Hi,

I'm just trying to make a new kernel for me and when I'm making
"64studio:/home/mira/linux-2.6.24.7# mkinitrd /boot/initrd-2.6.24.7-rt20" I'm geting:
"bash: mkinitrd: command not found"
After googling I've tried reinstall "initrd-tools" , but I've got:
"cpio: ./sbin/udevtrigger : Cannot stat : No such file or directory"

Any advice?

Cheers

mira

Is there any HOW-TO for building kernel like .deb?
I was using this HOW-TO: http://rt.wiki.kernel.org/index.php/RT_PREEMPT_HOWTO
and http://www.digitalhermit.com/linux/Kernel-Build-HOWTO.html

Any useful links which can help me?

I will try this.

Thanks for help

Mira

There are several:

http://www.debian-administration.org/articles/90

There are many more if you use google. There is nothing really
challenging about this. If anything I find the Debian way far easier
than any other method of building a kernel. As an added bonus apt/dpkg
knows about my custom kernel and it can get replaced as newer kernels
hit the repositories.

I've just checked links you gave me .... I think they are good starting point.

Thanks a lot

Hi Mira

it works for me like I reported it in this older mail:

Hi

I'm compiling a kernel for the 64 Studio 2.1 default Etch install. Have
I done everything correct?

I found this link by Google: http://forums.debian.net/viewtopic.php?t=17035
And was linked by this side to:
http://www.rdegraaf.nl/index.asp?sND_ID=848152

Also I found: http://sidux.com/PNphpBB2-viewtopic-t-2201.html
And was linked to: http://rt.wiki.kernel.org/index.php/Main_Page
>From there linked to:
http://rt.wiki.kernel.org/index.php/RT_PREEMPT_HOWTO#Patching_the_Kernel

But I tried the German link for Ubuntu:
http://www.ubuntufreunde.de/forum/p189/vanilla_kernel_mit_realtime_preemption_rt_patch.ht ml?highlight=preemption#post189

Instead of version 2.6.26 I used 2.6.24, because MIDI shall not be fine
with kernel ex 2.6.26.

Prep:
64studio:/usr/src# apt-get install build-essential kernel-package
libncurses5-dev bin86
64studio:/usr/src# wget
http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.24.7-rt17.bz2
64studio:/usr/src# wget
ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.24.7.tar.bz2
64studio:/usr/src# tar -xvjf linux-2.6.24.7.tar.bz2
64studio:/usr/src# rm linux-2.6.24.7.tar.bz2
64studio:/usr/src# bunzip2 patch-2.6.24.7-rt17.bz2
64studio:/usr/src# mv linux-2.6.24.7
linux-2.6.24.7-spinymouse-sep-06-2008-rt
64studio:/usr/src# ln -s linux-2.6.24.7-spinymouse-sep-06-2008-rt linux
64studio:/usr/src# cd linux
64studio:/usr/src/linux# patch -p1 <../patch-2.6.24.7-rt17

Copy config file of 64 Studio 2.1 vanilla install:
64studio:/usr/src/linux# cp /boot/config-$(uname -r) .config

Just to be safe, cleaning the folder:
64studio:/usr/src/linux# make-kpkg clean

Starting the configuration:
64studio:/usr/src/linux# make menuconfig

Compiling:
64studio:/usr/src/linux# make-kpkg clean
64studio:/usr/src/linux# make-kpkg -initrd --revision=2.6.24.7
--append-to-version=-rev01 kernel_image kernel_headers

I started compiling at 17:13:xy.

To be continued,
Ralf

PS: Any notes are welcome. I'll do the purchase for the weekend now.
