How to enable C++17 support in VSCode C++ Extension
This has become much easier now. Search for cppstandard
in your vs code extension settings and choose the version of C++ you want the extension to use from the drop down.
In order to make sure your debugger is using the same version, make sure you have something like this for your tasks.json
, where the important lines are the --std
and the line after that defines the version.
{
"tasks": [
{
"type": "cppbuild",
"label": "C/C++: g++ build active file",
"command": "/usr/bin/g++",
"args": [
"-std=c++17",
"-I",
"${fileDirname}",
"-g",
"${fileDirname}/*.cpp",
"-o",
"${workspaceFolder}/out/${fileBasenameNoExtension}.o"
],
"options": {
"cwd": "${workspaceFolder}"
},
"problemMatcher": ["$gcc"],
"group": {
"kind": "build",
"isDefault": true
}
}
],
"version": "2.0.0"
}
Note that if you're copying the above tasks.json
directly, you'll need to have a folder named out
in your workspace root.

Using two consecutive >
to close out nested template declarations is not legal in C++98/03, but is legal in C++11 (and later).
Your command g++ filename.cpp
is (presumably) defaulting to C++98, while when you try g++ -std=c++17 -g filename.cpp
you are expressly indicating that you want to compile for C++17.

Any Visual Studio:

Thanks for the comments. I didn't know that i had to set the cppstandard in vs code to c++17 manually.
Simply go to: File -> Preferences -> Settings,
