When using CENTOS 7 with Kernel 4.5, I can not yum install kernel-headers with the same kernel version. I am stuck on 3.10, which is what Centos comes with. How can I install Kernel-headers 4.5 and Kernel-devel which is needed for compiling drivers?

The packages are not in a repo with the mainline kernel updates:

Did you notice that the name of the kernel package you installed was kernel-ml?

Corresponding to that, you need to install kernel-ml-devel to get the corresponding kernel source for compiling drivers against your kernel.

You don't need to install any kernel headers other than this.

  • No package kernel-ml-devel available. -- and kernel-headers is a requirement of gcc, is it not? Yum tries to install kernel-headers 3.10 – user1955162 Apr 08 '16 at 01:07
  • Then you need to re-enable the repo, as I already said! – Michael Hampton Apr 08 '16 at 01:07
  • I don't understand, as I didn't disable it when following a guide to enable it in the first place. I see now that those packages are enabled, will gcc take kernel-ml-headers? – user1955162 Apr 08 '16 at 01:10
  • I guess when i installed kernel-ml it used the repo through the --enablerepo flag. actually enabling the repo fixed the issue of installing kernel-ml development packages, and for those looking to an answer, yes: gcc will take kernel-ml-headers. – user1955162 Apr 08 '16 at 04:09
