1. MSYS2

国内使用中科大的源，详见：

pacman -S mingw-w64-x86_64-toolchain

1.1 踩过的坑

初始直接安装

pacman -S gcc

而gcc -version 后发现是 7.4 而非 8.2 的。

后使用指令后版本变成 8.2 了。

pacman -S mingw-w64-x86_64-gcc

但后来 gdb 时还需要手动安装一下。若空间足够，可以手动安装。

pacman -S mingw-w64-x86_64-gdb

2. 使用 make 跑一下

test.cpp

#include
    
     int main(void) {    long int tag = __cplusplus;    if(tag == 201703L) std::cout << "C++17\n";    else if(tag == 201402L) std::cout << "C++14\n";    else if(tag == 201103L) std::cout << "C++11\n";    else if(tag == 199711L) std::cout << "C++98\n";    else std::cout << "pre-standard C++\n";        return 0;}

makefile

CPPFLAGS=-Wall -std=c++17all:testclean:    rm test.exe

结果：

$ ./test.exeC++17

3. 使用 Visual Studio Code

3.1 安装扩展：C/C++

3.2 新建文件夹

File -> Open Folder， Create a new Folder 'test'

create a new file test.cpp， the same as 2.

3.3 配置文件

create a dir .vscode with 3 files.

c_cpp_properties.json

{    "configurations": [        {            "name": "Win32",            "includePath": [                "c:\\msys64\\mingw64\\include",                "c:\\msys64\\mingw64\\lib\\gcc\\x86_64-w64-mingw32\\8.2.1\\include",                "${workspaceFolder}/**"            ],            "defines": [                "_DEBUG",                "UNICODE",                "_UNICODE"            ],            "compilerPath": "C:\\msys64\\mingw64\\bin\\gcc.exe",            "cStandard": "c11",            "cppStandard": "c++17",            "intelliSenseMode": "clang-x64"        }    ],    "version": 4}

用于编译的 tasks

tasks.json

{    "version": "2.0.0",    "tasks": [        {            "label": "g++",            "type": "shell",            "command": "g++",            "args": [                "${file}", "-g", "-o", "${fileDirname}/${fileBasenameNoExtension}.exe", "-std=c++17"            ],            "group": {                "kind": "build",                "isDefault": true            }        }    ]}

用于运行加载的launch.json

{    "version": "0.2.0",    "configurations": [        {            "name": "(gdb) Launch",            "type": "cppdbg",            "request": "launch",            "program": "${fileDirname}/${fileBasenameNoExtension}.exe",            "args": [],            "stopAtEntry": false,            "cwd": "${workspaceFolder}",            "environment": [],            "externalConsole": false,            "MIMode": "gdb",            "miDebuggerPath": "c:\\msys64\\mingw64\\bin\\gdb.exe",            "setupCommands": [                {                    "description": "Enable pretty-printing for gdb",                    "text": "-enable-pretty-printing",                    "ignoreFailures": true                }            ],            "preLaunchTask": "g++"        }    ]}
