Compliance

Note that many Linux ODBC drivers (PostgreSQL, for example) are still only ODBC 2 compliant and therefore will not work directly without a driver manager.

The use of an ODBC 3 driver manager will solve this problem.

Build Issues

If you are using Kylix 1 and it has stopped working with build 1.0.18 of the Easysoft dbExpress-ODBC Gateway, then please contact Easysoft via support@easysoft.com to obtain an alternative build, as version 1.0.18 has been linked to work with Kylix 2 only.

Note that this restriction with Kylix 1 is only present in the trial driver, because of the need to create a splash screen.

Connectivity

The Easysoft dbExpress-ODBC Gateway has been used succesfully with the following drivers:

If you have successfully used other drivers, please let us know and they will be added to this list.
