我正在尝试使用bess在Ubuntu中编译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。
整个项目的源代码位于：NetSys/bess in Github
但是，我运行.\build.py并遇到了一个令人沮丧的编译错误，如下所示：

错误显示error: ‘const class bess::Packet’ has no member named ‘refcnt’; did you mean ‘reset’?。我经过bess/core，找到了packet.cc和packet.h。实际上，我找不到refcnt()函数，并且uint16_t refcnt_;的私有字段中仅存在class Packet。
您能对我的问题发表一些看法吗？
最良好的祝愿。
