This wiki page will help you build your own non-debugging build kernel. Branched kernels are built with debugging enabled by default in the early stages of the release to assist developers.
Getting the source from git
First things first, you'll need the kernel fedpkg source, and the necessary build depends:
(as root) # yum install fedpkg fedora-packager rpmdevtools
# yum-builddep kernel
(as your user) $ fedpkg co -B kernel
This will create a kernel/ subdirectory hierarchy under your current working dir with a dir for each Fedora branch, the rawhide kernel will be located in the master branch.
Building a non-debugging kernel
The following example assumes building a kernel for F-14, which is currently based on the 2.6.35 stable series.
$ cd kernel/f14
kernel/f14 $ make release
This make target will modify your checkout of the F-14 source to generate both a kernel and kernel-debug rpms.
kernel/f14 $ fedpkg local
fedpkg local will chug away for a very long time (on most systems) building the kernels for your currently running architecture. See another article for how to generate an SRPM and do more complicated things like mock building.
When it completes the subdirectory
kernel/f14/x86_64 (or i686 or whatnot) will have a kernel rpm with debugging disabled by default. These can be installed with, for example:
kernel/f14/x86_64 # yum localinstall --nogpgcheck ./kernel-$version.rpm
$ cd kernel/f14
kernel/f14 $ git status
- your tree will be dirty in the configs and kernel.spec
kernel/f14 $ git stash
kernel/f14 $ git pull origin
Please run a Fedora built debugging kernel when you report bugs, as they contain invaluable debugging information to assist developers.
