I have included declaration below

#include "ns3/log.h"
#include "ns3/ndnSIM/NFD/common.hpp"
#include "ns3/ndnSIM/NFD/core/logger.hpp"

But when I tried to compile a cpp file including sentence NS_LOG_FUNCTION(this
<< &interest), I met the following problem. Kindly, please let me know if
you have some thoughts

../src/ndnSIM/model/ndn-net-device-link-service.cpp:60:3: error: use of
undeclared identifier 'g_log'
./ns3/log-macros-enabled.h:219:11: note: expanded from macro
'NS_LOG_FUNCTION'
          NS_LOG_APPEND_TIME_PREFIX;                            \
          ^
./ns3/log-macros-enabled.h:40:7: note: expanded from macro
'NS_LOG_APPEND_TIME_PREFIX'
  if (g_log.IsEnabled (ns3::LOG_PREFIX_TIME))                   \
      ^
