Questions tagged [protoc]

protoc is the compiler for .proto files. It generates language bindings for the messages and/or RPC services from .proto files. protoc is a native executable, the scripts under this directory build and publish a protoc executable (a.k.a. artifact) to Maven repositories. The artifact can be used by build automation tools so that users would not need to compile and install protoc for their systems.
