Note: For up to date information of the installation process please refer to the README file coming with the source.

The easiest way to use the plugin is to use the pre-compiled shared library coming with the package. This requires you to have the Qt runtime libraries installed (version >3.2 for Linux, version 2.3.0 Non Commercial for Windows). To make the plugin available to your browser you need the following:

  • Pure Data (

  • streaming external (

  • xmlrpc external (

You need to set up Pd properly, with both externals working (streaming, xmlrpc). They need to specified to be loaded in the script invoking pd with "-lib xmlrpc" and "-lib streaming"

  • Download the Package iARS.tar.gz ( for Windows)

  • unpack

  • copy (npiARS.dll) into your plugin directory (e.g. ~/.mozilla/plugins or C:\Programms\\Mozilla\plugins\)

  • Set the following in your config file (an example is included)

    PD_EXEC = /path/to/pd-startup-script
    PD_XMLRPC_INIT = /path/to/the/xmlrpc-init.pd
    PD_HOST = HostOfXmlRpcServer
    PD_PORT	= PortOfXmlRpcServer
    The last two must be the same as specified in the xmlrpc-init.pd file (ditributed with the xmlrpc external)!! (by default localhost - 8888)

The plugin will look for your config file in your home directory ($HOME/.iARS/iARS.conf on LINUX and HOMEPATH\iARS\iARS.conf for Windows) first and for UNIX also in the system /etc/iARS.conf.

Test your installation by examining "About Plugins" and by the test pages at the IAEM portal (

To be able to take advantage of the EXTRAS feature you must have "unzip" installed and available in your path. This allows you to use patches which come with an additional "" file in which extra externals and abstraction-patches can be provided. (unzip is available from:

Note: EXTRAS are currently not available for Windows



To compile this plugin you will need to get the following:

  • Pure Data (

  • streaming external (

  • xmlrpc external (

  • QT (>3.2) Unix (QT 2.3.0 Non Commercial for Windows

  • Netscape Plugin SDK

  • XmlRpc++ (> 0.7)

  • gcc (> 3.x) (Microsoft cl compiler > 12.0 - MS Studio > 6.0)


Compile QT and build the nsplugin extension of the library. Follow these instructions and examine the examples to make sure the library is working.


Download the code from the homepage and build it according the instructions found in the README file there.

iARS Shared Library

After unpacking edit the file to reflect your paths to the XMLPRC and QT libraries and include files. After that type:

UNIX: qmake; make

WINDOWS: tmake -o Makefile; (Edit the Makefile according to te notes in!) -> nmake;

Pure Data

Build Pure Data as described in the approperiate INSTALL file. The two externals need to be copied to locations where pd finds it without the necissity of providing the full path name (e.g. the default external dir).

Installation of the plugin

If everything went fine you have a library called "" ("npiARS.dll" on Windows) in this directory. COPY it to a directory where your browser looks for plugins and check whether the browser recognises it by opening the Help->About Plugins page. If the plugin is listed there everything everything went right so far.

You need to edit your config file as stated above.
