SYNOPSIS

11        $package = 'gtk+-2.0';
12
13        %pkg_info = ExtUtils::PkgConfig->find ($package);

16        print "libs:        $pkg_info{libs}\n";
17
18        $exists = ExtUtils::PkgConfig->exists($package);

DESCRIPTION

53       The pkg-config program retrieves information about installed libraries,
54       usually for the purposes of compiling against and linking to them.
55
56       ExtUtils::PkgConfig is a very simplistic interface to this utility,
57       intended for use in the Makefile.PL of perl extensions which bind
58       libraries that pkg-config knows.  It is really just boilerplate code
59       that you would've written yourself.
60
61   USAGE
62       HASH = ExtUtils::PkgConfig->find (STRING, [STRING, ...])
63           Call pkg-config on the library specified by STRING (you'll have to
64           know what to use here).  The returned HASH contains the modversion,
65           cflags, and libs values under keys with those names. If multiple
66           STRINGS are passed they are attempted in the order they are given
67           till a working package is found.
68
69           If pkg-config fails to find a working STRING, this function croaks
70           with a message intended to be helpful to whomever is attempting to
71           compile your package.
72
73           For example:
74
75             *** can not find package bad1
76             *** check that it is properly installed and available
77             *** in PKG_CONFIG_PATH
78
79           or
80
81             *** can't find cflags for gtk+-2.0
82             *** is it properly installed and available in PKG_CONFIG_PATH?
83
84       STRING = ExtUtils::PkgConfig->create_version_macros (PACKAGE, STEM)
85           Create a set of version macros with the prefix STEM for the library
86           specified by PACKAGE.  The result is returned.
87
88           Example input would be "gtk+-2.0" for PACKAGE and "GTK" for STEM.
89
90       ExtUtils::PkgConfig->write_version_macros (FILE, PACKAGE, STEM,
91       [PACKAGE, STEM, ...])
92           Create one or more sets of version macros for the libraries and
93           prefixes specified by the PACKAGE and STEM pairs and write them to
94           the file FILE.  If it doesn't exist, FILE will be created.  If it
95           does exist, it will be overwritten.

SEE ALSO

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