[CentOS] Does kernel-devel need further configuration after yum install, for driver build ?

In order to build a kernel module outside of a kernel source tree,
I understand it is necessary to set up a makefile containing
lines such as
and quote the KERNELDIR directory to the make system

(e.g. see O'Reilly book on Linux device drivers)

However, doing this with Centos either 'as-is', or even after doing a
yum remove kernel-devel-<version> then yum upgrade kernel-devel,
(to cause a reinstall of the latest version)
leads to a series of error messages, e.g.:

In file included from include/asm/smp.h:18,
                 from include/linux/smp.h:96,
                 from include/linux/sched.h:23,
                 from include/linux/module.h:10,
                 from /home/fred/appbuild/mydriver/mydriver.c:22:
include/asm/mpspec.h:6:25: mach_mpspec.h: No such file or directory

although I am not set up for SMP !

These errors are 'fixed' if I add to the make's CFLAGS,

but I would guess that this should really happen by means of some symlink
trickery, which was set up when the package gets installed.

I do not think that everything else is correct if I do this !

Am I missing another installation step ?
