Using this answer from Stack Overflow: https://stackoverflow.com/questions/46980383/how-to-determine-what-c-standard-is-the-default-for-a-c-compiler
I was able to determine the default std the arm-rtems5-g++ cross compiler (based off of GCC 7.3) is using GNU++14 (C++14) by printing out the __cplusplus macro to the console. This matches what the GCC website says the cross compiler should be using.

You can try to compile a simple application with c++11 features. For example just add #include <thread>.

Do you know what it uses by default if –std isn’t specified?

I’ve tried using –std=c++0x and –std=c++11 and both times I have gotten errors with type definitions in the standard includes. If the arm-rtems5-g++ cross compiler doesn’t support specifying which c++ standard to use then which standard is it using?
