I am new to the gazebo software and was working through the transport/custom messages tutorial. I have been able to get the main section of the code working si uit displays the world map. However, when I try to execute the request_publisher code it gives me this error:

[libprotobuf ERROR google/protobuf/descriptor_database.cc:57] File already exists in database: vector2d.proto [libprotobuf FATAL google/protobuf/descriptor.cc:1018] CHECK failed: generated_database_->Add(encoded_file_descriptor, size): terminate called after throwing an instance of 'google::protobuf::FatalException' what(): CHECK failed: generated_database_->Add(encoded_file_descriptor, size): Aborted (core dumped)

How can I resolve this?

thanks
