The following steps are required to write a gRPC application in C++:

  1. install the C++ plugins for gRPC and Protocol Buffers
  2. To install the C++ plugins for gRPC and Protocol Buffers, you can use the following commands:
    $ sudo apt-get install -y build-essential autoconf libtool pkg-config
    $ sudo apt-get install -y libgflags-dev libgtest-dev
    $ sudo apt-get install -y clang libc++-dev
    $ git clone -b $(curl -L https://grpc.io/release) https://github.com/grpc/grpc
    $ cd grpc
    $ git submodule update –init
    $ make grpc_cpp_plugin
    $ sudo make install
  3. Write a .proto file.
  4. Define interfaces and message structures using Protocol Buffers language, and save as .proto file.
  5. Create C++ code.
  6. Generate C++ code using Protocol Buffers plugin:
    $ protoc -I=./ –cpp_out=./ .proto
    $ protoc -I=./ –grpc_out=./ –plugin=protoc-gen-grpc=`which grpc_cpp_plugin` .proto
  7. Write gRPC server code:
  8. Implement the service interface generated from the .proto file and start the gRPC server.
  9. Write code for a gRPC client:
  10. Create a gRPC client and invoke methods provided by the server.
  11. Build and execute applications.
  12. Compile the server and client code, and then run the generated executable file.

The above are the basic steps for developing a gRPC application using C++, which can be adjusted and expanded according to actual needs. Detailed documentation and examples can be found on the official gRPC website.
