Talking to Metal

Not as good as Heavy Metal but it's a good challenge trying to master some stuff in machine (metal) code.

This repo contains a collection of Assembly programs that I've been writing only for study and practice purpose. So please don't take it that serious :-)

Assembler

All programs are written for Intel x86-64 machine and macOS operating system hence the executable format used must be the "Mach-O 64".

For this reason I strongly recommend the use of the nasm assembler.

You can install it via Homebrew:

brew install nasm

Running

For running one of the programs you just need to:

1. Assemble the source code with nasm:

nasm -f macho64 hello_world.asm

2. Link the resulting binary:

ld -macosx_version_min 10.7.0 -lSystem -o hello_world hello_world.o

3. Run:

./hello_world
