使用VSC调试开源项目 – iproute2

使用VSC阅读代码有非常舒服的感觉,如果能再加上调试,那就更爽了,而很多开源项目本身也比较大,直接阅读代码还是有点困难的,所以最好还是上调试,调试也很简单,无非是调用gdb,所以先新建一个简单的任务tasks.json,用来指代编译过程,具体根据项目而定.

{
    "tasks": [
        {
            "type": "shell",
            "label": "Makefile",
            "command": "make",
            "problemMatcher": [],
        }
    ],
    "version": "2.0.0"
}

接着创建launch.json,来指代要调试的内容,比如假设我这里要看的是iproute2中的ip -6 address命令,那么就写下来.

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/ip/ip",
            "args": ["-6","address"],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "Makefile"
        }
    ]
}

最后按F5,顺利进入调试.
