Ошибка компиляции при компиляции NetSys / bess с использованием `build.py`

Question

Я пытаюсь скомпилировать bess в моем Ubuntu с Linux localhost 4.13.0-16-generic #19-Ubuntu SMP Wed Oct 11 18:35:14 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux.

Исходный код всего проекта находится по адресу: NetSys / bess в Github

Тем не менее, я запустил .\build.py и получил разочарованную ошибку компиляции следующим образом:

Ошибка говорит error: ‘const class bess::Packet’ has no member named ‘refcnt’; did you mean ‘reset’?.Я прохожу через bess/core и нахожу packet.cc и packet.h.На самом деле, я не нахожу функцию refcnt(), и только uint16_t refcnt_; существует в личных полях class Packet.

Не могли бы вы поделиться мнением по моей проблеме?

С наилучшими пожеланиями.
