[root@embedded secbulk]# make -C /lib/modules/`uname -r`/build M=`pwd` modules

make: *** /lib/modules/2.6.32-71.el6.i686/build: 没有那个文件或文件夹。 停止。

[root@embedded secbulk]# make -C /lib/modules/`uname-r`/build M=`pwd` modules

bash: uname-r: command not found

make: *** /lib/modules//build: 没有那个文件或文件夹。

停止。

这时须要安装kernel-devel
