DESCRIPTION

This distribution provides a Perl interface to allow reading and writing of compressed data created with the zlib and bzip2.

IO-Compress supports reading and writing of the following compressed data formats

• bzip2
• RFC 1950
• RFC 1951
• RFC 1952 (i.e. gzip)
• zip

There are a number of companion modules for IO-Compress that extend the suite of compression formats available.

• IO-Compress-Zstd Adds support for zstd (Zstandard).
• IO-Compress-Lzma Adds support for lzma, xz and lzip.
• IO-Compress-Lzf Adds support for lzf.
• IO-Compress-Lzop Adds support for lzop.

Note that the following modules used to be distributed separately, but are now included with the IO-Compress distribution.

Compress-Zlib
IO-Compress-Zlib
IO-Compress-Bzip2
IO-Compress-Base

PREREQUISITES

Before you can build IO-Compress you need to have the following installed on your system:

* Perl 5.006 or better.
* Compress::Raw::Zlib
* Compress::Raw::Bzip2

BUILDING THE MODULE

Assuming you have met all the prerequisites, the module can now be built using this sequence of commands:

FEEDBACK

How to report a problem with IO-Compress.

To help me help you, I need all of the following information:

1. The Versions of everything relevant. This includes:

   a. The complete output from running this

       perl -V
   
   Do not edit the output in any way.
   Note, I want you to run "perl -V" and NOT "perl -v".
   
   If your perl does not understand the "-V" option it is too
   old. This module needs Perl version 5.004 or better.

   b. The version of IO-Compress you have. If you have successfully installed IO-Compress, this one-liner will tell you: perl -MIO::Compress::Gzip -e 'print qq[ver $IO::Compress::Gzip::VERSION\n]' If you are running windows use this perl -MIO::Compress::Gzip -e "print qq[ver $IO::Compress::Gzip::VERSION\n]" If you haven't installed IO-Compress then search IO::Compress::Gzip.pm for a line like this: $VERSION = "2.213" ;

2. If you are having problems building IO-Compress, send me a complete log of what happened. Start by unpacking the IO-Compress module into a fresh directory and keep a log of all the steps, including the setting of configuration environment variables (if applicable).

   [edit config.in or set environment varialbes, if necessary]
   perl Makefile.PL
   make
   make test TEST_VERBOSE=1
