Linux Kernel Compiler

To compiler linux kernel , we can get and download full source from www.kernel.org , choose the same version kernel with your linux .

Check you own linux kernel version:

uname -r

3.0.XX..

In the commond line , can use curl to download the resource

cd ~

curl www.kernel.org/pub/linux/kernel/v3.0/linux-3.0.56.tar.bz2 > linux3.0.tar.bz2

Then uncompress the resource file:

tar -jxvf linux3.0.tar.bz

cd linux3.0.tar.bz

Delete the *.o file use commond below

make mrproper

Then we can choose which content or module can be compiler freely:

make menuconfig

If can't use the 'make menuconfig' it need to install a library ncruses-devel

apt-get install ncruses-dev

After config the content and module which will be compilered , it's time to compiler it:

make clean

make bzImage

make modules

The 'make bzImage' and 'make modules' will spend lots of time , please pay attention and wait for a minute .

Finish compiler kernel , move file to boot directory:

cp arch/i386/boot/bzImage /boot/linux3.0-56

cp System.map /boot/System.map3.0-56

Then add grub config to grub.cfg or menu.lst file

menuentry 'Ubuntu, with Linux 3.0.0-56-generic' --class ubuntu --class gnu-l    inux --class gnu --class os {
         recordfail
         set gfxpayload=$linux_gfx_mode
         insmod gzio
         insmod part_msdos
         insmod ext2
         set root='(hd0,msdos10)'
         search --no-floppy --fs-uuid --set=root c3a2f48c-75b5-45c8-aabe-1566    a89e1cb3

reboot the system
