Sorry; much more information about the issue that you are hitting would be needed to triage the report.

With no other context than "redefine", the error like a standard C++ error regarding some incorrect usage where you have multiple definitions (eg, you have your headers without #ifndefs, or trying to #include multiple different versions of protobuf into the same project, etc).
