You
must have a working development environment to compile a Linux
kernel. If you are using LFS or Gentoo you already have one.
If, however, you are using a package based distro, like Mandrake,
SUSE, Debian, or Slackware, then you must install all of the
necessary development packages (gcc, make, kernel source,
etc). Since all of these distro's offer a development bundle
during the install, this chore is simple enough. Most likely
you'll only need to manually install the kernel's source using
your package manager (like on Mandrake, for example). Note,
Fedora no longer distributes a kernel source package.
You must use the kernel source provided by
your distribution for the following to work. Building the
latest kernel from vanilla sources (i.e. ftp.kernel.org) is
beyond the scope of this howto and is NOT recommended if you
are using either SUSE or Fedora.
To compile a 2.6.x framebuffer kernel on
SUSE or Mandrake, launch a command prompt, and enter (or cut
and paste)
su -
cd /usr/src/linux
sed -i "s/^EXTRAVERSION.*/EXTRAVERSION = -mykernel/"
Makefile
make mrproper
zcat /proc/config.gz > .config || cat /boot/config-`uname
-r` > .config
make oldconfig
make menuconfig
Goto Device Drivers ---> Graphics Support
and unselect VESA VGA graphics support
from the menu (i.e. press n to remove it from the kernel).
Change the remaining framebuffer drivers from M to * (i.e.
press y to compile them into the kernel). Exit and save your
modifications. Then at the command prompt enter (or cut and
paste)
make all
make modules_install
VERSION=`grep "^VERSION" Makefile | tr -d ' ' |
grep -o "[^=]*$"`
PATCHLEVEL=`grep "^PATCHLEVEL" Makefile | tr -d
' ' | grep -o "[^=]*$"`
SUBLEVEL=`grep "^SUBLEVEL" Makefile | tr -d ' '
| grep -o "[^=]*$"`
EXTRAVERSION=`grep "^EXTRAVERSION" Makefile | tr
-d ' ' | grep -o "[^=]*$"`
KERNELRELEASE=${VERSION}.${PATCHLEVEL}.${SUBLEVEL}${EXTRAVERSION}
cp arch/i386/boot/bzImage /boot/mykernel
cp System.map /boot/System.map-${KERNELRELEASE}
cp .config /boot/config-${KERNELRELEASE}
mkinitrd /boot/myinitrd /lib/modules/${KERNELRELEASE}
exit
Note, on SUSE use mkinitrd
-k mykernel -i myinitrd instead of the above command.
You will see a few warnings during the kernel
build, so don't be overly alarmed. Warnings are just that,
warnings, and many stable packages generate them for various
reasons. Errors or compilation failures, however, require
a complete recompile. Simply issue the command make
mrproper and start over. If your kernel won't compile
successfully, then your environment is probably goofed. Most
likely you're missing some essential development tools. Using
your package manager (SUSE yast, Mandrake rpmdrake) check
that you have gcc, binutils, glibc, make, ncurses, kernel
source, and kernel headers installed (be sure to install all
the devel packages for these as well).
Once you've successfully compiled the kernel,
edit your grub or lilo configuration (click here
for help), reboot your computer, launch a command prompt and
enter
su
depmod -a
exit
