Ardour is an application to fit the needs of musicians under Linux. It is designed to be a fully functional professional audio application, that uses the professional sound server jack for sound i/o. Ardour requires liblo, liblrdf, scons, libgnomecanvas, aubio, and jack-audio-connection-kit. If you want ardour with lv2 support pass LV2=yes to the script. This will additionally need lilv and suil. If you want support for controlling ardour via a wiimote device, you'll need to pass WIIMOTE=yes to the script. You need cwiid for that. For building ardour with support for VST-plugins, you have to pass VST=yes to the script. This will additionally require wine. Please note that VST-support will not be built on x86_64, regardless of the option passed.
