VSCode debug 问题记录

问题一

项目场景：

debug时无法调试断点，断点信息提示信息如下：
Module containing this breakpoint has not yet loaded or the breakpoint address not be obtained
调试代码如下
statepattern
文件目录如下图
.├── main
├── MusicPlayer.cpp
├── MusicPlayer.h
├── MusicPlayerState.cpp
├── MusicPlayerState.h
├── MusicPlayerTest.cpp
├── PausedState.cpp
├── PausedState.h
├── PlayingState.cpp
├── PlayingState.h
├── README.md
├── StoppedState.cpp
└── StoppedState.h

问题描述：

# 原因分析：

手动编译程序时，编译语句没有写对少写了一个-g
g++ ./MusicPlayerTest.cpp ./MusicPlayer.cpp ./MusicPlayerState.cpp ./PausedState.cpp ./StoppedState.cpp ./PlayingState.cpp -o main

---

解决方案：

g++ -g ./MusicPlayerTest.cpp ./MusicPlayer.cpp ./MusicPlayerState.cpp ./PausedState.cpp ./StoppedState.cpp ./PlayingState.cpp -o main。

通过修改，程序能够顺利进入断点进行运行

问题二

项目场景：

tasks.json
launch.json 文件配置，能够实现编译以及调试功能
参考文档如下：

文件目录如下图 (已经将上面的文件结构进行更改)

问题描述：

文档debug时老是出错，编译通不过，只能进行调试，

原因分析：

解决方案：

关键点如下，多路径编写，头文件路径
“args”: [
“-g”,
“$fileDirname/\ast \ast .cpp","${fileDirname}/src/**.cpp”,
“-I$workspaceFolder/src","-o","${workspaceFolder}/main”
],
