Building error on Kinetic: protoc version

[7675t]

I have followed this instruction (on the ROS Kinetic tabs): http://sdk.rethinkrobotics.com/wiki/Simulator_Installation

I got errors on protobuf version:

In file included from /usr/include/gazebo-7/gazebo/msgs/MessageTypes.hh:7:0,
                 from /usr/include/gazebo-7/gazebo/msgs/msgs.hh:32,

The environment is ROS Kinetic, Ubuntu16.04, all packages(including protobuf-compiler, version is 3.1.0) are upgraded. How can I build the baxter simulation? Thanks.

did you use https://github.com/RethinkRobotics/baxter_simulator/blob/kinetic-devel/baxter_simulator.rosinstall workspace?

Yes, I followed the official instruction and it is identical to you've shown.

[k-okada]

how did you install protobuf-compile 3 ?

https://packages.ubuntu.com/xenial/protobuf-compiler

k-okada@p51s:~$ apt show protobuf-compiler
Package: protobuf-compiler
Version: 2.6.1-1.3
Priority: extra

Uh, I see. I completely forget I had installed ppa version of protobuf for some other package (may be google cartographer). I did ppa-purge and now I can build all. Thanks, and sorry for bothering.
