Can you provide the text of the errors as they are given? Are you
experiencing build errors, or are you wanting to quiet runtime
messages?

Which OS are you compiling and running on? Which build instructions
are you following? What are the build commands that you ran? Are you
using Clang, and is it necessary that you use Clang?

If we can't resolve your problem here it is possible I can refer you
to someone off-list, but I am not entirely sure what difficulty you
are having.
