Thread: undefined reference to class function

are you saying, I have to call play_move with members of cn_board?

If you will look in testing for cn_board, I call play_move with two literals, and it works fine, however, using two literals instead of variables in cn_board_node still gives an error

Code:

    temp->play_move(1, '0'); //both still give the same error
    temp->play_move(temp->get_height(), temp->get_width());

std: I am asking why my call to temp->play_move() doesn't work in cn_board_node, but is working fine in testing for cn_board
