这是奇怪的。当我把一 file(Search.h)列入档案时,我怎么会遇到错误,但是,当我列入文件(Search.cpp)时,似乎一切都只是罚款?

#ifndef GENERALSEARCH_H_
#define GENERALSEARCH_H_

#include "Problem.h"
#include "Node.h"

template <class T>
class GeneralSearch
{

    const Node* treeSearch(const Problem &problem) const;
    const Node* graphSearch(const Problem &problem, T &fringe = T()) const;

private:
    void expand(const Node &node, const Problem &problem, list<const Node*> &out) const;
};
