NAME

Alien::Libarchive - Build and make available libarchive

VERSION

version 0.18

SYNOPSIS

Build.PL

 use Alien::Libarchive;
 use Module::Build;
 
 my $alien = Alien::Libarchive->new;
 my $build = Module::Build->new(
   ...
   extra_compiler_flags => $alien->cflags,
   extra_linker_flags   => $alien->libs,
   ...
 );
 
 $build->create_build_script

Makefile.PL

 use Alien::Libarchive;
 use ExtUtils::MakeMaker;
 
 my $alien = Alien::Libarchive->new;
 WriteMakefile(
   ...
   CFLAGS => Alien::Libarchive->cflags,
   LIBS   => Alien::Libarchive->libs,
 );

FFI

 use Alien::Libarchive;
 use FFI::Sweet qw( ffi_lib );
 
 ffi_lib(Alien::Libarchive->new->libs);

DESCRIPTION

This distribution installs libarchive so that it can be used by other Perl distributions. If already installed for your operating system, and if it can find it, this distribution will use the libarchive 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_LIBARCHIVE to 'share', this distribution will ignore any system libarchive found, and build from source instead. This may be desirable if your operating system comes with a very old version of libarchive and an upgrade path for the system libarchive is not possible.

Requirements

operating system install

The development headers and libraries for libarchive

Debian

On Debian you can install these with this command:

 % sudo apt-get install libarchive-dev
Cygwin

On Cygwin, make sure that this package is installed

 libarchive-devel
FreeBSD

libarchive comes with FreeBSD as of version 5.3.

from source install

A C compiler and any prerequisites for building libarchive.

Debian

On Debian build-essential should be good enough:

 % sudo apt-get install build-essential
Cygwin

On Cygwin, I couldn't get libarchive to build without making a minor tweak to one of the include files. On Cygwin this module will patch libarchive before it attempts to build if it is version 3.1.2.

Strawberry Perl

For MinGW based Perls (including Strawberry), this module will delegate to Alien::Libarchive::MSWin32. The reason for not supporting MinGW directly in this distribution is because it requires CMake at configure time, and I don't want to make that a prereq everywhere.

Probably the easiest way to get this to work is to install CMake binaries from their website,

http://www.cmake.org/cmake/resources/software.html

And then install Alien::CMake.

METHODS

cflags

Returns the C compiler flags necessary to build against libarchive.

libs

Returns the library flags necessary to build against libarchive.

CAVEATS

Debian Linux and FreeBSD (9.0) have been tested the most in development of this distribution.

Patches to improve portability and platform support would be eagerly appreciated.

If you reinstall this distribution, you may need to reinstall any distributions that depend on it as well.
