Introduction to kernel compilation In debian (ubuntu)

Introduction to compiling the kernel under debian (ubuntu)-General Linux technology-Linux programming and kernel information. The following is a detailed description. 1) some necessary tools for compiling the kernel:
Apt-get install kernel-package libncurses5-dev fakeroot wget bzip2
2) enter the directory where the kernel should be stored:
Cd/usr/src
3) Get the latest kernel from the official website
Wget http://www.kernel.org/pub/linux/kern....16.20.tar.bz2
(Finger@kernel.org to find the latest stable version number)
4) Move the kernel to/usr/src to create a shortcut
Tar jxvf linux-2.6.16.20.tar.bz2
Ln-s linux-2.6.16.20 linux
5) copy the Kernel configuration file used by the current system to the new kernel directory,
Cp/boot/config-2.6.8.2/usr/src/linux/. config
6) configure the kernel
A] Move the keyboard, select the Load an Alternate Configuration File item, and call. config to Load the kernel option according to this Configuration by default, reducing compilation difficulty;
B] modify your machine. I am a newbie, but I have changed a few places. You can go to the basic area to find reference posts.
C] Save and exit
7) Start Compilation
See the official debian document here.
[
Cd kernel-source-2.4.18 # If This Is Your kernel source code
Cp/boot/config-2.4.18. config # set the current configuration to the default configuration
Make menuconfig # customize according to your preferences
Make-kpkg clean # You must perform this step (per: man make-kpkg)
Fakeroot make-kpkg -- append_to_version-486 -- initrd \ -- revision = rev.01 kernel_image \ modules_image # modules_image can be pcmcia-cs.
$ Cd ..
# Dpkg-I kernel-image *. deb pcmcia-cs *. deb # Installation

]
My practices
Make-kpkg clean
Fakeroot make-kpkg -- revision = custom.1.0 kernel_image
The compilation process is a bit long (it may be that my machine is broken and it took more than 50 minutes). After the compilation, a deb package should be formed under/usr/src: kernel-image -*. deb

8) Next, install the new kernel:

Dpkg-I kernel-image-*. deb

9) create a memory image
Cd/boot
Mkinitrd-o/boot/initrd. img-2.6.16.20 2.6.16.20

10) Modify grub
Vi/boot/grub/menu. lst,
Information in menu. lst:
Title Debian GNU/Linux, kernel BRL. 12-1-386
Root (hd0, 0)
Kernel/vmlinuz-2.6.12-1-386 root =/dev/hda2 ro
Initrd/initrd. img-2.6.12-1-386
Savedefault
Boot
Check and enter new kernel boot Information
Title Debian GNU/Linux, kernel 2.6.16.20
Root (hd0, 0)
Kernel/vmlinuz-2.6.16.20 root =/dev/hda2 ro
Initrd/initrd. img-2.6.16.20
Savedefault
Boot

So far, the kernel upgrade is completed and started once successfully.
