Question

我知道之前已经提出这个问题，但我无法弄清楚我的计划有什么问题。

我有一个类和一个头文件：

State.cpp

    #include "State.h"
#include "GameObject.h"
#include <iostream>
#include <iomanip>
#include <memory>
#include <iterator>
#include <vector>
#include "wordwrap.h"




using std::string;
using std::unique_ptr;
using namespace std;
using std::list;

/**
 * Current state of the game.
 */

/**
 * Display the description of the room the player is in. */

void State::announceLoc() const {
    this->currentRoom->describe();
}

/**
 * Constructor.
 * @param startRoom Pointer to the room to start in.
 */
State::State(const Room *startRoom) : currentRoom(startRoom) {};

/**
 * Move to a specified room and print its description.
 * @param target Pointer to the room to move to.
 */
void State::goTo(const Room *target) {
    this->currentRoom = target;
    this->announceLoc();
}

GameObject State::addToInv(GameObject* gameobject) {
    Inventory.push_back(gameobject);
}

void State::dispInv(){

    for (auto test : Inventory){
        wrapOut(test->getName());
        wrapEndPara();
    }
}


/**
 * Return a pointer to the current room.
 * @return Pointer to the current room.
 */
const Room* State::getCurrentRoom() const {
    return this->currentRoom;
}

和State.h

#ifndef TEXTADV_STATE_H
#define TEXTADV_STATE_H


#include "Room.h"
#include "GameObject.h"
#include <list>
using std::string;

using namespace std;
using std::list;


class State {
    const Room *currentRoom;
    static list<GameObject*> Inventory;

public:
    GameObject addToInv(GameObject* gameobject);
    void dispInv();
    explicit State(const Room *startRoom);
    void goTo(const Room *target);
    void announceLoc() const;
    const Room* getCurrentRoom() const;

};

然而，当我尝试运行它时，我遇到了问题：

CMakeFiles \ ott.dir / objects.a（State.cpp.obj）：在函数中 ZN5State8addToInvEP10GameObject': H:/.0 Year 3/C and C++/CW/ott/State.cpp:49: undefined reference to国家::库存[ABI：cxx11]＆＃39; CMakeFiles \ ott.dir / objects.a（State.cpp.obj）：在函数中 ZN5State7dispInvEv': H:/.0 Year 3/C and C++/CW/ott/State.cpp:54: undefined reference to国家::库存[ABI：cxx11]＆＃39; collect2.exe：错误：ld返回1退出状态mingw32-make.exe [3]： * [ott.exe]错误1 mingw32-make.exe [2]： [CMakeFiles / ott.dir / all]错误2 CMakeFiles \ ott.dir \ build.make：225：目标＆＃39; ott.exe＆＃39;的配方失败的CMakeFiles \ Makefile2：66：目标的配方＆＃39; CMakeFiles / ott.dir /所有＆＃39;失败的CMakeFiles \ Makefile2：78：食谱对于目标＆＃39; CMakeFiles / ott.dir / rule＆＃39; mingw32-make.exe失败[1]： [CMakeFiles / ott.dir / rule]错误2 Makefile：117：目标配方＆＃39; ott＆＃39; mingw32-make.exe失败：* [ott]错误2

我做错了什么，如何解决这个问题？

未定义的引用`State :: Inventory [abi：cxx11]＆＃39;
