Intro

Hello, I'm trying to learn x86 assembly stuff, so this is the repo for it.

System

Its made for Windows using the Win32 library, so (this is a shocker) it wont work on Mac and Linux.

Compiling / Running

I havent figured out how to run it inside of vscode yet, so I have a 4 line command I use to compile and debug it.

nasm -F dwarf -g -f elf32 -o main.obj main.asm; nasm -F dwarf -g -f elf32 -o printing.obj printing.asm; ld main.obj printing.obj C:\Windows\SysWOW64\kernel32.dll -mi386pe --entry=_start -o main.exe; gdb -ex run .\main.exe

It can be seperated into 3 steps:

  1. Assembling the files:

     nasm -F dwarf -g -f elf32 -o main.obj main.asm;
 nasm -F dwarf -g -f elf32 -o printing.obj printing.asm;

  2. Linking them:

     ld main.obj printing.obj C:\Windows\SysWOW64\kernel32.dll -mi386pe --entry=_start -o main.exe;

  3. Debugging them

     gdb -ex run .\main.exe

Requirements

It requires nasm, msys2 (mingw), and gdb (comes in mingw)
