When building Connector/ODBC from source, users now have a choice of linking dynamically or statically to the MySQL client library. Dynamic linking is selected by default. See Building Connector/ODBC from a Source Distribution on Windows or Building Connector/ODBC from a Source Distribution on Unix for details.
However, the binary distributions of Connector/ODBC from Oracle remain statically linked to the client library.
