ststm32 doesnt work with -std=gnu++17 and up

[DominikRzecki]

Hello there,

recently I tried to create an project based on the mbed framework for my nucleo_f446re. When I try to unflag -std=gnu++14 and flag -std=gnu++17 and up I get multiple errors. It seems that gccarmnoneeabi only works with c++14.

Is there any way to fix that?

edit: I also tried it with stm32cube and zephyr. Still nothing.
