|

zlib 1.2.11 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).
|
||||
|
||||
1. Introduction
|
||||
---------------
|
||||
Tcl provides a powerful platform for creating integration applications that
|
||||
tie together diverse applications, protocols, devices, and frameworks.
|
||||
When paired with the Tk toolkit, Tcl provides the fastest and most powerful
|
||||
way to create GUI applications that run on PCs, Unix, and Mac OS X.
|
||||
Tcl can also be used for a variety of web-related tasks and for creating
|
||||
powerful command languages for applications.
|
||||
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.
|
||||
|
||||
Tcl is maintained, enhanced, and distributed freely by the Tcl community.
|
||||
Source code development and tracking of bug reports and feature requests
|
||||
takes place at:
|
||||
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.
|
||||
|
||||
http://core.tcl-lang.org/
|
||||
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.
|
||||
|
||||
Tcl/Tk release and mailing list services are hosted by SourceForge:
|
||||
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/ .
|
||||
|
||||
with the Tcl Developer Xchange hosted at:
|
||||
The changes made in version 1.2.11 are documented in the file ChangeLog.
|
||||
|
||||
http://www.tcl-lang.org/
|
||||
Unsupported third party contributions are provided in directory contrib/ .
|
||||
|
||||
Tcl is a freely available open source package. You can do virtually
|
||||
anything you like with it, such as modifying it, redistributing it,
|
||||
and selling it either in whole or in part. See the file
|
||||
"license.terms" for complete information.
|
||||
zlib is available in Java using the java.util.zip package, documented at
|
||||
http://java.sun.com/developer/technicalArticles/Programming/compression/ .
|
||||
|
||||
2. Documentation
|
||||
----------------
|
||||
A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available
|
||||
at CPAN (Comprehensive Perl Archive Network) sites, including
|
||||
http://search.cpan.org/~pmqs/IO-Compress-Zlib/ .

|
||||
http://www.tcl-lang.org/software/tcltk/8.6.html
|
||||
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 .
|
||||
|
||||
Detailed release notes can be found at the file distributions page
|
||||

||||
zlib is built into tcl: http://wiki.tcl.tk/4610 .
|
||||
|
||||
Information about Tcl itself can be found at
|
||||
http://www.tcl-lang.org/about/
|
||||
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.
|
||||
|
||||
There have been many Tcl books on the market. Many are mentioned in the Wiki:

|
||||
Notes for some targets:
|
||||
|
||||
2a. Unix Documentation
|
||||
----------------------
|
||||
- For Windows DLL versions, please see win32/DLL_FAQ.txt
|
||||
|
||||
The "doc" subdirectory in this release contains a complete set of
|
||||
reference manual entries for Tcl. Files with extension ".1" are for
|
||||
programs (for example, tclsh.1); files with extension ".3" are for C
|
||||
library procedures; and files with extension ".n" describe Tcl
|
||||
commands. The file "doc/Tcl.n" gives a quick summary of the Tcl
|
||||
language syntax. To print any of the man pages on Unix, cd to the
|
||||
"doc" directory and invoke your favorite variant of troff using the
|
||||
normal -man macros, for example
|
||||
- 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.
|
||||
|
||||
ditroff -man Tcl.n
|
||||
- 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.
|
||||
|
||||
to print Tcl.n. If Tcl has been installed correctly and your "man" program
|
||||
supports it, you should be able to access the Tcl manual entries using the
|
||||
normal "man" mechanisms, such as
|
||||
- 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.
|
||||
|
||||
man Tcl
|
||||
- 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.
|
||||
|
||||
2b. Windows Documentation
|
||||
-------------------------
|
||||
- gzdopen is not supported on RISCOS or BEOS.
|
||||
|
||||
The "doc" subdirectory in this release contains a complete set of Windows
|
||||
help files for Tcl. Once you install this Tcl release, a shortcut to the
|
||||
Windows help Tcl documentation will appear in the "Start" menu:
|
||||

3. Compiling and installing Tcl
|
||||
-------------------------------
|
||||
Acknowledgments:
|
||||
|
||||
There are brief notes in the unix/README, win/README, and macosx/README about
|
||||
compiling on these different platforms. There is additional information
|
||||
about building Tcl from sources at
|
||||
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.

