The purpose of this tutorial is to help how to compile and install a new Linux kernel for x86: Configure, build, and install

Conventions used in this tutorial:

• • $ execution on the command line by a non-privileged user

  • # execution on the command line by a superuser

  • the actual command to be executed on the command line or code of program to be compiled

II. Step by step how to compile Linux kernel version 3.0.1 under Ubuntu 10.04

2.1. Compilation requirements

First, what needs to be done is the installation of required prerequisites

• • Ubuntu 10.04: Install Ubuntu 10.04 on your computer as a virtual machine or a secondary operating system

  • gcc upgrade to version 4.x. Check your version by follow command

#gcc -v

• • Update the libncurses and Grand Unifiled Bootloader, version 2(Grub2: Grub 2 is the default boot loader and manager for Ubuntu which presents a menu and waits user input or automatically transfers control to an Operating System kernel)

# apt-get install libncurses-dev

# apt-get install grub2

2.2. Configure, build, install kernel

Step #1 Dowload he latest kernel from kernel.org

#wget http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.0.1.tar.bz2

Step #2 Extract tar file into /usr/src

#tar -xjvf linux-3.0.1.tar.bz2 -C /usr/src

Step #3 Configure kernel

#cd /usr/src/linux-3.0.1

#make menuconfig

figure 1: main menuconfig

figure 2: networking option

You have to select different options as per your need. Each configuration option has HELP button associated with it so select help button to get help. This window lists that can be compile into or loaded by kernel and shows the three choices for most configuration options:

• • Y: Selecting y compiles the option into the new kernel

  • M: Selecting m causes the option to be loaded as a dynamically module by the kernel

  • N: Selecting n tells the kernel not use the configuration option

Step #4 Compile kernel

#make

#make modules_install

Step #5 Install kernel

So far we have compiled kernel and installed kernels modules. It is time to install kernel itself.

#make install

It will install three files into /boot directory as well as modification to your kernel grub configuration file

• • System.map-3.0.1

  • config-3.0.1

  • vmlimuz-3.0.1

Step #6 Create an initrd image

#update-initramfs -c -k 3.0.1

Result of step 5 and 6:

Step #7 Modify Grub configuration file

In this tutorial i want to display list kernel version on the screen when start, so i edit grub follow picture

Result:
