How to Compile kernel headers

[ikkem]

Hi I had a question
I wanted to ask how to build kernel_headers for the 2.6.19.3 kernel on debian sarge in order to build the dazuko module
The how to by Falko worked nicely for compiling the kernel source 2.6.19.3 from kernel.org ....thanks for the how to

If you compiled a kernel from the sources, the kernel headers are already installed.

hi....
thanks for reacting I get a kernel headers not found error when building the dazuko module maybe I am missing something....
thanks in advance

[falko]

Did you boot into your new kernel, or are you still using your old one? You can find out by running

uname -r

[ikkem]

I boot into my new kernel but for some reason the headers can't be found....

uname -r  
2.6.19.3-386

I am trying to build the dazuko module to run with antivir

dpkg -i dazuko-source_2.3.2-1_all.deb
m-a a-i dazuko

module-assistant, error message

Bad luck, the kernel headers for the target kernel version could not be found and you did not specify other valid kernel headers to use.

If the running kernel has been shipped with the Debian distribution, please
install the package kernel-headers-2.6.19.3-386. If your kernel source tree (or headers) is located in some non-usual location, please set the KERNELDIRS environment variable to the path of this directory, alternatively) specify the source directory we build for with the --kernel-dir option in module-assistant calls.

thanks in advance

If I think about it - it's possible that the kernel headers aren't installed because in the Debian kernel howto we create a kernel .deb package which doesn't contain the headers.

You can try to combine the Debian kernel howto with this one: http://www.howtoforge.com/kernel_compilation_ubuntu_p2

Run

fakeroot make-kpkg --initrd --append-to-version=-custom kernel_image kernel_headers

instead of

fakeroot make deb-pkg

This should create a kernel headers deb package.

If that doesn't work, you can still compile a kernel the traditional way, without creating a deb package, as shown here: http://www.howtoforge.com/kernel_compilation_fedora_p2
That way the headers will be installed for sure.

thanks for reacting I will try the traditional way hopefully that will be sufficient I could not install the kernel_image with the ubuntu way and the kernel headers were not installed in full because the kernel module builder could not find the kernel headers even after I installed the kernel header package

darkstar:/usr/src# dpkg -i kernel-image-2.6.19.3-custom686_10.00.Custom_i386.deb

I will try the traditional way hopefully it will help....
ikkem....

[ikkem]

I followed the how to

make all
make modules_install
make headers_install
make install

I checked in /boot the ramdisk was not build which made reboot into the new kernel fail (I guess)

I will continue tomorrow.....

[ikkem]

I made the ramdisk

mkinitrd.yaird -o /boot/initrd.img-2.6.19.3-raysun1 2.6.19.3-raysun1

updated grub

update-grub

but I still get a error message of kernel headers not found maybe I missed something....

thanks in advance

[falko]

What's the exact error message, and what kernel version did you try to compile?
