# gcc
|
||
|
||
> 当前会这一种调试就行了。cmake编译构建工具以后再学。msvc编译构建工具为啥不直接使用vscode呢。
|
||
|
||
|
||
## 1 条件
|
||
|
||
* vscode
|
||
* MinGW-gcc/g++
|
||
* addon-C/C++
|
||
|
||
## 2 创建helloworld
|
||
|
||
```C
|
||
#include <iostream>
|
||
#include <vector>
|
||
#include <string>
|
||
|
||
using namespace std;
|
||
|
||
int main()
|
||
{
|
||
vector<string> msg {"Hello", "C++", "World", "from", "VS Code", "and the C++ extension!"};
|
||
|
||
for (const string& word : msg)
|
||
{
|
||
cout << word << " ";
|
||
}
|
||
cout << endl;
|
||
}
|
||
```
|
||
|
||
## 3 编译helloworld
|
||
> tasks.json
|
||
|
||
* tasks负责执行一些任务。主要由vscode的脚本提供支持。是vscode用来运行操作系统脚本的工具。
|
||
* tasks可以在`命令列表>tasks:`中找到， **其中C/C++插件提供了默认的内容** 。
|
||
```json
|
||
{
|
||
"version": "2.0.0",
|
||
"tasks": [
|
||
{
|
||
"type": "shell",
|
||
"label": "C/C++: g++.exe build active file",
|
||
"command": "C:\\Program Files\\mingw-w64\\x86_64-8.1.0-posix-seh-rt_v6-rev0\\mingw64\\bin\\g++.exe",
|
||
"args": ["-g", "${file}", "-o", "${fileDirname}\\${fileBasenameNoExtension}.exe"],
|
||
"options": {
|
||
"cwd": "${workspaceFolder}"
|
||
},
|
||
"problemMatcher": ["$gcc"],
|
||
"group": {
|
||
"kind": "build",
|
||
"isDefault": true
|
||
}
|
||
}
|
||
]
|
||
}
|
||
```
|
||
|
||
## 4 运行helloworld
|
||
> launch.json
|
||
|
||
* launch负责运行和调试任务。主要由vscode脚本提供支持。也是vscode用来兼容系统调试工具的。
|
||
* launch有可视化的界面，`运行`栏目和左侧的`Debug`栏目都能生成launch文件，配置运行和调试任务。其中 **c/c++插件提供了默认的运行和调试内容** 。
|
||
|
||
```json
|
||
{
|
||
"version": "0.2.0",
|
||
"configurations": [
|
||
{
|
||
"name": "g++.exe - Build and debug active file",
|
||
"type": "cppdbg",
|
||
"request": "launch",
|
||
"program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
|
||
"args": [],
|
||
"stopAtEntry": false,
|
||
"cwd": "${workspaceFolder}",
|
||
"environment": [],
|
||
"externalConsole": false,
|
||
"MIMode": "gdb",
|
||
"miDebuggerPath": "C:\\Program Files\\mingw-w64\\x86_64-8.1.0-posix-seh-rt_v6-rev0\\mingw64\\bin\\gdb.exe",
|
||
"setupCommands": [
|
||
{
|
||
"description": "Enable pretty-printing for gdb",
|
||
"text": "-enable-pretty-printing",
|
||
"ignoreFailures": true
|
||
}
|
||
],
|
||
"preLaunchTask": "C/C++: g++.exe build active file"
|
||
}
|
||
]
|
||
}
|
||
```
|
||
|
||
## 5 调试helloworld
|
||
|
||
1. 启用调试会话。启动调试会话的方式主要有三种：菜单栏-运行。侧边栏-调试。C/C++命令行：生成和调试任务。
|
||
2. 设置调试断点
|
||
3. 选择调试步骤：跳过过程、进入过程、跳出过程
|
||
4. 选择调试变量
|
||
|
||
## 6 环境配置
|
||
> c_cpp_properties.json
|
||
|
||
* c_cpp_properties.json提供了继承环境的配置功能。主要用来配置c/c++插件
|
||
* c_cpp_properties可以在 **C/C++插件的命令列表** 里选择配置。
|
||
* includePath 仅当程序包含工作空间或标准库路径中没有的头文件时，才需要添加到“包含路径数组”设置中。
|
||
* compilerPath设置来推断C ++标准库头文件的路径。当扩展知道在哪里可以找到那些文件时，它可以提供诸如智能补全和“转到定义”导航之类的功能。
|
||
|
||
```json
|
||
{
|
||
"configurations": [
|
||
{
|
||
"name": "GCC",
|
||
"includePath": ["${workspaceFolder}/**"],
|
||
"defines": ["_DEBUG", "UNICODE", "_UNICODE"],
|
||
"windowsSdkVersion": "10.0.18362.0",
|
||
"compilerPath": "C:/Program Files/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/bin/g++.exe",
|
||
"cStandard": "c11",
|
||
"intelliSenseMode": "gcc-x64"
|
||
}
|
||
],
|
||
"version": 4
|
||
}
