VSCode配置C/C++ GDB调试环境[Windows]

折腾了两个小时，终于把 VSCode 调试环境弄好了 （开心

VSCode

安装 C/C++ for Visual Studio Code 插件

  1. 按下 Ctrl+Shift+X
  2. 在搜索框中输入 C/C++
  3. 安装第一个插件

至此 VSCode 环境部分配置完毕

安装 MinGW

  1. 下载 MinGW
  2. 点击Continue开始安装，安装过程需联网，若安装时提示error则需使用梯子进行安装
  3. 当Continue按钮恢复为可用状态，点击完成安装

GCC 环境安装

  1. 打开 MinGW
  2. 选中左栏的Basic Setup,然后选中mingw32-gcc-g++-bin,右键选择Mark for installation
  3. 选中All packages,找到mingw32-gdb-bin,mingw32-gdb-doc,mingw32-gdb-info,mingw32-gdb-lang,mingw32-gdb-lic,mingw32-gdb-man,右键选择Mark for installation
  4. 点击左上角的installation,然后点击Apply Changes
  5. 点击Apply,等待安装完成,点击 close

至此 GDB 环境部分配置完成

MinGW 配置较为繁琐，可以考虑使用MinGW64，MinGW64 安装后就不需上方的配置，一路点击下一步即可。（但是还是要配置环境变量

添加环境变量

  1. 进入设置,点击系统,然后选择关于,然后点击右侧系统信息
  2. 在弹出的系统信息中,选中左栏高级系统设置,然后选中环境变量
  3. 在系统变量一栏中找到Path,双击,然后新建一个C:\MinGW\bin 的变量
  4. 一路确定,直到关闭所有选卡

配置 VSCode

新建一个cpp文件,写上以下测试代码

1#include <iostream>
2int main()
3{
4    using namespace std;
5    cout << "Test 1";
6    cin.get ();
7    return 0;
8}

Ctrl+S 保存,然后按 F5,VSCode 会在上方弹出选择环境,选择C++(GDB/LLDB),然后将以下代码覆盖至launch.json,注意miDebuggerPath路径要对应

1{
2  // Use IntelliSense to learn about possible attributes.
3  // Hover to view descriptions of existing attributes.
4  // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
5  "version": "0.2.0",
6  "configurations": [
7    {
8      "name": "(gdb) Launch",
9      "type": "cppdbg",
10      "request": "launch",
11      "program": "${fileDirname}/${fileBasenameNoExtension}.exe",
12      "args": [],
13      "stopAtEntry": false,
14      "cwd": "${workspaceFolder}",
15      "externalConsole": true,
16      "MIMode": "gdb",
17      "miDebuggerPath": "C:/MinGW/bin/gdb.exe",
18      "setupCommands": [
19        {
20          "description": "Enable pretty-printing for gdb",
21          "text": "-enable-pretty-printing",
22          "ignoreFailures": true
23        }
24      ],
25      "preLaunchTask": "Build"
26    }
27  ]
28}

回到新建的cpp中,按下 F5,会显示找不到任务,点击配置任务,点击使用模板创建,然后点击带有Other的选项,用以下代码覆盖tasks.json

1{
2  "version": "2.0.0",
3  "tasks": [
4    {
5      "label": "Build",
6      "command": "g++",
7      "args": [
8        "-g",
9        "-Wall",
10        "-std=c++11",
11        "-lm",
12        "${file}",
13        "-o",
14        "${fileDirname}/${fileBasenameNoExtension}.exe"
15      ],
16      "presentation": {
17        "reveal": "always",
18        "echo": false,
19        "focus": true
20      },
21      "problemMatcher": {
22        "owner": "cpp",
23        "fileLocation": "absolute",
24        "pattern": {
25          "regexp": "^(.*):(\\d+):(\\d+):\\s+(error):\\s+(.*)$",
26          "file": 1,
27          "line": 2,
28          "column": 3,
29          "severity": 4,
30          "message": 5
31        }
32      }
33    },
34
35    {
36      "label": "Run",
37      "type": "shell",
38      "dependsOn": "Build",
39      "command": "${fileDirname}/${fileBasenameNoExtension}.exe",
40      "args": [],
41      "presentation": {
42        "reveal": "always",
43        "focus": true
44      },
45      "problemMatcher": [],
46      "group": {
47        "kind": "test",
48        "isDefault": true
49      }
50    }
51  ]
52}

Ctrl+S 保存,然后回到新建的cpp,按下 F5,程序就会被编译运行,至此 GDB 调试环境便配置完成.

对了,C/C++也是可以进行断点调试的,具体方法可以参考 VSCode 配置 PHP 调试环境[Windows]

在使用过程中你可能会遇到输入或输出中文乱码的问题，此时只需要将文件改成 GB2312 编码即可
