echo service example does not compile

Can't reproduce.

Another possible guess is that your protoc-gen-go is out-of-date. What happens if you run go get -u github.com/golang/protobuf/protoc-gen-go then try it again?

[yugui]

I guess the revision of google.golang.org/grpc you have is inconsistent to the example.
Could you try running go get -u google.golang.org/grpc to update the revision?

I'm on 0e69ad1, so latest master.

[diogomonica]

It seems to build now. Probably screwed up along somewhere. Thank you.

The generated protos that are currently in the repository work, but when regenerating using the instructions:

➜ protoc -I/usr/local/include -I. \
 -I$GOPATH/src \     
 -I$GOPATH/src/github.com/gengo/grpc-gateway/third_party/googleapis \
 --go_out=Mgoogle/api/annotations.proto=github.com/gengo/grpc-gateway/third_party/googleapis/google/api,plugins=grpc:. echo_service.proto
➜ protoc -I/usr/local/include -I. \
 -I$GOPATH/src \     
 -I$GOPATH/src/github.com/gengo/grpc-gateway/third_party/googleapis \
 --grpc-gateway_out=logtostderr=true:. echo_service.proto

Using protoc:

➜  protoc --version
libprotoc 3.0.0

And with go-grpc on 0e69ad1 (master) from 9 hours ago, and grpc-gateway on 67e1374 (master), I still get:

➜  go build
