This is not a howto or something remotely close, it‘s just a note i made cause i kept forgetting how to compile the kernel since i do it very rarely :P
First we need some extra packages to compile the kernel in the debian way:
apt-get install make gcc bin86 libc6-dev kernel-package module-init-tools
That will let you use the same old menuconfig in a console(doesn‘t need X) or terminal.
If you want to configure the kernel in X you have 2 options xconfig and gconfig.
xconfig used Tk in kernels 2.4 but in 2.6 it changed to a QT interface so if you use KDE or simply want to use the QT interface to configure the kernel do the following:
apt-get install libqt3-dev make gcc bin86 libc6-dev kernel-package module-init-tools
If you use Gnome or want to use the GTK interface:
apt-get install libglade2-dev make gcc bin86 libc6-dev kernel-package module-init-tools
module-init-tools is the package to manage modules in 2.6, it does the same modutils did for 2.4 kernels.
If you want to compile a kernel with initrd install also the
Ok now lets get the kernel source, you can use the sources from kernel.org or use the ones in debian, i use the debian ones since they include fixes and patches.
root@escaflowne:/usr/src/linux$ apt-cache search kernel-source-2.6 --names-only kernel-source-2.6.6 - Linux kernel source for version 2.6.6 with Debian patches kernel-source-2.6.7 - Linux kernel source for version 2.6.7 with Debian patches kernel-source-2.6.8 - Linux kernel source for version 2.6.8 with Debian patches kernel-source-2.6.9 - Linux kernel source for version 2.6.9 with Debian patches root@escaflowne:/usr/src/linux$
Those are the available kernel source packages for unstable/sid at the moment of writing.
apt-get install kernel-source-2.6.9
That will install the sources in /usr/src:
Unarchive the sources:
tar jxf kernel-source-2.6.9.tar.bz2
Create a link called linux that points to the source dir:
ln -s kernel-source-2.6.9 linux
Then cd to linux dir and configure the kernel... don‘t rush, there are a lot of options in there but you only have to set them the first time you compile a kernel, next time you just need to update the config.
(in case you have a old kernel .config this updates the config with the new options, so in this example next time you compile a kernel, let‘s say 2.6.10, you just have to do a
cp /usr/src/kernel-source-2.6.9/.config /usr/src/kernel-source-2.6.10/
and use the
(to use the ncurses interface in a console or terminal)
(to use the QT interface)
(to use the GTK interface)
OK now its time to compile the kernel
Or to create a kernel with initrd
make-kpkg --initrd kernel_image
Now that you have the kernel compiled and the kernel package created you just have to install it.
cd /usr/src dpkg -i kernel-image-2.6.9_10.00.Custom_i386.deb
It will ask you if you want to make bootdisk, do it... just in case, and if you want to install lilo with the /etc/lilo.conf config also say yes, if you dont the new kernel won‘t boot up.
If you use initrd don‘t forget to check if
/etc/lilo.conf has the
initrd=/initrd.img option in the section of the new kernel.
If it has add
do_initrd = Yes to
That‘s it! Now reboot and try the new kernel.
This is a very basic text(i can´t even call it a Howto) but if you think something should be here feel free to tell me.
