Setup

VILLASnode can be installed in multiple ways:

  • Using a pre-build Docker image
  • Using pre-build RPM packages for Redhat based Linux distributions
  • or from source

Prerequisites

VILLASnode currently has the following list of dependencies:

  • libconfig for parsing the configuration file.
  • libnl3 for the network communication & emulation support of the socket node-type.
  • libOpal{AsyncApi,Core,Utils} for running VILLASnode as an Asynchronous process inside your RT-LAB model.
  • libjansson JSON parser for websocket and ngsi node-types.
  • libwebsockets for the websocket node-type.
  • libcurl for HTTP REST requests by the ngsi node-type.
  • openssl

There are two ways to install these dependencies:

  1. You can most of the dependencies using the package manger of your Linux distribution:

Use the following command to install the dependencies under Debian-based distributions:

$ sudo apt-get install build-essential pkg-config wget tar cmake doxygen dia graphviz libconfig-dev libnl-3-dev libnl-route-3-dev libjansson-dev libcurl4-openssl-dev

or the following line for Fedora / CentOS / Redhat systems:

$ sudo yum install gcc pkgconfig make wget tar cmake openssl-devel doxygen dia graphviz libconfig-devel libnl3-devel libcurl-devel jansson-devel
  1. Alternatively, you can use the build system to download, compile and install all dependencies:
$ make install-thirdparty

Downloading VILLASnode

$ git clone --recursive git@git.rwth-aachen.de:VILLASframework/VILLASnode.git
$ cd VILLASnode

Compilation

Checkout the Makefile and include/config.h for some options which have to be specified at compile time.

Afterwards, start the compilation with:

$ make
$ make run-tests

Append V=5 to make for a more verbose debugging output. Append DEBUG=1 to make to add debug symbols.

Installation

Install the files to your search path:

$ make install
$ make install-doc

Append PREFIX=/opt/local to change the installation destination.

Test

Verify everything is working and required node-types are compiled-in:

$ villas node --help

Will print the current version including a list of all supported node-types, hooks, etc.
