+ README: Describe building with Meson and Autotools
+
+ and remove the description of the directory structure,
+ which is not very useful.
+
+2020-03-10 Kjell Ahlstedt <kjellahlstedt@gmail.com>
+
+ examples: Disable deprecated API when building with Meson
+
+ Deprecated SIGCXX API is disabled when example programs are built
+ with Autotools. Do the same when building with Meson.

+ docs/reference/meson.build: Check if perl is found
+
+ Don't use perl.path() when configuring Doxyfile, if perl is not found.
+ Perl is not required, if build-documentation=false.
+ Fixes #53

+
+ meson.build: Change project name, sigc++ -> libsigc++
+
+ Autotools make tarballs called libsigc++-x.y.z.tar.xz. No reason to
+ change that. The leading "lib" is now also restored in some locations
+ in the reference documentation.

+
+ sigc++/meson.build: Library name is sigc-2.0
+
+ Pointed out by Chun-wei Fan in PR #51.
+
+2019-12-29 Chun-wei Fan <fanchunwei@src.gnome.org>
+
+ NMake Makefiles: Separate outdir by toolset version
+
+ This is to reduce the likelihood of accidently mixing DLLs that are
+ linked with different CRTs in the build tree.
+
+ Also clean up rules a bit.
+
+2019-12-29 Chun-wei Fan <fanchunwei@src.gnome.org>
+
+ build: Support NMake builds from Meson tarballs
+
+ This adds inference rules to the NMake Makefiles to also look for the
+ sources that are in untracked/, and to ensure that the generated MSVC
+ build files (sigc++-config.h and sigc.rc) are copied into
+ untracked/MSVC_NMake, so that they can be built properly even with
+ NMake.
+
+2019-12-29 Chun-wei Fan <fanchunwei@src.gnome.org>
+
+ meson: Build Windows .rc files on Windows
+
+ This ensures that on Windows, the version info resources are indeed
+ linked into the libsigc++ DLL.
+
+2019-12-29 Chun-wei Fan <fanchunwei@src.gnome.org>
+
+ meson/Windows: Fix builds when builddir is a subdir of source tree
+
+ It appears that Meson did not construct the paths properly for
+ shutil.copy2() when building in a build directory that is a
+ subdirectory of the sources, when using meson.current_build_dir(),
+ possibly due how path separators are handled.
+
+ Fix this by constructing the paths using project_build_root / 'MSVC_NMake'.
+
+2019-12-29 Chun-wei Fan <fanchunwei@src.gnome.org>
+
+ meson.build: Fix 'meson dist' on Windows
+
+ Since we are assured that we are using Python 3.x on when we run Meson, we
+ do not really need to look for the 'python3' executable, but we could
+ just use whatever Python interpreter that is used to run Meson.
+
+ This will fix situations where it is commonly the case where we may have
+ multiple Python 3.x installations on Windows (www.python.org, and those
+ from Cygwin/mingw-w64), so that Meson really uses one and only one
+ Python installation to run everything that is Python-related, which will
+ thus fix '[meson|ninja] dist' on Visual Studio builds.
+
+2019-12-29 Chun-wei Fan <fanchunwei@src.gnome.org>
+
+ Meson/MSVC: Support builds directly from GIT checkouts
+
+ It appears that if one uses the m4 that is given by mingw-w64 (and
+ perhaps Cygwin), that m4 is enough to generate the sources and headers
+ that we need for the build.
+
+ So, remove the lines saying building directly from GIT checkouts are not
+ supported.
+
+2019-12-24 Chun-wei Fan <fanchunwei@src.gnome.org>
+
+ meson: Ensure symbols are exported on MSVC builds
+
+ Make sure the correct build macros are specified when building
+ libsigc++, so that:
+
+ -The symbols are properly exported
+ -We do not break builds as a result of unecesary warnings
+
+2019-12-24 Chun-wei Fan <fanchunwei@src.gnome.org>
+
+ meson: Relax MSVC version requirement to 2015
+
+ libsigc++ requires a C++-11-compliant compiler, so we can just make the
+ build look for Visual Studio 2015 instead of Visual Studio 2017 15.7.
+
+ Visual Studio 2013 also works, but since it will spew out loads of
+ warnings and the latest C++-11 version of glibmm is not buildable with
+ Visual Studio 2013, let's just require Visual Studio 2015.
+
+2019-12-24 Kjell Ahlstedt <kjellahlstedt@gmail.com>
+
+ Add support for building libsigc++-2.0 with Meson
+
+ libsigc++-2.0 can be built with either Autotools or Meson.
+
+2019-12-10 Kjell Ahlstedt <kjellahlstedt@gmail.com>
+
+ Make libsigc_manual.xml valid
+
+ Fix errors reported by "xmllint --postvalid".
+
+2019-07-03 Kjell Ahlstedt <kjellahlstedt@gmail.com>
+
+ tests/test_track_obj: Fix for clang++
+
+ clang++ complains if private members are unused, so make them protected.
+
+ error: private field 'bar_' is not used [-Werror,-Wunused-private-field]
+