5. Tcl newsgroup
|
||||
----------------
|
||||
1. The origin of this software must not be misrepresented; you must not
|
||||
claim that you wrote the original software. If you use this software
|
||||
in a product, an acknowledgment in the product documentation would be
|
||||
appreciated but is not required.
|
||||
2. Altered source versions must be plainly marked as such, and must not be
|
||||
misrepresented as being the original software.
|
||||
3. This notice may not be removed or altered from any source distribution.
|
||||
|
||||
There is a USENET news group, "comp.lang.tcl", intended for the exchange of
|
||||
information about Tcl, Tk, and related applications. The newsgroup is a
|
||||
great place to ask general information questions. For bug reports, please
|
||||
see the "Support and bug fixes" section below.

||||
6. Tcl'ers Wiki
|
||||
---------------
|
||||
If you use the zlib library in a product, we would appreciate *not* receiving
|
||||
lengthy legal documents to sign. The sources are provided for free but without
|
||||
warranty of any kind. The library has been entirely written by Jean-loup
|
||||
Gailly and Mark Adler; it does not include third-party code.
|
||||
|
||||
A Wiki-based open community site covering all aspects of Tcl/Tk is at:
|
||||
|
||||
http://wiki.tcl-lang.org/
|
||||
|
||||
It is dedicated to the Tcl programming language and its extensions. A
|
||||
wealth of useful information can be found there. It contains code
|
||||
snippets, references to papers, books, and FAQs, as well as pointers to
|
||||
development tools, extensions, and applications. You can also recommend
|
||||
additional URLs by editing the wiki yourself.
|
||||
|
||||
7. Mailing lists
|
||||
----------------
|
||||
|
||||
Several mailing lists are hosted at SourceForge to discuss development or
|
||||
use issues (like Macintosh and Windows topics). For more information and
|
||||
to subscribe, visit:
|
||||
|
||||
http://sourceforge.net/projects/tcl/
|
||||
|
||||
and go to the Mailing Lists page.
|
||||
|
||||
8. Support and Training
|
||||
------------------------
|
||||
|
||||
We are very interested in receiving bug reports, patches, and suggestions
|
||||
for improvements. We prefer that you send this information to us as
|
||||
tickets entered into our tracker at:
|
||||
|
||||
http://core.tcl-lang.org/tcl/reportlist
|
||||
|
||||
We will log and follow-up on each bug, although we cannot promise a
|
||||
specific turn-around time. Enhancements may take longer and may not happen
|
||||
at all unless there is widespread support for them (we're trying to
|
||||
slow the rate at which Tcl/Tk turns into a kitchen sink). It's very
|
||||
difficult to make incompatible changes to Tcl/Tk at this point, due to
|
||||
the size of the installed base.
|
||||
|
||||
The Tcl community is too large for us to provide much individual support
|
||||
for users. If you need help we suggest that you post questions to
|
||||
comp.lang.tcl. We read the newsgroup and will attempt to answer esoteric
|
||||
questions for which no one else is likely to know the answer. In addition,
|
||||
see the following Web site for links to other organizations that offer
|
||||
Tcl/Tk training:
|
||||
|
||||
http://wiki.tcl-lang.org/training
|
||||
|
||||
9. Tracking Development
|
||||
-----------------------
|
||||
|
||||
Tcl is developed in public. To keep an eye on how Tcl is changing, see
|
||||
http://core.tcl-lang.org/
|
||||
|
||||
10. Thank You
|
||||
-------------
|
||||
|
||||
We'd like to express our thanks to the Tcl community for all the
|
||||
helpful suggestions, bug reports, and patches we have received.
|
||||
Tcl/Tk has improved vastly and will continue to do so with your help.
|
||||
If you redistribute modified sources, we would appreciate that you include in
|
||||
the file ChangeLog history information documenting your changes. Please read
|
||||
the FAQ for more information on the distribution of modified source versions.

ZLIB DATA COMPRESSION LIBRARY
|
||||
|
||||
zlib 1.2.11 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 <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 1.2.11 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 <pmqs@cpan.org> 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 <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 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.

