Hi, In GRPC examples, I deleted helloworld.pb.go and recreated it (after installing protoc-gen-go from "google.golang.org/protobuf" cmd):
xx:~/gopath/src/google.golang.org/grpc/examples/helloworld$ cd helloworld/ xx:~/gopath/src/google.golang.org/grpc/examples/helloworld/helloworld$ *protoc --go_out=. helloworld.proto * I then tried to build server and client binaries: xx:~/gopath/src/google.golang.org/grpc/examples/helloworld$ *go build -o server -v -a greeter_server/main.go * ... command-line-arguments # command-line-arguments greeter_server/main.go:39:2: undefined: helloworld.UnimplementedGreeterServer greeter_server/main.go:54:2: undefined: helloworld.RegisterGreeterServer xx:~/gopath/src/google.golang.org/grpc/examples/helloworld$ *go build -o client -v -a greeter_client/main.go * ... # command-line-arguments greeter_client/main.go:44:7: undefined: helloworld.NewGreeterClient Am I the only one seeing this issue? Did I make any mistake? Regards dharani On Fri, Apr 17, 2020 at 12:40 AM Tharaneedharan Vilwanathan < vdhar...@gmail.com> wrote: > Thank you all for the response.
