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".

(smaller lit_bufsize than in gzip 1.2.4) and degraded a little the

compression ratio on some files. This also allows inlining _tr_tally for

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.
|
||||
|
||||
- For shared memory multiprocessors, the decompression code assumes that
|
||||
writes to pointers are atomic. Also the functions zalloc and zfree passed
|
||||
to deflateInit must be multi-threaded in this case.
|
||||
|

- 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
