in reply to dmake.EXE: Error code 129, while making 'Oracle.o'

The problem is likely some lines upwards in the build failure. The output Oracle.c:2503: warning: unused variable 'Perl___notused' is just a warning and would not cause the build failure.

Please post more of the output, there should be a line with maybe Oracle.c:1234: error: at the start.

Note that Perl 5.14 is out of service since roughly 5 years ago. If you are starting to install modules, maybe it is a better idea to start with a more recent Perl like Strawberry Perl, which offers a 5.30 package for download.

    with strawberry perl version 5.30, DBD::Oracle gets installed like a charm.
    Glad that this error ended up having me latest version of Perl.
    Thanks
