Hi Joakim, When I cross-compiled KNI I only used gcc that comes with Ubuntu, e.g.: sudo apt install gcc-aarch64-linux-gnu libc6-dev-arm64-cross pkg-config-aarch64-linux-gnu
Which Ubuntu version are you using? The Ubuntu18.04 gcc works fine: aarch64-linux-gnu-gcc -v gcc version 7.5.0 (Ubuntu/Linaro 7.5.0-3ubuntu1~18.04) This is a bit strange, since the versions are the same/similar. I am using this meson invocation: meson kni-cross-gcc -Denable_kmods=true -Dkernel_dir=/home/jlinkes/linux --cross-file config/arm/arm64_armv8_linux_gcc /home/jlinkes/linux is where I have my Linux git repo.
