Missing net/gso.h on Raspberry Pi Debian 11 Bullseye - dependency problem?

[1Godhell]

Can’t compile kernel module on Raspberry Pi - missing net/gso.h from sources, although it's in place.

Operating System: Debian GNU/Linux 11 (bullseye) Kernel: Linux 6.1.21-v8+ Architecture: arm64

apt-get full-upgrade

cd /home/***/***
git clone --depth=1 https://github.com/raspberrypi/linux
sudo apt install -y software-properties-common python3-launchpadlib gnupg2 linux-headers
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 57290828

echo "deb-src https://ppa.launchpadcontent.net/amnezia/ppa/ubuntu focal main" | sudo tee -a /etc/apt/sources.list
sudo apt-get update

sudo apt-get install -y amneziawg

• same make output, missing net/gso.h.

Of course net/gso.h is in its place inside the kernel source tree.

Thank you!

The same problem here. Raspberry PI, Debian 12. Is amneziawg supposed to work on Arm 64?

[ntoskernel]

same here

@1Godhell you seems to be building against kernel version higher than installed (current branch in https://github.com/raspberrypi/linux repo is rpi-6.6.y while you are building on 6.1 kernel).

Obtain relevant kernel source by specifying branch in git clone command like -b rpi-6.1.y.
