Inside UIHandling.h:
enum eType{...};
class UIHandling : public exception
{
...
UIHandling(eType);
template <class T>
UIHandling(eType, T);
...
}
Inside another file CompaniesMap I call the second constructor many times using different enums and second variables of different types (double, unsigned int, eType, etc...)
I get the following errors:
1>CompaniesMap.obj : error LNK2019: unresolved external symbol "public: __thiscall UIHandling::UIHandling<double>(enum eType,double)" (??$?0N@UIHandling@@QAE@W4eType@@N@Z) referenced in function __catch$?addCompany@CompaniesMap@@UAEXXZ$2

Do I need to define the class itself to be a template? If so than why? If not, why do the errors appear?
