Question

When using an enum in C++, I like to use EnumName::Value (as opposed to just Value). In C++ this is either a warning or an error, depending on compiler settings.

In XCode, what’s the name of the setting that will allow me to not have this come up as a compiler error?

(Taking the ErrorLevel:: away resolves the error)

• if you use c++11, your syntax is correct:

  enum EnumName
  {
  Value 
  }
  ...
  EnumName n = EnumName::Value;
  

  Also note, that if you use c++11, you can require usage of EnumName::Value instead of just Value by using enum class instead of enum:

  enum class EnumName
  {
  Value 
  }
  ...
  EnumName n = EnumName::Value; //ok
  EnumName fuuu = Value; // compilation error
  

• otherwise, you can wrap your enum declaration with namespace

  namespace EnumName {
  enum EnumName
  {
  Value 
  }
  }
  ...
  EnumName::EnumName n = EnumName::Value;
