Instructions on how to build FreeType with your own build tool
==============================================================
See the file `CUSTOMIZE' to learn how to customize FreeType to
specific environments.
I. Standard procedure
---------------------
* If you use macro names for FreeType header files (while mandatory
in earlier versions, this is now optional since FreeType version
2.6.1) it is necessary to disable pre-compiled headers. This is
very important for Visual C++, because lines like
#include FT_FREETYPE_H
are not correctly supported by this compiler while being ISO C
compliant!
* You need to add the directory `include' to your include path when
compiling the library.
* FreeType 2 is made of several components; each of them is located
in a subdirectory of `freetype/src'. For example,
`freetype/src/truetype/' contains the TrueType font driver.
* DO NOT COMPILE ALL C FILES! Rather, compile the following ones.
-- base components (required)
src/base/ftsystem.c
src/base/ftinit.c
src/base/ftdebug.c
src/base/ftbase.c
src/base/ftbbox.c -- recommended, see <ftbbox.h>
src/base/ftglyph.c -- recommended, see <ftglyph.h>
src/base/ftbdf.c -- optional, see <ftbdf.h>
src/base/ftbitmap.c -- optional, see <ftbitmap.h>
src/base/ftcid.c -- optional, see <ftcid.h>
src/base/ftfstype.c -- optional
src/base/ftgasp.c -- optional, see <ftgasp.h>
src/base/ftgxval.c -- optional, see <ftgxval.h>
src/base/ftmm.c -- optional, see <ftmm.h>
src/base/ftotval.c -- optional, see <ftotval.h>
src/base/ftpatent.c -- optional
src/base/ftpfr.c -- optional, see <ftpfr.h>
src/base/ftstroke.c -- optional, see <ftstroke.h>
src/base/ftsynth.c -- optional, see <ftsynth.h>
src/base/fttype1.c -- optional, see <t1tables.h>
src/base/ftwinfnt.c -- optional, see <ftwinfnt.h>
src/base/ftmac.c -- only on the Macintosh
-- font drivers (optional; at least one is needed)
src/bdf/bdf.c -- BDF font driver
src/cff/cff.c -- CFF/OpenType font driver
src/cid/type1cid.c -- Type 1 CID-keyed font driver
src/pcf/pcf.c -- PCF font driver
src/pfr/pfr.c -- PFR/TrueDoc font driver
src/sfnt/sfnt.c -- SFNT files support
(TrueType & OpenType)
src/truetype/truetype.c -- TrueType font driver
src/type1/type1.c -- Type 1 font driver
src/type42/type42.c -- Type 42 font driver
src/winfonts/winfnt.c -- Windows FONT / FNT font driver
-- rasterizers (optional; at least one is needed for vector
formats)
src/raster/raster.c -- monochrome rasterizer
src/sdf/sdf.c -- Signed Distance Field driver
src/smooth/smooth.c -- anti-aliasing rasterizer
-- auxiliary modules (optional)
src/autofit/autofit.c -- auto hinting module
src/cache/ftcache.c -- cache sub-system (in beta)
src/gzip/ftgzip.c -- support for compressed fonts (.gz)
src/lzw/ftlzw.c -- support for compressed fonts (.Z)
src/bzip2/ftbzip2.c -- support for compressed fonts (.bz2)
src/gxvalid/gxvalid.c -- TrueTypeGX/AAT table validation
src/otvalid/otvalid.c -- OpenType table validation
src/psaux/psaux.c -- PostScript Type 1 parsing
src/pshinter/pshinter.c -- PS hinting module
src/psnames/psnames.c -- PostScript glyph names support
Notes:
`ftcache.c' needs `ftglyph.c'
`ftfstype.c' needs `fttype1.c'
`ftglyph.c' needs `ftbitmap.c'
`ftstroke.c' needs `ftglyph.c'
`ftsynth.c' needs `ftbitmap.c'
`cff.c' needs `sfnt.c', `pshinter.c', and `psnames.c'
`truetype.c' needs `sfnt.c' and `psnames.c'
`type1.c' needs `psaux.c' `pshinter.c', and `psnames.c'
`type1cid.c' needs `psaux.c', `pshinter.c', and `psnames.c'
`type42.c' needs `truetype.c'
Please consult the central `include/freetype/config/ftoption.h'
configuration file for details on additional libraries necessary
for some optional features.
Read the file `CUSTOMIZE' in case you want to compile only a subset
of the drivers, renderers, and optional modules; a detailed
description of the various base extension is given in the top-level
file `modules.cfg'.
You are done. In case of problems, see the archives of the FreeType
development mailing list.
II. Support for flat-directory compilation
------------------------------------------
It is possible to put all FreeType 2 source files into a single
directory, with the *exception* of the `include' hierarchy.
1. Copy all files in current directory
cp freetype/src/base/*.[hc] .
cp freetype/src/raster1/*.[hc] .
cp freetype/src/smooth/*.[hc] .
etc.
2. Compile sources
cc -c -Iinclude -DFT2_BUILD_LIBRARY ftsystem.c
cc -c -Iinclude -DFT2_BUILD_LIBRARY ftinit.c
cc -c -Iinclude -DFT2_BUILD_LIBRARY ftdebug.c
cc -c -Iinclude -DFT2_BUILD_LIBRARY ftbase.c
etc.
You don't need to define the FT_FLAT_COMPILATION macro (as this
was required in previous releases of FreeType 2).
