HOWTO: Kernel compilation

[garba]

i swear one of these days im putting a bounty on people building a custom kernel as root in /usr/src

[weijiantao]

I followed the procedure carefully. However, after building is complete, I can not find *.deb file at all in top level kernel tree. In the end of the build, there is following output,

Hi,

I was at step #2:

sudo apt-get install kernel-package

and I got the following error:

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package kernel-package

I googled but there wasn't much about it, so I figured Ubuntu couldn't download the files. I don't know how to fix it from console but I went to the menu System > Administration > Software Sources.
In the Ubuntu Software tab, I have enabled Source Code, Canonical-supported and Canonical-maintened. I tried again and it worked.

I don't knowhow to fix it from console, maybe someone else can post it.

I guess the problem came from the fact that during Ubuntu installation there was no internet connection, so Ubuntu disabled all the updates through the internet.

Hope it helps, other then this a very helpful tutorial.

I forgot also that:

sudo apt-get install linux-tree

gave me the error:

danilo@danilo-desktop:/usr/src$ sudo apt-get install linux-tree
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package linux-tree

but the command:

sudo apt-get install linux-source

ùworked well and downloaded the source code.

Thank you, Luca_Linux. With your help, and that of tseliot, I successfully compiled and installed my first kernel, 2.6.24.2 . As I told tseliot, have a double shot cappuccino, and I'll donate the cost to Ubuntu.

Thanks again.

You should be able to grab a newer Ubuntu kernel from the repositories or a vanilla from the kernel site and follow this guide.

Hi Just a quick question, I'm following your howto i need to know something.

sudo make-kpkg --append-to-version=-custom kernel_image modules_image

Do i have to type --append-to-version=-custom. Does the append have to be done if i am upgrading the kernel itself to a new one? or will i just type make -kpkg -custom

You said we can rename -custom to whatever we want but can u tell me what, is kernel_image modules_image a command. Can u help me to understand that command

Thanks indvance..
