Prerequisite
The ODBC technology relies on a driver manager that is used as an interface between applications (like mmodbc) and a data source itself accessed through a dedicated driver. As a consequence, this module requires that both, a driver manager and the necessary drivers (one for each data source to be used), are installed and set up on the operating system.
Under Windows, usually the driver manager is part of the system and most data sources are provided with their ODBC driver (for instance Excel, Access or SQLServer).
On the other supported operating systems it may be necessary to install a driver manager (as well as the necessary drivers). The module mmodbc supports two driver managers: iODBC (http://www.iodbc.org) and unixODBC (http://www.unixodbc.org). Upon startup the module tries to load the dynamic library "libiodbc.so" then, if this fails, tries "libodbc.so". If none of these libraries can be found only the SQLite integrated driver will be available, please make sure that one of the driver managers is installed and that the corresponding libraries can be accessed (in general this requires updating some environment variable).
