Hello,

Hello,

I am experiencing the same issue, but with a different system configuration. I will leave my notes on the issue here and if this is not a proper place, I will open new issue for it later.

lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 16.04.5 LTS
Release:	16.04
Codename:	xenial

Today I upgraded Gazebo to version

gazebo9/unknown,unknown,now 9.3.0-1~xenial amd64 [installed]

After that in order to be able to compile Gazebo plugins, u installed libgazebo9-dev, that forced me to update libprotobuf-dev and protobuf-compiler from 2.6.1-1.3 to 3.1.0
I dont have a trace of the installation, but if I force downgrade of libprotobuf-dev, I get

sudo apt install libprotobuf-dev=2.6.1-1.3
The following packages will be REMOVED:
  libgazebo9-dev libignition-msgs-dev libignition-transport4-dev libprotoc-dev
The following packages will be DOWNGRADED:
  libprotobuf-dev

I think that while Gazebo 9.3.0 ( at least development package ) is configured to use Protobuf 3.1.0, package

libignition-msgs/unknown,unknown,now 1.0.0-2~xenial amd64 [installed,automatic]

was not updated for release of Gazebo 9.3.0 and that is what is causing these problems. Unfortunately I cannot tell if the case is that Gazebo 9.3.0 updated protobuf and ign-msgs are left behind, or the other way around.

Hello:

Opening the /usr/include/ignition/msgs1/ignition/msgs/color.pb.h file from package version 1.0.0+dfsg1-5 in my Bionic system it shows:

// Generated by the protocol buffer compiler.  DO NOT EDIT!
// source: ignition/msgs/color.proto

#ifndef PROTOBUF_ignition_2fmsgs_2fcolor_2eproto__INCLUDED
#define PROTOBUF_ignition_2fmsgs_2fcolor_2eproto__INCLUDED

#include <string>

#include <google/protobuf/stubs/common.h>

#if GOOGLE_PROTOBUF_VERSION < 3000000
#error This file was generated by a newer version of protoc which is
#error incompatible with your Protocol Buffer headers.  Please update
#error your headers.
#endif
#if 3000000 < GOOGLE_PROTOBUF_MIN_PROTOC_VERSION
#error This file was generated by an older version of protoc which is
#error incompatible with your Protocol Buffer headers.  Please
#error regenerate this file with a newer version of protoc.
#endif

It seems to be generated by protobuf3. Could you please post instructions about how could I reproduce your problems?
Thanks.

Hello,

I have double check and I get the same header than you. I revert back from ubuntu-proposed package, but I still get the error.
I get the problem with those simple instructions :

#!bash

git clone https://github.com/khancyr/ardupilot_gazebo
cd ardupilot_gazebo
mkdir build
cd build
cmake ..
make -j4

Thanks

I found the issue.
Because of the manual install of google-cartographer, protobuf3 was manually installed on my system. It overwrite system protobuf install and cannot be uninstall other than with make uninstall... Therefore I get the wrong protobuf compiler installed without knowing it...

Sorry for the noise ... Gazebo is the only projet where I need protobuf, so I didn't notice that before.
I release the error when the file got the right header and GOOGLE_PROTOBUF_VERSION was good in /usr/include/google/protobuf/stubs but the protoc --version return 3.4.0. And ubuntu 18.04 only install protoc 3.0.0 with apt install protobuf-complier.

I am closing this.

Hi pierre kancir (pkancir) , sorry for the interference. I’m now having problem with Google protobuf. Could you please give me some solution for following problems?

1. How can I uninstall google protobuf. I don’t know where to use the command make uninstall.
2. How can I install the proper google protobuf version?

Thanks in advance.

pierre kancir (pkancir) Can u please describe the steps you took to resolve this issue?
In my case protobuf-compiler is installed via rosdep install --from-paths src --ignore-src -r -y, so there is no make uninstall option that I’m aware of.

Here is a script to remove the invasive protobuf installation. You have to run it as sudo/root, please read what it deletes to make sure it will behave properly on your system but it fixed the issue for me and my team.
