Error compiling for board RaspberryPI B+/2.

[ethr0]

I attempting to compile the radiolib/si443x/Si443x_Receive_Interrupt example for raspberry pi but it does not succeed,

it compiled successfully for Arduino Uno and ESP32.

for Raspberry Pi it gives to me a long error, every thing like that:

I had the same issue, solved it by adding -std=gnu++11 to platforms.txt'scompiler.cpp.flags:

compiler.cpp.flags=-c -pipe -std=gnu++11

The issue is that RasPiArduino's c++ compiler defaults to some ancient version of C++.
