How to rebuild a RR4/RR64 kernel

[lxnay]

Very easy if you've already done this:

Just do:

Code: Select all

USE="symlink" emerge gentoo-sources
zcat /proc/config.gz > /usr/src/config
genkernel --kernel-config=/usr/src/config --menuconfig --bootloader=grub --gensplash=default all


Kernel menuconfig will show up and let you make changes... then you only need to exit and wait

And how do I get the kernel sources?

At least on the latest XGL edition of RR64, I can not find them in /usr/src/, and I can not emerge them because I have no network because of missing modules (rt2500, uli625x) - that is why I would like to recompile the kernel

Kind of a chicken - egg problem, I guess

Hmmm, I did a DVD2HDD install on my lappy and the sources where installed. But anyways...

You could get on another machine that has an internet connection and using a thumb drive, (or even burn to a cd) the matching vanilla kernel sources from kernel.org and then transfer them over to your machine. Then untar the archive to /usr/src/ and rebuild the kernel to get you up and running. Granted, this would not be a gentoo-ized kernel but it would give you a starting point to work with. Then after you get up on the net, you could emerge everything else.

Hope this helps

Same thing here; the kernel sources are nowhere to be found

Code: Select all

eselect kernel list
Available kernel symlink targets:
  (none found)

Code: Select all

genkernel --kernel-config=/usr/src/config --menuconfig --bootloader=grub --gensplash=default all
* Gentoo Linux Genkernel; Version 3.3.10
* Running with options: --kernel-config=/usr/src/config --menuconfig --bootloader=grub --gensplash=default all

* ERROR: kernel source directory "/usr/src/linux" was not found!

HXC:
is there anything in /usr/src ?

Code: Select all

ls -l /usr/src

you could have the sources installed but not symlinked to anything, hence /usr/src/linux wouldn't exist.

I checked that. /usr/src was totally empty...

HXC:
Well, as I said, I did a DVD2HDD install and got the sources installed

Code: Select all

barcode@desktop ~ $ ls -l /usr/src/
total 2800
lrwxrwxrwx  1 root root      23 2006-02-25 15:24 linux -> linux-2.6.15-reiser4-r1
drwxr-xr-x 20 root root    4096 2006-04-19 21:32 linux-2.6.15-reiser4-r1
drwxr-xr-x 19 root root    4096 2006-04-08 21:35 linux-2.6.16-rc5-xen
drwxr-xr-x 19 root root    4096 2006-04-17 03:59 linux-2.6.16-xen-r1

I guess I could tar up the sources and post them here if anyone needs them, but let me know. But I would suggest emerging the sources (if you can) and running

Code: Select all

zcat /proc/config.gz > current-config

to get the current running kernel config to work with.

Thanks for the offer . However I solved this problem by doing a "emerge -u gentoo-sources". And issued these commands afterwards:

zcat /proc/config.gz > /usr/src/config
genkernel --kernel-config=/usr/src/config --menuconfig --bootloader=grub --gensplash=default all

!!!

Code: Select all

emerge reiser4-gentoo-sources

!!!

To update external drivers you can emerge "module-rebuild" application

Strangly enough /usr/src is also empty in the latest rr64...

@lxnay, what is the correct procedure to fix this?
