What are all these errors about? - c++

Question

I hate copypasting the whole log here but I can't understand what these errors mean...
I understand some of them have to do with the way I'm using the unique_ptr, but since my IDE doesn't directly point out the incriminated lines I don't know what to do.

This is Tab.h:
class Tab {

~Tab();
void addColumn(string name, string type);
void addRecord(string column);
void operator=(const Tab& to_assign);
private:
map<string, unique_ptr<Column>> _columns;
int _primary_key;
};
And these are two methods:
void Tab::addColumn(string name, string type) {
// I switch all the different types and create a new element on the columns map
// depending on what is the result
switch(Type2Int(type)) {
case OptionInt:
_columns[name].reset(new IntColumn());
break;
case OptionFloat:
_columns[name].reset(new FloatColumn());
break;
case OptionChar:
_columns[name].reset(new CharColumn());
break;
case OptionText:
_columns[name].reset(new TextColumn());
break;
case OptionTime:
_columns[name].reset(new TimeColumn());
break;
case OptionDate:

}
}
void Tab::operator=(const Tab &to_assign) {
_columns = to_assign._columns;

ColumnImpl class:
template <typename T> class ColumnImpl : public Column {
public:

ColumnImpl(const T& to_set);
vector<T> const& getData() const { return _data; }
void addElem(const T& elem_to_add);
void operator=(const ColumnImpl& to_assign);

And this is a supsect method:
template<typename T>
void ColumnImpl<T>::operator=(const ColumnImpl &to_assign) {
_data = to_assign._data;
}
Database.h:

public:
Database();
~Database();
void createNewTable(string name);
void addColumnToTab(string tab_name, string col_name, string type);

These are the only two methods I've implemented:
void Database::createNewTable(string name) {

}
void Database::addColumnToTab(string tab_name, string col_name, string type) {
const auto & it_target_tab = _tables.find(tab_name);

}
