ZLIB DATA COMPRESSION LIBRARY
zlib 1.2.8 is a general purpose data
compression library. All the code is thread
safe. The data format used by the zlib
library is described by RFCs (Request for
Comments) 1950 to 1952 in the files http://
tools.ietf.org/html/rfc1950 (zlib format),
rfc1951 (deflate format) and rfc1952 (gzip
format).
All functions of the compression library are
documented in the file zlib.h (volunteer to
write man pages welcome, contact zlib@
gzip.org). A usage example of the library is
given in the file test/example.c which also
tests that the library is working correctly.
Another example is given in the file test/
minigzip.c. The compression library itself
is composed of all source files in the root
directory.
To compile all files and run the test program,
follow the instructions given at the top of
Makefile.in. In short "./configure; make test",
and if that goes well, "make install" should
work for most flavors of Unix. For Windows,
use one of the special makefiles in win32/ or
contrib/vstudio/ . For VMS, use make_vms.
com.
Questions about zlib should be sent to
<[email protected]>, or to Gilles Vollant <info@
winimage.com> for the Windows DLL
version. The zlib home page is http://zlib.
net/ . Before reporting a problem, please
check this site to verify that you have the
latest version of zlib; otherwise get the latest
version and check whether the problem still
exists or not.
PLEASE read the zlib FAQ http://zlib.net/
zlib_faq.html before asking for help.
Mark Nelson <[email protected]> wrote an
article about zlib for the Jan. 1997 issue of
Dr. Dobb's Journal; a copy of the article is
available at http://marknelson.us/1997/01/01/
zlib-engine/ .
The changes made in version 1.2.8 are
documented in the file ChangeLog.
Unsupported third party contributions are
provided in directory contrib/ .
zlib is available in Java using the java.util.zip
package, documented at http://java.sun.com/
developer/technicalArticles/Programming/
compression/ .
A Perl interface to zlib written by Paul
Marquess <[email protected]> is available
at CPAN (Comprehensive Perl Archive
Network) sites, including http://search.cpan.
org/~pmqs/IO-Compress-Zlib/ .
A Python interface to zlib written by A.M.
Kuchling <[email protected]> is available in
Python 1.5 and later versions, see http://
docs.python.org/library/zlib.html .
zlib is built into tcl: http://wiki.tcl.tk/4610 .
An experimental package to read and write
files in .zip format, written on top of zlib by
Gilles Vollant <[email protected]>, is
available in the contrib/minizip directory of
zlib.
Notes for some targets:
- For Windows DLL versions, please see
win32/DLL_FAQ.txt
- For 64-bit Irix, deflate.c must be compiled
without any optimization. With
- O, one libpng test fails. The test works in
32 bit mode (with the -n32 compiler flag).
The compiler bug has been reported to
SGI.
- zlib doesn't work with gcc 2.6.3 on a DEC
3000/300LX under OSF/1 2.1 it works
when compiled with cc.
- On Digital Unix 4.0D (formely OSF/1)
on AlphaServer, the cc option -std1 is
necessary to get gzprintf working correctly.
This is done by configure.
- zlib doesn't work on HP-UX 9.05 with some
versions of /bin/cc. It works with other
compilers. Use "make test" to check your
compiler.
- gzdopen is not supported on RISCOS or
BEOS.
- For PalmOs, see http://palmzlib.
sourceforge.net/
Acknowledgments:
The deflate format used by zlib was
defined by Phil Katz. The deflate and zlib
specifications were written by L. Peter
Deutsch. Thanks to all the people who
reported problems and suggested various
improvements in zlib; they are too numerous
to cite here.
