The problem is here: clarity_cover.c: In function 'clarity_cover_set_album_item':
clarity_cover.c:244:9: error: format not a string literal and no format arguments [-Werror=format-security] I fixed the problem like this: gtkpod-2.1.2/plugins/clarity/clarity_cover.c // Set cover artwork gtk_clutter_texture_set_from_pixbuf (GTK_CLUTTER_TEXTURE(priv->texture), item->albumart, &error); if (error) { + g_warning("%s", error->message); - g_warning(error->message); g_error_free(error); return; } After the fix gtkpod compiled.
