CSCE611 OS Env Prepare (Macbook M-chip)

This assumes that you have at the very least set up developer tools and Homebrew on your machine.

Step01, GCC Install

In the class, we need to build a unix-like kernel in X86 arch. Because MacBook with M2 chip is arm arch. So, we can’t use the original gcc in homebrew. Fortunate, there is a x86_64-elf-gcc in home-brew repo:

i686-elf-gcc

Use brew search gcc in terminal, you can find “x86_64-elf-gcc”. So, use “brew install x86_64-elf-gcc” to install it. Now, you can use “aarch64-elf-gcc” to compail the kernel.

All tool intalled by gcc will be store in this path: /opt/homebrew/Cellar/. So you should heve this “/opt/homebrew/Cellar/x86_64-elf-binutils/2.41_1/bin/x86_64-elf-ld”.

Step2, Tools Install

  • Install wget brew install wget
  • Install nasm: brew install nasm
  • Install qemu and bochs: brew install qemu bochs
