ZLIB DATA COMPRESSION LIBRARY
zlib 1.2.8 is a general purpose data compression
library. All the code is thread safe. The data for-
mat 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 docu-
mented 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 com-
pression 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 <zlib@gzip.
org>, 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 <markn@ieee.org> 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 document-
ed in the file ChangeLog.
Unsupported third party contributions are provided
in directory contrib/ .
zlib is available in Java using the java.util.zip pack-
age, documented at http://java.sun.com/developer/
technicalArticles/Programming/compression/ .
A Perl interface to zlib written by Paul Marquess
<pmqs@cpan.org> is available at CPAN (Compre-
hensive Perl Archive Network) sites, including http://
search.cpan.org/~pmqs/IO-Compress-Zlib/ .
A Python interface to zlib written by A.M.Kuchling
<amk@amk.ca> 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
<info@winimage.com>, 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 Alpha-
Server, the cc option -std1 is necessary to get gz-
printf 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 improve-
ments in zlib; they are too numerous to cite here.
