Installation of HarfBuzz

Install HarfBuzz by running the following commands: 

mkdir build &&
cd    build &&

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

ninja

To test the results, issue: ninja test.

Now, as the root user: 

ninja install

32-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 graphite2=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

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

-Dgraphite2=disabled: This switch disables Graphite2 support, which isn't in GLFS.

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."
