NS-3: undefined reference to `ns3::AnimationInterface::AnimationInterface
Suppose you're modifying code in `ns-3/examples/` Locate `CMakeLists.txt` of your example code; e.g. mine's locate at `ns-3/examples/tcp/CMakeLists.txt`. Add ` ${libnetanim} ` to LIBRARIES_TO_LINK. build_example( NAME tcp-star-server SOURCE_FILES tcp-star-server.cc LIBRARIES_TO_LINK ${libpoint-to-point} ${libapplications} ${libinternet} ) becomes build_example( NAME tcp-large-transfer SOURCE_FILES tcp-large-transfer.cc LIBRARIES_TO_LINK ${libpoint-to-point} ${libapplications} ${libinternet} ${libnetanim} ) Old document only says `Add 'netanim' to your wscript`. This is how you solve it.
