The ODBC Driver can be used with the unixODBC Driver Manager on non-Windows platforms. Unlike the ODBC CLI, the unixODBC Driver Manager allows other ODBC drivers to be used in addition to the Ingres/Vector ODBC driver. To build the application, the include files sql.h and sqlext.h files in $II_SYSTEM/ingres/files can be used; alternatively, the include files sql.h, sqlext.h, sqltypes.h, and sqlucode.h provided with the unixODBC installation can be used.

UnixODBC data sources can be configured using the Ingres ODBC Administrator, just as for the ODBC CLI. Unlike the CLI, the ODBCINI and ODBCSYSINI environment variables must be specified if the locations for the odbc.ini and odbcinst.ini files differ from the default locations. For more information about ODBCINI and ODBCSYSINI in the unixODBC environment, see the unixODBC documentation.

Linux: Here is an example for building a unixODBC application on Linux:
