I’m on the second beta right now, sadly the problem still exists (I’m on Linux).

Used this command to fix:
protoc --gogoslick_out=. -I=. -I=${GOPATH}/src -I=${GOPATH}/src/github.com/gogo/protobuf/gogoproto *.proto

also my log.proto is updated:

syntax = "proto3";

package log.v1;

import "github.com/gogo/protobuf/gogoproto/gogo.proto";

option (gogoproto.marshaler_all) = true;
option (gogoproto.unmarshaler_all) = true;
option (gogoproto.sizer_all) = true;

message Record {
  bytes value = 1;
  uint64 offset = 2;
}

Hi,

I work on a mac and I had to use this command :

protoc api/v1/*.proto \
		--gogoslick_out=plugins=grpc:. \
		--proto_path=$$(go list -f '{{ .Dir }}' -m github.com/gogo/protobuf) \
		--proto_path=.

Notice the gogoslick_out flag. I had to use that instead of the gogo_out flag described in the book.

The readme file says :

protoc-gen-gogofast (same as gofast, but imports gogoprotobuf)
protoc-gen-gogofaster (same as gogofast, without XXX_unrecognized, less pointer fields)
protoc-gen-gogoslick (same as gogofaster, but with generated string, gostring and equal methods)

But indeed, I didn’t saw the last paragraph “Most Speed and most customization” describing the command you suggest.

So I guess, it’s not a matter of Mac or Linux. Maybe the gogo/protobuf changed is usage ?

To be fair, there is an old README in the git repo (https://github.com/gogo/protobuf/blob/master/README) descripting usage as

protoc --gogo_out=. -I=.:github.com/gogo/protobuf/protobuf *.proto

You didn’t have the second beta right? I believe I fixed this.
