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: perl Makefile.PL make make test INSTALLATION ------------ To install IO-Compress, run the command below: make install TROUBLESHOOTING --------------- SUPPORT ------- General feedback/questions/bug reports should be sent to https://github.com/pmqs/IO-Compress/issues (preferred) or https://rt.cpan.org/Public/Dist/Display.html?Name=IO-Compress. 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 = "2.102" ; 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 [edit config.in, if necessary] perl Makefile.PL make make test TEST_VERBOSE=1 Paul Marquess <pmqs@cpan.org>
