I am trying to compile on ubuntu 18.04 and receive the following error - file.pb.h:17:2: error: #error This file was generated by an older version of protoc which is #error This file was generated by an older version of protoc which is

protoc --version libprotoc 3.6.1

from google/protobuf/stubs/common.h

#define GOOGLE_PROTOBUF_VERSION 3006001

So looks like the versions match. I did do a remove of any older versions just in case using the following link https://www.howtoinstall.co/en/ubuntu/trusty/protobuf-compiler?action=remove

What am I missing here ?

You need to recompile `file.proto`, which will produce fresh copies of `file.pb.h` and `file.pb.cc` – Igor Tandetnik Dec 17 '18 at 03:36
@IgorTandetnik Got it to compile. Thanks – ksoop Dec 17 '18 at 10:07
