[env:nodemcuv2] platform = espressif8266 board = nodemcuv2 framework = arduino ;build_unflags = -Os -std=gnu++11 build_flags = -std=c++14 -O3
this is my platformio.ini. It does not recognize the c++14 flag.
xtensa-lx106-elf-g++: error: unrecognized command line option ‘-std=c++14’
What version of gcc is exactly used here by PlatformIO? Is C++14 even supported?
GitHub - jcmvbkbc/gcc-xtensa: gcc for xtensa anyone knows what standard is supported?
