[5.4.y] Odroid-XU4 Kernel won't compile

[semidark]

Hi,

i installed the latest Ubuntu minimal image ubuntu_5.4. I'm trying to rebuild the Kernel so I can fiddle arount with it eventually.

But after downloading the 5.4.y branch and using the current kernel config...

wget https://github.com/hardkernel/linux/archive/refs/heads/odroid-5.4.y.zip
unzip odroid-5.4.y.zip
cd linux-odroid-5.4.y/
cat /proc/config.gz | gunzip > .config

Building...

nice make -j`nproc` bindeb-pkg

Fails with this error message:

[...]

Any ideas why this happends?
