How to create a C++ gRPC application

Start by copying the hello world example and compiling it (instructions here). The compilation steps differ slightly between examples.

cd <my_gRPC_dir>
mkdir ejfat
cd ejfat
mkdir cpp protos

cp /daqfs/gRPC/grpc/examples/protos/helloworld.proto protos/.
cp -r /daqfs/gRPC/grpc/examples/cpp/cmake cpp/.
cp -r /daqfs/gRPC/grpc/examples/cpp/helloworld cpp/.

cd cpp/helloworld
mkdir -p cmake/build
cd cmake/build
cmake -DCMAKE_PREFIX_PATH=$GRPC_INSTALL_DIR -DBUILD_SHARED_LIBS=ON ../..
make -j 4

Now modify the code to suit.

The application in this case is the reporting to the control plane of the fill level of an ERSAP backend reassembler's fifo.
