Support for GCC 5.4? #45

Closed manhnt9 closed 5 years ago

manhnt9 commented 7 years ago

I know 5.4 is not officially supported but I still report for further development. Please support it if possible. Compile errors on Linux 64-bit gcc 5.4.0

manhnt9 commented 7 years ago

strange, I installed clang 3.9 and get the same errors. My code is just: BETTER_ENUM(Word, int, Hello, World)

aantron commented 7 years ago

Can you show a complete (perhaps minimal) example that causes this?

manhnt9 commented 7 years ago

I tested on a independent source file, there was no error, but I couldn't integrate it to my current project. Do you have any ideas about what may cause the the errors?

aantron commented 7 years ago

Is the enum declared inside class, or is the file that declares it included inside a class (doesn't look so from the error trace, but just in case)?

It's been a while, so I'm not super familiar with GCC error messages anymore, but IIRC this is the main limitation of Better Enums. See https://github.com/aantron/better-enums#limitations.

Closing. Please reopen if this was not solved and you would like to look into it again.
