5)  Make sure you have no stale .o files and dependencies lying around:

You should now have the sources correctly installed.

6) Before compilation we have to configure the kernel by running below command.

#make oldconfig

If you want to carry your existing configuration to a new version with minimal work, use “make oldconfig”, which will only ask you for the answers to new questions.

7) Compile the kernel by make command


8) compile the modules.

           # make modules

9) Install the kernel

              #make modules_install

             #make install

This last command will install new kernel. Note: Installing new linux kernel may make your system UN-stable. So install new kernel with proper guidelines from experts.
