🛠️ Manual Installation

Step 1: System Dependencies

🐧 Ubuntu/Debian

sudo apt-get update && sudo apt-get install -y \
    build-essential cmake git wget curl pkg-config \
    libboost-all-dev libssl-dev nlohmann-json3-dev \
    libwebsocketpp-dev python3 python3-pip python3-venv

🍎 macOS

brew install cmake boost openssl nlohmann-json websocketpp python3

Step 2: ONNX Runtime Setup

# Download and install ONNX Runtime
wget https://github.com/microsoft/onnxruntime/releases/download/v1.16.3/onnxruntime-linux-x64-1.16.3.tgz
tar -xzf onnxruntime-linux-x64-1.16.3.tgz
sudo cp -r onnxruntime-linux-x64-1.16.3/include/* /usr/local/include/
sudo cp -r onnxruntime-linux-x64-1.16.3/lib/* /usr/local/lib/
sudo ldconfig

Step 3: Python Environment

# Create and activate virtual environment
python3 -m venv venv && source venv/bin/activate

# Install ML dependencies
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cpu
pip install numpy pandas scikit-learn onnx onnxruntime joblib matplotlib seaborn

Step 4: Build & Deploy

# Train ML models
source venv/bin/activate && python scripts/export_models_to_onnx.py

# Build C++ engine
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release && make -j$(nproc)

# 🎉 Launch the engine
./quantx_engine

🛠️ Troubleshooting

🔨 Build Issues

# Missing ONNX Runtime
export CMAKE_PREFIX_PATH=/usr/local:$CMAKE_PREFIX_PATH

# Boost libraries not found
sudo apt-get install libboost-all-dev

# WebSocket++ headers missing
sudo apt-get install libwebsocketpp-dev

🚨 Runtime Errors

# Market data connection failed
# → Check API keys in config/config.json

# ONNX model not found
# → Run: python scripts/export_models_to_onnx.py

# Permission denied
# → Run: chmod +x scripts/*.sh

⚡ Performance Issues

# Enable CPU performance mode
echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

# Increase network buffer sizes
echo 'net.core.rmem_max = 134217728' | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
