error LNK2001: unresolved external symbol 求助

编译时出现错误如下，可能是什么原因？我用的vs2008编译的。库明明引用了，但还报错.

1>libprotobuf.lib(message.obj) : error LNK2001: unresolved external symbol "__declspec(dllimport) public: void __thiscall std::_Container_base_secure::_Orphan_all(void)const " (__imp_?_Orphan_all@_Container_base_secure@std@@QBEXXZ)
