PkgConfig::LibPkgConf::Client - Query installed libraries for compiling and linking software
use PkgConfig::LibPkgConf::Client; my $client = PkgConfig::LibPkgConf::Client->new; $client->env; my $pkg = $client->find('libarchive'); my $cflags = $pkg->cflags; my $libs = $pkg->libs;
The PkgConfig::LibPkgConf::Client objects store all necessary state for libpkgconf allowing for multiple instances to run in parallel.
libpkgconf
my $client = PkgConfig::LibPkgConf::Client->new(%opts); my $client = PkgConfig::LibPkgConf::Client->new(\%opts);
Creates an instance of PkgConfig::LibPkgConf::Client. Possible options include:
The search path to look for .pc files. This may be specified either as a string with the appropriate path separator character, or as a list reference. This will override the pkgconf compiled in defaults and the environment variables for PKG_CONFIG_PATH or PKG_CONFIG_LIBDIR.
.pc
pkgconf
PKG_CONFIG_PATH
PKG_CONFIG_LIBDIR
List of directories to filter for libraries. This overrides the pkgconf compiled in default and environment variable for PKG_CONFIG_SYSTEM_LIBRARY_PATH.
PKG_CONFIG_SYSTEM_LIBRARY_PATH
List of directories to filter for include. This overrides the pkgconf compiled in default and environment variable for PKG_CONFIG_SYSTEM_INCLUDE_PATH.
PKG_CONFIG_SYSTEM_INCLUDE_PATH
environment variables honored:
my @path = $client->path;
The search path to look for .pc files.
my @dirs = $client->filter_lib_dirs;
List of directories to filter for libraries.
my @dirs = $client->filter_include_dirs;
List of directories to filter for includes.
my $dir = $client->sysroot_dir; $client->sysroot_dir($dir);
Get or set the sysroot directory.
my $dir = $client->buildroot_dir; $client->buildroot_dir($dir);
Get or set the buildroot directory.
my $int = $client->maxdepth; $client->maxdepth($int);
Get or set the maximum dependency depth. This is 2000 by default.
my $client->env;
This method loads settings for the client object from the environment using the standard pkg-config or pkgconf environment variables. It honors the following list of environment variables:
pkg-config
my $pkg = $client->find($package_name);
Searches the <.pc> file for the package with the given $package_name. If found returns an instance of PkgConfig::LibPkgConf::Package. If not found returns undef.
$package_name
undef
my $pkg = $client->package_from_file($filename);
Load the specific <.pc> file.
$client->scan_all(sub { my($client, $package) = @_; ... return $bool; });
Iterates through all packages and calls the given subroutine reference for each package. $package isa PkgConfig::LibPkgConf::Package. The scan will continue so long as a non true value is returned (as $bool).
$package
$bool
$client->global($key => $value); my $value = $client->global($key);
Define or get the global variable.
my $client->error($message);
Called when libpkgconf comes across a non-fatal error. By default the error is simply displayed as a warning using Carp. The intention of this method is if you want to override that behavior, you will subclass PkgConfig::LibPkgConf::Client and implement your own version of the error method.
error
$client->audit_set_log($filename, $mode);
Opens a file with the C fopen style $mode, and uses it for the audit log. The file is managed entirely by the client class and will be closed when the object falls out of scope. Examples:
fopen
$mode
$client->audit_set_log("audit.log", "a"); # append to existing file $client->audit_set_log("audit2.log", "w"); # new or replace file
