小弟做6410的ds18b20驱动模块的时候，编译的时候出现了以下问题：
ERROR: Kernel configuration is invalid.
include/linux/autoconf.h or include/config/auto.conf are missing.
Run 'make oldconfig && make prepare' on kernel src to fix it.
WARNING: Symbol version dump /usr/src/redhat/BUILD/kernel-2.6.21/vanilla/Module.symvers
is missing; modules will have no dependencies and modversions.
请问这是内核缺少头文件还是怎么回事啊？如何解决呢？谢谢。。。
