## Installation |
|
|
|
To install gRPC on your system, follow the instructions here: |
|
[https://github.com/grpc/grpc/blob/master/INSTALL](https://github.com/grpc/grpc/blob/master/INSTALL). |
|
|
|
## Hello C++ gRPC! |
|
|
|
Here's how to build and run the C++ implementation of the [Hello World](https://github.com/grpc/grpc-common/blob/master/protos/helloworld.proto) example used in [Getting started](https://github.com/grpc/grpc-common). |
|
|
|
The example code for this and our other examples lives in the `grpc-common` |
|
GitHub repository. Clone this repository to your local machine by running the |
|
following command: |
|
|
|
|
|
```sh |
|
$ git clone https://github.com/grpc/grpc-common.git |
|
``` |
|
|
|
Change your current directory to grpc-common/cpp/helloworld |
|
|
|
```sh |
|
$ cd grpc-common/cpp/helloworld/ |
|
``` |
|
|
|
|
|
### Generating gRPC code |
|
|
|
To generate the client and server side interfaces: |
|
|
|
```sh |
|
$ make helloworld.grpc.pb.cc helloworld.pb.cc |
|
``` |
|
Which internally invokes the proto-compiler as: |
|
|
|
```sh |
|
$ protoc -I ../../protos/ --grpc_out=. --plugin=protoc-gen-grpc=grpc_cpp_plugin ../../protos/helloworld.proto |
|
$ protoc -I ../../protos/ --cpp_out=. ../../protos/helloworld.proto |
|
``` |
|
|
|
### Client and server implementations |
|
|
|
The client implementation is at [greeter_client.cc](https://github.com/grpc/grpc-common/blob/master/cpp/helloworld/greeter_client.cc). |
|
|
|
The server implementation is at [greeter_server.cc](https://github.com/grpc/grpc-common/blob/master/cpp/helloworld/greeter_server.cc). |
|
|
|
### Try it! |
|
Build client and server: |
|
```sh |
|
$ make |
|
``` |
|
Run the server, which will listen on port 50051: |
|
```sh |
|
$ ./greeter_server |
|
``` |
|
Run the client (in a different terminal): |
|
```sh |
|
$ ./greeter_client |
|
``` |
|
If things go smoothly, you will see the "Greeter received: Hello world" in the client side output. |
