- # Expat, Release 2.7.1
++# Expat, Release 2.7.2
+
+This is Expat, a C99 library for parsing
+[XML 1.0 Fourth Edition](https://www.w3.org/TR/2006/REC-xml-20060816/), started by
+[James Clark](https://en.wikipedia.org/wiki/James_Clark_%28programmer%29) in 1997.
+Expat is a stream-oriented XML parser. This means that you register
+handlers with the parser before starting the parse. These handlers
+are called when the parser discovers the associated structures in the
+document being parsed. A start tag is an example of the kind of
+structures for which you may register handlers.
+
+Expat supports the following C99 compilers:
+
+- GNU GCC >=4.5 (for use from C) or GNU GCC >=4.8.1 (for use from C++)
+- LLVM Clang >=3.5
- - Microsoft Visual Studio >=16.0/2019 (rolling `${today} minus 5 years`)
++- Microsoft Visual Studio >=17.0/2022
++ (the oldest version supported by the [official GitHub Actions Windows images](https://github.com/actions/runner-images))
+
+Windows users can use the
+[`expat-win32bin-*.*.*.{exe,zip}` download](https://github.com/libexpat/libexpat/releases),
+which includes both pre-compiled libraries and executables, and source code for
+developers.
+
+Expat is [free software](https://www.gnu.org/philosophy/free-sw.en.html).
+You may copy, distribute, and modify it under the terms of the License
+contained in the file
+[`COPYING`](https://github.com/libexpat/libexpat/blob/master/expat/COPYING)
+distributed with this package.
+This license is the same as the MIT/X Consortium license.
+
+
+## Using libexpat in your CMake-Based Project
+
+There are three documented ways of using libexpat with CMake:
+
+### a) `find_package` with Module Mode
+
+This approach leverages CMake's own [module `FindEXPAT`](https://cmake.org/cmake/help/latest/module/FindEXPAT.html).
+
+Notice the *uppercase* `EXPAT` in the following example:
+
+```cmake
+cmake_minimum_required(VERSION 3.10)
+
+project(hello VERSION 1.0.0)
+
+find_package(EXPAT 2.2.8 MODULE REQUIRED)
+
+add_executable(hello
+ hello.c
+)
+
+target_link_libraries(hello PUBLIC EXPAT::EXPAT)
+```
+
+### b) `find_package` with Config Mode
+
+This approach requires files from…
+
+- libexpat >=2.2.8 where packaging uses the CMake build system
+or
+- libexpat >=2.3.0 where packaging uses the GNU Autotools build system
+ on Linux
+or
+- libexpat >=2.4.0 where packaging uses the GNU Autotools build system
+ on macOS or MinGW.
+
+Notice the *lowercase* `expat` in the following example:
+
+```cmake
+cmake_minimum_required(VERSION 3.10)
+
+project(hello VERSION 1.0.0)
+
+find_package(expat 2.2.8 CONFIG REQUIRED char dtd ns)
+
+add_executable(hello
+ hello.c
+)
+
+target_link_libraries(hello PUBLIC expat::expat)
+```
+
+### c) The `FetchContent` module
+
+This approach — as demonstrated below — requires CMake >=3.18 for both the
+[`FetchContent` module](https://cmake.org/cmake/help/latest/module/FetchContent.html)
+and its support for the `SOURCE_SUBDIR` option to be available.
+
+Please note that:
+- Use of the `FetchContent` module with *non-release* SHA1s or `master`
+ of libexpat is neither advised nor considered officially supported.
+- Pinning to a specific commit is great for robust CI.
+- Pinning to a specific commit needs updating every time there is a new
+ release of libexpat — either manually or through automation —,
+ to not miss out on libexpat security updates.
+
+For an example that pulls in libexpat via Git:
+
+```cmake
+cmake_minimum_required(VERSION 3.18)
+
+include(FetchContent)
+
+project(hello VERSION 1.0.0)
+
+FetchContent_Declare(
+ expat
+ GIT_REPOSITORY https://github.com/libexpat/libexpat/
+ GIT_TAG 000000000_GIT_COMMIT_SHA1_HERE_000000000 # i.e. Git tag R_0_Y_Z
+ SOURCE_SUBDIR expat/
+)
+
+FetchContent_MakeAvailable(expat)
+
+add_executable(hello
+ hello.c
+)
+
+target_link_libraries(hello PUBLIC expat)
+```
+
+
+## Building from a Git Clone
+
+If you are building Expat from a check-out from the
+[Git repository](https://github.com/libexpat/libexpat/),
+you need to run a script that generates the configure script using the
+GNU autoconf and libtool tools. To do this, you need to have
+autoconf 2.58 or newer. Run the script like this:
+
+```console
+./buildconf.sh
+```
+
+Once this has been done, follow the same instructions as for building
+from a source distribution.
+
+
+## Building from a Source Distribution
+
+### a) Building with the configure script (i.e. GNU Autotools)
