- Frequently Asked Questions about zlib
- If your question is not there, please check the zlib home page
- http://www.cdrom.com/pub/infozip/zlib/ which may have more recent information.
- 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) 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
- 2) I need a Visual Basic interface to zlib
- See http://www.tcfb.com/dowseware/cmp-z-it.zip
- http://web2.airmail.net/markn/articles/zlibtool/zlibtool.htm
- and contrib/visual-basic.txt
- 3) 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").
- 4) deflate or inflate returns Z_BUF_ERROR
- Make sure that before the call avail_in and avail_out are not zero.
- 5) Where is the zlib documentation (man pages, etc...)?
- 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.
- 6) Why don't you use GNU autoconf, libtool, etc...?
- Because we would like to keep zlib as a very small and simple package.
- zlib is rather portable and doesn't need much configuration.
- 7) There is 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 us the corresponding source at zlib@quest.jpl.nasa.gov
- Do not send multi-megabyte data files without prior agreement.
- 8) I get "undefined reference to gzputc"
- 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".