Installing ZLIB1.DLL
|
||||
====================
|
||||
Copy ZLIB1.DLL to the SYSTEM or the SYSTEM32 directory.
|
||||
|
||||
If you want to install the 32-bit dll on a 64-bit
|
||||
machine, use the SysWOW64 directory instead.
|
||||
|
||||
|
||||
Using ZLIB1.DLL with Microsoft Visual C++
|
||||
=========================================
|
||||
1. Install the supplied header files "zlib.h" and "zconf.h"
|
||||
into a directory found in the INCLUDE path list.
|
||||
|
||||
2. Install the supplied library file "zdll.lib" into a
|
||||
directory found in the LIB path list.
|
||||
|
||||
3. Add "zdll.lib" to your project.
|
||||
|
||||
|
||||
Using ZLIB1.DLL with gcc/MinGW
|
||||
==============================
|
||||
1. Install the supplied header files "zlib.h" and "zconf.h"
|
||||
into the INCLUDE directory.
|
||||
|
||||
2. (32-bit): Copy the supplied library file "zdll.lib" to "libzdll.a":
|
||||
cp lib/zdll.lib lib/libzdll.a
|
||||
|
||||
OR
|
||||
|
||||
2'. (64-bit): Copy the supplied library file "libz.dll.a" to "libzdll.a":
|
||||
cp lib/libz.dll.a lib/libzdll.a
|
||||
|
||||
OR
|
||||
|
||||
2'' Build the import library from the supplied "zlib.def":
|
||||
dlltool -D zlib1.dll -d lib/zlib.def -l lib/libzdll.a
|
||||
|
||||
3. Install "libzdll.a" into the LIB directory.
|
||||
|
||||
4. Add "libzdll.a" to your project, or use the -lzdll option.
|
||||
|
||||
|
||||
Using ZLIB1.DLL with gcc/Cygwin
|
||||
===============================
|
||||
ZLIB1.DLL is not designed to work with Cygwin. The Cygwin
|
||||
system has its own DLL build of zlib, named CYGZ.DLL.
|
||||
|
||||
|
||||
Using ZLIB1.DLL with Borland C++
|
||||
================================
|
||||
1. Install the supplied header files "zlib.h" and "zconf.h"
|
||||
into a directory found in the INCLUDE path list.
|
||||
|
||||
2. Build the import library using the IMPLIB tool:
|
||||
implib -a -c -f lib\zdllbor.lib zlib1.dll
|
||||
|
||||
OR
|
||||
|
||||
2' Convert the supplied library file "zdll.lib" to OMF format,
|
||||
using the COFF2OMF tool:
|
||||
coff2omf lib\zdll.lib lib\zdllbor.lib
|
||||
|
||||
3. Install "zdllbor.lib" into a directory found in the LIB path
|
||||
list.
|
||||
|
||||
4. Add "zdllbor.lib" to your project.
|
||||
|
||||
Notes:
|
||||
- The modules that are linked with "zdllbor.lib" must be compiled
|
||||
using a 4-byte alignment (option -a):
|
||||
bcc32 -a -c myprog.c
|
||||
bcc32 myprog.obj zdllbor.lib
|
||||
- If you wish, you may use "zlib1.lib" instead of "zdllbor.lib".
|
||||
|
||||
|
||||
Rebuilding ZLIB1.DLL
|
||||
====================
|
||||
Depending on your build environment, use the appropriate
|
||||
makefile from the win32/ directory, found in the zlib source
|
||||
distribution.
|
||||
|
||||
Your custom build has to comply with the requirements stated
|
||||
in DLL_FAQ.txt, including (but not limited to) the following:
|
||||
- It must be built from an unaltered zlib source distribution.
|
||||
- It must be linked to MSVCRT.DLL.
|
||||
- The macros that compile out certain portions of the zlib
|
||||
code (such as NO_GZCOMPRESS, NO_GZIP) must not be enabled.
|
||||
- The ZLIB_WINAPI macro must not be enabled.
|
||||
|
||||
Furthermore, it has to run successfully with the test suite
|
||||
found in this package.
|
||||
|
||||
It is recommended, however, to use the supplied ZLIB1.DLL,
|
||||
instead of rebuilding it yourself. You should rebuild it
|
||||
only if you have a special reason.

The wrapper includes support for inflating/deflating memory buffers,
|

.Net streaming wrappers for the gz streams part of zlib, and wrappers
|
||||
for the checksum parts of zlib. See DotZLib/UnitTests.cs for examples.

Unit tests:
|
||||
-----------
|
||||
The file DotZLib/UnitTests.cs contains unit tests for use with NUnit 2.1 or higher.
|
||||
To include unit tests in the build, define nunit before building.
|
||||
|
||||
|
||||
Build instructions:
|
||||
-------------------
|
||||
|
||||
1. Using Visual Studio.Net 2003:
|
||||
Open DotZLib.sln in VS.Net and build from there. Output file (DotZLib.dll)
|
||||
will be found ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on
|
||||
you are building the release or debug version of the library. Check
|
||||
DotZLib/UnitTests.cs for instructions on how to include unit tests in the
|
||||
build.
|
||||
|
||||
2. Using NAnt:
|
||||
Open a command prompt with access to the build environment and run nant
|
||||
in the same directory as the DotZLib.build file.
|
||||
You can define 2 properties on the nant command-line to control the build:
|
||||
debug={true|false} to toggle between release/debug builds (default=true).
|
||||
nunit={true|false} to include or esclude unit tests (default=true).
|
||||
Also the target clean will remove binaries.
|
||||
Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release
|
||||
or ./DotZLib/bin/debug, depending on whether you are building the release
|
||||
or debug version of the library.
|
||||
|
||||
Examples:
|
||||
nant -D:debug=false -D:nunit=false
|
||||
will build a release mode version of the library without unit tests.
|
||||
nant
|
||||
will build a debug version of the library with unit tests
|
||||
nant clean
|
||||
will remove all previously built files.
