Compress::Raw::Zlib::FAQ -- Frequently Asked Questions about Compress::Raw::Zlib
Common questions answered.
This module is not compatible with Unix compress.
compress
If you have the uncompress program available, you can use this to read compressed files
uncompress
open F, "uncompress -c $filename |"; while (<F>) { ...
Alternatively, if you have the gunzip program available, you can use this to read compressed files
gunzip
open F, "gunzip -c $filename |"; while (<F>) { ...
and this to write compress files, if you have the compress program available
open F, "| compress -c $filename "; print F "data"; ... close F ;
See previous FAQ item.
If the Archive::Tar module is installed and either the uncompress or gunzip programs are available, you can use one of these workarounds to read .tar.Z files.
Archive::Tar
.tar.Z
Firstly with uncompress
use strict; use warnings; use Archive::Tar; open F, "uncompress -c $filename |"; my $tar = Archive::Tar->new(*F); ...
and this with gunzip
use strict; use warnings; use Archive::Tar; open F, "gunzip -c $filename |"; my $tar = Archive::Tar->new(*F); ...
Similarly, if the compress program is available, you can use this to write a .tar.Z file
use strict; use warnings; use Archive::Tar; use IO::File; my $fh = new IO::File "| compress -c >$filename"; my $tar = Archive::Tar->new(); ... $tar->write($fh); $fh->close ;
This module does not support reading/writing zip files.
Support for reading/writing zip files is included with the IO::Compress::Zip and IO::Uncompress::Unzip modules.
IO::Compress::Zip
IO::Uncompress::Unzip
The primary focus of the IO::Compress::Zip and IO::Uncompress::Unzip modules is to provide an IO::File compatible streaming read/write interface to zip files/buffers. They are not fully flegged archivers. If you are looking for an archiver check out the Archive::Zip module. You can find it on CPAN at
IO::File

By default Compress::Raw::Zlib will build with a private copy of version 1.2.3 of the zlib library. (See the README file for details of how to override this behaviour)
Compress::Raw::Zlib
If you decide to use a different version of the zlib library, you need to be aware of the following issues
First off, you must have zlib 1.0.5 or better.
You need to have zlib 1.2.1 or better if you want to use the -Merge option with IO::Compress::Gzip, IO::Compress::Deflate and IO::Compress::RawDeflate.
