1. Maybe you do not need the full kernel source
If you need to compile a kernel driver module, the chances are you do not really need the full kernel source tree. You might just need the kernel-devel package. (If, however, you are certain that the full source tree is required, please follow the instructions in Section 2.)
In CentOS-5, there are three kernel-devel packages available:
- kernel-devel (both 32- & 64-bit architectures)
- kernel-xen-devel (both 32- & 64-bit architectures)
- kernel-PAE-devel (32-bit architecture only)
In CentOS-4, there are four kernel-devel packages available:
- kernel-devel (both 32- & 64-bit architectures)
- kernel-smp-devel (both 32- & 64-bit architectures)
- kernel-xenU-devel (both 32- & 64-bit architectures)
- kernel-hugemem-devel (32-bit architecture only)
- kernel-largesmp-devel (64-bit architecture only)
If you are running the standard kernel (for example), you can install the kernel-devel package by:
