PkgConfig::LibPkgConf - Interface to .pc file interface via libpkgconf
use PkgConfig::LibPkgConf;
if(pkgconf_exists('libarchive'))
{
my $version = pkgconf_version('libarchive');
my $cflags = pkgconf_cflags('libarchive');
my $libs = pkgconf_libs('libarchive');
}
Many libraries in compiled languages such as C or C++ provide .pc files to specify the flags required for compiling and linking against those libraries. Traditionally, the command line program pkg-config is used to query these files. This module provides a Perl level API using libpkgconf to these files.
This module provides a simplified interface for getting the existence, version, cflags and library flags needed for compiling against a package, using the default compiled in configuration of pkgconf. For a more powerful, but complicated interface see PkgConfig::LibPkgConf::Client. In addition, PkgConfig::LibPkgConf::Util provides some useful utility functions that are also provided by pkgconf.
my $bool = pkgconf_exists $package_name;
Returns true if the package is available.
Exported by default.
my $version = pkgconf_version $package_name;
Returns the version of the package, if it exists. Will throw an exception if not found.
Exported by default.
my $cflags = pkgconf_cflags $package_name;
Returns the compiler flags for the package, if it exists. Will throw an exception if not found.
Exported by default.
my $cflags = pkgconf_cflags_static $package_name;
Returns the static compiler flags for the package, if it exists. Will throw an exception if not found.
my $libs = pkgconf_libs $package_name;
Returns the linker library flags for the package, if it exists. Will throw an exception if not found.
Exported by default.
my $libs = pkgconf_libs_static $package_name;
Returns the static linker library flags for the package, if it exists. Will throw an exception if not found.

The best entry point to the low level pkgconf interface can be found via PkgConfig::LibPkgConf::Client.
Alternatives include:
Pure Perl implementation of pkg-config which can be used from the command line, or as an API from Perl. Does not require pkg-config in your path, so is a safe dependency for CPAN modules.
Wrapper for the pkg-config command line interface. This module will fail to install if pkg-config cannot be found in the PATH, so it is not safe to use a dependency if you want your CPAN module to work on platforms where pkg-config is not installed.
Provides tools for building non-Perl libraries and making them dependencies for your CPAN modules, even on platforms where the non-Perl libraries aren't already installed. Includes hooks for probing pkg-config .pc files using either pkg-config or PkgConfig.
