Fedora where are kernel headers installed

This information is relevant for developers. BTW, your link to GenToo was not helpful as it states that headers can be newer.

Anyways, I do not want to start a basic disussion about this and I accepted the answer. This topic was automatically closed 28 days after the last reply. New replies are no longer allowed. Now you are good to go with compiling your own or existing kernel modules for software such as VirtualBox and many more.

Remember that before you can compile kernel modules such as device driver on a Linux system, you should have necessary kernel header files installed.

Which Linux distribution you are using? I studied that article, but it is not adding anything new, that solves the problem.

Use the isolinux. You should reboot the machine with the boot media and verify that you are able to boot with it before continuing. Alternatively, on systems with a floppy drive, you can create a boot diskette by installing the mkbootdisk package and running the mkbootdisk command as root.

See man mkbootdisk man page after installing the package for usage information. From the output, determine which packages need to be downloaded for the kernel upgrade. For a single processor system, the only required package is the kernel package.

See Overview of Kernel Packages for descriptions of the different packages. To install the kernel manually, continue to Performing the Upgrade. It is strongly recommended that you keep the old kernel in case there are problems with the new kernel.

At a shell prompt, change to the directory that contains the kernel RPM packages. Use -i argument with the rpm command to keep the old kernel. Do not use the -U option, since it overwrites the currently installed kernel, which creates boot loader problems.

For example:. The next step is to verify that the initial RAM disk image has been created. Ensuring that the kernel and initramfs versions match shows that:.

These are special files created by the kdump mechanism for kernel debugging purposes, are not used to boot the system, and can safely be ignored. You must use the --force option if you want dracut to overwrite an existing initramfs for example, if your initramfs has become corrupt.

Otherwise dracut will refuse to overwrite the existing initramfs file:. Most keep all the packages current by using the Package Manager or as root executing yum update from a command line. Done frequently, and with a decent Internet connection, it doesn't take long, but you've got a bit of catch-up to do. To use the new kernel, you'll need to reboot after the update is done.

From your example, it doesn't even seem to even work It's used on most repos if you look at their examples too: rpmfusion. This was really helpful. I thought i had installed the correct version of kernel headers, a very small difference in name, but it was not correct and failing to build. Above command helped me got the actual one as well as give me better insight into package search.
