Hello Vincent,
Sorry, was on vacation and pretty busy, but back now. On the topic of the
Meson build, here's my latest update. This version has many improvements:
- Proper pkg-config freetype2.pc generation and installation.
- Fixed shared library install suffix to match libtool-generated one
(number computed from the version_info in build/unix/configure.raw).
- Auto-generation of ftmodule.h and list of base extensions, based on
modules.cfg
- Generation of reference documentation (with "docs" target, but only
inside the build directory).
The last remaining todo is the ability to create a distribution package,
though that might be handled by an independent script as well, since it
needs to run "autogen.sh" in a temporary directory.
Can you tell me about the Windows compilation failure? mmap() should not be
an issue due to the checks in the build.meson file which should use
src/base/ftsystem.c for Windows.
I've setup a Window virtual machine and will start testing with it soon.
Regards
- David

Subject: [build] Add Meson build project files.
This adds a few files to build the FreeType 2 library
with the Meson build system:
- meson.build: top-level Meson build file for the library.
- meson_options.txt: user-selectable options for the build.
These can be printed with 'meson configure', and selected
as 'meson setup' or 'meson --reconfigure' time with
-D<option>=<value>.
- builds/meson/ft{config,option}.h.in: template versions
of ftconfig.h and ftoption.h to be used by the Meson build.
These are processed by Meson, which will turn #mesondefine
statements into #define / #undef depending on build
configuration.
- scripts/extract_freetype_version.py: A script invoked by
meson.build to extract the FreeType version number from
<freetype/freetype.h>
- scripts/extract_libtool_version.py: A script invoked by
meson.build to extract the libtool revision_info from
builds/unix/configure.raw and generate the corresponding
shared library suffix.
- scripts/generate_reference_docs.py: A script invoked
by meson.build to generate the FreeType 2 reference
documentation (using the docwriter / mkdocs packages
which must be installed previously).
Example usage:
# Configure Meson build to generate release binaries comparable to
# to the ones from the autotools/make build system.
meson setup build-meson --prefix=/ --buildtype=release --optimization=2 --strip
# Build and install to /tmp/aa/, this includes a pkg-config file.
DESTDIR=/tmp/aa ninja -C build-meson install
# Generate documentation under build-meson/docs
ninja -C build-meson docs
Library size comparison for stripped libfreetype.so generated
by all three build systems:
- Default build (autotools + libtool): 712 KiB
- CMake build (RelWithDebInfo): 712 KiB
- Meson build: 784 KiB

+ * USER-SELECTABLE CONFIGURATION MACROS
+ *
+ * This file contains the default configuration macro definitions for a
+ * standard build of the FreeType library. There are three ways to use
+ * this file to build project-specific versions of the library:
+ *
+ * - You can modify this file by hand, but this is not recommended in
+ * cases where you would like to build several versions of the library
+ * from a single source directory.
+ *
+ * - You can put a copy of this file in your build directory, more
+ * precisely in `$BUILD/freetype/config/ftoption.h`, where `$BUILD` is
+ * the name of a directory that is included _before_ the FreeType include
+ * path during compilation.
+ *
+ * The default FreeType Makefiles and Jamfiles use the build directory
+ * `builds/<system>` by default, but you can easily change that for your
+ * own projects.
+ *
+ * - Copy the file <ft2build.h> to `$BUILD/ft2build.h` and modify it
+ * slightly to pre-define the macro `FT_CONFIG_OPTIONS_H` used to locate
+ * this file during the build. For example,
+ *
+ * ```
+ * #define FT_CONFIG_OPTIONS_H <myftoptions.h>
+ * #include <freetype/config/ftheader.h>
+ * ```
+ *
+ * will use `$BUILD/myftoptions.h` instead of this file for macro
+ * definitions.
+ *
+ * Note also that you can similarly pre-define the macro
+ * `FT_CONFIG_MODULES_H` used to locate the file listing of the modules
+ * that are statically linked to the library at compile time. By
+ * default, this file is `<freetype/config/ftmodule.h>`.
+ *
+ * We highly recommend using the third method whenever possible.

+ * TrueType hinting mechanism when anything but `FT_RENDER_MODE_MONO` is
+ * requested.
+ *
+ * In particular, it modifies the bytecode interpreter to interpret (or
+ * not) instructions in a certain way so that all TrueType fonts look like
+ * they do in a Windows ClearType (DirectWrite) environment. See [1] for a
+ * technical overview on what this means. See `ttinterp.h` for more
+ * details on the LEAN option.
+ *
+ * There are three possible values.
+ *
+ * Value 1:
+ * This value is associated with the 'Infinality' moniker, contributed by
+ * an individual nicknamed Infinality with the goal of making TrueType
+ * fonts render better than on Windows. A high amount of configurability
+ * and flexibility, down to rules for single glyphs in fonts, but also
+ * very slow. Its experimental and slow nature and the original
+ * developer losing interest meant that this option was never enabled in
+ * default builds.
+ *
+ * The corresponding interpreter version is v38.
+ *
+ * Value 2:
+ * The new default mode for the TrueType driver. The Infinality code
+ * base was stripped to the bare minimum and all configurability removed
+ * in the name of speed and simplicity. The configurability was mainly
+ * aimed at legacy fonts like 'Arial', 'Times New Roman', or 'Courier'.
+ * Legacy fonts are fonts that modify vertical stems to achieve clean
+ * black-and-white bitmaps. The new mode focuses on applying a minimal
+ * set of rules to all fonts indiscriminately so that modern and web
+ * fonts render well while legacy fonts render okay.
+ *
+ * The corresponding interpreter version is v40.
+ *
+ * Value 3:
+ * Compile both, making both v38 and v40 available (the latter is the
+ * default).
+ *
+ * By undefining these, you get rendering behavior like on Windows without
+ * ClearType, i.e., Windows XP without ClearType enabled and Win9x
+ * (interpreter version v35). Or not, depending on how much hinting blood
+ * and testing tears the font designer put into a given font. If you
+ * define one or both subpixel hinting options, you can switch between
+ * between v35 and the ones you define (using `FT_Property_Set`).
+ *
+ * This option requires `TT_CONFIG_OPTION_BYTECODE_INTERPRETER` to be
