If you are just trying to run the examples you shouldn't use the g++ command. Instead, follow the steps in the README <https://github.com/protocolbuffers/protobuf/tree/master/examples#readme>, specifically under "Build the example using make".'
The g++ command you are trying to run is only to compile dependent packages (which isn't needed to run the examples).
