- zlib 0.95 is a beta version of a general purpose compression library.
- This should be the last version before the first official
- version (1.0), so please test it now. (At least compile and run it with
- "make test"). This version has no known bugs.
- The data format used by the zlib library is described in the
- files zlib-3.1.doc, deflate-1.1.doc and gzip-4.1.doc, available
- in ftp.uu.net:/pub/archiving/zip/doc.
- All functions of the compression library are documented in the file
- zlib.h. A usage example of the library is given in the file example.c
- which also tests that the library is working correctly. Another
- example is given in the file minigzip.c.
- To compile all files and run the test program, just type: make test
- (For MSDOS, use one of the special makefiles such as Makefile.msc;
- for VMS, use Make_vms.com or descrip.mms.)
- To install the zlib library (libz.a) in /usr/local/lib, type: make install
- To install in a different directory, use for example:
- make install prefix=$HOME
- This will install in $HOME/lib instead of /usr/local/lib.
- The changes made in version 0.95 are documented in the file ChangeLog.
- The main changes since 0.94 are:
- - fix MSDOS small and medium model (now easier to adapt to any compiler)
- - inlined send_bits
- - fix the final (:-) bug for deflate with flush (output was correct but
- not completely flushed in rare occasions).
- For MSDOS, the small and medium models have been tested only with Microsoft C.
- (This should now work for Borland C also, but I don't have a recent Borland
- compiler to test with.) The small model was tested with Turbo C but only with
- reduced performance to avoid any far allocation; it was tested with
- -DMAX_WBITS=11 -DMAX_MEM_LEVEL=3
