Package Information

HarfBuzz Dependencies

Recommended

gobject-introspection-1.74.0 (required if building GNOME), GLib-2.74.5 (required for Pango), Graphite2-1.3.14 (required for building texlive-20220321 or LibreOffice-7.5.0.3 with system harfbuzz), ICU-72.1, and FreeType-2.13.0 (after HarfBuzz-7.0.0 is installed, reinstall FreeType-2.13.0)

Optional

Cairo-1.17.6 (circular: build cairo and all its recommended dependencies, including harfbuzz, first, then rebuild harfbuzz if the cairo backend is needed), git-2.39.2, GTK-Doc-1.33.2, FontTools (Python 3 module, for the test suite), and ragel

Installation of HarfBuzz

Install HarfBuzz by running the following commands: 

mkdir build &&
cd    build &&

meson --prefix=/usr        \
      --buildtype=release  \
      -Dgraphite2=enabled  &&
ninja

To test the results, issue: ninja test.

Now, as the root user: 

ninja install

Command Explanations

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

-Dgraphite2=enabled: This switch enables Graphite2 support, which is required for building texlive-20220321 or LibreOffice-7.5.0.3 with system harfbuzz.

-Ddocs=disabled: If GTK-Doc-1.33.2 is installed, the documentation is built and installed. This switch prevents that.

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."
