If you're interested in what I have, here's an archive link to one of my older posts on this very topic: http://lists.centos.org/pipermail/centos/2005-August/009501.html
that sounds simple enough...I've got a CentOS 4 system that I'm updating right now before I download the module source and compile it. Let's see how far I get.
I'm sort of stuck where you are...
anyone to toss a bone here on compiling kernel modules
I'm following the release notes: Note An exploded source tree is not required to build kernel modules against the currently in-use kernel.
For example, to build the foo.ko module, create the following file (named Makefile) in the directory containing the foo.c file:
obj-m := foo.o
KDIR := /lib/modules/$(shell uname -r)/build PWD := $(shell pwd)
default: $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules
so # ls -l total 204 -rw-r--r-- 1 root root 137 Aug 13 23:36 Makefile -rw-r--r-- 1 root root 140 Aug 13 23:33 Makefile~ -rw-r--r-- 1 root root 118447 Jun 24 12:42 megaraid.c -rw-r--r-- 1 root root 29506 Jun 24 12:42 megaraid.h -rw-r--r-- 1 root root 2808 Jun 24 13:04 scsi.h -rw-r--r-- 1 root root 4146 Jun 24 13:05 scsi_obsolete.h -rw-r--r-- 1 root root 215 Jun 24 13:05 scsi_typedefs.h
# cat Makefile obj-m := megaraid.o
KDIR := /lib/modules/2.6.9-11.ELsmp/build PWD := $(shell pwd)
default: $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules
then running the following...I'm shooting blanks...
# make -w make: Entering directory `/usr/src/megaraid' make -C /lib/modules/2.6.9-11.ELsmp/build SUBDIRS=/usr/src/megaraid modules make[1]: Entering directory `/lib/modules/2.6.9-11.ELsmp/build' make[1]: *** No rule to make target `modules'. Stop. make[1]: Leaving directory `/lib/modules/2.6.9-11.ELsmp/build' make: *** [default] Error 2 make: Leaving directory `/usr/src/megaraid'
Anyone care to toss a bone my way?
Solved
yum install kernel-devel didn't work because like a moron, I was in smp kernel and so I needed to yum install kernel-smp-devel which then made it all work but of course the boot cd is a uni-processor so I will have to wait until I can reboot the production machine into a uni-processor mode to compile a suitable module to test
Please keep us posted on your progress. I too am stuck at Centos 3 because of an old Megaraid controller.

snagged because loading module says I should be compiling for 586 (it's dual Pentium 3 processors - has me befuddled - for the moment)
Ah - there's a 586 devel kernel ;-)
