I'm needing to custom compile a kernel to enable some very specific hardware features that are not on by default and have to be compiled in. I started following this guide but it seems to be slightly outdated for 12.04 onwards as some commands fail with missing source packages.
https://help.ubuntu.com/community/Kernel/Compile
What is the easiest way to rebuild the current kernel source so I can tweak the options I need?
These steps are very general and apply to every package in Ubuntu/Debian.
This will download the source package and applies all Ubuntu patches.
apt-get source linux-image-3.... # select the exact package you want
Install all build dependencies.
sudo apt-get build-dep linux-image-3...
Enter the directory of the source.
cd linux-... # change accordingly
Do the changes to the source you need.
After finishing the edits, add a new version to the changelog (else it's going to complain the source doesn't match):
dch --local mysuffix
Build it with unsigned changes file and unsigned source package (for local testing):
debuild -uc -us
This will take a while!
Find the packages one level below:
ls -al ../*.deb
Install them like any other package.
