Build of pivccu-modules-dkms fails on Ubuntu 24.04.03 LTS

[Empor-co]

I lately had to setup a new RPI and struggle to build the dkms module.

make[1]: Leaving directory '/usr/src/linux-headers-6.8.0-100-generic'

having similar issues with hwe kernel 6.17 trying to install 1.0.88 from PR: 575

Provided fixes like:

sudo apt remove --purge linux-headers-*
sudo rm -rf /usr/src/linux-headers-*
sudo apt autoremove && sudo apt autoclean
sudo apt install linux-headers-generic
sudo apt install --reinstall pivccu-modules-dkms

didnt help fixing it either

I have downgraded to kernel 6.8.0 and build finishes without errors. So I think Ubuntu has modified kernel sources, problem seems to be upstream Ubuntu...

[Commifreak]

Same issue for me

[leon-eck]

I finally got it working with kernel 6.8 and a build deb package based on PR:575

I sadly don’t know all the necessary steps it took sadly to get it running, I was using AI assisted steps.

In the end the installed Linux headers seemed quirky. I got rid of them and all their traces and reinstalled them explicitly, not only via the generic dependencies.

At some point it just worked and I stopped questioning it. I’m waiting for a stable release before touching it again.

[df8oe]

The recent sources AND the one in the pending #575 ARE stable and working. The issue seems to be located in Ubuntu. I am using Archlinux (because I do not want to ride dead horses like completely outdated kernels), my architecture is aarch64 and everything is working fine (also if I downgrade kernel to 6.8.0). I left Ubuntu in 2005 because of incompatibilities with Debian (Ubuntu turns its own wheels...) and this was an excellent decision...

[Commifreak]

Is this still an issue? I hoped that with #575 the build would work on Ubuntu now but after cleanup ( Step1 https://github.com/OpenCCU/OpenCCU/wiki/Installation-Docker-OCI#potential-container-startup-errors ) the error still remains?

Anything I can provide?

@Commifreak Most likely your Kernel Headers are invalid and the issue will be gone, when you reinstall the kernel headers. This is a known issue on Ubuntu, that there sometimes the installation of the kernel headers installs them with deactivated kernel module signing even if the kernel has activated kernel module signing and then loading of a dkms built module will fail with exactly that error.

[Commifreak]

I reinstalled twice using the mentioned method. Is there another way to do it?

[Commifreak]

SI confirms your concern and tests show that your tip is the current issue on my side. The steps mentioned on the linked wiki did not helped.

module generic_raw_uart: .gnu.linkonce.this_module section size must match the kernel's built struct module size at run time

I try to clean up and reinstall everything and post feedback

Thanks for now

[Commifreak]

Solved now @alexreinert

The mentioned procedure was NOT enough.

I had to reinstall the other kernel packages as well in order to get it working:

sudo apt install --reinstall \
  linux-image-$(uname -r) \
  linux-modules-$(uname -r) \
  linux-modules-extra-$(uname -r) \
  linux-headers-$(uname -r) \
  linux-headers-generic \
  dkms \
  build-essential

sudo reboot

sudo apt install --reinstall pivccu-modules-dkms

was the final solution:

Maybe worth mention/update the instrcution at https://github.com/OpenCCU/OpenCCU/wiki/Installation-Docker-OCI#potential-container-startup-errors would be awesome @jens-maus ?

Thanks for all help!
