Alien::Build::Plugin::PkgConfig::LibPkgConf - Probe system and determine library or tool properties using PkgConfig::LibPkgConf


version 2.83


 use alienfile;
 plugin 'PkgConfig::LibPkgConf' => (
   pkg_name => 'libfoo',


Note: in most case you will want to use Alien::Build::Plugin::PkgConfig::Negotiate instead. It picks the appropriate fetch plugin based on your platform and environment. In some cases you may need to use this plugin directly instead.

This plugin provides Probe and Gather steps for pkg-config based packages. It uses PkgConfig::LibPkgConf to accomplish this task.

This plugin is part of the Alien::Build core For Now, but may be removed in a future date. While It Seemed Like A Good Idea at the time, it may not be appropriate to keep it in core. If it is spun off it will get its own distribution some time in the future.



The package name. If this is a list reference then .pc files with all those package names must be present. The first name will be the primary and used by default once installed. For the subsequent .pc files you can use the Alien::Base alt method to retrieve the alternate configurations once the Alien is installed.


The minimum required version that is acceptable version as provided by the system.


The exact required version that is acceptable version as provided by the system.


The max required version that is acceptable version as provided by the system.


Alias for atleast_version for backward compatibility.



 my $bool = Alien::Build::Plugin::PkgConfig::LibPkgConf->available;

Returns true if the necessary prereqs for this plugin are already installed.
