Question

我正试图重新使用C ++。因此，我决定按照一个教程系列进行学习。但是，我无法在CLion中编译以下代码。我想我在undefined reference to Class::Function() C++找到了一个修复程序，但并没有真正了解它的工作方式或如何避免它。我的代码如下：

Sally.cpp-C：\ Users \ bhave \ OneDrive \ Documents \ CLion Projects \ C ++ Tuts \ Sally.cpp

//
// Created by bhave on 4/18/2019.
//

#include "Sally.h"
#include <iostream>

using namespace std;

Sally::Sally(int a, int b) {
    regVar = a;
    constVar = b;
}

Sally.h-C：\ Users \ bhave \ OneDrive \ Documents \ CLion Projects \ C ++ Tuts \ Sally.h

//
// Created by bhave on 4/18/2019.
//

#ifndef C___TUTS_SALLY_H
#define C___TUTS_SALLY_H


class Sally {

public:
    Sally(int a, int b);
private:
    int regVar;
    const int constVar;
};


#endif //C___TUTS_SALLY_H

AllRun.cpp-C：\ Users \ bhave \ OneDrive \ Documents \ CLion Projects \ C ++ Tuts \ All run.cpp

//
// Created by bhave on 4/6/2019.
//

#include <iostream>
#include "Important Tutorial Files/RandNumGen.h"
#include "Important Tutorial Files/Default Value Functions.cpp"
#include "Important Tutorial Files/Tutorial 29.cpp"
#include "Sally.h"

using namespace std;

// Default Value Function
void fn0() {
    cout << volume() << endl;
    cout << volume(10) << endl;
    cout << volume(10, 4) << endl;
    cout << volume(10, 4, 8) << endl;
}

// Random Number Generator Example
void fn1() {
    cout << RandNumGen::genRand() << endl;
    cout << RandNumGen::genRangeRand(1, 6) << endl;
}

int main() {
    Sally sally(23, 42);
    fn0();
    fn1();
    return 0;
}

CMakeLists.txt-C：\ Users \ bhave \ OneDrive \ Documents \ CLion Projects \ C ++ Tuts \ CMakeLists.txt

cmake_minimum_required(VERSION 3.13)
project(C___Tuts)

set(CMAKE_CXX_STANDARD 14)

add_executable(C___Tuts "All run.cpp")

编辑：我认为这是一个链接器错误，但是我以前从未遇到过，所以如果有人可以解释在创建文件时如何在CLion中避免它，那将是很好的事情。
