Hello,

I am trying to build the kernel on Ubuntu 20.04 and I am not able to go past this error

# merged configuration written to /home/ubuntu/android-kernel2/common/arch/arm64/configs/arpi_defconfig (needs make)
#

The header types.h is available under /usr/include/sys

$ ls -l /usr/include/sys/types.h
