google::protobuf:Message base class warning

[Billy Earney]

I'm running fedora 13, and I'm experiencing the following warnings when I compile drizzle (is any one else experiencing this?):

[Andrew Hutchings (linuxjedi)]

This is 'normal' since we do not error on these. Others may be better qualified to answer this but I believe it is a protobuf problem rather than something with Drizzle.

[Billy Earney (billy-earney)]

yes, I believe you are correct. I've done more research and found that others have this same problem cause the files are being generated by protoc. I have version 2.2.0. I'm guessing that is causing the issues.
