FreeType 2 compilation how-to
|
|
|
|
|
|
Introduction:
|
|
|
|
Welcome to this new beta of the FreeType 2 library. You'll find in this
|
|
document instructions on how to compile the library on your favorite
|
|
platform.
|
|
|
|
*** UNIX USERS : Even though the FT2 build system doesn't
|
|
************** : use the Autoconf/Automake tools, these will
|
|
************** : be introduced in the Unix-specific parts of
|
|
************** : the build in our final release..
|
|
|
|
|
|
I. QUICK COMMAND-LINE GUIDE:
|
|
----------------------------
|
|
|
|
Install GNU Make, then try the following on Unix or any system with gcc:
|
|
|
|
make // this will setup the build
|
|
make // this will build the library
|
|
|
|
On Win32+Visual C++:
|
|
|
|
make setup visualc // setup the build for VisualC++ on Win32
|
|
make // build the library
|
|
|
|
Then, go to the "demos" directory and type
|
|
|
|
make
|
|
|
|
To compile the demo programs..
|
|
|
|
If this doesn't work, read the following..
|
|
|
|
|
|
|
|
II. COMMAND-LINE COMPILATION:
|
|
-----------------------------
|
|
|
|
Note that if you do not want to compile FreeType 2 from a command line
|
|
shell, please skip to section III below (DETAILED COMPILATION)
|
|
|
|
FreeType 2 includes a powerful and flexible build system that allows you
|
|
to easily compile it on a great variety of platforms from the command
|
|
line. To do so, just follow these simple instructions:
|
|
|
|
a/ Install GNU Make:
|
|
|
|
Because GNU Make is the only Make tool supported to compile FreeType 2,
|
|
you should install it on your machine.
|
|
|
|
Because the FT2 build system relies on many important features of GNU
|
|
Make, trying to build the library with any other Make tool will *fail*.
|
|
|
|
|
|
b/ Invoke "make":
|
|
|
|
Go to the root FT2 directory, then simply invoke GNU Make from the
|
|
command line, this will launch the FreeType 2 Host Platform detection
|
|
routines. A summary will be displayed, for example, on Win32:
|
|
|
|
========================================================================
|
|
FreeType build system -- automatic system detection
|
|
|
|
The following settings are used:
|
|
|
|
platform win32
|
|
compiler gcc
|
|
configuration directory ./builds/win32
|
|
configuration rules ./builds/win32/w32-gcc.mk
|
|
|
|
If this does not correspond to your system or settings please remove
|
|
the file 'config.mk' from this directory then read the INSTALL file
|
|
for help.
|
|
|
|
Otherwise, simply type 'make' again to build the library.
|
|
=========================================================================
|
|
|
|
If the detected settings correspond to your platform and compiler,
|
|
skip to step e/. Note that if your platform is completely alien to
|
|
the build system, the detected platform will be "ansi".
|
|
|
|
|
|
c/ Configure the build system for a different compiler:
|
|
|
|
If the build system correctly detected your platform, but you want to
|
|
use a different compiler than the one specified in the summary (for
|
|
most platforms, gcc is the defaut compiler), simply invoke GNU Make
|
|
like :
|
|
|
|
make setup <compiler>
|
|
|
|
For example:
|
|
|
|
to use Visual C++ on Win32, type: "make setup visualc"
|
|
to use LCC-Win32 on Win32, type: "make setup lcc"
|
|
|
|
The <compiler> name to use is platform-dependent. The list of available
|
|
compilers for your system is available in the file
|
|
"builds/<system>/detect.mk" (note that we hope to make the list
|
|
displayed at user demand in the final release)..
|
|
|
|
If you're satisfying by the new configuration summary, skip to step e/
|
|
|
|
|
|
d/ Configure the build system for an unknown platform/compiler:
|
|
|
|
What the auto-detection/setup phase of the build system does is simply
|
|
copy a file to the current directory under the name "config.mk".
