Steps to take in creating a gRPC application from an example in the C++ gRPC package.


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

Start by copying the hello world example as it's the simplest and does what we want
cd /daqfs/gRPC
mkdir ejfat
cd ejfat
mkdir cpp protos

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

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