Hello Michael! I am not sure what the actual problem here is. What are you trying to achieve which does not work? What is the name of the software that fails to compile with MariaDB, either using libmariadbclient-dev, libmariadbclient-dev-compat, libmariadb-dev or libmariadb-dev-compat?
To my knowledge all scenarios are covered, no matter if you develop new code against the MariaDB Connector or if you build existing MySQL linking stuff uisng the -compat packages, all options should work. - Otto
