Building XZ Utils on Windows
|
|
============================
|
|
|
|
Introduction
|
|
------------
|
|
|
|
This document explains shortly where to get and how to install the
|
|
build tools that are needed to build XZ Utils on Windows. The final
|
|
binary package will be standalone in sense that it will depend only
|
|
on DLLs that are included in all Windows installations.
|
|
|
|
These instructions don't apply to Cygwin. XZ Utils can be built under
|
|
Cygwin in the same way as many other packages.
|
|
|
|
These instructions don't apply to MinGW and MSYS developers either,
|
|
who may want to package XZ Utils for MinGW or MSYS distributions.
|
|
You know who you are, and will probably use quite different configure
|
|
options etc. than what is described here.
|
|
|
|
|
|
Installing the toolchain(s)
|
|
---------------------------
|
|
|
|
Some of the following is needed:
|
|
- MSYS is always needed to use the GNU Autotools based build system.
|
|
- MinGW builds 32-bit x86 binaries.
|
|
- 32-bit MinGW-w64 (I call it MingW-w32 here) builds 32-bit x86
|
|
executables too.
|
|
- MinGW-w64 builds 64-bit x86-64 binaries.
|
|
|
|
So you need to pick between MinGW and MinGW-w32 when building
|
|
32-bit version. You don't need both.
|
|
|
|
You might find 7-Zip <https://7-zip.org/> handy when extracting
|
|
some files. The ready-made build script build.bash will also use
|
|
7-Zip to create the distributable .zip and .7z files.
|
|
|
|
I used the following directory structure but you can use whatever
|
|
you want. Just note that I will use these in my examples. Each of
|
|
these should have a subdirectory "bin":
|
|
|
|
C:\devel\tools\msys
|
|
C:\devel\tools\mingw
|
|
C:\devel\tools\mingw-w32
|
|
C:\devel\tools\mingw-w64
|
|
|
|
|
|
Installing MSYS
|
|
|
|
You can download MSYS from MinGW's Sourceforge page:
|
|
|
|
https://sourceforge.net/projects/mingw/files/MSYS/Base/msys-core/
|
|
|
|
I recommend using MSYS 1.0.11 (MSYS-1.0.11.exe or
|
|
msysCORE-1.0.11-bin.tar.gz) because that package includes all the
|
|
required tools. At least some of the later versions include only
|
|
a subset and thus you would need to download the rest separately.
|
|
The old version will work fine for building XZ Utils.
|
|
|
|
You can use either the .exe or .tar.gz package. I prefer .tar.gz,
|
|
because it can be extracted into any directory and later removed
|
|
without worrying about uninstallers.
|
|
|
|
|
|
Installing MinGW
|
|
|
|
NOTE: This section may be outdated. I haven't tried MinGW recently.
|
|
|
|
You can download the required packages from MinGW's Sourceforge page:
|
|
|
|
https://sourceforge.net/projects/mingw/files/
|
|
|
|
These version numbers were the latest when I wrote this document, but
|
|
you probably should pick the latest versions:
|
|
|
|
MinGW Runtime -> mingwrt-3.17-mingw32-dev.tar.gz
|
|
MinGW API for MS-Windows -> w32api-3.14-mingw32-dev.tar.gz
|
|
GNU Binutils -> binutils-2.20-1-bin.tar.gz
|
|
GCC Version 4 -> gcc-full-4.4.0-mingw32-bin-2.tar.lzma
|
|
|
|
The full GCC package is quite big, but if you want a smaller
|
|
download, you will need to download more than one file, so I'm
|
|
using the full package in this document for simplicity.
|
|
|
|
Extract the packages in the above order, possibly overwriting files
|
|
from packages that were extracted earlier.
|
|
|
|
|
|
Installing MinGW-w32 or MinGW-w64
|
|
|
|
I used the packages from Mingw-builds project. With that it is
|
|
enough to pick one .7z file for 32-bit and another for 64-bit
|
|
toolchain. For XZ Utils 5.2.0 I used the packages from these
|
|
directories:
|
|
|
|
https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/mingw-builds/4.9.2/threads-win32/sjlj/
|
|
|
|
https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/4.9.2/threads-win32/sjlj/
|
|
|
|
If you install both MinGW-w32 and MinGW-w64, remember to extract
|
|
them into different directories. build.bash looks at
|
|
C:\devel\tools\mingw-w32 and C:\devel\tools\mingw-w64 by default.
|
|
|
|
|
|
Building XZ Utils
|
|
-----------------
|
|
|
|
Start MSYS by going to the directory C:\devel\tools\msys and running
|
|
msys.bat there (double-click or use command prompt). It will start
|
|
at "home" directory, which is C:\devel\tools\msys\home\YourUserName.
|
|
|
|
If you have xz-5.x.x.tar.gz in C:\devel, you should be able to build
|
|
it now with the following commands:
|
|
|
|
cd /c/devel
|
|
tar xzf xz-5.x.x.tar.gz
|
|
cd xz-5.x.x
|
|
bash windows/build.bash
|
|
|
|
If you used some other directory than C:\devel\tools for the build
|
|
tools, edit the variables near the beginning of build.bash first.
|
|
|
|
If you want to build manually, read the buildit() function in
|
|
build.bash. Look especially at the latter configure invocation.
|
|
|
|
Be patient. Running configure and other scripts used by the build
|
|
system is (very) slow under Windows.
|
|
|
|
|
|
Using a snapshot from the Git repository
|
|
|
|
To use a snapshot, the build system files need to be generated with
|
|
autogen.sh or "autoreconf -fi" before trying to build using the
|
|
above build instructions. You can install the relevant extra packages
|
|
from MinGW or use Cygwin or use e.g. a GNU/Linux system to create a
|
|
source package with the required build system files.
