A Bit Of History
You'll find gzip using the same compression
that was written by Jean-loup Gailly
for the Info-Zip Group
whose Zip
program is compatible with msdos PKZIP program from
PK Ware. Then, in collaboration
with Mark Adler
he wrote the zlib
compression library which was later standardized in the
zlib RFCs, namely
RFC 1950
zlib 3.3,
RFC 1951
deflate 1.3 and
RFC 1952
gzip 4.3. The free algorithm can be found in lots of places
today including PPP packet compression and PNG picture compression.
Installation
The installation is from the source .tar.gz tarball does follow
the simple gnu style: type ''configure && make install''
in the unpacked directory. This will actually perform the usual
sequence of ''configure && make && make install''. The
use of ''make rpm'' will make rpms based on your system
setup, and using a decent mingw32 compiler (e.g. the crossgcc
from libsdl.org/Xmingw32)
will allow you to create windows dlls using a gnu development
environment. MSVC and Borland support (Make-)files should be
easy to be derived from the Makefile.am
Contact
The library was developed by
Guido Draheim based on the library
zip08x
by Tomi Ollila (many thanks
for his support of the zziplib project). He has provided
a good deal of testing rounds and very helpful comments.
It may be assumed that this library supersedes
zip08x, and in April 2002, he
has even given up copyright restrictions coming from zip08x
and changed the zip08x
readme to point to zziplib.
Anyone who wants to contribute in accessing zip-archives
with the zlib-library is hereby kindly invited to send us
comments and sourcecode.
Links
The zziplib library must be
linked with the free zlib
[1]
[2]
[3] package originally developed
by the Info-Zip Group
and now maintained at the GZip Group.
Be also aware of other zzip like projects, e.g.
zipios++ that
mangles zip access into C++ iostream facilities.
