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.
For partial compatibility with Alien::Base, this distribution will also
honor the ALIEN_FORCE environment variable. Setting ALIEN_BASE to a
true value is the same as setting ALIEN_LIBARCHIVE to 'share'.
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.
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.
Returns the C compiler flags necessary to build against libarchive.
Returns flags as a list in list context and combined into a string in scalar context.
Returns the library flags necessary to build against libarchive.
Returns flags as a list in list context and combined into a string in scalar context.
Returns a list of dynamic libraries (usually a list of just one library) that make up libarchive. This can be used for FFI::Raw.
Returns just the first dynamic library found in scalar context.
Returns the libarchive version.
Returns the install type, one of either system or share.
Returns a path that contains the libarchive.pc file which can be used by pkg-config for linking against libarchive.
Returns the name by which pkg-config knows libarchive (should always be libarchive).
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.