+
+To build Expat from a source distribution, you first run the
+configuration shell script in the top level distribution directory:
+
+```console
+./configure
+```
+
+There are many options which you may provide to configure (which you
+can discover by running configure with the `--help` option). But the
+one of most interest is the one that sets the installation directory.
+By default, the configure script will set things up to install
+libexpat into `/usr/local/lib`, `expat.h` into `/usr/local/include`, and
+`xmlwf` into `/usr/local/bin`. If, for example, you'd prefer to install
+into `/home/me/mystuff/lib`, `/home/me/mystuff/include`, and
+`/home/me/mystuff/bin`, you can tell `configure` about that with:
+
+```console
+./configure --prefix=/home/me/mystuff
+```
+
+Another interesting option is to enable 64-bit integer support for
+line and column numbers and the over-all byte index:
+
+```console
+./configure CPPFLAGS=-DXML_LARGE_SIZE
+```
+
+However, such a modification would be a breaking change to the ABI
+and is therefore not recommended for general use — e.g. as part of
+a Linux distribution — but rather for builds with special requirements.
+
+After running the configure script, the `make` command will build
+things and `make install` will install things into their proper
+location. Have a look at the `Makefile` to learn about additional
+`make` options. Note that you need to have write permission into
+the directories into which things will be installed.
+
+If you are interested in building Expat to provide document
+information in UTF-16 encoding rather than the default UTF-8, follow
+these instructions (after having run `make distclean`).
+Please note that we configure with `--without-xmlwf` as xmlwf does not
+support this mode of compilation (yet):
+
+1. Mass-patch `Makefile.am` files to use `libexpatw.la` for a library name:
+ <br/>
+ `find . -name Makefile.am -exec sed
+ -e 's,libexpat\.la,libexpatw.la,'
+ -e 's,libexpat_la,libexpatw_la,'
+ -i.bak {} +`
+
+1. Run `automake` to re-write `Makefile.in` files:<br/>
+ `automake`
+
+1. For UTF-16 output as unsigned short (and version/error strings as char),
+ run:<br/>
+ `./configure CPPFLAGS=-DXML_UNICODE --without-xmlwf`<br/>
+ For UTF-16 output as `wchar_t` (incl. version/error strings), run:<br/>
+ `./configure CFLAGS="-g -O2 -fshort-wchar" CPPFLAGS=-DXML_UNICODE_WCHAR_T
+ --without-xmlwf`
+ <br/>Note: The latter requires libc compiled with `-fshort-wchar`, as well.
+
+1. Run `make` (which excludes xmlwf).
+
+1. Run `make install` (again, excludes xmlwf).
+
+Using `DESTDIR` is supported. It works as follows:
+
+```console
+make install DESTDIR=/path/to/image
+```
+
+overrides the in-makefile set `DESTDIR`, because variable-setting priority is
+
+1. commandline
+1. in-makefile
+1. environment
+
+Note: This only applies to the Expat library itself, building UTF-16 versions
+of xmlwf and the tests is currently not supported.
+
+When using Expat with a project using autoconf for configuration, you
+can use the probing macro in `conftools/expat.m4` to determine how to
+include Expat. See the comments at the top of that file for more
+information.
+
+A reference manual is available in the file `doc/reference.html` in this
+distribution.
+
+
+### b) Building with CMake
+
+The CMake build system is still *experimental* and may replace the primary
+build system based on GNU Autotools at some point when it is ready.
+
+
+#### Available Options
+
+For an idea of the available (non-advanced) options for building with CMake:
+
+```console
+# rm -f CMakeCache.txt ; cmake -D_EXPAT_HELP=ON -LH . | grep -B1 ':.*=' | sed 's,^--$,,'
+// Choose the type of build, options are: None Debug Release RelWithDebInfo MinSizeRel ...
+CMAKE_BUILD_TYPE:STRING=
+
+// Install path prefix, prepended onto install directories.
+CMAKE_INSTALL_PREFIX:PATH=/usr/local
+
+// Path to a program.
+DOCBOOK_TO_MAN:FILEPATH=/usr/bin/docbook2x-man
+
+// Build man page for xmlwf
+EXPAT_BUILD_DOCS:BOOL=ON

+EXPAT_ENABLE_INSTALL:BOOL=ON
+
+// Use /MT flag (static CRT) when compiling in MSVC
+EXPAT_MSVC_STATIC_CRT:BOOL=OFF
+
+// Build fuzzers via OSS-Fuzz for the expat library
+EXPAT_OSSFUZZ_BUILD:BOOL=OFF
+
+// Build a shared expat library
+EXPAT_SHARED_LIBS:BOOL=ON

+EXPAT_WITH_LIBBSD:BOOL=OFF
+
+// Make use of syscall SYS_getrandom (ON|OFF|AUTO) [default=AUTO]

+```
