Linux下的VSCode進行C++編譯及調試開發的配置

我這裏配置的是Linux下的VSCode，使用的編譯器是GCC，調試器是GDB
配置前先在終端中輸入gcc，gdb(按q退出)看一下是否安裝了g++和gdb
如果沒有安裝，deepin下直接輸入
sudo apt-get install g++
sudo apt-get install gdb
sudo apt-get install gcc

先配置launch.json，這裏面是關於C++或者C語言調試的配置
launch.json
這裏有幾個地方要注意，

1. “preLaunchTask”: “gcc”，這句話表示在啓動調試之前需要進行的任務，調試之前肯定是要編譯撒，gcc這個值是後面task.json中label標籤的值，你也可以取其他的。
2. program這個標籤中的值，注意要和後面的task.json中的cwd以及args標籤中-o參數的值要對應。task.json中的cwd和"-o","${fileBasenameNoExtension}"決定了編譯輸出的文件名以及位置。program的值需要和這個位置一樣，調試器才能找到該位置。

    "version": "0.2.0",
    "configurations": [
        {
            "name": "C++ (gdb)",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/build/${fileBasenameNoExtension}",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}/build",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "miDebuggerPath": "/usr/bin/gdb",
            "preLaunchTask": "gcc",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": false
                }
            ]
        }
    ]
}

然後是關於C++編譯的配置
task.json

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558 
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "type": "shell",
            "label": "gcc",
            "command": "/usr/bin/gcc",
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileBasenameNoExtension}"
            ],
            "options": {
                // "cwd": "/usr/bin"
                "cwd": "${workspaceFolder}/build"
            },
            "problemMatcher": [
                "$gcc"
            ]
        }
    ]
}
