8 This package includes command line tools (xz.exe and a few
9 others) and the liblzma compression library from XZ Utils.
10 You can find the latest version and full source code from
11 <https://tukaani.org/xz/>.
13 The parts of the XZ Utils source code, that are relevant to this
14 binary package, are under the BSD Zero Clause License (0BSD).
15 XZ Utils have been built using GCC and MinGW-w64 and linked
16 statically against the MinGW-w64 runtime libraries. See
17 COPYING.MinGW-w64-runtime.txt for copyright and license
18 information that applies to the MinGW-w64 runtime.
20 IMPORTANT: You must include COPYING.MinGW-w64-runtime.txt
21 when distributing these XZ Utils binaries to meet
22 the license terms of the MinGW-w64 runtime!
24 (The file COPYING mentions GNU getopt_long. It's *not* used when
25 XZ Utils is built with MinGW-w64. Thus GNU LGPLv2.1 doesn't apply.)
31 All executables and libraries in this package require
32 Universal CRT (UCRT). It is included in Windows 10 and later.
34 There is a SSE2 optimization in the compression code but this
35 version of XZ Utils doesn't include run-time processor detection.
36 The binaries don't work on 32-bit processors without SSE2 support.
38 There is one directory for each type of executable and library files:
40 bin_i686-sse2 32-bit x86 (i686 with SSE2)
41 bin_x86-64 64-bit x86-64
43 Each of the above directories have the following files:
45 *.exe Command line tools. (It's useless to double-click
46 these; use the command prompt instead.) These have
47 been linked statically against liblzma, so they
48 don't require liblzma.dll. Thus, you can copy e.g.
49 xz.exe to a directory that is in PATH without
50 copying any other files from this package.
52 NOTE: xzdec.exe and lzmadec.exe are optimized for
53 size, single-threaded, and slower than xz.exe.
54 Use xz.exe unless program size is important.
56 liblzma.dll Shared version of the liblzma compression library.
57 This file is mostly useful to developers, although
58 some non-developers might use it to upgrade their
61 The rest of the directories contain architecture-independent files:
63 doc Basic documentation in the plain text (TXT)
64 format. COPYING.txt, COPYING.0BSD.txt, and
65 COPYING.MinGW-w64-runtime.txt contain
66 copyright and license information.
67 liblzma.def is in this directory too.
69 doc/manuals The manuals of the command line tools
71 doc/examples Example programs for basic liblzma usage.
73 include C header files for liblzma. These should be
74 compatible with most C and C++ compilers.
77 Creating an import library for MSVC / Visual Studio
78 ---------------------------------------------------
80 To link against liblzma.dll, you need to create an import library
81 first. You need the "lib" command from MSVC and liblzma.def from
82 the "doc" directory of this package. Here is the command that works
85 lib /def:liblzma.def /out:liblzma.lib /machine:ix86
87 On x86-64, the /machine argument has to be changed:
89 lib /def:liblzma.def /out:liblzma.lib /machine:x64
91 IMPORTANT: See also the file liblzma-crt-mixing.txt if your
92 application isn't using UCRT.
