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://xz.tukaani.org/xz-utils/>.
|
|
|
|
The parts of the XZ Utils source code, that are relevant to this
|
|
binary package, are in the public domain. XZ Utils have been built
|
|
for this package with MinGW-w64 and linked statically against its
|
|
runtime libraries. See COPYING-Windows.txt for the copyright and
|
|
license information that applies to the MinGW-w64 runtime. You must
|
|
include it when redistributing these XZ Utils binaries.
|
|
|
|
|
|
Package contents
|
|
----------------
|
|
|
|
All executables and libraries in this package require msvcrt.dll.
|
|
It's included in all recent Windows versions. (On Windows 95 it
|
|
might be missing, but once you get it somewhere, the i686 binaries
|
|
should run even on Windows 95 if the processor is new enough.)
|
|
|
|
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 95 and later
|
|
bin_i686-sse2 32-bit x86 (i686 with SSE2), Windows 98 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.
|
|
|
|
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.
|
|
|
|
liblzma.a Static version of the liblzma compression library.
|
|
This file is useful only for developers.
|
|
|
|
The rest of the directories contain architecture-independent files:
|
|
|
|
doc Documentation in the plain text (TXT) format. The
|
|
manuals of the command line tools are provided also
|
|
in the PDF format. liblzma.def is in this directory
|
|
too.
|
|
|
|
include C header files for liblzma. These should be
|
|
compatible with most C and C++ compilers. If you
|
|
have problems, try to fix it and send your fixes
|
|
upstream, or at least report a bug, thanks.

Linking against liblzma
|
|
-----------------------
|
|
|
|
MinGW
|
|
|
|
If you use MinGW, linking against liblzma.dll or liblzma.a should
|
|
be straightforward. You don't need an import library to link
|
|
against liblzma.dll, and for static linking, you don't need to
|
|
worry about the LZMA_API_STATIC macro.
|
|
|
|
Note that the MinGW distribution includes liblzma. If you are
|
|
building packages that will be part of the MinGW distribution, you
|
|
probably should use the version of liblzma shipped in MinGW instead
|
|
of this package.
|
|
|
|
|
|
Microsoft Visual C++
|
|
|
|
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 naturally be changed:
|
|
|
|
lib /def:liblzma.def /out:liblzma.lib /machine:x64
|
|
|
|
If you need to link statically against liblzma, you should build
|
|
liblzma with MSVC 2013 update 2 or later. Alternatively, if having
|
|
a decompressor is enough, consider using XZ Embedded or LZMA SDK.
|
|
|
|
When you plan to link against static liblzma, you need to tell
|
|
lzma.h to not use __declspec(dllimport) by defining the macro
|
|
LZMA_API_STATIC. You can do it either in the C/C++ code
|
|
|
|
#define LZMA_API_STATIC
|
|
#include <lzma.h>
|
|
|
|
or by adding it to compiler options.
|
|
|
|
|
|
Other compilers
|
|
|
|
If you are using some other compiler, see its documentation how to
|
|
create an import library (if it is needed). If it is simple, I
|
|
might consider including the instructions here.
