this is my
[env:adafruit_itsybitsy_m4] platform = atmelsam board = adafruit_itsybitsy_m4 framework = arduino lib_deps = https://github.com/davidbitton/legilimens.git https://github.com/davidbitton/senoval.git build_flags = -Wall -std=c++17
which results in
arm-none-eabi-g++: error: unrecognized command line option '-std=c++17'
I ran this from the command line:
$ arm-none-eabi-g++ -std=c++17 arm-none-eabi-g++: fatal error: no input files compilation terminated.
and while I had nothing to compile, I had no unknown command error. Is PlatformIO using it’s own version of the compiler? What do I need to do to compile with c++17? Thanks!
