The source of the code calculations of entropy is available, you can use it directly on your code, there is also a compiled static library.
There is a consumer code for using with redis and the k_v_store_benchmark to test the entropy.
This work is a C++ version of the algorithm that was already implemented in Java on this repository: https://github.com/blazs/DataStreamAlgorithms
