gRPC is a modern, open source, high-performance remote procedure call (RPC) framework that can run anywhere. gRPC enables client and server applications to communicate transparently, and simplifies the building of connected systems. This SlackBuild builds gRPC in C++. python3-grpcio contains the Python 3 build of gRPC. grpc is kept back at 1.80.0 on Slackware 15.0. The program version is meant to synchronize with python3-grpcio (which cannot be updated due to requiring Python >= 3.10).
