Beyond Linux® From Scratch - Version 7.9

Chapter 10. Graphics and Font Libraries

Graphite2-1.3.5

Introduction to Graphite2

Graphite2 is a rendering engine for graphite fonts. These are TrueType fonts with additional tables containing smart rendering information and were originally developed to support complex non-Roman writing systems. They may contain rules for e.g. ligatures, glyph substitution, kerning, justification - this can make them useful even on text written in Roman writing systems such as English. Note that firefox provides an internal copy of the graphite engine and cannot use a system version, but it too should benefit from the availability of graphite fonts.

This package is known to build and work properly using an LFS-7.9 platform.

Package Information

Graphite2 Dependencies

Required

CMake-3.4.3

Optional

FreeType-2.6.3, Python-2.7.11, and silgraphite to build the comparerender test and benchmarking tool, and if that is present, Harfbuzz-1.1.3 to add more functionality to it (this is a circular dependency, you would need to first build graphite2 without harfbuzz).

To build the documentation: AsciiDoc, Doxygen-1.8.11, texlive-20150521 (or install-tl-unx), and dblatex (for PDF docs)

To execute the test suite you will need FontTools (Python 2 module), otherwise, the "cmp" tests fail.

Optional (at runtime)

You will need at least one suitable graphite font for the package to be useful.

Installation of Graphite2

Some tests fail if FontTools (Python 2 module) is not installed. These tests can be removed with: 

sed -i '/cmptest/d' tests/CMakeLists.txt

Install Graphite2 by running the following commands: 

mkdir build &&
cd    build &&

cmake -G "Unix Makefiles"         \
      -DCMAKE_INSTALL_PREFIX=/usr \
      -Wno-dev .. &&

make

If you wish to build the documentation, issue: 

make docs

To test the results, issue: make test.

Now, as the root user: 

make install

If you built the documentation, install, as the root user: 

install -v -d -m755 /usr/share/doc/graphite2-1.3.5/api &&
cp      -v -r -f    doc/doxygen/{html,latex/refman.pdf} \
                    /usr/share/doc/graphite2-1.3.5/api &&
cp      -v -r -f    doc/{GTF,manual}.html \
                    /usr/share/doc/graphite2-1.3.5

Command Explanations

-DCMAKE_VERBOSE_MAKEFILE=ON: This switch turns on build verbose mode.
