1.1 misho 1: ZLIB DATA COMPRESSION LIBRARY
2:
3: zlib 1.2.3 is a general purpose data compression library. All the code is
4: thread safe. The data format used by the zlib library is described by RFCs
5: (Request for Comments) 1950 to 1952 in the files
6: http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
7: and rfc1952.txt (gzip format). These documents are also available in other
8: formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html
9:
10: All functions of the compression library are documented in the file zlib.h
11: (volunteer to write man pages welcome, contact zlib@gzip.org). A usage example
12: of the library is given in the file example.c which also tests that the library
13: is working correctly. Another example is given in the file minigzip.c. The
14: compression library itself is composed of all source files except example.c and
15: minigzip.c.
16:
17: To compile all files and run the test program, follow the instructions given at
18: the top of Makefile. In short "make test; make install" should work for most
19: machines. For Unix: "./configure; make test; make install". For MSDOS, use one
20: of the special makefiles such as Makefile.msc. For VMS, use make_vms.com.
21:
22: Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
23: <info@winimage.com> for the Windows DLL version. The zlib home page is
24: http://www.zlib.org or http://www.gzip.org/zlib/ Before reporting a problem,
25: please check this site to verify that you have the latest version of zlib;
26: otherwise get the latest version and check whether the problem still exists or
27: not.
28:
29: PLEASE read the zlib FAQ http://www.gzip.org/zlib/zlib_faq.html before asking
30: for help.
31:
32: Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
33: issue of Dr. Dobb's Journal; a copy of the article is available in
34: http://dogma.net/markn/articles/zlibtool/zlibtool.htm
35:
36: The changes made in version 1.2.3 are documented in the file ChangeLog.
37:
38: Unsupported third party contributions are provided in directory "contrib".
39:
40: A Java implementation of zlib is available in the Java Development Kit
41: http://java.sun.com/j2se/1.4.2/docs/api/java/util/zip/package-summary.html
42: See the zlib home page http://www.zlib.org for details.
43:
44: A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is in the
45: CPAN (Comprehensive Perl Archive Network) sites
46: http://www.cpan.org/modules/by-module/Compress/
47:
48: A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
49: available in Python 1.5 and later versions, see
50: http://www.python.org/doc/lib/module-zlib.html
51:
52: A zlib binding for TCL written by Andreas Kupries <a.kupries@westend.com> is
53: availlable at http://www.oche.de/~akupries/soft/trf/trf_zip.html
54:
55: An experimental package to read and write files in .zip format, written on top
56: of zlib by Gilles Vollant <info@winimage.com>, is available in the
57: contrib/minizip directory of zlib.

60: Notes for some targets:
61:
62: - For Windows DLL versions, please see win32/DLL_FAQ.txt
63:
64: - For 64-bit Irix, deflate.c must be compiled without any optimization. With
65: -O, one libpng test fails. The test works in 32 bit mode (with the -n32
66: compiler flag). The compiler bug has been reported to SGI.
67:
68: - zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
69: when compiled with cc.
70:
71: - On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
72: necessary to get gzprintf working correctly. This is done by configure.
73:
74: - zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
75: other compilers. Use "make test" to check your compiler.
76:
77: - gzdopen is not supported on RISCOS, BEOS and by some Mac compilers.
78:
79: - For PalmOs, see http://palmzlib.sourceforge.net/
80:
81: - When building a shared, i.e. dynamic library on Mac OS X, the library must be
82: installed before testing (do "make install" before "make test"), since the
83: library location is specified in the library.

86: Acknowledgments:

88: The deflate format used by zlib was defined by Phil Katz. The deflate
89: and zlib specifications were written by L. Peter Deutsch. Thanks to all the
90: people who reported problems and suggested various improvements in zlib;
91: they are too numerous to cite here.
