- Frequently Asked Questions about zlib
-
-
-If your question is not there, please check the zlib home page
-http://www.zlib.org which may have more recent information.
-The lastest zlib FAQ is at http://www.gzip.org/zlib/zlib_faq.html
-
-
- 1. Is zlib Y2K-compliant?
-
- Yes. zlib doesn't handle dates.
-
- 2. Where can I get a Windows DLL version?
-
- 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
- * http://www.dogma.net/markn/articles/zlibtool/zlibtool.htm
- * contrib/visual-basic.txt in the zlib distribution
-
- 4. compress() 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").
-
- 5. deflate() or inflate() returns Z_BUF_ERROR
-
- 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.)?
-
- 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.
-
- 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.
-
- 8. I found a bug in zlib.
-
- 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"?
-
- If "make test" produces something like
-
- 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.
-
- See the directories contrib/delphi and contrib/delphi2 in the zlib
- distribution.
-
-11. Can zlib handle .zip archives?
-
- See the directory contrib/minizip in the zlib distribution.
-
-12. Can zlib handle .Z files?
-
- 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.
