安装主要是按照这个网址的步骤来的：http://ixdba.blog.51cto.com/2895551/526452
执行到make步骤时，出错：

找不到/lib/modules/3.5.0-23-generic/build/include/linux/version.h
可以执行以下命令查看系统是否安装了kernel headers
ls /lib/modules/`uname -r`/build/include/linux/version.h
如果得到关于额米有这个文件的信息，比如：
ls: /lib/modules/2.6.15-23-386/build/include/linux/version.h: No such file or directory
这时，就需要安装headers
apt-get install linux-headers-`uname -r`
