- Setup some environmental variables (assuming bash)
export GRPC_INSTALL_DIR=/daqfs/gRPC/installation export PATH="$GRPC_INSTALL_DIR/bin:$PATH" export LD_LIBRARY_PATH="$GRPC_INSTALL_DIR/lib:$LD_LIBRARY_PATH"
- Start by copying the hello world example and compiling it (official 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=$GRPC_INSTALL_DIR -DBUILD_SHARED_LIBS=ON ../.. make -j 4
- Rename a few files and directories, from helloworld to loadBalancerControl (or whatever you want)
cd <my_gRPC_dir>/ejfat mv protos/helloworld.proto protos/loadBalancerControl.proto mv cpp/helloworld cpp/loadBalancerControl
- As an example, make changes to code which implements ERSAP backend reassembler communicating fifo fill percentage to load-balancer control plane
cd cpp/loadBalancerControl rm -fr cmake mkdir -p cmake/build cd cmake/build cmake -DCMAKE_PREFIX_PATH=$GRPC_INSTALL_DIR -DBUILD_SHARED_LIBS=ON ../.. make -j 4
The application in this case is the reporting to the control plane of the fill level of an ERSAP backend reassembler's fifo.
