Code Build and Run Issues

[eramax]

Hi,

I tried to build and run the code, It seems there are two problems as shown in the logs

I had to update the makefile LD flags since there is a flag not found in LD, I tried many LD versions and packages but all doesn't have this flag.

LDFLAGS = -nostdlib #-nostartfiles

Could you please help me to make the code up and running?

Hi.
Maybe I fixed this issue in this version so please try to build in your environment.

Thank you.

NOTE: This repository is my hobby project, so this OS is so buggy. If you are looking for a simple OS for aarch64, I recommend xv6-aarch64.
