Simple question from a novice:
I am recompiling a kernel module.
During make I get the message "You do not appear to have the sources for the 2.6.9-67.0.7.EL kernel installed"
How do I install the sources with yum. AND do I need all the sources OR do I really just need the headers?
I have tried " yum install linux-headers-`uname -r` "
but it can't find anything to install.
Thanks for your help.
Chris.

It is best not to cpmpile on your server, but on a CentOS 4.6 machine (on which SME Server is based) and I would refrain from compiling anything if you are a linux newbie.
If you really would like to have a go, you should not install linux-headers, this is a package that does not exist on RHEL/CentOS based systems, I think you need kernel-devel:
yum install kernel-devel

Good advice (not to do it) BUT continuing anyway:
I think I can see my problem:
[root@storm2 ~]# uname -r
2.6.9-67.0.7.EL
[root@storm2 ~]# rpm -q kernel
kernel-2.6.9-67.0.1.EL
kernel-2.6.9-67.0.7.EL
[root@storm2 ~]# rpm -q kernel-devel
kernel-devel-2.6.9-67.0.15.EL
[root@storm2 ~]#
SO: I am running 0.7.EL
I have installed 0.1.EL and 0.7.EL
BUT my kernel-devel is 0.15.EL
Checking in /lib/modules/2.6.9-67.0.15.EL has a directory build which I think indicates that kernel-devel is there.
Since I can't load kernel-devel-2.6.9-67.0.7.EL, it can't find it,
Should I update the kernel to 0.15.EL (yum install kernel--2.6.9-67.0.15.EL is that correct),
or is there a better answer.
I am learing slowly, thanks for your help.

Since you seem to have messed up your system already by installing all sorts of development libs I really advise you no to go any further...

BUT my kernel-devel is 0.15.EL

It seems an update is released somehow for the kernel-devel, but not for the kernel itself... which seems strange to me. However you can easily install kernel-devel for your current version by installing like this (as long as you run the single processor kernel):
yum install kernel-devel-`uname -r`If you are running another kernel you should drop the suffix after EL that is reported by the uname -r command. In your case it would read:
yum install kernel-devel-2.6.9-67.0.7.EL
When I do so on my test machine it looks like this and does work:
yum install kernel-devel-2.6.9-67.0.7.EL

Its as though it thinks its already installed. But yum remove kernel-devel-2.6.9-67.0.7.EL says that no packages match that name.
I must have done something wrong at some stage, but how to recover?
Thanks,
Chris.

Perhaps you should remove the newer ones, with a version number higher than your current kernel.
-
THAT was the correct answer!
I did yum remove kernel-devel
and it removed 67.0.15.EL
I then tried yum install kernel-devel and it TRIED to reinstall 67.0.15.EL so I aborted.
I then tried yum install kernel-devel-2.6.9-67.0.7.EL
AND IT WORKED.
I have now been able to compile my little module.
Thanks for all your help.

You're welcome, although I suggest you install a sepcial (virtual) machine for it if you need to do this more often, with the CentOS version installed on which SME Server is based.
