Changes in 1.1.4 (11 March 2002)
|
||||
- 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).
|
||||
|
||||
Changes in 1.1.3 (9 July 1998)
|
||||
- fix "an inflate input buffer bug that shows up on rare but persistent
|
||||
occasions" (Mark)

The lastest zlib FAQ is at http://www.gzip.org/zlib/zlib_faq.html
|
||||
|
||||
|
||||
1) I need a Windows DLL
|
||||
2) I need a Visual Basic interface to zlib
|
||||
3) compress() returns Z_BUF_ERROR
|
||||
4) deflate or inflate returns Z_BUF_ERROR
|
||||
5) Where is the zlib documentation (man pages, etc...)?
|
||||
6) Why don't you use GNU autoconf, libtool, etc...?
|
||||
7) There is a bug in zlib.
|
||||
8) I get "undefined reference to gzputc"
|
||||
1. Is zlib Y2K-compliant?
|
||||
|
||||
Yes. zlib doesn't handle dates.
|
||||
|
||||
2. Where can I get a Windows DLL version?
|
||||
|
||||
1) I need a Windows DLL
|
||||
The zlib sources can be compiled without change to produce a DLL. If you
|
||||
want a precompiled DLL, see http://www.winimage.com/zLibDll/ . Questions
|
||||
about the zlib DLL should be sent to Gilles Vollant (info@winimage.com).

3. Where can I get a Visual Basic interface to zlib?
|
||||

See

||||
* http://www.winimage.com/zLibDll/cmp-z-it.zip

|
||||
2) I need a Visual Basic interface to zlib
|
||||
4. compress() returns Z_BUF_ERROR
|
||||
|
||||
See http://www.tcfb.com/dowseware/cmp-z-it.zip
|
||||
http://web2.airmail.net/markn/articles/zlibtool/zlibtool.htm
|
||||
and contrib/visual-basic.txt
|
||||
Make sure that before the call of compress, the length of the compressed
|
||||
buffer is equal to the total size of the compressed buffer and not
|
||||
zero. For Visual Basic, check that this parameter is passed by reference
|
||||
("as any"), not by value ("as long").
|
||||
|
||||
3) compress() returns Z_BUF_ERROR
|
||||
5. deflate() or inflate() returns Z_BUF_ERROR
|
||||
|
||||
Make sure that before the call of compress, the length of the
|
||||
compressed buffer is equal to the total size of the compressed buffer
|
||||
and not zero. For Visual Basic, check that this parameter is passed
|
||||
by reference ("as any"), not by value ("as long").
|
||||
Before making the call, make sure that avail_in and avail_out are not
|
||||
zero. When setting the parameter flush equal to Z_FINISH, also make sure
|
||||
that avail_out is big enough to allow processing all pending input.
|
||||
|
||||
6. Where's the zlib documentation (man pages, etc.)?
|
||||
|
||||
4) deflate or inflate returns Z_BUF_ERROR
|
||||
It's in zlib.h for the moment, and Francis S. Lin has converted it to a
|
||||
web page zlib.html. Volunteers to transform this to Unix-style man pages,
|
||||
please contact Jean-loup Gailly (jloup@gzip.org). Examples of zlib usage
|
||||
are in the files example.c and minigzip.c.
|
||||
|
||||
Make sure that before the call avail_in and avail_out are not zero.
|
||||
7. Why don't you use GNU autoconf or libtool or ...?
|
||||
|
||||
Because we would like to keep zlib as a very small and simple
|
||||
package. zlib is rather portable and doesn't need much configuration.
|
||||
|
||||
5) Where is the zlib documentation (man pages, etc...)?
|
||||
8. I found a bug in zlib.
|
||||
|
||||
It's in zlib.h for the moment. Volunteers to transform this
|
||||
to man pages, please contact jloup@gzip.org. Examples of zlib usage
|
||||
are in the files example.c and minigzip.c.
|
||||
Most of the time, such problems are due to an incorrect usage of
|
||||
zlib. Please try to reproduce the problem with a small program and send
|
||||
the corresponding source to us at zlib@gzip.org . Do not send
|
||||
multi-megabyte data files without prior agreement.
|
||||
|
||||
9. Why do I get "undefined reference to gzputc"?
|
||||
|
||||
6) Why don't you use GNU autoconf, libtool, etc...?
|
||||
If "make test" produces something like
|
||||
|
||||
Because we would like to keep zlib as a very small and simple package.
|
||||
zlib is rather portable and doesn't need much configuration.
|
||||
example.o(.text+0x154): undefined reference to `gzputc'
|
||||
|
||||
check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
|
||||
/usr/X11R6/lib. Remove any old versions, then do "make install".
|
||||
|
||||
10. I need a Delphi interface to zlib.
|
||||
|
||||
7) There is a bug in zlib.
|
||||
See the directories contrib/delphi and contrib/delphi2 in the zlib
|
||||
distribution.
|
||||
|
||||
Most of the time, such problems are due to an incorrect usage
|
||||
of zlib. Please try to reproduce the problem with a small
|
||||
program and send us the corresponding source at zlib@quest.jpl.nasa.gov
|
||||
Do not send multi-megabyte data files without prior agreement.
|
||||
11. Can zlib handle .zip archives?
|
||||
|
||||
See the directory contrib/minizip in the zlib distribution.
|
||||
|
||||
8) I get "undefined reference to gzputc"
|
||||
12. Can zlib handle .Z files?
|
||||
|
||||
If "make test" produces something like
|
||||
example.o(.text+0x174):
|
||||
check that you don't have old files libz.* in /usr/lib, /usr/local/lib
|
||||
or /usr/X11R6/lib. Remove old versions then do "make install".
|
||||
No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt
|
||||
the code of uncompress on your own.
|
||||
|
||||
13. How can I make a Unix shared library?
|
||||
|
||||
make clean
|
||||
./configure -s
|
||||
make
|
||||
|
||||
14. Why does "make test" fail on Mac OS X?
|
||||
|
||||
Mac OS X already includes zlib as a shared library, and so -lz links the
|
||||
shared library instead of the one that the "make" compiled. For zlib
|
||||
1.1.3, the two are incompatible due to different compile-time
|
||||
options. Simply change the -lz in the Makefile to libz.a, and it will use
|
||||
the compiled library instead of the shared one and the "make test" will
|
||||
succeed.
|
||||
|
||||
15. I have a question about OttoPDF
|
||||
|
||||
We are not the authors of OttoPDF. The real author is on the OttoPDF web
|
||||
site Joel Hainley jhainley@myndkryme.com.
