My 64-bit OS!

🔴 This code is not all written by me. Most of it was written following this tutorial by CodePulse on Youtube, as well as following the OSdev wiki

Setup

Build an image for the build-environment: docker build buildenv -t x64-os

(If you're having issues with apt, run the above command with --network host)

Build

Enter build environment:

• Linux or MacOS: docker run --rm -it -v "$pwd":/root/env x64-os
• Windows (CMD): docker run --rm -it -v "%cd%":/root/env x64-os
• Windows (PowerShell): docker run --rm -it -v "${pwd}:/root/env" x64-os
• NOTE: If you are having trouble with an unshared drive, ensure your docker daemon has access to the drive you're development environment is in. For Docker Desktop, this is in "Settings > Shared Drives" or "Settings > Resources > File Sharing".

Build for x86 (other architectures may come in the future):

• make build-x86_64

To leave the build environment, enter exit.

Emulate

You can emulate your operating system using Qemu:

• qemu-system-x86_64 -cdrom dist/x86_64/kernel.iso
• NOTE: When building your operating system, if changes to your code fail to compile, ensure your QEMU emulator has been closed, as this will block writing to kernel.iso.

Alternatively, you should be able to load the operating system on a USB drive and boot into it when you turn on your computer.

Cleanup

Remove the build-evironment image:

• docker rmi x64-os -f
