VSCode远程Linux断点调试C++

由于手上有一台强大的Linux工作站，尽管在Windows下使用Visul Studio写C++十分舒服，但是考虑到以后很多工作都是在Linux下完成，所以需要配置C++的远程调试环境。
使用Remote SSH插件连接远程工作站，在项目目录下的.vscode里配置task.json和launch.json如下：

task.json

看起来很长，实际上在Linux下面只写label为g++ build active file的配置就可以，其他是为了方便兼容Windows的cl编译任务

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: cl.exe 生成活动文件",
            "command": "cl.exe",
            "args": [
                "/Zi",
                "/EHsc",
                "/nologo",
                "/Fe:",
                "${fileDirname}\Bin\${fileBasenameNoExtension}.exe",
                "${file}"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$msCompile"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "调试器生成的任务。"
        },
        //这个任务是为了在Windows下清除cl编译器生成的*.obj、*.ilk等文件
        //remove.bat可以参考：https://blog.csdn.net/qq_39091609/article/details/124253746
        {
            "label": "clean win32",
            "type": "shell",
            "command": "./.vscode/remove.bat",
            "options": {
                "cwd": "${fileDirname}"
            },
            "dependsOn": ["C/C++: cl.exe 生成活动文件"]
        },
        {
            "type": "shell",
            "label": "g++ build active file",
            "command": "g++",
            //亲测这几个参数很重要
            "args": [
                "-g", 
                "-O0",
                "${file}", 
                "-D_GLIBCXX_DEBUG",
                "-o", 
                "${fileDirname}/Bin/${fileBasenameNoExtension}"
            ],
            "options": {
              "cwd": "${fileDirname}"
            },
            "problemMatcher": ["$gcc"],
            "group": {
              "kind": "build",
              "isDefault": true
            }
        }

    ],
    "version": "2.0.0"
}

launch.json

同样的配置了两个调试启动器，可以在调试界面选择使用哪个启动器，Linux下用G++，Windows用cl.exe

            "miDebuggerArgs": "-q -ex quit; wait() { fg >/dev/null; }; /usr/bin/gdb -q --interpreter=mi"
          }
    ]
}

配置完成后按F5即可断点调试
