Can't compile the ubuntu kernel sources

[Sidoney]

I could install the ubuntu kernel sources with "apt-get source linux-image-$(uname -r)" and patch them with "zcat linux_3.8.0-31.46.diff.gz | patch -p0 2>&1 | tee patch.out" but i can't compile:

* make oldconfig and make module_prepare work but report errors:

* make all ends with an error:

* make modules ends with an error:

make: *** [drivers] Error 2

I also tried it with the unpatched sources, but the errors do remain.
So it seems something is missing, although i never had such problems under OpenSuSE or Debian, but what?

Hello,

i would like to help you, but i don't know exactly what you are doing there with a patch. I would try the
kernel compilation in that way. You need

sudo apt-get install linux-source build-essential kernel-package

After that you can find the sources in

drwxr-xr-x 4 root root 4096 Mär 22 13:54 /usr/src/linux-source-ver3.2.1
lrwxrwxrwx 1 root root 45 Mär 20 01:07 /usr/src/linux-source-ver3.2.1.tar.bz2 -> linux-source-3.2.1/linux-source-3.2.1.tar.bz2

untar the package, change to the folder and use

cp /boot/config-`uname -r` .config

to use your current kernel settings for the new one. Then
you can do

yes "" | make oldconfig

and build a deb file using

make-kpkg --initrd buildpackage

You can install the resulting deb file with

sudo dpkg -i linux-image-******.deb

and proof after a system restart if the new kernel is running.

uname -a

use

cp /boot/config-`uname -r` .config

to use your current kernel settings for the new one. Then
you can do

yes "" | make oldconfig

That makes no sense because make oldconfig overrides the .config you copied before.
And i tried both versions of .config, but make all always ends with the same error

and build a deb file using

make-kpkg --initrd buildpackage

You can install the resulting deb file with

sudo dpkg -i linux-image-******.deb

I need no package, no other kernel, i only need some modified modules!
I only want to have some modifications to be active by compiling and loding modified modules.

For comparison i downloaded a kernel source from kernel.org and after make oldconfig i could compile the kernel and all modules without problems!
So there is a bug in the kernel sources from ubuntu and this also conflicts with the GPL.

I finally found the problem: It is necessary to start with

make distclean

because make clean or make mrproper is not enough.
So the problem is some trash in the ubuntu kernel sources.
After make distclean i could compile with

yes "" | make oldconfig
make modules_prepare
make -j2 all
