OSPP (OS++)

Overview

OSPP (OS++) is a hobbyist kernel project designed to explore low-level system programming using C++17. Built for x86 architectures, it implements a modular monolithic kernel with core functionalities like memory management, interrupt handling, and task scheduling. The project leverages C++'s type safety and abstractions to create a clean, extensible system, debugged and tested on both emulators (QEMU, Bochs) and real hardware.

Build Requirements

For Debian-based systems, install the following packages:

sudo apt -y install qemu qemu-system gcc g++ binutils make cmake grub-pc

Build and Run Instructions

1. Initialize Disk Image (creates a 32MB disk image with ext2 filesystem and GRUB):

   ./utils.sh init

2. Build and Pack Kernel:

   ./utils.sh pack [Debug|Release]

3. Run Options:

   • QEMU: ./utils.sh run
   • QEMU with KVM: ./utils.sh runk
   • Bochs: ./utils.sh runb
   • Debug with GDB: ./utils.sh rund

4. Manual Build:

   cmake -B build . -DCMAKE_BUILD_TYPE=Debug
   make -C build -j$(nproc)

   Binaries are output to the output/ directory.
