Xcode 错误"not found for architecture" 。尝试不使用库的基本C++

Xcode error "not found for architecture". trying basic C++ w/o libraries

本文关键字：C++ found not 错误 for architecture Xcode      更新时间：2023-10-16

我看到了很多关于这个"not found for architecture"的错误，但我还没有从阅读其他一些帖子中找到解决方案…(在我看来，他们大多数都专注于库链接，但我不认为我在使用任何库…)

我正在尝试做非常基本的c++东西，基本上只是传递一个对象到另一个类中的另一个函数。我是c++的初学者，主要来自Java，所以我甚至不完全确定是我写错了代码还是IDE的问题…

我的代码:

class One{
public:
    One();
    int value;
};
One::One(){
    value = 5;
}

class Two{
public:
    Two();
    One one;
    int doSomething(One* oneArgument);
    int somethingThatCallsDoSomething();
};
int Two::doSomething(One *oneArgument){
    return oneArgument->value;
}
int Two::somethingThatCallsDoSomething(){
    doSomething(&one);
    return 0;
}

int main(){
    Two two;
    return two.somethingThatCallsDoSomething();
}

我的错误是，我得到一个'构建失败'与两个错误:

架构x86_64的未定义符号:"Two::Two()"，引用自:_main in main. 0没有找到架构x86_64的Ld:符号Clang:错误:链接器命令失败，退出代码为1(使用-v查看调用)

这是上面的附加文本(我不知道它是关于什么的…):

我从2012年11月开始在Macbook Pro视网膜显示器13"上运行Xcode 5.1.1

这个问题是非常令人沮丧的b/c我甚至不能通过基本的编程的东西进步…

非常感谢你的帮助!

您省略了类2默认构造函数。您可以将它添加到类定义

class Two{
public:
    Two() {}
    One one;
    int doSomething(One* oneArgument);
    int somethingThatCallsDoSomething();
};

或其他地方(像你的其他方法)

Two::Two(){
   //Some constructor code here
}
