Typically, setting up a C++ gRPC environment involves the following steps:

  1. To install the gRPC C++ plugin, you will need to first download the source code from GitHub and compile it using the following command.
git clone -b v1.38.1 https://github.com/grpc/grpc
cd grpc
git submodule update --init
mkdir -p cmake/build
cd cmake/build
cmake -DgRPC_INSTALL=ON -DgRPC_BUILD_TESTS=OFF -DCMAKE_INSTALL_PREFIX=<path_to_install> ../..
make -j
make install

The refers to the installation path and can be adjusted according to your needs.

  1. Write code for gRPC service and client. Define a .proto file and generate corresponding code using the protoc tool. An example .proto file is provided below:
syntax = "proto3";

package helloworld;

service Greeter {
  rpc SayHello (HelloRequest) returns (HelloReply) {}
}

message HelloRequest {
  string name = 1;
}

message HelloReply {
  string message = 1;
}
  1. Generate code
    Use the protoc tool to generate the corresponding code.
protoc -I=. --grpc_out=. --plugin=protoc-gen-grpc=`which grpc_cpp_plugin` helloworld.proto
protoc -I=. --cpp_out=. helloworld.proto
  1. Write code for services and clients, using the generated code to communicate.
  2. Compile and execute
    Compile the service and client code, link to the gRPC library for compilation, and then run the generated executable file.

By following the above steps, you can set up and use a C++ gRPC environment.
