linux3.13.0内核编译驱动的问题

[周靖峰]

我想要在linux3.13.0上编译一个驱动

我先写好源文件，再写好makefile，但是编译的时候出现

  ERROR: Kernel configuration is invalid.
         include/generated/autoconf.h or include/config/auto.conf are missing.
         Run 'make oldconfig && make prepare' on kernel src to fix it.


  WARNING: Symbol version dump /home/zjf/zjf/kernel/linux-source-3.13.0/Module.symvers
           is missing; modules will have no dependencies and modversions.

然后我去内核目录执行了make menuconfig和make prepare
但是在执行make prepare的时候却报错了，错误提示如下：

请问这是什么错误？应该如何解决这个错误？

首先应该检查一下是否是你驱动模块的问题，即不添加这个驱动模块是否能够正常编译，所谓的“make oldconfig”等仅仅类似于“按照上一次正常的操作，进行这次操作”，在之前已经报错缺少自动配置文件，所以你在执行此命令也照样会报错。 1.如果是本来编译就缺少autoconf.h\auto.conf的话，建议你去网上这个内核版本里下载一个，因为这个是内核里自带的 2.文件不缺少仍编译失败，使用root权限进行操作，可能是权限问题 3.驱动模块加载后失败，应该是驱动文件配置问题，即与驱动文件关联的Kconfig或者Kconfig.driver等没有进行宏定义
