For your convenience and allowed by zlib's license terms:
|
||||
http://www.gzip.org/zlib/zlib_license.html a copy of the zlib source
|
||||
is bundled with SimGear in $(top_srcdir)/src-libs/. You must have
|
||||
zlib installed before you can build SimGear.
|
||||
zlib is prerequisite for compiling SimGear and FlightGear. You can fetch
|
||||
the latest version of zlib from:
|
||||
|
||||
- Most linux distributions have a zlib package. For linux
|
||||
developers, we recommend ysou install your distributions package
|
||||
rather than building from source.
|
||||
http://www.zlib.net
|
||||
|
||||
- Cygwin installs zlib automatically.
|
||||
Most modern unix distributions (and cygwin) come with a version of zlib
|
||||
already installed or available to install as a package.
|
||||
|
||||
- For developers on most other platforms, you will have to build
|
||||
zlib from source and install it yourself. For your convenience a
|
||||
tar ball of the zlib source is included with the simgear source
|
||||
distribution. Untar the zlib source, and follow the included
|
||||
build and installation instructions.
|
||||
|
||||
Once zlib is installed you can return to configuring and building
|
||||
Simgear.
|
||||
|
||||
We now send you to the official zlib README ...

=============================================================================

|
||||
|
||||
zlib 1.1.4 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 jloup@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 1.1.4 are documented in the file ChangeLog.
|
||||
The only changes made since 1.1.3 are bug corrections:
|
||||
|
||||
- ZFREE was repeated on same allocation on some error conditions.
|
||||
This creates a security problem described in
|
||||
http://www.zlib.org/advisory-2002-03-11.txt
|
||||
- Returned incorrect error (Z_MEM_ERROR) on some invalid data
|
||||
- Avoid accesses before window for invalid distances with inflate window
|
||||
less than 32K.
|
||||
- force windowBits > 8 to avoid a bug in the encoder for a window size
|
||||
of 256 bytes. (A complete fix will be available in 1.1.5).
|
||||
|
||||
The beta version 1.1.5beta includes many more changes. A new official
|
||||
version 1.1.5 will be released as soon as extensive testing has been
|
||||
completed on it.
|
||||
|
||||
|
||||
Unsupported third party contributions are provided in directory "contrib".
|
||||
|
||||
A Java implementation of zlib is available in the Java Development Kit
|
||||
http://www.javasoft.com/products/JDK/1.1/docs/api/Package-java.util.zip.html
|
||||
See the zlib home page http://www.zlib.org for details.
|
||||
|
||||
A Perl interface to zlib written by Paul Marquess <pmarquess@bfsec.bt.co.uk>
|
||||
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.westend.com/~kupries/doc/trf/man/man.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 at http://www.winimage.com/zLibDll/unzip.html
|
||||
and also in the contrib/minizip directory of zlib.
|
||||
|
||||
|
||||
Notes for some targets:
|
||||
|
||||
- To build a Windows DLL version, include in a DLL project zlib.def, zlib.rc
|
||||
and all .c files except example.c and minigzip.c; compile with -DZLIB_DLL
|
||||
The zlib DLL support was initially done by Alessandro Iacopetti and is
|
||||
now maintained by Gilles Vollant <info@winimage.com>. Check the zlib DLL
|
||||
home page at http://www.winimage.com/zLibDll
|
||||
|
||||
From Visual Basic, you can call the DLL functions which do not take
|
||||
a structure as argument: compress, uncompress and all gz* functions.
|
||||
See contrib/visual-basic.txt for more information, or get
|
||||
http://www.tcfb.com/dowseware/cmp-z-it.zip
|
||||
|
||||
- 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 Turbo C the small model is supported only with reduced performance to
|
||||
avoid any far allocation; it was tested with -DMAX_WBITS=11 -DMAX_MEM_LEVEL=3
|
||||
|
||||
- For PalmOs, see http://www.cs.uit.no/~perm/PASTA/pilot/software.html
