看起来你没有内核头文件。 这些定义在linux / capability.h中定义，看起来像： #define _LINUX_CAPABILITY_VERSION_1 0x19980330 #define _LINUX_CAPABILITY_U32S_1 1 #define _LINUX_CAPABILITY_VERSION_2 0x20071026 / *已弃用 - 使用v3 * / #define _LINUX_CAPABILITY_U32S_2 2 #define _LINUX_CAPABILITY_VERSION_3 0x20080522 #define _LINUX_CAPABILITY_U32S_3 2 如果您没有内核头文件，可以使用“make menuconfig”禁用“Support capabilities”，错误将消失。
