怎么用vscode进行单步调试

1.修改launch文件

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/build/my_cmake_exe", //此路径更改为最终生成的可执行文件路径以及可执行文件名称
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole":false,//将此处的true改为false,不然他会调用系统的终端进行现实
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask":"Build",//在执行launch文件前执行cmake的编译
            "miDebuggerPath":"/usr/bin/gdb" 
        }
    ]
}

2、修改text文件

{
    "version": "2.0.0",
    "options":{
        "cwd": "${workspaceFolder}/build"
    },
    "tasks": [
        {
            "type": "shell",
            "label": "cmake",
            "command": "cmake",
            "args": [
                ".."
            ]
        },
        {
            "label":"make",
            "group":{
                "kind": "build",
                "isDefault": true
            },
            "command":"make",
            "args":[

            ]
        },    
        {
            "label":"Build",
                 "dependsOrder": "sequence",
                 "dependsOn":[
                    "cmake",
                    "make"
                 ]
        },      
              
    ],

}

launch里面"preLaunchTask":"Build"的Build和task里面的 “label”:"Build"保持一致。

“label”:“Build”,

Build
