下是错误：

我需要了解这个错误的根源，因为它不会引导我到任何地方。例如，让我们把这部分错误

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]
  static struct _ddebug __aligned(8)          \
         ^

KBUILD_STR

中没有名为include/linux/dynamic_debug.h:61:16的功能

或者我读错了？

Answer 1

看起来KBUILD_STR已从4.2和4.10之间的内核构建脚本中删除。

看起来驱动程序尚未更新以匹配。

从源代码编译内核。错误解释。
