Using C++20 with ESP32S3

[avsteele]

How can I enable cpp20 usage for Arduino framework code which uses the c++20 standard? Right now the latest I can get it to do is 2017 (what the __cplusplus macro reports). See attached image showing a c++20 feature which make it unable to compile.

I typically use PlatformIO in VSCode but am open to other solutions as well.

Code: Select all

build_unflags = -std=gnu++11
build_flags =
    -std=gnu++20

Im not sure if its working for C++20 but worked for C++17 for sure.

Hello,

As you’ve asked for other solutions, you can also think about ESP-IDF for your development, and we have VSCode extension for it and it supports latest C++ version as well.

By default, ESP-IDF compiles C++ code with C++23 language standard with GNU extensions (-std=gnu++23).
