    Alien::bz2 - Build and make available bz2

VERSION

    version 0.17

SYNOPSIS

    Build.PL

     use Alien::bz2;
     use Module::Build;
     
     my $alien = Alien::bz2-&gt;new;
     my $build = Module::Build-&gt;new(
       ...
       extra_compiler_flags =&gt; [$alien-&gt;cflags],
       extra_linker_flags   =&gt; [$alien-&gt;libs],
       ...
     );
     
     $build-&gt;create_build_script;

    Makefile.PL

     use Alien::bz2;
     use ExtUtils::MakeMaker;
     
     my $alien = Alien::bz2;
     WriteMakefile(
       ...
       CCFLAGS =&gt; scalar $alien-&gt;cflags,
       LIBS   =&gt; [$alien-&gt;libs],
     );

    FFI::Platypus

     use Alien::bz2;
     use FFI::Platypus;
     
     my $ffi = FFI::Platypus-&gt;new(lib =&gt; [Alien::bz2-&gt;new-&gt;dlls]);
     $ffi-&gt;attach( BZ2_bzlibVersion =&gt; [] =&gt; 'string' );

DESCRIPTION

    If you just want to compress or decompress bzip2 data in Perl you
    probably want one of Compress::Bzip2, Compress::Raw::Bzip2 or
    IO::Compress::Bzip2.

    This distribution installs bz2 so that it can be used by other Perl
    distributions. If already installed for your operating system, and it
    can be found, this distribution will use the bz2 that comes with your
    operating system, otherwise it will download it from the Internet,
    build and install it.

    If you set the environment variable ALIEN_BZ2 to 'share', this
    distribution will ignore any system bz2 found, and build from source
    instead. This may be desirable if your operating system comes with a
    very old version of bz2 and an upgrade path for the system bz2 is not
    possible.

    This distribution also honors the ALIEN_FORCE environment variable used
    by Alien::Base. Setting ALIEN_FORCE has the same effect as setting
    ALIEN_BZ2 to 'share'.

METHODS

 cflags

    Returns the C compiler flags necessary to build against bz2.

    Returns flags as a list in list context and combined into a string in
    scalar context.

 libs

    Returns the library flags necessary to build against bz2.

    Returns flags as a list in list context and combined into a string in
    scalar context.

 dlls

    Returns a list of dynamic libraries (usually a list of just one
    library) that make up bz2. This can be used for FFI::Raw.

    Returns just the first dynamic library found in scalar context.

 version

    Returns the version of bz2.

 install_type

    Returns the install type, one of either system or share.
