+ 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.
