![]() So now we need to install the gRPC and Protobuf packages in our system. GRPC plugin for the specific language: Separate gRPC plugins exist for different programming languages and these will be required by the protoc for generating the source files based on the service interfaces defined on the IDL. proto file is an IDL file where we define the message passing structures and rpc apis according to the Protobuf specifications. Protoc is a compiler which will take the proto file as the input and generates the message structs and service interfaces in the desired language, in our case, C++. The following components are required for generating the message structures and the service interfaces , Let's take an example with C++ as the language for the server and client. gRPC uses protocol buffers as the Interface Definition Language (IDL) for describing both the service interface and the structure of the payload messages. gRPC has support for multiple languages and as a result, you can easily make your C++ app to communicate with a Go or Python app, by making use of a common Interface Definition Language(IDL) file. This is very useful if you are developing prototypes and you want to make them communicate with each other. As a result, the developer can easily make multiple programs talk to each other over a network without going through the hassles of networking programming. It does it by conveniently abstracting the complexities of enabling server/client connections from the developer and reducing it to simple remote procedure calls. GRPC is an RPC framework provided by Google to enable communication between multiple applications over a network. Here in this article, I'll show you how to set up grpc, protobuf libraries in Windows and to make a simple hello world program using server-client model. Now it is slowly changing with the advent of new ones such as vcpkg or conan. Also C++ lacked a widely used stable package manager for a long time. On the contrary, if you're in a Linux/macOS environment, it will mostly reduce to a couple of make and make install commands. If there is no prebuilt binary for a specific library, then you will find yourself in the hell hole of compiling it in Windows and also their dependencies. Working with open source projects using C/C++, in Windows has always been a pain, especially for beginners.
