I am trying to test my ODBC connection in Teradata on UNIX using adhoc file.

teradata/client/17.10/odbc_64/samples/C/adhoc

when trying to connect to Oracle DSN, I get following error

 adhoc: (SQL Diagnostics) STATE=IM003, CODE=0, MSG=[DataDirect][ODBC lib] Specifi                                                                                                                                                      ed driver could not be loaded
    No driver entry found under the DSN :
