WINDOWS DISTRIBUTION
-For the convenience of Windows users, the Windows distribution of wimlib is a
-ZIP file containing the following items:
+The Windows distribution of wimlib is a ZIP file containing the following items:
* wimlib-imagex.exe, a command-line tool to deal with WIM (.wim), split WIM
(.swm), and ESD (.esd) files that is inspired by Microsoft's ImageX and
* Very short batch scripts (e.g. wimapply.cmd) which are shortcuts to the
corresponding wimlib-imagex commands (e.g. `wimlib-imagex apply').
+ * The library itself in DLL format (libwim-15.dll). wimlib-imagex.exe
+ requires this to run.
+
* The documentation, including this file, the generic README.txt, and
PDF documentation for wimlib-imagex in the 'doc' directory.
- * The library itself (libwim-15.dll). The C header wimlib.h is not
- included; download the source if you want it.
-
* License files for all software included. These are all free software
- licenses.
+ licenses. COPYING.txt is the main license, and it refers to
+ COPYING.GPLv3.txt and COPYING.LGPLv3.txt. The other licenses are for
+ third-party software included in the library.
+
+ * Development files in the 'devel' directory. These are only needed if you
+ are developing C or C++ applications that use wimlib.
+
+Note that there are separate ZIP files for 32-bit (i686) and 64-bit (x86_64)
+binaries. They are both fully supported, but you should prefer the 64-bit
+binaries when possible as they can be noticeably faster.
WIMLIB-IMAGEX
-wimlib-imagex provides most features of Microsoft's ImageX, plus additional
-features. Perhaps the main limitation is that mounting images from a WIM file
-is not supported on Windows. However, wimlib-imagex provides a number of
-advantages compared to Microsoft's ImageX, including but not limited to the
-following:
+wimlib-imagex supports most features of Microsoft's ImageX as well as some
+features that are supported by DISM but not by ImageX. wimlib-imagex also
+supports some features that neither ImageX nor DISM support. Some of the
+advantages of wimlib-imagex compared to ImageX and DISM are:
- * wimlib-imagex provides "extract" and "update" commands that can be used to
- work around the lack of mount support. These commands are very fast
- compared to mounting and unmounting images with Microsoft's ImageX, so you
- may prefer them anyway.
+ * wimlib-imagex provides "extract" and "update" commands which allow
+ you to quickly work with WIM images without mounting them.
- * wimlib-imagex provides an easy-to-use "optimize" command to remove wasted
- space from WIM files.
+ * wimlib-imagex provides an easy-to-use "optimize" command which removes
+ wasted space from a WIM file and optionally recompresses it with stronger
+ compression.
- * In some cases, wimlib-imagex uses simpler command-line syntax. For
- example, integrity tables are treated as persistent, and in some cases image
- names need not be explicitly specified.
+ * wimlib includes advanced implementations of all compression algorithms used
+ in WIM files. They usually outperform and outcompress their Microsoft
+ equivalents.
- * Whenever possible, wimlib-imagex includes improved documentation and
- informational output compared to Microsoft's software.
+ * wimlib-imagex supports solid WIM files and LZMS compression, for example as
+ used in ESD (.esd) files. (These are partially supported by recent DISM
+ versions but not by ImageX.)
- * On Windows, wimlib-imagex can correctly save and restore some combinations
- of data that Microsoft's ImageX runs into bugs on --- for example,
- uncompressed files in compressed directories, or files with alternate data
- streams and multiple hard links.
+ * wimlib-imagex supports imaging a live Windows system. Just use the
+ --snapshot option.
- * wimlib-imagex also supports ESD (.esd) files, except when encrypted. (These
- use a newer version of the WIM file format.)
+ * In many cases, wimlib-imagex has simpler command-line syntax than either
+ ImageX or DISM.
+
+ * Whenever possible, wimlib-imagex includes improved documentation and
+ informational output compared to Microsoft's software.
* wimlib and wimlib-imagex are free software, so you can modify and/or audit
the source code.
