This may take a while to build. Feel free to do something else while this is building.

HarfBuzz Dependencies

Recommended

GLib-2.84.0 (required for Pango; GObject Introspection required for building GNOME), ICU-77.1, FreeType-2.13.3 - Pass 1, and Meson Toolchain Files (for lib32)

Installation of HarfBuzz

Install HarfBuzz by running the following commands: 

mkdir build &&
cd    build &&

meson setup ..              \
      --prefix=/usr         \
      --buildtype=release   \
      -D graphite2=disabled \
      -D tests=disabled &&

ninja

Now, as the root user: 

ninja install

lib32 Installation of HarfBuzz

First clean the build directory: 

rm -rf *

Install lib32-HarfBuzz by running the following commands: 

meson setup ..              \
      --cross-file lib32    \
      --prefix=/usr         \
      --libdir=/usr/lib32   \
      --buildtype=release   \
      -D cairo=disabled     \
      -D graphite2=disabled \
      -D tests=disabled &&

ninja

Now, as the root user: 

DESTDIR=$PWD/DESTDIR ninja install    &&
cp -vr DESTDIR/usr/lib32/* /usr/lib32 &&
rm -rf DESTDIR                        &&
ldconfig

Command Explanations

[Note]

Note

Inspect meson_options.txt for a full list of options.

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

-D cairo=disabled: This switch forces this package to not link against Cairo for the lib32 build as it will mistakenly believe that lib32-Cairo is installed if the 64-bit version is installed.

-D graphite2=disabled: This switch disables Graphite2 support, which isn't in GLFS.

-D tests=disabled: This switch disables building tests.

Short Descriptions

hb-info

is used for gathering information about fonts installed on the system

hb-ot-shape-closure

gives the set of characters contained in a string, represented as single characters and/or single character names. Example: hb-ot-shape-closure /usr/share/fonts/dejavu/DejaVuSans.ttf "Hello World."

hb-shape

is used for the conversion of text strings into positioned glyphs

hb-subset

is used to create subsets of fonts, and display text using them

hb-view

displays a graphical view of a string shape using a particular font as a set of glyphs. The output format is automatically defined by the file extension, the supported ones being ansi/png/svg/pdf/ps/eps. For example: hb-view --output-file=hello.png /usr/share/fonts/dejavu/DejaVuSans.ttf "Hello World."

libharfbuzz.so

is the HarfBuzz text shaping library

libharfbuzz-gobject.so

provides GObject integration for the HarfBuzz text shaping library

libharfbuzz-icu.so

provides ICU integration for the HarfBuzz text shaping library

libharfbuzz-subset.so

provides API functions for performing subsetting operations on font files
