vscode+CMake+Debug实现 及权限不足等诸多问题汇总

环境说明

有空再补充

直接贴两个json

tasks.json

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "cmake",
            "type": "shell",
            "command": "cmake",
            "args": [
                "../"
            ],
            "options": {
                "cwd": "${fileDirname}/../build"
            },            
        },
        {
            "label": "make",
            "type": "shell",
            "command": "make",
            "args": [],
            "options": {
                "cwd": "${fileDirname}/../build"
            }, 
        },
        {
            "label": "build",
            "dependsOn":["cmake", "make"]
        },
    ],
}

为了防止出错，“cwd”: "${fileDirname}/…/build"建议写绝对地址，我的src和build是分开的，大家的不一定和我一样

launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "g++ - Build and debug active file",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/../lib/${fileBasenameNoExtension}",
            "args": ["para1", "para2"],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
            "environment": [
                {
                    "name": "LD_LIBRARY_PATH",
                    "value": "${workspaceFolder}/lib:$LD_LIBRARY_PATH"
                }
            ],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "build",
            // "miDebuggerPath": "/usr/bin/gdb"
            "miDebuggerPath": "/home/USERID/Desktop/aheadform/wukong_large/Proj_01/run.sh"
        }
    ]
}

• 注意事项

1. 使用"miDebuggerPath": "/usr/bin/gdb"可能会导致某些接口没有足够权限调用，或者每次需要输入密码的情况发生，故这里改成了 “miDebuggerPath”: “/home/USERID/Desktop/aheadform/xxxx/Proj_01/run.sh”，用一个脚本间接启动gdb，注意这里填脚本的地址，脚本放哪里都行

   #!/bin/bash
   
   exec sudo /usr/bin/gdb "$@"
   

   在创建完脚本后，要用

   sudo chmod + x 脚本.sh
   //或者
   sudo chmod 777 脚本.sh
   

   为脚本赋予执行权限
2. 编译时，可能会出现某某环境变量找不到的现象，"environment"就是用来解决这个的，哪个环境变量找不到，就把它塞进"environment"里，按照

   		{
                "name": "LD_LIBRARY_PATH",
                "value": "${workspaceFolder}/lib:$LD_LIBRARY_PATH"
           }
   

   的格式添加需要的环境变量，比如我这里就是LD_LIBRARY_PATH找不到（编译时报错提示电脑不认识.so库的路径）
3. "program"的值是make生成的可执行文件的路径，不要被我这里误导了，我只是这个工程的环境依赖有点问题，所以生成到lib下面了，如果有同学和我这个奇葩工程一样的，记得修改这一项
