Hardy(8.04) is a little different from all the other versions when building a kernel. Only Hardy has two packages for kernel installation: linux-image, linux-ubuntu-modules. If you do not install the latter one, your sound card and network card will can not be recognized.
Today, I built the kernel from the ubuntu source(not the original kernel source). So, I could use the including debian scripts for convenience. Here’s the steps:
1. Tools:
|
1 |
# sudo apt-get install build-essential fakeroot linux-kernel-devel kernel-wedge |
2. Sources:
The source will be downloaded in the current directory.
|
1 2 |
# sudo apt-get source linux-source-2.6.24 # sudo apt-get source linux-ubuntu-modules-2.6.24 |
3. Customize:
cd into “linux-2.6.24” root.
I selected “core2” as my custom name.

1 2 3 4 |
# cp debian/control.d/vars.generic debian/control.d/vars.core2 # cp debian/abi/2.6.24-27.68/i386/generic debian/abi/2.6.24-27.68/i386/core2 # cp debian/abi/2.6.24-27.68/i386/generic.modules debian/abi/2.6.24-27.68/i386/core2.modules # cat debian/config/i386/config debian/config/i386/config.generic > debian/config/i386/config.core2 |
Then patch some files:
*) debian/scripts/misc/getabis:
From: getall i386 386 generic server virtual
To: getall i386 386 generic server virtual core2
*) debian/rules.d/i386.mk:
From: flavours = 386 generic
To: flavours = 386 generic core2
4. Build:
|
1 2 |
# fakeroot debian/rules clean # CONCURRENCY_LEVEL=2 AUTOBUILD=1 NOEXTRAS=1 skipabi=true fakeroot debian/rules binary-core2 |
If you get errors like:
|
1 2 |
> /home/gonwan/Documents/linux-2.6.24 is not clean, please run 'make mrproper' > in the '/home/gonwan/Documents/linux-2.6.24' directory. |
Run the following command, it is issued by the Makefile:
|
1 |
# rm -rf .config include/config |
5. Done:
My PC has a P4-2.6c CPU. It took about 90 minutes to finish. The kernel also consumed about 2G storage. After all, three *.deb files were generated:
*) linux-headers-2.6.24-27-core2_2.6.24-27.69_i386.deb
*) linux-image-2.6.24-27-core2_2.6.24-27.69_i386.deb
*) linux-image-debug-2.6.24-27-core2_2.6.24-27.69_i386.deb
6. Customize modules:
First, generate prepare scripts:
|
1 2 |
# cat debian/config/i386/config debian/config/i386/config.generic > .config # make prepare scripts |
cd into “linux-ubuntu-modules-2.6.24-2.6.24”
|
1 |
# cp debian/control.d/vars.generic debian/control.d/vars.core2 |
Note: Custom modules name must match the custom kernel name, say “core2”.
Then patch some files:
*) debian/rules.d/i386.mk:
From: flavours = 386 generic
To: flavours = 386 generic core2
*) debian/rules.d/0-common-vars.mk (To prevent error in build step, debian/rules.d/3-udebs.mk):
From: disable_d_i = no
To: disable_d_i = true
Now generate new debian/control, which includes new custom kernel:
|
1 2 |
# rm debian/control.stub # debian/rules debian/control.stub |
7. Build modules:
|
1 |
# AUTOBUILD=1 fakeroot debian/rules binary-arch arch=i386 flavours=core2 KDIR=/home/gonwan/Documents/linux-2.6.24 |
8. Done again:
This time, it took 30 minutes and consumed 300M storage. Two *.deb files were built:
*) linux-headers-lum-2.6.24-27-core2_2.6.24-27.45_i386.deb
*) linux-ubuntu-modules-2.6.24-27-core2_2.6.24-27.45_i386.deb
9. Install kernel:
Just double-click or install using the dpkg utility. Here’s my screen-shot:
