Sounds like your add-on is missing the instantiation function, which should be declared as extern "C" BMediaAddon* make_media_addon(image_id imageID) and return an instance of the add-on as documented at: http://www.haiku-os.org/legacy-docs/bebook/BMediaAddOn.html#BMediaAddOn_GlobalFunctions Regards, Rene
