字符驱动设备踩坑

1.编译源码出现：

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 /root/linux-3.5.0/Module.symvers
           is missing; modules will have no dependencies and modversions.

  Building modules, stage 2.
/root/linux-3.5.0/scripts/Makefile.modpost:42: include/config/auto.conf: No such file or directory
make[2]: *** No rule to make target `include/config/auto.conf'.  Stop.
make[1]: *** [modules] Error 2
make[1]: Leaving directory `/root/linux-3.5.0'
make: *** [default] Error 2

解决方案：进入源码目录中执行以下语句

make oldconfig && make prepare

执行完后又出现了错误： linux-内核导入配置 lexer.lex.c错误

解决方法：

sudo apt-get install bison
sudo apt-get install flex

然后又出现错误： fatal error: openssl/opensslv.h: No such file or directory

解决方法：

sudo apt-get install libssl-dev

嗯，又有错误。。。。：Cannot use CONFIG_STACK_VALIDATION=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel" 

解决方法：

apt install libelf-dev