-Compatibility:
+Whenever possible, you should use the official binary packages approved by the
+supplier of your operating system, such as your Linux distribution.
- Compatible compilers must support C++11, such as the decltype() specifier.
+## Building on Windows
- All releases are tested with the gcc (g++) compiler.
- Release 2.3.2 has been tested with gcc 4.8.2, clang 3.4 and MS Visual C++ 2010.
- Release 2.5.1 has been tested with gcc 4.9.2, clang 3.6.0 and MS Visual C++ 2013.
+See MSVC_NMake/README.txt.
+
+## Building from a release tarball
+
+It's easiest to build with Meson, if the tarball was made with Meson,
+and to build with Autotools, if the tarball was made with Autotools.
+Then you don't have to use maintainer-mode.
+
+How do you know how the tarball was made? If it was made with Meson,
+it contains files in untracked/build_scripts/, untracked/docs/ and possibly
+other subdirectories of untracked/.
+
+### Building from a tarball with Meson
+
+Don't call the builddir 'build'. There is a directory called 'build' with
+files used by Autotools.
+
+If the tarball was made with Autotools, you must enable maintainer-mode:
+ $ meson --prefix=/some_directory --libdir=lib -Dmaintainer-mode=true your_builddir .
+If the tarball was made with Meson:
+ $ meson --prefix=/some_directory --libdir=lib your_builddir .
+
+Then
+ $ cd your_builddir
+ $ ninja
+ $ ninja install
+You can run the tests like so:
+ $ ninja test
+
+### Building from a tarball with Autotools
+
+If the tarball was made with Autotools:
+ $ ./configure --prefix=/some_directory
+If the tarball was made with Meson, you must enable maintainer-mode:
+ $ ./autogen.sh --prefix=/some_directory
+
+Then
+ $ make
+ $ make install
+You can build the examples and tests, and run the tests, like so:
+ $ make check
+
+## Building from git
+
+Building from git can be difficult so you should prefer building from
+a release tarball unless you need to work on the libsigc++ code itself.
+
+jhbuild can be a good help
+ https://gitlab.gnome.org/GNOME/jhbuild
+ https://wiki.gnome.org/Projects/Jhbuild
+
+### Building from git with Meson
+
+Maintainer-mode is enabled by default when you build from a git clone.
+
+Don't call the builddir 'build'. There is a directory called 'build' with
+files used by Autotools.
+
+ $ meson --prefix=/some_directory --libdir=lib your_builddir .
+ $ cd your_builddir
+ $ ninja
+ $ ninja install
+You can run the tests like so:
+ $ ninja test
+You can create a tarball like so:
+ $ ninja dist
+
+### Building from git with Autotools
+
+ $ ./autogen.sh --prefix=/some_directory
+ $ make
+ $ make install
+You can build the examples and tests, and run the tests, like so:
+ $ make check
+You can create a tarball like so:
+ $ make distcheck
+or
+ $ make dist

+
+This directory contains files not tracked by a source code control program,
+such as git. (This README file is the exception.)
+
+The files can have one of two origins.
+
+1. Copied by the mm-common-get command.
+2. Generated when libsigc++ is built.
+
+Files of type 2 exist here only if libsigc++ is built with maintainer-mode=false,
+or the directory comes from a tarball.
+Files of both types exist here only if libsigc++ is built with Meson,
+or the tarball is created with Meson.
