avb-igb build failing, does avb-igb build supports on latest ubuntu 22.04 and kernal 6.5.0-15?

igb_main.c:239:27: error: initialization of ‘vm_fault_t ()(struct vm_fault )’ {aka ‘unsigned int ()(struct vm_fault )’} from incompatible pointer type ‘int ()(struct vm_fault )’ [-Werror=incompatible-pointer-types] 239 | .fault = igb_vm_fault

It looks like you didn't have the last version of igb_avb subrepo.

Go to lib/igb_avb subfolder and checkout latest master branch like this:

git checkout master git pull

Submodules commits are not automatically updated in master OpenAvnu repo.

Thanks; it fixed the compilation issue. But i am getting one more error root@user:OpenAvnu/lib/igb_avb/igb_avb/kmod# ARCH=I210 make make -C /lib/modules/6.5.0-15-generic/build M=/home/user/OpenAvnu/lib/igb_avb/igb_avb/kmod modules make[1]: Entering directory '/usr/src/linux-headers-6.5.0-15-generic' /usr/src/linux-headers-6.5.0-15-generic/Makefile:779: arch/I210/Makefile: No such file or directory make[2]: No rule to make target 'arch/I210/Makefile'.

You must not provide ARCH=I210 when building kernel module. ARCH is used in kernel for different purposes than in OpenAvnu, it means CPU architecture in kernel. So try just "make" without ARCH.

Thanks , it's worked.

Hi @MarcinMiklas,

I have compiled with the latest 6.5.0.15 kernel and the igb_avb latest version, but I was not able to insert the igb.ko into the system.

Please check dmesg output for more details. I don't have that kernel on any of my machines to check myself.

[varahalu10406]

Thanks @MarcinMiklas ; it's fixed with below steps.

sudo apt update && sudo apt upgrade sudo apt remove --purge linux-headers-* sudo apt autoremove && sudo apt autoclean sudo apt install linux-headers-$(uname -r )

Recompiling agb_avb, able to insert the driver,

[MarcinMiklas]

Great, so I am closing the issue.
