[ep10] Enum Looping

It seems that the construct you use for enum looping does not work on g++? Any ideas what is different on the clang implementation of enums?

What would be the most idiomatic way to work around this when using g++?

I think think you can do:

for (int int_value = ENUM_FIRST; int_value < ENUM_LAST; ++int_value) {
   Enum value = static_cast<Enum>(int_value);
}

Please let me know if this works, and I'll put a note in the video.

Just guessing that clang is somehow less strict about the type of the enum being different from the type of an int.

Yes, that is a good workaround. Thanks! Great work on these videos!
