ExtUtils::MM(3) Perl Programmers Reference Guide ExtUtils::MM(3) NAME ExtUtils::MM - OS adjusted ExtUtils::MakeMaker subclass SYNOPSIS require ExtUtils::MM; my $mm = MM->new(...); DESCRIPTION FOR INTERNAL USE ONLY ExtUtils::MM is a subclass of ExtUtils::MakeMaker which automatically chooses the appropriate OS specific subclass for you (ie. ExtU- tils::MM_Unix, etc...). It also provides a convenient alias via the MM class (I didn't want Make- Maker modules outside of ExtUtils/). This class might turn out to be a temporary solution, but MM won't go away. perl v5.44.0 2026-06-22 ExtUtils::MM(3)
