SYNOPSIS

In your Makefile.PL:

use ExtUtils::MakeMaker;
use Alien::Base::Wrapper ();

WriteMakefile(
  Alien::Base::Wrapper->new('Alien::libpcre')->mm_args2(
    # MakeMaker args
    NAME => 'My::XS',
    ...
  ),
);

In your Build.PL:

use Module::Build;
use Alien::Base::Wrapper qw( Alien::libpcre !export );

my $builder = Module::Build->new(
  ...
  configure_requires => {
    'Alien::libpcre' => '0',
    ...
  },
  Alien::Base::Wrapper->mb_args,
  ...
);

$build->create_build_script;

In your FFI::Platypus script or module:

use FFI::Platypus;
use Alien::libpcre;

my $ffi = FFI::Platypus->new(
  lib => [ Alien::libpcre->dynamic_libs ],
);

DESCRIPTION

Note that this Alien is for PCRE1, the deprecated older version of the Perl (in)Compatible Regular Expression (PCRE) library. It exists for projects that require the older version of PCRE. Currently the author uses it for source builds of Alien::libnewrelic and NewFangle. If you need the newer currently supported version of PCRE see Alien::PCRE2.

This distribution provides PCRE1 so that it can be used by other Perl distributions that are on CPAN. It does this by first trying to detect an existing install of PCRE1 on your system. If found it will use that. If it cannot be found, the source code will be downloaded from the internet and it will be installed in a private share location for the use of other modules.

CAVEATS

PCRE1 (and PCRE2), is not, as the name might suggest, actually compatible with modern Perl regular expressions.

On Debian based systems (including Ubuntu), the development package for PCRE1 is libpcre3-dev, which is quite confusing, but I am sure there was a good reason for it. If you want to do a system install use that package not the confusingly newer libpcre2-dev.
