Hence, tried C++ Connector installation from source as in the following: (Installed Boost/CMake/Make) successfully. However, got stuck with the "make clean" step, refer to the following:

https://dev.mysql.com/doc/connector-cpp/en/connector-cpp-installation-source-prerequisites.html

Boost is installed:

Please help fix the error.

In a nutshell, how to connect to MySQL using g++/c++ and (not VC++) on Windows without any IDE, the development "environment" being Git Bash/Notepad/MySQL 5.7.14, for Win64 (x86_64)

Thanks
