Kernel 2.6.31 (with Ubuntu patches 11.36) compilation errors

[mo0nykit]

Hello!

I'm learning how to compile and upgrade a Linux kernel. Here's what I did:
Starting from my home folder,
apt-get source linux-source-2.6.31 --download-only
mkdir linux
mv linux_2.6.31* linux
cd linuxThen starting from ~/linux, I have this pre-compilation script
# Pre-compilation script for source tree preparation and patching
tar xzvf linux_2.6.31.orig.tar.gz # unpack the source code archive
cd linux-2.6.31 # cd into the top of the source tree
patch -p1 -i ../linux_2.6.31-11.36.diff # patch the source tree with Ubuntu patches

# (just following instructions from the Ubuntu Kernel/Compile page)
cd ~/linux/linux-2.6.31/debian
chmod a+x rules
cd ~/linux/linux-2.6.31/debian.master/scripts/misc
chmod a+x *
cd ~/linux/linux-2.6.31
debian/rules updateconfigs

cp ../.config ./.config # I already have a .config file backed up (since I was screwing up all the time)
cd /usr/src
sudo ln -s ~/linux/linux-2.6.31 linux # add a symbolic link pointing to the source treeNow I run this command from the top of the source tree, saving the output to a file as well as printing it out to the standard output using tee
fakeroot make-kpkg --initrd --append-to-version=-kit kernel-image kernel-headers | tee -a ../compile-logsAfter a couple of hours or so, I don't get an installable .deb file. I also just found out the tee didn't write the error messages to compile-logs. Here are the errors I get (copied from the terminal):

$Am I missing something? Maybe I should disable the offending drivers in make menuconfig or something.

Thanks in advance for your help!

Hi, try installing the linux header package if you have not already

sudo apt-get install linux-headers-$(uname -r)

@Partyboi2
Yes I've done that already. I did some experiments on my own and did the following


Knowing that the problem lies with LIRC (Linux Infrared Remote Control), I disabled it in make menuconfig (Ubuntu Supplied Third-Party Device Drivers --> LIRC Device Support)
Then I finished the compilation with
fakeroot ccache make-kpkg --initrd kernel-image kernel-headers

I'll refer back to this part of the error message
In file included from ubuntu/lirc/lirc_gpio/lirc_gpio.c:56:
include/../drivers/media/video/bt8xx/bttvp.h:49:23: error: btcx-risc.h: No such file or directoryLooking around the directory
~/linux/linux-2.6.31/drivers/media/video/bt8xx/ btcx-risc.h indeed doesn't exist.

However, btcx-risc.h resides a directory level higher, in
~/linux/linux-2.6.31/drivers/media/video/Which brings me to my next question. Will copying btcx-risc.h to the bt8xx directory eliminate the compile problems presented by LIRC?
