Last week, some users encountered an error code while compiling the Fedora Core 3 kernel. This issue can occur due to a number of factors. Now let’s discuss some of them.
Get PC error-free in minutes
This document contains instructions for advanced users who want to compile the kernel from source. Note, however, that whoever designs or runs such a kernel should NOT expect support from certain members of the Fedora kernel team; Here you are pretty much on your own if things don’t go the way you hoped or planned. But hey, you’re a modern user, so you can handle it, right? One way or another, advanced users tune kernels for various reasons:
Kernel Build Dependencies
This doesn’t really apply to most methods, but it does give a very good list of item dependencies related to installation.
# sudo dnf install fedpkg fedora-packager rpmdevtools ncurses-devel pesign grubby
After most people check, enter the keep with command from the top directory associated with the kernel source tree.
Soalso be sure to add the user running my build to /etc/pesign/users and run our user authorization script:
It should be noted that pesign pesign-rh-test-certs is automatically extracted for some, but not all, depending on how one installed pesign. It’s included to make sure you leave it installed. A
Building The Kernel In The Fedora Source Tree
Be sure to browse the list anonymously if you don’t have a Fedora Artist account.
At the time you wrote your wiki, the core was managed with git. Each version of Fedora will be a separate branch. Rawhide track master. A good way to get the tree for the perfect final release is to use git checkout from the top of the source tree you just created.
You can make any adjustments/modifications a person needs at a given time before building and installing RPM packages. You may want to remove comments
RPMs are created in the $ARCH subdirectory, which can then be installed:
Create A Kernel Without Debugging
Branched corn kernels are created with excellenthello, which by default allows developers to help in the early stages of a release. To disable the kernel using debug information, you can follow someone’s instructions above and/or do the following:
Enable Configuration Options
If there are learning options that need to be adjusted for your build, you can add changes to the kernel-local. These changes are applied at creation time.
$git core status
- Your setup will mess up the spine in configs and kernel.spec
$git main package
- postpone changes to clear the tree
let core rrr git pull origin
- Updating git fedpkg to latest tree
Users can now run any other command (like make release)
Create A Brand New Kernel From Exploded Git Trees
Fedora maintains a Fedora git tree containing default values that apply in addition to the vanilla-flavored sources.
Now you can build our core regularly by following the instructions of poisonra. This forest is useful for generating crashes that can be applied to a particular kernel.spec.
Create Kernel From RPM
Reseller guides on this can be found on a separate perfect page. Usually you have to use one of the other types to build the kernel, which is much easier.
Building Kernel Modules (modules Outside The Tree)
This section is for users who are most interested in working on their own kernel module and don’t want to build a full Ritual kernel. There is no need to extract and rebuild the whole kernel to build the module. To build a module for a running kernel, only the appropriate
kernel-devel package is required. Run the following command to install the
kernel-devel part of the package using
su -c 'dnf is blocking kernel development'
You can compile against any version of the kernel, as long as the
kernel-devel schemas are installed for that version. The rest of this section assumes that this site is designed toof this kernel in the instance. no, replace
with your desired version number.
For example, to create a module
foo.ko derived from
foo.c, create the following
Makefile around the directory containing the
obj-m := stuff.oKDIR:= /lib/modules/$(shell name -r)/buildPWD := $(Pwd wrapper)Initially:[TAB]$(MAKE) -C $(KDIR) M=$(PWD) modules
[TAB] Specifies the count character that should come first in line command makefiles.
The above is usually a useful local makefile wrapper that calls kbuild; in general you can easily do things like
# make -C /lib/modules/`uname -r`/build M=`pwd` module# make -C /lib/modules/`uname -r`/build M=`pwd` clear# make -C /lib/modules/`uname -r`/build M=`pwd` modules_install
Building A Vanilla Core
Sometimes a particular Fedora developer will ask you to install a new source kernel (perhaps with a patch added) for testing purposes.If there are multiple iterations, it might be faster for you than for us if the developer has to reverse many different RPMs.
