Start with the ./run_server output and inspect run_server.cpp, http_server.cpp, dict_manager.cpp, and utils.cpp around the reported initialization errors. Check how ./example/conf/wordseg_utf8 is expected to be provided or located, then reproduce the server startup failure. Done means the example server initializes successfully without the lac dictionary load error.
