部分配置参数

${workspaceFolder} - 当前工作目录(根目录)
${workspaceFolderBasename} - 当前文件的父目录
${file} - 当前打开的文件名(完整路径)
${relativeFile} - 当前根目录到当前打开文件的相对路径(包括文件名)
${relativeFileDirname} - 当前根目录到当前打开文件的相对路径(不包括文件名)
${fileBasename} - 当前打开的文件名(包括扩展名)
${fileBasenameNoExtension} - 当前打开的文件名(不包括扩展名)
${fileDirname} - 当前打开文件的目录
${fileExtname} - 当前打开文件的扩展名
${cwd} - 启动时task工作的目录 Current Working Directory
${lineNumber} - 当前激活文件所选行
${selectedText} - 当前激活文件中所选择的文本
${execPath} - vscode执行文件所在的目录
${defaultBuildTask} - 默认编译任务(build task)的名字

首先在Debug/Run中创建一个.vscode文件.

Ubuntu VsCode 多文件编译运行

我是做一个TCP Server和Client的通信,下面是我的文件树

        }
     ]
}

    ],
    "compounds": [
        {
          "name": "Server/Client",
          "configurations": ["Server", "Client"],//运行这两个config
        }
      ]
}

还有一种是makefile运行
因为我不会makefile,所以就把makefile都放在src下了,本来需要分成release/build什么的,有空研究一下makefile怎么写.文件树中的c_cpp_properties.json不需要.

文件树

makefile

all:server client
server:server.o
    g++ -g -o server server.o
client:client.o
    g++ -g -o client client.o
server.o:server.cpp
    g++ -g -c server.cpp
client.o:client.cpp
    g++ -g -c client.cpp
clean:all
    rm all

tasks.json

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

launch.json

{
    // 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": "Server",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/src/server",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        },
        {
            "name": "Client",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/src/client",
            "args": ["127.0.0.1"],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ],
    "compounds": [
        {
          "name": "Server/Client",
          "configurations": ["Server", "Client"],
          "preLaunchTask": "make",
        }
      ]
}

主要是理解compunds的使用

可以一起run也可以分开run
