Comment 1 Peter Barnes 2019-11-05 16:56:28 EST

Linker error message was 

debug/libns3-DisService.so: undefined reference to
`ns3::WorldState::Unref() const'

Caused by 

#include "foo.h"

instead of 

#include "ns3/foo.h"

Suggestion was to document this better in the Creating a new ns-3 model chapter of the Manual:
