attach_function 'archive_read_new', [], _ptr;DESCRIPTION
This distribution installs libarchive 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 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.
METHODS
cflags
Returns the C compiler flags necessary to build against libarchive.
libs
Returns the library flags necessary to build against libarchive.
dlls
Returns a list of dynamic libraries (usually a list of just one library) that make up libarchive. This can be used for FFI::Raw.
install_type
Returns the install type, one of either system or share.
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.
