Preparing kernel headers on BTr3

Preparing kernel headers

There will be occasional times where we'll face the need to compile code, which requires  the kernel headers. Kernel headers are the source code of the Linux kernel. In this first recipe,
 we'll explain the steps required to accomplish the task of preparing the kernel  headers for compilation.

Getting ready 

A connection to the Internet is required to complete this recipe.

How to do it...
 Let's begin the process of preparing the kernel headers:

 1. Execute the following script to prepare the kernel sources:
 prepare-kernel-sources

root@root:~# prepare-kernal-sources
[*] kernal sources seems to be available
scripts/kconfig/conf --silentoldconfig kconfig
CHK    include/linux/version.h
CHK    include/generated/utsrelease.h
CALL  scripts/checksyscalls.sh
[*]  tada!

2. Copy the following directory and its entire contents
 cd /usr/src/linux
 cp -rf include/generated/* include/linux/

3. Now we're ready to compile code that requires the kernel headers.
