Hi, Firstly, 5432 is PostgreSQL. MySQL/MariaDB default port is 3306. Just a note, as mysql_init() only allocates the C level structure and doesn't connect. > FFILibrary subclass: #MariaDBLibC > > FFIOpaqueObject subclass: #MariaDBHandle > MariaDBHandle >> unixModuleName [ > ^ '/usr/lib/x86_64-linux-gnu/libmariadb.so' > ] With your code, implementing #unixModuleName in MariaDBLibC works for me. I've never done that in FFIOpaqueObject subclasses. In terms of organizing code, suggest you implement the FFI calls in MariaDBLibC itself and do away with MariaDBDriver. Having the FFI calls in MariaDBDriver while using MariaDBLibC only for locating the C libraries is using two classes where one will do. Finally, there is a non FFI pure Smalltalk implementation of the MySQL wire protocol that has been around a while. If you are doing this FFI thing for practice, I recommend that you wrap another C library, so that when you are done, Pharo gets another C library binding. https://github.com/pharo-rdbms/Pharo-MySQL Pierce
