Question

我有一个hello-wrold项目：
main.cpp：

#include <iostream>
#include "square.h"
    int main() {
        int z = 5;
        std::cout << square(z) << std::endl;
        return 0;
    }

square.cpp：

int square(int x)
{
    return x * x;
}

square.h：

#ifndef SQUARE_H
#define SQUARE_H

int square(int x);

#endif //SQUARE_H

它可以从终端通过g ++编译并运行：

g++ -c main.cpp
g++ -c square.cpp
g++ main.o square.o -o programm
./programm
>25

但是CLion的构建最终以：

[ 50%] Linking CXX executable cpp_code
Undefined symbols for architecture x86_64:
  "square(int)", referenced from:
      _main in main.cpp.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[3]: *** [cpp_code] Error 1
make[2]: *** [CMakeFiles/cpp_code.dir/all] Error 2
make[1]: *** [CMakeFiles/cpp_code.dir/rule] Error 2
make: *** [cpp_code] Error 2

P.S。我曾经很长时间（虽然有很大的停顿）写了简单的c ++程序，但这是第一次，在这一步面临问题。另外，有一个CMakeList.txt自动创建的（在VisStud中没有类似的东西！） CMakeList.txt：

cmake_minimum_required(VERSION 3.12)
project(cpp_code)

set(CMAKE_CXX_STANDARD 14)

add_executable(cpp_code main.cpp)

square.cpp

无法在CLion中构建c ++项目
