我正在为一个学校项目编写一个模拟共享编辑器（如 Google Docs）的小程序

我已经编写了我需要的所有类，但是当我尝试构建程序时，我得到了这个错误：

error: unknown type name 'NetworkServer' NetworkServer &_server;

error: use of undeclared identifier 'SharedEditor' std::vector<SharedEditor*> SEditors;

error: expected expression std::vector<SharedEditor*> SEditors;

error: unknown type name 'SharedEditor' int connect(SharedEditor* sharedEditor);

这是我的 .h 文件

网络服务器.h

#include <vector>
#include <queue>

#include "SharedEditor.h"
#include "Message.h"


class NetworkServer {                               
private:
    std::vector<SharedEditor*> SEditors;
    std::vector<int> idEditors;
    std::queue<Message> messages;

public:
    int connect(SharedEditor* sharedEditor);
    int disconnect(SharedEditor* sharedEditor);

    void send(const Message& m);
    void dispatchMessages();
};

共享编辑器.h

#include "NetworkServer.h"
#include "Message.h"
#include "Symbol.h"

class SharedEditor {
private:
    NetworkServer& _server;
    int _siteId{};
    std::vector<Symbol> _symbols;
    int _counter;

public:
    SharedEditor() = delete;
    SharedEditor(NetworkServer& server);

    void localInsert(int index, char value);
    void localErase(int index);

    void process(const Message& m);
    std::string to_string();

    int getSiteId() const;

};

符号.h

#include <vector>

class Symbol {
private:
    char value;
    int idClient;
    int num;
    std::vector<int> pos;

public:
    Symbol(char value, int client, int num, std::vector<int> pos);

    char getValue() const;
    int getIdClient() const;
    int getNum() const;
    const std::vector<int> &getPos() const;

};

消息.h

#include <vector>

class Message {
    bool insert;           // true --> insert || false --> delete
    int _siteId;
    int num;
    char value{};
    std::vector<int> pos;

public:
    Message(bool insert, int siteId, int num, char value, std::vector<int> pos);
    Message(bool insert, int siteId, int num);

    bool isInsert() const;
    int getSiteId() const;
    int getNum() const;
    char getValue() const;
    const std::vector<int> &getPos() const;
};

我不明白我在哪里做错了。顺便说一句，我正在使用 CLion
