A Bare-Metal 80386 program in Cowgol

This is the https://wiki.osdev.org/Bare_Bones tutorial, in the Cowgol language. It represents the capabilities of the language and its toolchain as of commit ec33ae1. It consists of two main files:

• boot.cow: A small program that prints a Hello World message two different ways. Take a look at this program to see how Cowgol differs from C.
• archgrub386.coh A Cowgol header file. It describes a linker that turns Cowgol object files into GRUB multiboot images that can be loaded by GRUB or programs compatible with it, like QEMU.

Dependencies

• A Linux environment.
• Cowgol and all of its dependencies.
• QEMU, if you want to run the final image in an emulator.

Instructions

These instructions should be accurate as of commit ec33ae1.

1. Clone Cowgol and this repository so that they sit side-by-side in the same directory.
2. Add archgrub386.coh to the directory cowgol/src/cowlink.
3. In cowgol/src/cowlink, there should be a file named build.py. Make it recognize archgrub386.coh. I leave the exact method up to you, so that you get familiar with the Cowgol toolchain.
4. Build Cowgol.
5. Go back to cowgol_bare_bones. Run make to compile, assemble, and link boot.cow.
6. Run make run to launch the final project in QEMU.

Dedication

This project is derivative of two sources, The OSDev Wiki and the Cowgol compiler. It only makes sense to release it under the same terms as the Cowgol compiler itself.
