Toruble with kernel compile

j.todd · 08-17-2008, 05:20 PM

I'm compiling a new kernel with apm support, but I'm having some problems. When I get to make-kpkg I get this (the bold is the error):

exec make -f /usr/share/kernel-package/ruleset/minimal.mk clean
====== making target minimal_clean [new prereqs: ]======
Cleaning.
test ! -f .config || cp -pf .config config.precious
test ! -e stamp-building || rm -f stamp-building
test ! -f Makefile || \
make ARCH=xen distclean
make[1]: Entering directory `/usr/src/linux-2.6.25'
Makefile:514: /usr/src/linux-2.6.25/arch/xen/Makefile: No such file or directory
make[1]: *** No rule to make target `/usr/src/linux-2.6.25/arch/xen/Makefile'. Stop.
make[1]: Leaving directory `/usr/src/linux-2.6.25'
make: *** [minimal_clean] Error 2

What is the reason for this error? I know it says ther's no Makefile, but it should be there; right? I downloaded the kernel from http://www.kernel.org/pub/linux/kern...2.6.25.tar.bz2

I figure I might as well post this error, even though I'm probably only getting it because of the first one. The next step in compiling is

Code:

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

so I do that and get this:

Code:

debian:/usr/src/linux-2.6.25# fakeroot make-kpkg --initrd --append-to-version=-custom kernel_image kernel_headers
exec make -f /usr/share/kernel-package/ruleset/minimal.mk debian APPEND_TO_VERSION=-custom  INITRD=YES

The changelog says we are creating 2.6.25-custom.
However, I thought the version is ..-custom
exit 3
make: *** [debian/stamp-conf] Error 3

That (^) error is probably being caused by the first (I think).

Anyone know why this is happening and how I could fix it?

Thanks for any help.

Hi.

What steps have you taken to get this far?

If the process can't find the makefile, you might be starting in the wrong directory.

There is usually a symlink of your kernel dir. called /linux

/usr/src/linux-2.6.25 linked to /usr/src/linux

cd to /usr/src/linux

Then start the process.

backup the old /boot/.config file

run the selection program,

make xconfig

or if you like the way it is, just do

make oldconfig

then you can begin the compile,

make all (this encapsulates make clean, make bzImage, make modules)

make modules_install

and as root run,

make install

then reboot to see your new kernel,

That's how I do it anyway, except I change the top part of the makefile, to give it my own version name instead of "custom".

See how you go, Glenn

Hmm..my way is a little bit different. I've always done this, and it's worked every time, except this time.

My way, In chronological order:

Code:

su
cd /usr/src
wget wget http://www.kernel.org/pub/linux/kern...2.6.25.tar.bz2
tar xjf linux-2.6.25.tat.bz2

-- This next part I only did during my first attempt at a kernel compile, because someone in irc mentioned this : 'From the kernel source README: "Do NOT use the /usr/src/linux area! This area has a (usually incomplete) set of kernel headers that are used by the library header files. They should match the library, and not get messed up by whatever the kernel-du-jour happens to be." That's why I don't symlink the kernel source to /usr/src/linux anymore --

Code:

ln -s linux-2.6.23.8 linux && cd /usr/src/linux

Code:

make clean
make mrproper
cp /boot/config-`uname -r` ./.config
make menuconfig

-- Now I load the config file for my current kernel, and then make changes to the config --

Code:

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

-- After --append-to-version= I write a name for the kernel, it begins with a minus (-) and has no have whitespace.
Then the kernel compiles (usually) and I install it like --

Code:

dpkg -i fake_kernel_name.deb
dpkg -i fake_kernel_headers_name.deb
shutdown -r now

That's how I usually do it. The guide I learned to do all this from is here.

Oh, I don't recognise anything after make "menuconfig"

I see debian package manager,

I guess that's a good example of difference between distributions.

If you use the "Debian" way of compiling a kernel, it's cleaner because you get a kernel packaged correctly for Debian and tracked properly by the base system. With a generic installation, the kernel will still work, but won't be tracked by the package manager.

While I used to believe that compiling a custom kernel is the best way to go, it's usually a bad idea unless you absolutely cannot do without a feature not enabled in the stock kernel.

GlennsPref · 08-18-2008, 05:51 AM

Yes, I agree.

That is one thing that is not supported very well in mandriva.

That is keeping track of installs from source.

Thanks for the heads up!

regards Glenn

There is an rpm that is meant to keep tabs/track of mandriva-kernel releases. I could be missing something. GW

I was able to get the kernel to compile, I had to disable xen support.

corondan · 01-22-2009, 10:44 PM

just got bitten by this too.
add --arch=x86 or whatever your arch is.. e.g.

make-kpkg --arch=x86 kernel_image

works with xen too.
