What is the gcc version in my IDF (V4.3 beta1)

There should be an easy way to find out, right? I'm trying to determine what C++ standard the compiler conforms to so I know what language features are included. Thanks.

I wonder how quickly you gave up on looking for that, if at all.
There are at least 3 ways I can think of:

• $ xtensa-esp32-elf-g++ --version
• $ idf_tools.py list
• Check the folder name under <folder where idf tools are installed; defaults to ~/.espressif on Linux>/tools/xtensa-esp32{your ESP32 flavor here}-elf/

I apologize for not knowing how to use these tools that I didn't make. Both 1 and 2 produced 8.4.0 and 3 was simply not in my IDF (maybe you overgeneralized based on what you have?). Problem solved.
