XZ Utils for Windows
|
|
====================
|
|
|
|
Introduction
|
|
------------
|
|
|
|
This package includes command line tools (xz.exe and a few
|
|
others) and the liblzma compression library from XZ Utils.
|
|
You can find the latest version and full source code from
|
|
<https://tukaani.org/xz/>.
|
|
|
|
The parts of the XZ Utils source code, that are relevant to this
|
|
binary package, are under the BSD Zero Clause License (0BSD).
|
|
XZ Utils have been built using GCC and MinGW-w64 and linked
|
|
statically against the MinGW-w64 runtime libraries. See
|
|
COPYING.MinGW-w64-runtime.txt for copyright and license
|
|
information that applies to the MinGW-w64 runtime.
|
|
|
|
IMPORTANT: You must include COPYING.MinGW-w64-runtime.txt
|
|
when distributing these XZ Utils binaries to meet
|
|
the license terms of the MinGW-w64 runtime!
|
|
|
|
(The file COPYING mentions GNU getopt_long. It's *not* used when
|
|
XZ Utils is built with MinGW-w64. Thus GNU LGPLv2.1 doesn't apply.)
|
|
|
|
|
|
Package contents
|
|
----------------
|
|
|
|
All executables and libraries in this package require msvcrt.dll,
|
|
not Universal CRT (UCRT).
|
|
|
|
There is a SSE2 optimization in the compression code but this
|
|
version of XZ Utils doesn't include run-time processor detection.
|
|
This is why there is a separate i686-SSE2 version.
|
|
|
|
There is one directory for each type of executable and library files:
|
|
|
|
bin_i686 32-bit x86 (i686 and newer), Windows 2000 and later
|
|
bin_i686-sse2 32-bit x86 (i686 with SSE2), Windows 2000 and later
|
|
bin_x86-64 64-bit x86-64, Windows Vista and later
|
|
|
|
Each of the above directories have the following files:
|
|
|
|
*.exe Command line tools. (It's useless to double-click
|
|
these; use the command prompt instead.) These have
|
|
been linked statically against liblzma, so they
|
|
don't require liblzma.dll. Thus, you can copy e.g.
|
|
xz.exe to a directory that is in PATH without
|
|
copying any other files from this package.
|
|
|
|
NOTE: xzdec.exe and lzmadec.exe are optimized for
|
|
size, single-threaded, and slower than xz.exe.
|
|
Use xz.exe unless program size is important.
|
|
|
|
liblzma.dll Shared version of the liblzma compression library.
|
|
This file is mostly useful to developers, although
|
|
some non-developers might use it to upgrade their
|
|
copy of liblzma.
|
|
|
|
The rest of the directories contain architecture-independent files:
|
|
|
|
doc Basic documentation in the plain text (TXT)
|
|
format. COPYING.txt, COPYING.0BSD.txt, and
|
|
COPYING.MinGW-w64-runtime.txt contain
|
|
copyright and license information.
|
|
liblzma.def is in this directory too.
|
|
|
|
doc/manuals The manuals of the command line tools in
|
|
plain text (TXT) format.
|
|
|
|
doc/api liblzma API documentation in HTML format.
|
|
|
|
doc/examples Example programs for basic liblzma usage.
|
|
|
|
include C header files for liblzma. These should be
|
|
compatible with most C and C++ compilers.
|
|
|
|
|
|
Creating an import library for MSVC / Visual Studio
|
|
---------------------------------------------------
|
|
|
|
To link against liblzma.dll, you need to create an import library
|
|
first. You need the "lib" command from MSVC and liblzma.def from
|
|
the "doc" directory of this package. Here is the command that works
|
|
on 32-bit x86:
|
|
|
|
lib /def:liblzma.def /out:liblzma.lib /machine:ix86
|
|
|
|
On x86-64, the /machine argument has to be changed:
|
|
|
|
lib /def:liblzma.def /out:liblzma.lib /machine:x64
|
|
|
|
IMPORTANT: See also the file liblzma-crt-mixing.txt.
