У меня есть рабочая сборка buildroot (2017.02.1). Мне нужно добавить mDNS. Используя меню конфигурации, мне удалось добавить и построить первую опцию автоматического IP-адреса avahi. Когда я добавляю дополнительные параметры mDNS и libdns_sd, сборка завершается с ошибкой (ниже). Я удалил «dbus» из «fs_skeleton/etc/passwd», но сборка по-прежнему не работает. Я новичок в buildroot, поэтому любые указатели помогут!
