3 years ago Hey @zachary-koumi,
I'm pretty sure the problem is that you've set your compiler to C++98 as indicated by this line in your compiler output:
HowToUse.ino:42:36: error: in C++98 ‘B’ must be initialised by constructor, not by ‘{...}’This library relies on features from C++11 so you'll need to change that setting in your IDE. I've never had occasion to do that but by the looks of it you can find some information on how to do that here: https://forum.arduino.cc/t/changing-finding-out-the-c-compiler-version/604413

When i try to compile the example 'HowToUse.ino' using the arduino ide i get a whole bunch of errors.
