Visual Studio Code c++11 extension warning

Question

I am in the process of learning c++ and I\'m using visual studio code for Mac. I use Code Runner to run my program. My problem is that when I use something from c++11 like \

Answer 1

In VS Code:

File>>Preference>>Settings>>Extensions

find C_Cpp>Default:Cpp Standard drop down menu

set that to c++11

Answer 2

I had the same problem, but solved it using set vscode-user-settings <>

"clang.cxxflags": ["-std=c++14"]

Answer 3

I spent so long today trying to figure out why I was getting this error and no where had the exact answer I required so I thought I'd post it here just in case I can save anyone the hassle.

If you're using code runner, look in user settings and set:

 "code-runner.executorMap" : { "cpp" : "cd $dir && g++ -std=c++17 $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt" }

The pertinent bit being "g++ -std=c++17".

This is providing of course you can compile your programme in shell using Daniel's solution above but not in VScode + and using code runner.

Answer 4

For everyone who comes to this question to find a quick answer (like I did):

The following compiler command should compile your program main.cpp with the latest C++ standard (c++17) and should get rid of warning messages like the one described above:

g++ -std=c++17 -g main.cpp -o main

It is mentioned multiple times in the comments, but I think this question should have a regular answer.

Answer 5

I used this to solve my problem. Open your terminal

bash

echo "alias g++='g++ -std=c++17'" >> ~/.bashrc
source ~/.bashrc

zsh

echo "alias g++='g++ -std=c++17'" >> ~/.zshrc
source ~/.zshrc
