llvm-objdump command is not installed during Install development tools step

[aliparlakci]

In section Your first kernel debugging, the book runs the following command:

llvm-objdump -d kernel.elf

However, llvm-objdump is not installed and the book does not tell how to.

In MacOS, gobjdump should be used. It is installed as part of brew install binutils. Unfortunately, brew does not create a soft link of the binary inside the default binary path (/opt/homebrew/bin). You should run:

$ cd /opt/homebrew/bin
$ ls -l ../Cellar/binutils/<version>/bin/gobjdump
$ link ../Cellar/binutils/<version>/bin/gobjdump  gobjdump

Did you check the /opt/homebrew/opt/llvm/bin/ directory? llvm-objdump and other utilities would be installed in that directory including clang that supports 32-bit RISC-V CPU.

Good point. I plan to update the section to cover the Homebrew issue and to introduce Nix (#32).
