Protobuf: proto: undefined: proto.InternalMessageInfo

[sobhanthakur]

I am trying to compile lora-app-server source code. Whenever i run make command after make api. i get following errors

github.com/brocaar/lora-app-server/api
api/application.pb.go:89:46: undefined: proto.InternalMessageInfo
api/application.pb.go:170:47: undefined: proto.InternalMessageInfo
api/application.pb.go:209:43: undefined: proto.InternalMessageInfo
api/application.pb.go:262:44: undefined: proto.InternalMessageInfo
api/application.pb.go:362:46: undefined: proto.InternalMessageInfo

Any solution is welcome

The InternalMessageInfo type was added recently, so it means that your proto package has not been updated. You probably need to update the package:

go get -u github.com/golang/protobuf/proto

Keep in mind that vendoring directories may caused additional complications, so you'll have to check whether you're vendoring the proto package as well.

EDIT: Fixed package path.

I'm having the same issue. Updated protoc:

protoc --version
libprotoc 3.6.0

The generated .go file won't compile:

store/store.pb.go:78:27: undefined: proto.InternalMessageInfo
store/store.pb.go:312:28: undefined: proto.InternalMessageInfo
store/store.pb.go:387:25: undefined: proto.InternalMessageInfo
store/store.pb.go:685:28: undefined: proto.InternalMessageInfo
store/store.pb.go:783:28: undefined: proto.InternalMessageInfo
store/store.pb.go:849:29: undefined: proto.InternalMessageInfo
store/store.pb.go:889:30: undefined: proto.InternalMessageInfo
store/store.pb.go:946:26: undefined: proto.InternalMessageInfo
store/store.pb.go:1019:27: undefined: proto.InternalMessageInfo
store/store.pb.go:1059:29: undefined: proto.InternalMessageInfo
store/store.pb.go:1059:29: too many errors

Updating the package doesn't help:

# go get -u github.com/google/proto
package github.com/google/protobuf/proto: cannot find package "github.com/google/protobuf/proto" in any of:
    /usr/local/go/src/github.com/google/protobuf/proto (from $GOROOT)
    /go/src/github.com/google/protobuf/proto (from $GOPATH)

My mistake, it should be:

go get -u github.com/golang/protobuf/proto

Thanks, the problem was in old package in /vendor/github.com/golang/protobuf, just removed it, and the problem is gone

Great to hear.

运行glide get github.com/golang/protobuf,将protobuf放到glide依赖里面
