Hmmm ... I think that perl was built using an older MS compiler.
However, I'm inclined to think that shouldn't matter, and it's certainly appropriate to be using an MS compiler to build modules for that perl build that you have.
How did you try to build DBD::MariaDB ? A normal way would have been to run cpan -i DBD::MariaDB .

The error message you posted in your original post doesn't provide anything meaningful to me. It's very strange that the standard Windows headers windows.h and winsock.h (included with every MS compiler) could not be found.
Did you run the VC++ batch file that sets up the environment such that these headers are found by default ?

Or perhaps the problem is just some stupid checks that the DBD::MariaDB Makefile.PL wants to run. (I haven't looked.)
Sorry - I don't mess much with VC++ builds of perl any more, and I don't mess with DBD/DBI modules at all.
If I needed to get this done, I'd just grab one of the "Portable" Strawberry Perl builds from https://strawberryperl.com/releases.html, as that seems so simple and straightforward.

Cheers,
Rob
