Kernel Headers?

[Dale Satterfield <dales dsq950 com>]

I have installed Redhat 8.0 professional, which installs a 2.4.18-14 
kernel version. The file linux/module.h includes linux/version.h. This 
file says its version is 2.4.9-9. This is NOT consistent with the 
version of kernel that actually gets installed. Shouldn't it ????????

Installing the kernel source package does not resolve this. The glibc 
header package was installed and did nothing to this. Going on to the 
redhat network and looking at the 8.0 channel, there is NO 
kernel-headers package available.

I am trying to go through the examples of the book Linux device 
drivers, second edition. So I would like a standard install to not 
cause all sorts of version and header not found problems before I even 
get to writing the driver I want to do. In those examples he also 
includes a file $(KERNELDIR)/.config. The period before the config is 
not a typo on my part. I have searched for this file and it doesn't 
exist.

So, commenting out the include, and using a make file with KERNELDIR 
defined as /usr/src/linux-2.4, I can get the module to compile, but 
insmod says that loading the module will "taint" the kernel.
It loads and prints the Hello world message to the log, and I can 
remove it and nothing appears to break, but should I have some other 
package with the right headers in /usr/src/linux?

Note that I also eventually went to the redhat network and upgraded my 
kernel to 2.4.18-18.8.0smp, and got the sources for  it. Nothing 
changed with respect to /usr/src/linux and the 2.4.9 crap.
