Hey all, I'm having a problem instantiating the UI of the parametric EQ by Nedko & Fons. ( http://nedko.arnaudov.name/soft/lv2fil/trac/wiki/WikiStart ) I can instantiate the Invada suite no problem. They have a http://lv2plug.in/ns/extensions/ui#GtkUI type UI & the host is also Gtk. instance = suil_instance_new( suilHost, 0, // pass a pointer to the controller objects here "http://lv2plug.in/ns/extensions/ui#GtkUI", // target UI widget type "http://nedko.aranaudov.org/soft/filter/2/mono", // plugin URI "http://nedko.aranaudov.org/soft/filter/2/gui", // plugin UI URI "http://lv2plug.in/ns/extensions/ui#external", // plugin UI TYPE URI "/usr/lib/lv2/filter.lv2/", // plugin UI bundle "/usr/lib/lv2/filter.lv2/filter.so", // plugin UI binary &featureArray[0]); // supported features by host // get widget of the UI instance SuilWidget widget = suil_instance_get_widget(instance); // add widget to container, casting "SuilWidget" to "GtkWidget*" as the target UI type is ui#GtkUI gtk_container_add (GTK_CONTAINER ( hbox->gobj() ), (GtkWidget*) widget); The error I get (at runtime) is the following: error: get_wrap_module: Unable to wrap UI type <http://lv2plug.in/ns/extensions/ui#external> as type <http://lv2plug.in/ns/extensions/ui#GtkUI> error: suil_instance_new: Failed to instantiate UI <http://nedko.aranaudov.org/soft/filter/2/gui> in /usr/lib/lv2/filter.lv2/filter.so Would anybody shed some light onto what I'm doing wrong?
