Problem scenario
You are trying to install Darling. You get this error: "./include/linux/uio.h:16:31: fatal error: 1/hash.h: No such file or directory
#include RH_KABI_HIDE_INCLUDE()"
What should you do?
Solution
Run this:
sudo uname -r
Is the kernel version 5 or higher? If not, that is the root cause.
