DESCRIPTION
The pkg-config program retrieves information about installed libraries,
usually for the purposes of compiling against and linking to them.
ExtUtils::PkgConfig is a very simplistic interface to this utility,
intended for use in the Makefile.PL of perl extensions which bind
libraries that pkg-config knows. It is really just boilerplate code
that you would've written yourself.
USAGE
HASH = ExtUtils::PkgConfig->find (STRING, [STRING, ...])
Call pkg-config on the library specified by STRING (you'll have to
know what to use here). The returned HASH contains the modversion,
cflags, and libs values under keys with those names. If multiple
STRINGS are passed they are attempted in the order they are given
till a working package is found.
If pkg-config fails to find a working STRING, this function croaks
with a message intended to be helpful to whomever is attempting to
compile your package.
For example:
*** can not find package bad1
*** check that it is properly installed and available
*** in PKG_CONFIG_PATH
or
*** can't find cflags for gtk+-2.0
*** is it properly installed and available in PKG_CONFIG_PATH?
STRING = ExtUtils::PkgConfig->create_version_macros (PACKAGE, STEM)
Create a set of version macros with the prefix STEM for the library
specified by PACKAGE. The result is returned.
Example input would be "gtk+-2.0" for PACKAGE and "GTK" for STEM.
ExtUtils::PkgConfig->write_version_macros (FILE, PACKAGE, STEM,
[PACKAGE, STEM, ...])
Create one or more sets of version macros for the libraries and
prefixes specified by the PACKAGE and STEM pairs and write them to
the file FILE. If it doesn't exist, FILE will be created. If it
does exist, it will be overwritten.
SEE ALSOExtUtils::PkgConfig was designed to work with ExtUtils::Depends for
compiling the various modules of the gtk2-perl project.
