1 zlib 0.95 is a beta version of a general purpose compression library.
|
|
|
2 This should be the last version before the first official
|
|
|
3 version (1.0), so please test it now. (At least compile and run it with
|
|
|
4 "make test"). This version has no known bugs.
|
|
|
5
|
|
|
6 The data format used by the zlib library is described in the
|
|
|
7 files zlib-3.1.doc, deflate-1.1.doc and gzip-4.1.doc, available
|
|
|
8 in ftp.uu.net:/pub/archiving/zip/doc.
|
|
|
9
|
|
|
10 All functions of the compression library are documented in the file
|
|
|
11 zlib.h. A usage example of the library is given in the file example.c
|
|
|
12 which also tests that the library is working correctly. Another
|
|
|
13 example is given in the file minigzip.c.
|
|
|
14
|
|
|
15 To compile all files and run the test program, just type: make test
|
|
|
16 (For MSDOS, use one of the special makefiles such as Makefile.msc;
|
|
|
17 for VMS, use Make_vms.com or descrip.mms.)
|
|
|
18 To install the zlib library (libz.a) in /usr/local/lib, type: make install
|
|
|
19 To install in a different directory, use for example:
|
|
|
20 make install prefix=$HOME
|
|
|
21 This will install in $HOME/lib instead of /usr/local/lib.

23 The changes made in version 0.95 are documented in the file ChangeLog.
|
|
|
24 The main changes since 0.94 are:
|
|
|
25 - fix MSDOS small and medium model (now easier to adapt to any compiler)
|
|
|
26 - inlined send_bits
|
|
|
27 - fix the final (:-) bug for deflate with flush (output was correct but
|
|
|
28 not completely flushed in rare occasions).
|
|
|
29
|
|
|
30 For MSDOS, the small and medium models have been tested only with Microsoft C.
|
|
|
31 (This should now work for Borland C also, but I don't have a recent Borland
|
|
|
32 compiler to test with.) The small model was tested with Turbo C but only with
|
|
|
33 reduced performance to avoid any far allocation; it was tested with
|
|
|
34 -DMAX_WBITS=11 -DMAX_MEM_LEVEL=3
