Gzip 1.0.3 for Linux, GNU's archiver compatible with compress, pack, and its own deflation method. Needed for extrating members from GCC 2.3.3, and new SLS releases.

Full Description of File


This is a complete Gzip package for Linux,
ready to install. Before installing, move
/usr/bin/uncompress to uncompress.old and
move /usr/bin/zcat to zcat.old. Then go
to the file system root directory and do
a "tar xvf gzip203.tar" to install.

This is a complete Gzip package for Linux,
ready to install. Before installing, move

This is the file README for the gzip distribution, version 1.0.3.

gzip (GNU zip) is a compression utility designed to be a replacement
for 'compress'. Its main advantages over compress are much better
compression and freedom from patented algorithms. The GNU Project
uses it as the standard compression program for its system.

gzip currently uses by default the LZ77 algorithm used in zip 1.9 (the
portable pkzip compatible archiver). The gzip format was however
designed to accommodate several compression algorithms.

gunzip can currently decompress files created by gzip, zip (with
restrictions), compress or pack. The detection of the input format is
automatic. When using the first two formats, gunzip checks a 32 bit
CRC. For pack, gunzip checks the uncompressed length. The 'compress'
format was not designed to allow consistency checks. However gunzip
is sometimes able to detect a bad .Z file because there is some
redundancy in the .Z compression format. If you get an error
when uncompressing a .Z file, do not assume that the .Z file is
correct simply because the standard uncompress does not complain.
This generally means that the standard uncompress does not check its
input, and happily generates garbage output.

gzip produces files with a .z extension. This was chosen to mimic the
'compress' .Z extension. Using exactly the same extension would have
caused too much confusion. Using a completely different extension
would have forced changes in other programs such as GNU tar (which has
a -z option). The .z extension is already used by the 'pack'
Huffman encoder, but gunzip is able to decompress packed files.

Several planned features are not yet supported (see the file TODO).
See the file INSTALL for installation instructions. See the file NEWS
for a summary of changes since 0.5.

WARNINGS about broken optimizers:

- on the NeXT, "cc -finline-functions" is broken. gzip produces
valid .z files but they are much too large because the string
matching code misses most matches. Use "cc -O" instead.

- on the Mips R4000, gcc -O (version 2.3.1) generates bad code, use cc
or just gcc -g instead.

- on SparcStation with SunOS 4.1.1 and the SC1.0 compiler, the optimizer
works up to -O3 but -O4 does not work.

- MSC 5.1 with -Ox and -DDYN_ALLOC generates bad code in inflate.c.
The default is static allocation (no DYN_ALLOC) and -Ox works.
But -Ox does not work on util.c, so you must use -Oait -Gs.

For all machines, Use "make check" to check that gzip was compiled correctly.

Please send all comments and bug reports by electronic mail to:
Jean-loup Gailly

or, if this fails, to [email protected]
Bug reports should ideally include:

* The complete output of "gzip -V" (or the contents of revision.h
if you can't get gzip to compile)
* The hardware and operating system
* The compiler used to compile
* A description of the bug behavior
* The input to gzip, that triggered the bug

The package crypt++.el is highly recommended to manipulate gzip'ed
file from emacs. It recognizes automatically encrypted and compressed
files when they are first visited or written. It is available via
anonymous ftp to roebling.poly.edu [128.238.5.31] in /pub/crypt++.el.
The same directory contains also patches to dired, ange-ftp, info and
tar.

gzip is free software, you can redistribute it and/or modify it under
the terms of the GNU General Public License, a copy of which is
provided under the name COPYING. The latest version of the gzip
sources can always be found in prep.ai.mit.edu:/pub/gnu/gzip-*.tar*
or any of the prep mirror sites. An MSDOS lha self-extracting exe is in
hal.gnu.ai.mit.edu:/tmp/gzip*.exe.

Many thanks to those who provided me with bug reports and feedback.
