Alien::Util(3) User Contributed Perl Documentation Alien::Util(3)
NAME
Alien::Util - Alien Utilities used at build and runtime
VERSION
version 2.80
SYNOPSIS
use Alien::Util qw( version_cmp );
DESCRIPTION
This module contains some functions used by both the Alien::Build
build-time and <Alien::Base> run-time for Alien.
version_cmp
$cmp = version_cmp($x, $y)
Comparison method used by "atleast_version" in Alien::Base,
"exact_version" in Alien::Base and "max_version" in Alien::Base. May be
useful to implement custom comparisons, or for subclasses to overload
to get different version comparison semantics than the default rules,
for packages that have some other rules than the pkg-config behaviour.
Should return a number less than, equal to, or greater than zero;
similar in behaviour to the "<=>" and "cmp" operators.
