The Pango backends written for Win32 is pangowin32. Pangowin32 uses
the Win32 GDI font API. GTK+ 2.8 and later on Win32 however actually
uses the pangocairo backend (which then uses only small parts of
pangowin32). Much of the GDI font API calls are in cairo.

The pangoft2 backend was originally written with Win32 in mind, but
its main use nowadays is on other platforms than Win32.

To build Pango for Win32:

You need to have gcc (mingw) or Visual Studio 2008~2017, along with
Python 3.4.x+ and Meson 0.43.0.  If building the introspection files,
you will also need to ensure that the Python release series and
build architecture (i.e. Win32 (x86)/x64 (amd64/x86-64) matches the
Python release series and build architecture that was used to build
GObject-Introspection.  The Python interpreter executable directory
must be in your PATH.  The Ninja build utility must also be in your
PATH, unless using the Visual Studio IDE as noted below.

You will also need the following libraries installed with their headers
and import libraries, and their DLLs, if applicable, needs to be found in
%PATH%.  All of their required dependencies are required as well.  Their
pkg-config files are needed on all builds unless marked with a *, where
only their headers/import libraries are needed on Visual Studio:

-GLib
-Fribidi
-Cairo* (With Win32 support built in, and optionally FreeType and FontConfig
         support for building PangoFT2.)
-FreeType* (Optional, needed for PangoFT2)
-FontConfig* (Optional, needed for PangoFT2)
-HarfBuzz* (Optional, GLib and FreeType support required if used, needed for PangoFT2)

Please see meson.build to see what versions are needed for these dependencies.

Follow the following steps to build Pango:

1) Invoke the Meson configuration as follows, in a directory separate from the sources:

(With MinGW, please adjust the paths accordingly, in a MSYS/MSYS2 bash prompt)
PATH=/devel/dist/glib-2.8.0/bin:$PATH ACLOCAL_FLAGS="-I /devel/dist/glib-2.8.0/share/aclocal" PKG_CONFIG_PATH=/devel/dist/glib-2.8.0/lib/pkgconfig:$PKG_CONFIG_PATH CC='gcc -mtune=pentium3' CPPFLAGS='-I/opt/gnu/include' LDFLAGS='-L/opt/gnu/lib' CFLAGS=-O meson $(PATH_TO_SRC) --buildtype=$(buildtype) --prefix=$(PREFIX)

(With Visual Studio, set the INCLUDE, LIB, PATH and PKG_CONFIG_PATH envvars as
needed before running the following in a Visual Studio command prompt)
python $(PATH_TO_meson.py) $(PATH_TO_SRC) --buildtype=$(buildtype) --prefix=$(PREFIX)

For Visual Studio builds, building using the Visual Studio IDE is also supported
with Visual Studio 2010, 2015 and 2017.  Append --backend=vs to the Meson
configuration command above to use this support.

2) Build Pango by running Ninja, or by opening and building the generated
   Visual Studio 2010/2015/2017 solution file.
	
3) Run tests and/or install the build using the "test" and "install" targets
   or sub-projects respectively.

4) If building with Visual Studio 2008, you will need to do the run the following
   lines in the Visual Studio or SDK command prompt after building and installing.
   From the build directory:
   for /f %a in (*.dll.manifest) do if exist $(PREFIX)\bin\%~na /manifest %a /outputresource:$(PREFIX)\bin\%~na;2
   for /f %a in (*.exe.manifest) do if exist $(PREFIX)\bin\%~na /manifest %a /outputresource:$(PREFIX)\bin\%~na;1
   for /f %a in (*.exe.manifest) do if exist $(PREFIX)\libexec\installed-tests\pango\%~na /manifest %a /outputresource:$(PREFIX)\libexec\installed-tests\pango\%~na;1
   
   So that the security manifests that are generated can be embedded into the built
   DLLs and EXEs so that they can be usable.

Pango's dependencies with Visual Studio:
