NAME

6       PkgConfig::LibPkgConf - Interface to .pc file interface via libpkgconf
7

SYNOPSIS

9        use PkgConfig::LibPkgConf;
10
11        if(pkgconf_exists('libarchive'))
12        {
13          my $version = pkgconf_version('libarchive');
14          my $cflags  = pkgconf_cflags('libarchive');
15          my $libs    = pkgconf_libs('libarchive');
16        }
17

DESCRIPTION

19       Many libraries in compiled languages such as C or C++ provide ".pc"
20       files to specify the flags required for compiling and linking against
21       those libraries.  Traditionally, the command line program "pkg-config"
22       is used to query these files.  This module provides a Perl level API
23       using "libpkgconf" to these files.
24
25       This module provides a simplified interface for getting the existence,
26       version, cflags and library flags needed for compiling against a
27       package, using the default compiled in configuration of "pkgconf".  For
28       a more powerful, but complicated interface see
29       PkgConfig::LibPkgConf::Client.  In addition,
30       PkgConfig::LibPkgConf::Util provides some useful utility functions that
31       are also provided by "pkgconf".

FUNCTIONS

34   pkgconf_exists
35        my $bool = pkgconf_exists $package_name;
36
37       Returns true if the package is available.
38
39       Exported by default.
40
41   pkgconf_version
42        my $version = pkgconf_version $package_name;
43
44       Returns the version of the package, if it exists.  Will throw an
45       exception if not found.
46
47       Exported by default.
48
49   pkgconf_cflags
50        my $cflags = pkgconf_cflags $package_name;
51
52       Returns the compiler flags for the package, if it exists.  Will throw
53       an exception if not found.
54
55       Exported by default.
56
57   pkgconf_cflags_static
58        my $cflags = pkgconf_cflags_static $package_name;
59
60       Returns the static compiler flags for the package, if it exists.  Will
61       throw an exception if not found.
62
63   pkgconf_libs
64        my $libs = pkgconf_libs $package_name;
65
66       Returns the linker library flags for the package, if it exists.  Will
67       throw an exception if not found.
68
69       Exported by default.
70
71   pkgconf_libs_static
72        my $libs = pkgconf_libs_static $package_name;
73
74       Returns the static linker library flags for the package, if it exists.
75       Will throw an exception if not found.

SEE ALSO

89       The best entry point to the low level "pkgconf" interface can be found
90       via PkgConfig::LibPkgConf::Client.
91
92       Alternatives include:
93
94       PkgConfig
95           Pure Perl implementation of "pkg-config" which can be used from the
96           command line, or as an API from Perl.  Does not require pkg-config
97           in your path, so is a safe dependency for CPAN modules.
98
99       ExtUtils::PkgConfig
100           Wrapper for the "pkg-config" command line interface.  This module
101           will fail to install if "pkg-config" cannot be found in the "PATH",
102           so it is not safe to use a dependency if you want your CPAN module
103           to work on platforms where "pkg-config" is not installed.
104
105       Alien::Base
106           Provides tools for building non-Perl libraries and making them
107           dependencies for your CPAN modules, even on platforms where the
108           non-Perl libraries aren't already installed.  Includes hooks for
109           probing "pkg-config" ".pc" files using either "pkg-config" or
110           PkgConfig.
