There might be no clean fix without requiring root access, but output an error message that state that ext4 loaded is required might be enough.

How to reproduce?

I did not test it but I supposed it is enough to run the build in a VM with a Linux system that has no ext4 filesystem loaded.
On such a system (mine is a bare install with only btrfs filesystems) where ext4 is not laded running:
./compile.sh kernel BOARD=helios64 BRANCH=edge RELEASE=bookworm BUILD_KSRC=no

Branch

main (main development branch)

On which host OS are you running the build script and observing this problem?

Debian 13 Trixie

Are you building on Windows WSL2?

ext4 module is available on the build host despite the error telling otherwise, and running sudo modprobe ext4 o the build host is a working workaround.

ls /lib/modules/6.7.12-amd64/kernel/fs//ext4
