Warning messages when building from source

[wnq]

When I build Dynomite from source on my RHEL 7 (see detail below) I am getting some warning messages that are concerning. I am attaching the entire make output if that helps.

My question is if there is any way to get a clean build, such as additional options/switches, an optimal platform on which to do the build or enhancing the source to suppress the warnings?
