在mingw14.2版本中, print库的功能默认没有开启, 生成可执行文件的tasks.json里要显式加-lstdc++exp, 注意放置顺序. 

tasks.json (支持mingw g++14.2 c++23的print )

{"version": "2.0.0","tasks": [{"type": "cppbuild","label": "C/C++: g++.exe build","command": "D:\\code\\sfml3_0\\mingw64_1420\\bin\\g++.exe","args": ["-std=c++23","-fdiagnostics-color=always","-g","*.cpp","-lstdc++exp" //注意放置顺序一定要放到最下面,系统Path也要配置.],"options": {"cwd": "${fileDirname}"},"problemMatcher": ["$gcc"],"group": {"kind": "build","isDefault": true},"detail": "编译器: D:\\code\\sfml3_0\\mingw64_1420\\bin\\g++.exe","presentation": {"reveal": "silent","revealProblems": "onProblem","close": true}}]
