Microsoft Visual C++ Compiler error C2248 if using a Better Enum as a member in a class with a user-defined constructor about better-enums HOT 4 CLOSED

This issue is a duplicate of #33. Sorry, but maybe the information provided here helps too.

This is also a problem if using Better Enums in a container, e.g. std::array<Boolean, 8>. Another example is this usage of boost::program_options:

boost::program_options::value<Boolean>(&boolean_)
      ->required()

What do I have to change to get rid of this bug? I think a workaround would be to initialize a Better Enum to the value of the first enumerator by default (or better: to no value, UB - same as with enum class), but I cannot find the construction code (too much macros and templates). 😢

I think I got it. I modified https://github.com/aantron/better-enums/blob/master/enum.h#L1041 and changed private to public. Now I still have a problem with the boost::program_options::value<Boolean>(&boolean_) call:

D:\win-dev-env\native\boost\boost-1.63.0-x86\include\boost-1_63\boost\lexical_cast\detail\converter_lexical.hpp:243: Fehler: C2338: Target type is neither std::istream`able nor std::wistream`able

Why doesn't boost pick up the operator >> in enum.h?

Edit: I've used the latest release version and updated to HEAD now. Still the constructor visibility is bugged. But despite that it seems to work now.

Doh, I did not see http://aantron.github.io/better-enums/DesignDecisionsFAQ.html, so nevermind. Your library is awesome. For others: This link describes how-to change default behavior.
