架构x86_64: party::getArrival()的未定义符号

Undefined symbols for architecture x86_64: party::getArrival()

本文关键字：未定义 符号 party x86 架构 getArrival      更新时间：2023-10-16

我有一个名为party.h的party类的头文件:

#ifndef party_h
#define party_h
#include <iostream>
class party{
private:
    int people;
    int waitTime;
    bool waiting;
    int arrival;
public:
    party();
    party(int, int);
    int getPeople();
    void setPeople(int);
    bool isWaiting();
    void setWaiting(bool);
    void setWaitTime(int);
    int getwaitTime();
    void setArrival(int);
    int getArrival();
    int getTotalTime(int);
    void decrement();
};
#endif

及其在party.cpp中的实现:

#include "party.h"
party::party(){}
party::party(int numPeople, int a){
    people = numPeople;
    arrival = a;
}
int party::getPeople(){
    return people;
}
void party::setPeople(int p){
    people = p;
}
bool party::isWaiting(){
    return waiting;
}
void party::setWaiting(bool w){
    waiting = w;
}
void party::setWaitTime(int t){
        waitTime = t;
}
int party::getwaitTime(){
    return waitTime;
}
void party::setArrival(int a){
    arrival =a; 
}
int party::getTotalTime(int current){
    return (current-arrival);
}

每当我构建项目时，我都会得到下面的错误消息，

这是一个新的错误信息，因为它在今天早些时候/这个周末在visual studio中工作。但从那以后，我已经修改了相当数量的代码，要点中的代码已经更新，这就是我正在使用的代码。我目前正试图让它在xcode中构建，这样我就可以完成调试/编程我的项目，这是今晚到期。任何帮助都非常感谢!谢谢!

您没有在party.cpp文件中定义getArrival。您可能需要:

int party::getArrival(){
    return arrival;
}
