Windows中VS code debug时无法查看C++ STL容器内容

首先,你很可能用的是x64版本的Windows。

我发现一个有效的解决方法,但在x64版本的Windows上安装MinGW时,虽然官方推荐MinGW版本的是x86_64的,但实践后发现如果选择安装 x86_64的, 很可能Debug时会无法看到STL容器(vecotr、map等)的具体信息,看到的是相应的内存地址~

故建议选 i686 (win32)的,然后安装步骤的下一步及后面的操作都按默认的来就好。

最后的效果:
pretty-printing-not-work-with-MinGW GDB-solution

win32 版本的 MinGW官方下载地址:

i686-posix-dwarf

我从这里下载到 MinGW 压缩包,然后解压到文件夹 D:\MinGW 中,接下来把MinGW的bin目录,即 D:\MinGW\i686-8.1.0-release-posix-dwarf-rt_v6-rev0\mingw32\bin 加到了系统变量的 PATH 中。

将MinGW添加到系统变量

而我相应的配置文件如下:

1、.vscode\tasks.json

{
    "tasks": [
        {
            // "type": "shell",
            "label": "C/C++: g++.exe build active file",
            "command": "g++",
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe"
            ],
            "options": {
                "cwd": "${workspaceFolder}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ],
    "version": "2.0.0"
}

2、.vscode\launch.json

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.    
    "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": "gdb",
            "setupCommands": [
                {   // Display content in STL containers pretty
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "C/C++: g++.exe build active file"
        }
    ]
}

3、 .vscode\c_cpp_properties.json

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "windowsSdkVersion": "10.0.19041.0",
            "compilerPath": "g++", // Or complete absolute path "D:/MinGW/i686-8.1.0-release-posix-dwarf-rt_v6-rev0/mingw32/bin/g++.exe"
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "clang-x86"
        }
    ],
    "version": 4
}

附上我的电脑的环境配置

VSCode Version: 1.53.2 (system setup)
OS Version: Windows 10 x64 (Windows_NT x64 10.0.19041)
MinGW version: i686-8.1.0-release-posix-dwarf-rt_v6-rev0
GDB version: 8.1.0 (Target: i686-w64-mingw32)
