SYNOPSIS

9        use ExtUtils::PkgConfig;
10
11        $package = 'gtk+-2.0';
12
13        %pkg_info = ExtUtils::PkgConfig->find ($package);
14        print "modversion:  $pkg_info{modversion}\n";
15        print "cflags:      $pkg_info{cflags}\n";
16        print "libs:        $pkg_info{libs}\n";
17
18        $modversion = ExtUtils::PkgConfig->modversion($package);
19
20        $libs = ExtUtils::PkgConfig->libs($package);
21
22        $cflags = ExtUtils::PkgConfig->cflags($package);
23
24        $lib_only_L = ExtUtils::PkgConfig->libs_only_L($package);
25
26        $lib_only_l = ExtUtils::PkgConfig->libs_only_l($package);
27
28        $var_value = ExtUtils::PkgConfig->variable($package,$var);
29
30        if (ExtUtils::PkgConfig->atleast_version($package,$version)) {
31           ...
32        }
33
34        if (ExtUtils::PkgConfig->exact_version($package,$version)) {
35           ...
36        }

DESCRIPTION

43       The pkg-config program retrieves information about installed libraries,
44       usually for the purposes of compiling against and linking to them.
45
46       ExtUtils::PkgConfig is a very simplistic interface to this utility,
47       intended for use in the Makefile.PL of perl extensions which bind
48       libraries that pkg-config knows.  It is really just boilerplate code
49       that you would've written yourself.
50
51       USAGE
52
53       HASH = ExtUtils::PkgConfig->find (STRING, [STRING, ...])
54           Call pkg-config on the library specified by STRING (you'll have to
55           know what to use here).  The returned HASH contains the modversion,
56           cflags, and libs values under keys with those names. If multiple
57           STRINGS are passed they are attempted in the order they are given
58           till a working package is found.
59
60           If pkg-config fails to find a working STRING, this function croaks
61           with a message intended to be helpful to whomever is attempting to
62           compile your package.
63
64           For example:
65
66             *** can not find package bad1
67             *** check that it is properly installed and available
68             *** in PKG_CONFIG_PATH
69
70           or
71
72             *** can't find cflags for gtk+-2.0
73             *** is it properly installed and available in PKG_CONFIG_PATH?
74
75       STRING = ExtUtils::PkgConfig->create_version_macros (PACKAGE, STEM)
76           Create a set of version macros with the prefix STEM for the library
77           specified by PACKAGE.  The result is returned.
78
79           Example input would be "gtk+-2.0" for PACKAGE and "GTK" for STEM.
80
81       ExtUtils::PkgConfig->write_version_macros (FILE, PACKAGE, STEM, [PACK‐
82       AGE, STEM, ...])
83           Create one or more sets of version macros for the libraries and
84           prefixes specified by the PACKAGE and STEM pairs and write them to
85           the file FILE.  If it doesn't exist, FILE will be created.  If it
86           does exist, it will be overwritten.

SEE ALSO

89       ExtUtils::PkgConfig was designed to work with ExtUtils::Depends for
90       compiling the various modules of the gtk2-perl project.
