конструктор — c ++ неопределенная ссылка на `vtable

Мой вопрос изменился по сравнению с другим, который я опубликовал. Я начал с нескольких файлов и решил поместить все это в один файл main.cpp, чтобы заставить его работать.

main.cpp:

#include <iostream>

virtual void insertEnd(int insertItem) = 0;
void removeAt(int location);

void clearList();
virtual int seqSearch(int searchItem) const  = 0;
