[开发工具]学习|在Ubuntu16.04下配置VScode的C/C++开发环境

1. 在主空间下新建文件夹，用vscode打开这个文件夹，写好一个cpp文件；
2. 更改配置文件（launch.json）：
   点击左侧的Debug按钮，选择C++（GDB/LLDB)，将自动生成launch.json文件；`

    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch", 
            "type": "cppdbg",
            "request": "launch",
            "program": "enter program name, for example ${workspaceFolder}/a.out",
            //将上面的代码改为将要进行调试的程序的路径
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

改后的launch.json文件如下：

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/${fileBasenameNoExtension}.out",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "preLaunchTask": "build", //为新的代码重新创建launch任务
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

3.添加构建（编译、链接等）任务（tasks.json）
利用快捷键ctrl+shift+p打开命令行，输入Tasks: Run task，生成默认的tasks.json文件如下：

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "echo",
            "type": "shell",
            "command": "echo Hello"
        }
    ]
}

这里的label为任务名，我们将”label"= “echo"改为”label”= “build”。
由于我们的指令是g++，这里将”command“=”echo Hello“改为”command“=”g++“。
然后添加g++的参数args。配置g++指令为：g++ -g main.cpp -std=c++11 -o main.out，则参数可设置为：

{
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "g++",
            "args": ["-g", "${file}", "-std=c++11", "-o", "${fileBasenameNoExtension}.out"]
        }
     ]
}

至此，完成了Ubuntu16.04 LTS下vscode的C/C++配置。
