How to compile a debian kernel?


Hi,

I would like to share my process to compile:
which hangs after ...

1)
Code:
apt-get install linux-source 
apt-get install build-essential
apt-get install kernel-package  --no-install-recommends
  (for kpkg)
2)
Code:
cd /usr/src
tar xfvj /usr/src/linux-*tar.bz2
3) vanilla?? what to do because I have no boot directory and nothing to start
Code:
cp /boot/config-`uname -r` .config

4)
Code:
make clean
make nconfig
make
5) wait 20 hours, and take a cup of coffee or several to wait...

6)
Code:
fakeroot make-kpkg --append-to-version=mycustomkernel --initrd buildpackage
7)
Code:
mount /dev/sda1 /mnt/sda1
cp vmlinu[***] /mnt/sda1/boot/vmlinuz
cp init[***] /mnt/sda1/boot/initrd.gz
... and now reboot and pray

This is the method I used to use. I don't do it anymore as I find the Liquorix kernel is fine for my non stable installations.

In Debian it's best to do the whole thing in a fakeroot and built deb packages for the image and headers:

Make a build directory
Code:
$ mkdir ~/build && cd ~/build
Get your kernel source (example is 3.14.2) and extract
Code:
$ wget https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.14.2.tar.xz
Code:
$ tar Jxvf linux-3.14.2.tar.xz && cd linux-3.14.2
Get the config from the running kernel
Code:
$ cp /boot/config-`uname -r` .config
Code:
$ make oldconfig
(it's usually safe to hold down enter here and accept the defaults - if there is a huge jump in versions, the kernel source of the newest kernel from unstable will have a newer debianised config).

Next run the config tool of choice and make changes as required
Code:
$ make xconfig
or
Code:
$ make menuconfig
etc

Clean the source directory
Code:
$ make-kpkg --rootcmd fakeroot clean
Build the kernel, initrd and headers
Code:
$ make-kpkg --rootcmd fakeroot --initrd kernel_image kernel_headers
Install the resulting deb packages (no need for manual installation/copying of bzImage or modules)
Code:
# dpkg -i *.deb
Configure the bootloader and reboot.
