static verses dynamic linking with c++

[skolodzieski]

Every since around v1.5.0 we get undefined symbols when trying to use the shared library versions of librdkafka++. The static library does not have this issue. An example of the link errors are:

undefined reference to RdKafka::Producer::create(RdKafka::Conf const*, std::__cxx11::basic_string<char, std::char_traits, std::allocator >&)'`

undefined reference to RdKafka::KafkaConsumer::create(RdKafka::Conf const*, std::__cxx11::basic_string<char, std::char_traits, std::allocator >&)'`

Am I doing something wrong? I have commented on issue #3993, but it is 6 months old with no movement? I am wondering if we should recode our app to use the "c" library instead of the "c++" library? Does the "c++" wrappers get any attention?
