#gRPC in 3 minutes (C++)

Installation

To install gRPC on your system, follow the instructions to build from source here. This also installs the protocol buffer compiler protoc (if you don't have it already), and the C++ gRPC plugin for protoc.

Hello C++ gRPC!

Here's how to build and run the C++ implementation of the Hello World example used in Getting started.

The example code for this and our other examples lives in the examples directory. Clone this repository to your local machine by running the following command:

$ git clone https://github.com/grpc/grpc.git

Change your current directory to examples/cpp/helloworld

$ cd examples/cpp/helloworld/

Client and server implementations

The client implementation is at greeter_client.cc.

The server implementation is at greeter_server.cc.

Try it!

Build client and server:

$ make

Run the server, which will listen on port 50051:

$ ./greeter_server

Run the client (in a different terminal):

$ ./greeter_client

If things go smoothly, you will see the "Greeter received: Hello world" in the client side output.
