node.js installation (Source: https://github.com/nodesource/distributions)
Notes: From October 27, 2023, the official installation method for node.js has changed, and the previous installation method is no longer supported. When building a new environment, please use the new installation method shown below. If you already have the same version (16.x) installed, you can continue using it.

#### 1. Download and import the Nodesource GPG key.
sudo apt update
sudo apt install -y ca-certificates curl gnupg
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg

#### 2. Create deb repository
NODE_MAJOR=16
echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_$NODE_MAJOR.x nodistro main" | sudo tee /etc/apt/sources.list.d/nodesource.list

#### 3. Run Update and Install
sudo apt update
sudo apt install nodejs -y

Installation from Source Compilation

Installation of HARK from source.
Compiling the source requires a compiler that supports at least C99 and C++11. Additionally, some additional features are implemented for compilers that support C++17 or higher. Please note that the compilers we support (and have tested) are GCC9 or later.
The following packages are needed to be installed:

libhark-netapi3
libharkio3
hark-base3
harkmw
hark-core
hark-linux
hark-gtkplot
python3-harkpython and hark-python3
harktool5
kaldidecoder-hark

To compile these packages, “libtool”, “cmake”, and “python3” are required.

Step0 : Preparation before the compilation

#### 0-1. Make your preferred directory to download source codes.
mkdir ${HOME}/YOUR_HARK_DOWNLOAD_DIR

#### 0-2. Install dependent packages.
sudo apt install build-essential gfortran libtool cmake pkgconf libxml2-dev libzip-dev libasound2-dev libsndfile1-dev libsdl2-dev libopenblas-dev liblapack-dev liblapacke-dev libeigen3-dev libfmt-dev libgtk2.0-dev libpopt-dev

sudo apt install mosquitto libmosquittopp-dev pybind11-dev python3-dev python3-daemon python3-paho-mqtt python3-pybind11 python3-pkgconfig python3-pip python3-setuptools python3-numpy python3-scipy python3-matplotlib python3-kivy

#### 0-3. Install the kivy_garden.graph package.
python3 -m pip install kivy_garden.graph --extra-index-url https://kivy-garden.github.io/simple/

The kivy_garden.graph is required to run the plot node in the hark-python3 package. If the kivy_garden.graph is not installed, only the plotting function will not work.
