Calculator example

This example demonstrates how to use ZserioServiceGrpc library to use gRPC server-client communication.

Prerequisites

  1. Prerequisites for ZserioServiceGrpc,

Note that Zserio prerequisites are automatically downloaded by CMake.

Building

Make sure that PREFIX_PATH is set correctly to gRPC installation. For example, if doc/BUILD_gRPC.md has been used, set the following:

PREFIX_PATH="/opt/tools/gRPC/lib/cmake;/opt/tools/protobuf/lib/cmake"
PREFIX_PATH+=";/opt/tools/cares/lib/cmake;/opt/tools/abseil/lib/cmake"

Go to the calculator example directory.

mkdir build
pushd build
cmake -DCMAKE_PREFIX_PATH="${PREFIX_PATH}" ..
cmake --build .
popd

Note that for MSVC compiler, you might need to specify configuration by cmake --build . --config Release or cmake --build . --config Debug.

Testing

Go to the build directory where executables are located.

./CalculatorServer &
./CalculatorClient
# follow client's instructions
# ...
# press q + ENTER to quit the client
fg # and press Ctrl+C to quit the server
