As per this,
dasb@ree-du1sdd5:~/lkp-tests$ mkdir build_dir && cp config build_dir/.config
cp: cannot stat 'config': No such file or directory
So I have generated .config and copied as config
Than I got the the below issue,
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-13.2.0 ~/lkp-tests/kbuild/make.cross W=1 O=build_dir ARCH=arm64 olddefconfig
-bash: /data/dasb/lkp-tests/kbuild/make.cross: No such file or directory
Can you please provide the details how to get this tool chain?
So that I can reproduce and fix the issue in same environment.
Cheers,
Biju
