[SOLVED] "kernel includes do not match the current kernel"

igadoter · 10-30-2011, 01:43 AM

Hi,
I tried to install the proprietary an ATI gpu driver for radeon 9600 on 12.2 v. The installer failed to compile a kernel module. Here is a syslog

Code:

[Message] Kernel Module : Trying to install a precompiled kernel module.
[Message] Kernel Module : Precompiled kernel module version mismatched.
[Message] Kernel Module : Found kernel module build environment, generating kernel module now.
AMD kernel module generator version 2.1
Error:
kernel includes at /lib/modules/2.6.27.7/build/include do not match current kernel.
they are versioned as ""
instead of "2.6.27.7".
you might need to adjust your symlinks:
- /usr/include
- /usr/src/linux
[Error] Kernel Module : Failed to compile kernel module - please consult readme.

Look at the lines

Code:

kernel includes at /lib/modules/2.6.27.7/build/include do not match current kernel.
they are versioned as ""
instead of "2.6.27.7".

(see that empty '""' string?)
The path '/lib/modules/2.6.27.7/build' is a link to the kernel source

Code:

build -> /usr/src/linux-2.6.27.7

And here are the 'includes'

Code:

One of my explanation is that for an unknown reason the installer expects something like 'include-2.6.27.7' - but I don't think its true.

Im running Slackware 12.2 with generic 2.6.27.7 kernel. The system installation is out of stock - no customizations made.

The last thing

Code:

bash-3.1$ uname -r 
2.6.27.7

That's ATI for you. Anyway, you could try "strace" to gain some insight what files the installer is trying to open. Good luck.

igadoter · 10-30-2011, 10:37 AM

Thanks. Good to know about 'strace'

This has nothing to do with ATI. It sounds like a very simple case of the kernel headers not matching the running kernel.

igadoter, what kernel are you running? Did you copy the config file for your kernel from /boot /usr/src/linux-2.6.27.7 and run 'make prepare' in that directory?

2.6.27.7-generic. I've posted 'uname -r' command output. The kernel's source is the kernel commonly shipped with Slackware.

No I didn't. But I'm surprised that such actions are necessary. Recently I installed the same Ati driver but under the recent Slackware version - simply by running the ati installer. I've just realized that then I was running the huge kernel - not the generic one. Maybe this is a solution - temporarily to switch to the huge kernel.
What is this command 'make prepare' for?

adamk75 · 10-30-2011, 01:48 PM

'make prepare' sets up the kernel sources (including the headers necessary to build external modules) to build with the options in the config file.

igadoter · 10-31-2011, 04:11 AM

Thanks adamk75. I'll give a try.

A one step ahead

Look at

Inevitable true. But there are files 'modpost.h' and 'modpost.c'.

Obviously not quite so simple, as they DO match. However, you may be on to something.

igadoter, I assumed you had built the new kernel in the directory /usr/src/linux-2.6.27.7 prior to installing the video driver. If not, please repeat the kernel build process before installing the video driver (cp <whatever> .config ; make oldconfig ; make ; make modules). That should also build the modpost binary.

igadoter · 11-01-2011, 01:51 AM

I almost succeeded. The kernel module was built. Thanks @martinus2u. I followed your direction. But...

Code:

done.
You must change your working directory to /lib/modules/fglrx
and then call ./make_install.sh in order to install the built module.
- recreating module dependency list
- trying a sample load of the kernel modules
failed.

When I was trying

Code:

modprobe fglrx

root@enzo:# modprobe fglrx
FATAL: Error inserting fglrx (/lib/modules/2.6.27.7/kernel/drivers/char/drm/fglrx.ko): Unknown symbol in module, or unknown parameter (see dmesg)

and 'dmesg' tells

Code:

root@enzo:~# dmesg | tail
fglrx: Unknown symbol pci_enable_msi

fglrx: Unknown symbol pci_disable_msi
fglrx: Unknown symbol pci_enable_msi
fglrx: Unknown symbol pci_disable_msi
fglrx: Unknown symbol pci_enable_msi

fglrx: Unknown symbol pci_enable_msi

OK. But nevertheless the thread is solved. I have to open a new thread about the ati driver.
