Distributed programs that use the RPC paradigm

Programs

• registration - a client server program which implements a class registration platform. The program should allow the user to register themselves by entering their details which include the student registration number and names.
• calculator - a client server program which implements a simple calculator. The calculator can perform the following operations (+, -, *, /) chosen by the user on any two integers supplied by the user.

1. Install gRPC and Protobuf on your Linux system:

Step 1: Install the necessary dependencies:

sudo apt-get update
sudo apt-get install build-essential autoconf libtool pkg-config

Step 2: Install gRPC and Protobuf using apt:

sudo apt-get install libgrpc++-dev protobuf-compiler-grpc

Step 3: Install gRPC C++ Plugin:

sudo apt-get install grpc-compiler

2. Compile the Protobuf Files

• In the same directory as your program, run the following command to compile the Protobuf files:

 protoc --cpp_out=. --grpc_out=. --plugin=protoc-gen-grpc=`which grpc_cpp_plugin` filename.idl.proto

Replace 'filename' with the actual name of your file. This command generates the necessary C++ files (filename.idl.pb.h and filename.idl.grpc.pb.h) based on the Protobuf definition (filename.idl.proto).

3. Build the server

• Use a C++ compiler to build the server code and link against the required gRPC libraries. Assuming you have g++ installed, you can use the following command:

g++ -std=c++11 -o server server.cpp filename.idl.grpc.pb.cc filename.idl.pb.cc -lgrpc++ -lgrpc -lprotobuf -pthread

4. Build the client

g++ -std=c++11 -o client client.cpp filename.idl.grpc.pb.cc filename.idl.pb.cc -lgrpc++ -lgrpc -lprotobuf -pthread

5. Run the server

• Execute the server program in one terminal window:

./server

6. Run the client

• In another terminal window, execute the client program:

./client
