proto3 syntax is not identified as proper syntax only proto2

[moadqassem]

| have installed the plugin in my $GOPATH in order to give it a go, and I have created a .proto file with proto3 syntax where I got rid of all the required keywords and started the file with ' syntax="proto3" ', however I keep getting this compilation error message:

" Unrecognized syntax identifier "proto3". This parser only recognizes "proto2"."

P.S: when I change from proto3 to proto2 the compilation succeeded however I have of course to invoke the required keywords again because this feature is not supported in proto2.

Your protoc is out of date. You need to update it.

I see but how can update exactly, I mean I have executed what it's written in the steps and to get everything runs I should execute this command line:

go get -u github.com/golang/protobuf/{proto,protoc-gen-go}

is there any extra steps?

[dsymonds]

No, that's only the Go parts. You need to update your protoc from https://github.com/google/protobuf.

I got this message with the "latest" protoc from here:

https://developers.google.com/protocol-buffers/docs/downloads

I didn't notice that that version is from 2014. You might want to update it!

Acknowledged. Following up to try to get that link updated.
