How to compile a kernel on Ubuntu 10.04

http://linuxtweaking.blogspot.com/2010/05/how-to-compile-kernel-on-ubuntu-1004.html

• sudo apt-get install fakeroot kernel-wedge build-essential makedumpfile kernel-package libncurses5 libncurses5-dev

Then an error occurs:

The following packages have unmet dependencies: build-essential: Depends: g++ (>= 4:4.3.1) but it is not going to be installed

Solution: Update ubuntu with all packages using update manager.

• Under ~/src/linux-2.6.32, using command

$make menuconfig

I don't know how to change... so I didn't change anything.

• Then I add the home-brewed system call into the file bounds.c (because this file is short).

• I forgot to use this command line below the first time:

sudo update-initramfs -c -k 2.6.32.11+drm33.2-alpha

 Then I got an unbootable kernel :(

Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

• And  I had to make a live CD and boot from CD-ROM

Create two folders under /mnt : /mnt/dev and /mnt/proc
Start with a livecd, open a a terminal

sudo fdisk -l
sudo mount /dev/sdax /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo chroot /mnt 

with the new root folder, cd under /boot and find all the kernel versions.
$update-initramfs -u -k 2.6.32.59+drm33.24-alpha
$update-grub

• After boot up, use $uname to verify the booted version.
