Using C++11 with VSCode

I created a new project with the platformio extension for vscode, but in the .vscode\c_cpp_properties.json file generated by platformio, i read “cppStandard”: “c++98”. In fact the error squiggles underline some errors due to c++11 specific features, but the code compiles just fine. How can i change it?

I tried setting

build_flags = -std=c++11

the code compiles just fine like it did before, but the squiggle still appear even if i restart vscode, from what i can see the file c_cpp_properties.json is regenerated at startup, still with the wrong flag

“cppStandard”: “c++98”,

If i change the flag manually, the squiggles go away, but i lose it when vscode is restarted.
If i try setting the unflag for c++11:

build_unflags = -std=c++11

platformio compiles with the warning for c++11 features, as a proof that it’s reading that flag

warning: extended initializer lists only available with -std=c++11 or -std=gnu++11

Did you re-initialize the project files after setting build_flags = -std=c++11 and maybe build_unflags = -std=c++98 (or maybe gnu++98) by using pio init --ide=vscode?

I did now, the result is the same. I think vscode does that by itself since the file is regenerated upon startup

Could you provide platformio.ini? What is your dev/platform//board?

You can see the repository of the project here:

Please open PlatformIO IDE Terminal and type pio upgrade --dev. Fixed in
