VS code中编写C++的头文件无法使用是什么原因？

Question

工作区没有检测到错误

终端显示信息如下：

> Executing task in folder Codes: D:\MinGW\bin\g++.exe -g c:\Users\lenovo\Documents\Codes\exp9\9-2\main.cpp -o main.exe <

d:/mingw/bin/../lib/gcc/mingw32/8.2.0/../../../../mingw32/bin/ld.exe: C:\Users\lenovo\AppData\Local\Temp\ccv0rkaB.o: in function `main':

c:/Users/lenovo/Documents/Codes/exp9/9-2/main.cpp:9: undefined reference to `Stack::Stack(int)'

d:/mingw/bin/../lib/gcc/mingw32/8.2.0/../../../../mingw32/bin/ld.exe: c:/Users/lenovo/Documents/Codes/exp9/9-2/main.cpp:9: undefined reference to `Stack::~Stack()'

collect2.exe: error: ld returned 1 exit status

终端进程已终止，退出代码: 1

终端将被任务重用，按任意键关闭。

Answer 2

你这里显示的是链接错误，stack 没有被编译链接。你看看有关的工程、任务什么的哪里没设置好吧...

  终端被任务重用是正常情况，检查以下：tasks.json launch.json有没有配置好，一般是这种情况mingw 有没有安装好目录有无读写权限是否存在C盘建议把文件存在D盘内，再试一下。
