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.
