Unity Chess Stockfi sh Android ошибка при звонке

Question

В Unity я пытаюсь вызвать шахматный движок stockfi sh (stockfi sh -10-armv7) из android, но получаю сообщение об ошибке (mono-io-layer-error (5)) при выполнении новый процесс во время выполнения. Сборка P C работала нормально. Движок необходимо запускать как отдельный процесс, а обмен данными осуществляется через поток ввода-вывода. Кто-нибудь знает, что это за ошибка mono-io-layer (5)? ​​
