MySQL Connector/ODBC 8.0 on Linux

Oracle's MySQL server can be connected and used with ODBC driver in a similar fashion that we have discussed for Microsoft's MsSQL server in the previous post. For that, we will use the latest MySQL Connector/ODBC 8.0 driver by building and installing it from the source.

Therefore, the procedure can be used for various SBCs with different architectures. An advantage for this approach is that we can use the same C++ code for both MsSQL server and MySQL server just by changing the DSN. At first, following tools need to be installed in the machine.
sudo apt install mysql-client libmysqlclient-dev
sudo apt install unixodbc unixodbc-dev
sudo apt install libgtk-3-dev cmake
sudo apt install libssl-dev
