Database Module

A comprehensive database abstraction layer with:

• Connection management
• CRUD operations (insert, update, delete, select)
• Transaction support (begin, commit, rollback)
• Error handling

Building the Application

make              # Build the application
make run          # Build and run
make clean        # Clean build artifacts

CubeCactusOS

A microkernel-based operating system inspired by MINIX3, featuring:

• Microkernel architecture with message-passing IPC
• Process Manager (PM) server
• Virtual File System (VFS) server
• TTY driver for terminal I/O
• Modular, fault-isolated design

OS Development

# View OS documentation
cat os/README.md
cat os/SETUP.md

# Run setup script
./os/setup.sh

# Build OS components (development)
make -f Makefile.os os-build

# For complete bootable OS, follow os/SETUP.md

OS Architecture

CubeCactusOS follows MINIX3's microkernel design:

• Microkernel: Minimal kernel (IPC, scheduling, low-level operations)
• System Servers: User-space processes (PM, VFS, etc.)
• Device Drivers: Isolated driver processes
• Message Passing: IPC-based communication

Prerequisites

For Application Development

• g++ compiler (C++17 or later)
• make

For OS Development

• GCC/Clang toolchain
• QEMU (for testing)
• GRUB (for bootable images)
• Git (to clone MINIX3 source)

See os/SETUP.md for detailed OS build prerequisites.

Quick Start

Application

make run

Operating System

./os/setup.sh          # Check prerequisites
cat os/SETUP.md        # Read complete guide
