# Serving Mac Studio Native Packages from Debian 13 Trixie

## 🚀 **Cross-Compilation Build System**

Yes! You can absolutely serve Mac Studio native packages (.pkg) from a Debian 13 Trixie build system. This comprehensive guide shows you how to set up a complete cross-compilation pipeline.

## 📋 **Overview**

### **What We'll Build**
- **Native macOS .pkg packages** from Debian 13 Trixie
- **Universal binaries** (Intel + Apple Silicon)
- **Automated GitHub Actions** for CI/CD
- **Package distribution** via GitHub releases
- **One-click installation** for Mac users

### **Architecture**
```
Debian 13 Trixie (Build Server)
├── Cross-compilation tools
├── PyInstaller for standalone executables
├── macOS packaging tools (pkgbuild, productbuild)
└── GitHub Actions automation
    ↓
Native macOS .pkg packages
├── Universal binary support
├── Native performance
└── Zero dependencies on macOS
```

## 🛠️ **Setup on Debian 13 Trixie**

### **Step 1: Install Build Dependencies**

```bash
# Update system
sudo apt-get update && sudo apt-get upgrade -y

# Install basic build tools
sudo apt-get install -y \
    build-essential \
    python3.13 \
    python3.13-venv \
    python3.13-pip \
    python3.13-dev \
    python3-setuptools \
    python3-wheel \
    python3-cryptography

# Install macOS packaging tools
sudo apt-get install -y \
    xar \
    cpio \
    openssl \
    rsync \
    tar \
    gzip \
    curl \
    bc

# Install PyInstaller for standalone executables
python3.13 -m venv /opt/pyinstaller
source /opt/pyinstaller/bin/activate
pip install pyinstaller
```

### **Step 2: Create Build Environment**

```bash
# Clone repository
git clone https://github.com/aitbc/aitbc.git
cd aitbc

# Make build script executable
chmod +x packages/build-macos-packages.sh

# Run build
./packages/build-macos-packages.sh
```

## 🏗️ **Build Process**

### **What the Build Script Does**

#### **1. Environment Setup**
```bash
# Creates build directory structure
mkdir -p build-macos/{pkg-root,scripts,resources}

# Sets up package structure
mkdir -p pkg-root/usr/local/{bin,aitbc,share/man/man1,share/bash-completion/completions}
```

#### **2. CLI Build with PyInstaller**
```bash
# Creates standalone executable
pyinstaller aitbc.spec --clean --noconfirm

# Result: Single executable with no Python dependency
# Size: ~50MB compressed, ~150MB uncompressed
```

#### **3. macOS Package Creation**
```bash
# Build component package
pkgbuild \
    --root pkg-root \
    --identifier dev.aitbc.cli \
    --version 0.1.0 \
    --install-location /usr/local \
    --scripts scripts \
    --ownership recommended \
    AITBC\ CLI.pkg

# Create product archive
productbuild \
    --distribution distribution.dist \
    --package-path . \
    --resources resources \
    --version 0.1.0 \
    aitbc-cli-0.1.0.pkg
```

#### **4. Package Scripts**
- **preinstall**: System checks and directory creation
- **postinstall**: Symlinks, PATH setup, completion
- **preuninstall**: Process cleanup
- **postuninstall**: File removal
