So, from a .csv file i'm creating users, which is from the class User. I'm trying to create a linkedlist, that will contain all users, but i'm getting an error inserting them into the linkedlist wich, by the way is named "ListaLigada". I can't figure it out by myself.
so, this is what i'm getting:
Error 1 error LNK2019: unresolved external symbol "public: void __thiscall ListaLigada::insert(class User)" (?insert@?$ListaLigada@VUser@@@@QAEXVUser@@@Z) referenced in function "void __cdecl genUserLList(class ListaLigada &)" (?genUserLList@@YAXAAV?$ListaLigada@VUser@@@@@Z) C:\Users\Daniel\documents\visual studio 2010\Projects\Radio Station\Radio Station\Auxf.obj Radio Station
If you can identify what i'm doing wrong i'll be gratefull, it has been long 2 days by now.
Here's the code that is related:

Thanks in advance. I don't know what to do anymore... I'm reading the users
