Overview of changes leading to 0.9.18
Tuesday, May 28, 2013
=====================================
New build system:
- All unneeded code is all disabled by default,
- Uniscribe and CoreText shapers can be enabled with their --with options,
- icu_le and old shapers cannot be enabled for now,
- glib, freetype, and cairo will be detected automatically.
They can be force on/off'ed with their --with options,
- icu and graphite2 are default off, can be enabled with their --with
options,
Moreover, ICU support is now build into a separate library:
libharfbuzz-icu.so, and a new harfbuzz-icu.pc is shipped for it.
Distros can enable ICU now without every application on earth
getting linked to via libharfbuzz.so.
For distros I recommend that they make sure they are building --with-glib
--with-freetype --with-cairo, --with-icu, and optionally --with-graphite2;
And package harfbuzz and harfbuzz-icu separately.
