3.1 Interdependency with HarfBuzz
|
||||
.................................
|
||||
|
||||
Note that there is a chicken-and-egg problem currently since the
|
||||
HarfBuzz library (used by the auto-hinter to improve support of
|
||||
OpenType fonts) depends on FreeType, which can be solved as
|
||||
follows in case HarfBuzz is not yet installed on your system.
|
||||
|
||||
1. Call FreeType's configure script with option
|
||||
`--without-harfbuzz', then compile and install FreeType.
|
||||
|
||||
2. Compile and install HarfBuzz.
|
||||
|
||||
3. Call FreeType's configure script without option
|
||||
`--without-harfbuzz', then compile and install FreeType again.
