module.proto:30:3: "google.protobuf.Timestamp" is not defined.

This message leads to compiler failing to compile stubs.

message SignupEntity {
  SignupEntityStatus status = 1;
  google.protobuf.Timestamp status_time = 2;
}

I have this note taken earlier:

In order to compile protobufs, /usr/local/include should be populated with protocolbuffers/protobuf.
Copy include/google/protobuf directory from downloaded archive into /usr/local/include/google

But seems that is not the case there and... it looks to me that in latest protocolbuffers versions there is some changes when installing compiler.

Ok, seems that PATH=$PATH:~/usr/local/include was the missing piece.

Leaving for the future me

export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PROTOC=/usr/local/include
export PATH=$PATH:$GOROOT:$GOPATH:$GOBIN:$PROTOC

Or just the missing restart/ source. Removed /usr/local/include from path and seems it still works even after restart, Not sure what was the cause.
