[ndnSIM] error: using typedef-name ‘ndn::nfd::LocalControlHeader’ after ‘class’

[Carl Zu]

Hi everyone,

the two lines below are the last lines from the definition of the interest
class:

 nfd::LocalControlHeader m_localControlHeader;
  friend class nfd::LocalControlHeader;

But they cause the errors below for me. Can anybody give me some guidance
please.

Thanks in advance and regards.
