ZLIB DATA COMPRESSION LIBRARY





zlib 1.2.1 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://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)


and rfc1952.txt (gzip format). These documents are also available in other


formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html





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 example.c which also tests that the library


is working correctly. Another example is given in the file minigzip.c. The


compression library itself is composed of all source files except example.c and


minigzip.c.





To compile all files and run the test program, follow the instructions given at


the top of Makefile. In short "make test; make install" should work for most


machines. For Unix: "./configure; make test; make install" For MSDOS, use one


of the special makefiles such as Makefile.msc. For VMS, use Make_vms.com or


descrip.mms.





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://www.zlib.org or http://www.gzip.org/zlib/ 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://www.gzip.org/zlib/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 in


http://dogma.net/markn/articles/zlibtool/zlibtool.htm





The changes made in version 1.2.1 are documented in the file ChangeLog.





Unsupported third party contributions are provided in directory "contrib".





A Java implementation of zlib is available in the Java Development Kit


http://java.sun.com/j2se/1.4.2/docs/api/java/util/zip/package-summary.html


See the zlib home page http://www.zlib.org for details.





A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is in the


CPAN (Comprehensive Perl Archive Network) sites


http://www.cpan.org/modules/by-module/Compress/





A Python interface to zlib written by A.M. Kuchling <amk@magnet.com> is


available in Python 1.5 and later versions, see


http://www.python.org/doc/lib/module-zlib.html





A zlib binding for TCL written by Andreas Kupries <a.kupries@westend.com> is


availlable at http://www.oche.de/~akupries/soft/trf/trf_zip.html





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 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, BEOS and by some Mac compilers.





- For PalmOs, see http://palmzlib.sourceforge.net/





- When building a shared, i.e. dynamic library on Mac OS X, the library must be


  installed before testing (do "make install" before "make test"), since the


  library location is specified in the library.








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.
