无法解析的外部符号链接列表实现与模板C++

因此，从.csv文件我创建用户，这是从用户类。我试图创建一个链表，它将包含所有的用户，但我得到一个错误插入到链接列表中，顺便提一句名为“ListaLigada”。我无法自己弄清楚。无法解析的外部符号链接列表实现与模板C++

所以，这就是我得到：

错误1个错误LNK2019：无法解析的外部符号 “市民：无效 __thiscall ListaLigada ::插入（类用户）”（插入@ $ ListaLigada？ @VUser @@@@ QAEXVUser @@@ Z）功能 “void __cdecl genUserLList（class ListaLigada &）” （？genUserLList @@ YAXAAV？$ ListaLigada @ VUser @@@@@ Z）C：\ Users \ Daniel \ documents \ visual studio 2010 \ Projects \ Radio Station \ Radio Station \ Auxf.obj Radio Station

如果你能确定我做错了什么，我会成为你的朋友，现在已经很长时间了。
