Whats the error?
Hi Anil
Please do not top post. 
For your error , please verify if /lib/modules/2.6.32-220.el6.x86_64/build is really linking to the folder containing the kernel files.

Thats the issue the link is not there how to create the link.


On your mails please always put cc to the list.
Even if it is centos the build file will be there. And it should have a soft link to the folder containing your kernel source files. first please find out where your source file is . In my system it is at /usr/src/kernels/<version>
In your it should be /usr/src/kernels/2.6.32-220.el6.x86_64

After you find the folder , give the command  "sudo ln -s /usr/src/kernels/2.6.32-220.el6.x86_64 /lib/modules/2.6.32-220.el6.x86_64/build"
