克++編譯錯誤（架構x86_64的未定義碼元）

Question

當我用g ++編譯代碼 - 4.9

g++ main.cpp base_server.cpp base_server.hpp threaded_server.cpp threaded_server.hpp 

我發現了錯誤：

Undefined symbols for architecture x86_64: 
    "BaseServer::~BaseServer()", referenced from: 
     ThreadedServer::~ThreadedServer() in ccQVIp8S.o 
     ThreadedServer::~ThreadedServer() in ccQVIp8S.o 
ld: symbol(s) not found for architecture x86_64 
collect2: error: ld returned 1 exit status 
make: *** [all] Error 1 

當我通過鐺編譯++沒有任何錯誤和警告。如何通過g ++編譯它？

BaseServer::~BaseServer()是inline。沒有inline全部正常工作。
