How to configure c/c++ environment in vscode

一、安装cpptools工具

打开vscode,按照以下步骤安装

二、下载MinGW

下载地址:https://sourceforge.net/projects/mingw-w64/files/

下载的文件:进入网站后不要点击 "Download Lasted Version",往下滑,找到最新版的 "x86_64-posix-seh"。

安装MinGW:下载后是一个7z的压缩包,解压后移动到你想安装的位置即可。我的安装位置是:D:\2Software\mingw64

三、配置环境变量

配置对象:WinGW,所以把你刚刚安装WinGW的路径拷贝一下。

配置环境变量:在此以win10为例,到达第6步之后,前面打开的窗口都要按下确定,否则会失败。

【注】:win7需要添加路径,不要覆盖了。

配置好环境变量后最好重启一下 VScode 。

验证一下环境变量是否配置成功

按下 win + R,输入cmd,回车键之后输入g++,再回车,如果提示以下信息[1],则环境变量配置成功。如果提示以下信息[2],则环境变量配置失败。

四、使用简单的.cpp文件配置C++环境

新建空文件夹Code打开VScode --> 打开文件夹 --> 选择刚刚创建的文件夹Code

新建test.cpp文件(以最简单的 HelloWorld.cpp 为例)

#include <stdio.h>
#include <windows.h>
int main()
{
    printf("Hello World\n");
    system("pause");
    return 0;
}
Copy after login

进入调试界面添加配置环境,选择 C++(GDB/LLDB),再选择 g++.exe,之后会自动生成 launch.json 配置文件。

编辑 launch.json 配置文件

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "g++.exe build and debug active file",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,      //修改此项,让其弹出终端
            "MIMode": "gdb",
            "miDebuggerPath": "D:\\2Software\\mingw64\\bin\\gdb.exe",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "task g++" //修改此项
        }
    ]
}
Copy after login

返回.cpp文件,按F5进行调试,会弹出找不到任务"task g++",选择 "配置任务",会自动生成 tasks.json 文件。

编辑 tasks.json 文件

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "shell",
            "label": "task g++",    //修改此项
            "command": "D:\\2Software\\mingw64\\bin\\g++.exe",
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe"
            ],
            "options": {
                "cwd": "D:\\2Software\\mingw64\\bin"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": "build"
        }
    ]
}
Copy after login

【注】: launch.json 文件中 "preLaunchTask" 的值 必须与 tasks.json 文件中 "label"的值一致。值的设置看个人喜好,保持默认也是OK的。

五、运行

返回 HelloWorld.cpp 文件,按F5调试,发现完全OK了!
