Kernel Blues

[todgerme]

I hate trying to get Kernel modules working.

Anyway I am trying to follow the NFS DRBD guide and I can't get past the following when I try to make the DRBD module:

/usr/src/modules/drbd/drbd# make
grep: /lib/modules/2.6.8-2-686-smp/build/Makefile: No such file or directory
grep: /lib/modules/2.6.8-2-686-smp/build/Makefile: No such file or directory

Calling toplevel makefile of kernel source tree, which I believe is in
KDIR=/lib/modules/2.6.8-2-686-smp/build

trying to make dep ...
make[1]: Makefile: No such file or directory
make[1]: *** No rule to make target `Makefile'. Stop.
I'll ignore this error, but this can cause inconsistencies!

Sorry, automagic adjustment of drdb_config.h failed.
For well known 2.6. kernels, no adjustment to the shipped drbd_config is necessary.
You need to verify it yourself.

Looking at /lib/modules/2.6.8-2-686-smp/build where it complains about Makefile not existing everything is symlinked up a directory and then downwards again but this directory doesn't exist so I am very confused!

Anyone ideas? Debian Sarge.

If no-one has ideas can someone post me a smp 686 enable kernel + headers with all the drdb stuff already enabled?

Do you have the kernel-headers for kernel 2.6.8-2 installed?

[todgerme]

I did, but I have since given up on Debian and went for Ubuntu 6.06 server instead. It only compiles under gcc 4 under Ubuntu but it did compile. Haven't completely followed the guide so I could be back for more tech support shortly :)

Back to Debian for another system, an Opteron system using an AMD64-K8 kernal, compiling the DRBD module I get the following error:


Calling toplevel makefile of kernel source tree, which I believe is in
KDIR=/lib/modules/2.6.8-12-amd64-k8-smp/build

test -f ../scripts/adjust_drbd_config_h.sh && \
KDIR=/lib/modules/2.6.8-12-amd64-k8-smp/build /bin/sh ../scripts/adjust_drbd_config_h.sh

Using unmodified drbd_config.h

Can anyone offer any advice on how to get around this? The module compiles when using a 686-smp kernel, but the system tends to randomly lockup unless you use the proper K8 kernel so I really need to get this working!?

Are you trying to compile a 64bit kernel on a 32bit system?

[todgerme]

It is am AMD64 using a x86 Debian with an AMD-K8 kernel if that makes any sense. I guess most of the OS would be 32bit but didn't want to go for any of the unofficial AMD64 versions of Debian. I am going to try the AMD64 version of Ubuntu to see what happens.
