Version 1.0.4 
mqtt_client_cpp is a header only library. It requires C++14 and the Boost Libraries 1.57.0 or later (See #33). The only feature that mqtt_client_cpp uses C++14 is binary literals. e.g.) 0b00001111
You may be able to use mqtt_client_cpp on C++11 with binary literal extension environment such as g++ and clang++.
Add mqtt_client_cpp/include to your include path. Then, include mqtt_client_cpp.hpp as follows:
#include <mqtt_client_cpp.hpp>You can compile your program as follows:
g++ -std=c++14 -Ipath_to_mqtt_client_cpp/include -DMQTT_NO_TLS no_tls.cpp -lboost_system -lpthread
g++ -std=c++14 -Ipath_to_mqtt_client_cpp/include tls.cpp -lboost_system -lssl -lcrypto -lpthread
See example/no_tls.cpp and example/tls.cpp
You can build tests and examples as follows:
At mqtt_client_cpp directory
mkdir build
cd build
cmake ..
make
make test
In order to build tests, you need to prepare the Boost Libraries 1.59.0.
