DESCRIPTION

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

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