The Qpid Proton sample applications that demonstrate multi-threaded operation do not build on a RHEL 6.5 system.

$ g++ --std=c++11 multithreaded_client.cpp -lqpid-proton-cpp
undefined reference to `proton::work_queue::add(proton::internal::v11::work)'
...

Looking inside the version of libqpid-proton-cpp.so distributed for RHEL 6.5, I see:

proton::work_queue::add(proton::internal::v03::work)

It looks as if the RHEL 6.5 version of Qpid Proton lacks some C++11 support.

I am unsure whether the failing here is in the example, or the Qpid build distributed for RHEL 6.5.
