protobuf version conflict #8

Closed Nianan0505 closed 4 years ago

Nianan0505 commented 4 years ago

My system is ubuntu16.04 gazebo8 and protobuf version is 3.6 When using FASTER with an aerial robot the step catkin build runs, and the errors occur as follows:

 #error regenerate this file with a newer version of protoc.
 #error regenerate this file with a newer version of protoc.

Which version should the protobuf is? Thank you sooo much for your reply.

Hi @Nianan0505!

So running protoc --version on my Ubuntu 16.04 machine says the protoc version installed is 2.6.1.

I think (and reading this) Gazebo is built againt the protoc version released to the ubuntu repos (which is 2.6.1 for Ubuntu 16.04).

Could you try to install Gazebo 7.0.0 (the one recommended for ROS Kinetic) and protoc version 2.6.1 instead? In the second answer of this question there are some steps that may be helpful to do this.

Thanks

Hi， @jtorde @Nianan0505 I have the same problem, and I use the husky A200 mobile platform. The protoc version drop to 2.6.1 will result in many other software configuration errors and failures, so the best way is not to install gazebo simulation modules. I met this problem and did this on the robot's computer, compiled correctly and passed......

Thank you so much for your help. I installed Gazebo 7, and did not meet this problem.