+However, some limitations of wimlib-imagex compared to ImageX and DISM are:
+
+ * On Windows, wimlib-imagex does not support mounting WIM images.
+
+ * wimlib-imagex has no awareness of Windows "packages".

+ BUILDING FROM SOURCE
+
+As with other open source software, advanced users may choose to build wimlib
+from source, potentially with customizations. Although wimlib's build system is
+designed for UNIX-like systems and is easiest to use on Linux, it's possible to
+build Windows binaries on Windows using Cygwin with MinGW. To do this, follow
+the instructions below. For the sake of example, I'll assume you are building a
+64-bit version of wimlib v1.11.0.
+
+Run the Cygwin installer, available from https://www.cygwin.com/setup-x86.exe.
+When you get to the package selection screen, choose the following additional
+packages from category "Devel":
+
+ - make
+ - mingw64-x86_64-binutils
+ - mingw64-x86_64-gcc-g++
+ - mingw64-x86_64-libxml2
+ - mingw64-x86_64-pkg-config
+ - mingw64-x86_64-winpthreads
+
+Download wimlib's source code from https://wimlib.net/downloads/wimlib-1.11.0.tar.gz.
+
+Start a Cygwin terminal and run the following commands:
+
+ cd /cygdrive/c/Users/example/Downloads # (or wherever you downloaded the source to)
+ tar xf wimlib-1.11.0.tar.gz
+ cd wimlib-1.11.0
+ ./configure --host=x86_64-w64-mingw32
+ make
+
+If successful, the new binaries "libwim-15.dll" and "wimlib-imagex.exe" will
+have been produced in the .libs directory.
+
+By default the binaries are built with debug symbols. If desired, you can use
+x86_64-w64-mingw32-strip to strip them.
+
+libwim-15.dll will be linked to several other DLLs which you will need as well:
+
+ - libwinpthread-1.dll
+ - libxml2-2.dll, which also requires:
+ - iconv.dll
+ - liblzma-5.dll
+ - zlib1.dll
+
+These DLLs can be found in "C:\cygwin\usr\x86_64-w64-mingw32\sys-root\mingw\bin"
+and must be placed alongside libwim-15.dll for it to run portably. But see
+below for an alternative.
+
+Building 32-bit binaries is very similar, but you'll need to replace "x86_64"
+with "i686" everywhere in the above instructions, and libwim-15.dll will also
+depend on libgcc_s_sjlj-1.dll. Note that you can build both 32-bit and 64-bit
+binaries from the same Cygwin installation, provided that you install both the
+mingw64-i686-* and mingw64-x86_64-* packages; and you can run the Cygwin setup
+program to install more packages at any time.
+
+In the official binary releases from wimlib.net, libwim-15.dll's dependent
+libraries are linked in statically rather than dynamically, so it does not
+depend on any DLLs other than standard Windows DLLs. If you want to do this,
+install the following additional Cygwin packages:
+
+ - p7zip (category "Archiver")
+ - autoconf (category "Devel")
+ - automake (category "Devel")
+ - git (category "Devel")
+ - libtool (category "Devel")
+ - nasm (category "Devel")
+ - pkg-config (category "Devel")
+ - ghostscript (category "Graphics")
+ - wget (category "Web")
+
+Then, in a Cygwin terminal, clone the git repository, checkout the wimlib
+version you want, bootstrap the repository, and run the Windows release script:
+
+ git clone git://wimlib.net/wimlib
+ cd wimlib
+ git checkout v1.11.0
+ ./bootstrap
+ ./tools/make-windows-release x86_64
+
+The release script will download and build libxml2 and winpthreads as static
+libraries, then build wimlib, then do some final tasks and bundle the resulting
+files up into a ZIP archive. If successful you'll end up with a file like
+"wimlib-1.11.0-windows-x86_64-bin.zip", just like the official releases. For
+32-bit binaries just use "i686" instead of "x86_64".