|
|
|
|
For example, on OS/2+gcc, it would simply copy "builds/os2/os2-gcc.mk"
|
|
to "./config.mk"
|
|
|
|
If for some reason your platform isn't correctly detected, simply copy
|
|
manually the configuration sub-makefile to "./config.mk" and go to
|
|
step e/.
|
|
|
|
Note that this file is a sub-Makefile used to specify Make variables
|
|
used to invoke the compiler and linker during the build, you can easily
|
|
create your own version from one of the existing configuration files,
|
|
then copy it to the current directory under the name "./config.mk".
|
|
|
|
|
|
e/ Build the library:
|
|
|
|
The auto-detection/setup phase should have copied a file in the current
|
|
directory, called "./config.mk". This file contains definitions of various
|
|
Make variables used to invoke the compiler and linker during the build.
|
|
|
|
To launch the build, simply invoke GNU Make again: the top Makefile will
|
|
detect the configuration file and run the build with it..
|
|
|
|
|
|
f/ Build the demonstration programs:
|
|
|
|
Once the library is compiled, go to "demos", then invoke GNU Make.
|
|
|
|
Note that the demonstration programs include a tiny graphics sub-system
|
|
that includes "drivers" to display Windows on Win32, X11 and OS/2. The
|
|
build system should automatically detect which driver to use based on
|
|
the current platform.
|
|
|
|
UNIX USERS TAKE NOTE: XXXXXX
|
|
|
|
When building the demos, the build system tries to detect your X11 path
|
|
by looking for the patterns "X11R5/bin", "X11R6/bin" or "X11/bin" in
|
|
your current path. If no X11 path is found, the demo programs will not
|
|
be able to display graphics and will fail. Change your current path
|
|
if you encounter this problem.
|
|
|
|
Note that the release version will use Autoconf to detect everything
|
|
on Unix, so this will not be necessary !!
|
|
|
|
|
|
II. DETAILED COMPILATION PROCEDURE:
|
|
-----------------------------------
|
|
|
|
If you don't want to compile FreeType 2 from the command-line (for example
|
|
from a graphical IDE on a Mac or Windows), you'll need to understand how the
|
|
FreeType files are organized.
|
|
|
|
FreeType 2 has a very module design, and it is made of several components.
|
|
Each component must be compiled as a stand-alone object file, even when it
|
|
is really made of several C source files. For example, the "base layer"
|
|
component is made of the following C files:
|
|
|
|
src/
|
|
base/
|
|
ftcalc.c - computations
|
|
ftobjs.c - object management
|
|
ftstream.c - stream input
|
|
ftlist.c - simple list management
|
|
ftoutln.c - simple outline processing
|
|
ftextend.c - extensions support
|
|
|
|
However, you can create a single object file by compiling the file
|
|
"src/base/ftbase.c", whose content is basically:
|
|
|
|
#include <base/ftcalc.c>
|
|
#include <base/ftobjs.c>
|
|
#include <base/ftstream.c>
|
|
#include <base/ftlist.c>
|
|
#include <base/ftoutln.c>
|
|
#include <base/ftextend.c>
|
|
|
|
Similarly, each component has a single "englobing" C file to compile it
|
|
as a stand-alone object, i.e. :
|
|
|
|
src/base/ftbase.c - the base layer, high-level interface
|
|
src/sfnt/sfnt.c - the "sfnt" module
|
|
src/psnames/psnames.c - the Postscript Names module
|
|
src/truetype/truetype.c - the TrueType font driver
|
|
src/type1/type1.c - the Type 1 font driver
|
|
|
|
|
|
To compile one component, do the following:
|
|
|
|
- add the top-level "include" directory to your compilation include path
|
|
|
|
- add the "src" directory to your compilation include path.
|
|
|
|
- compile the component "source" file (see list below), you don't need
|
|
to be in the component's directory..
|
|
|
|
For example, the following line can be used to compile the truetype driver
|
|
on Unix:
|
|
|
|
cd freetype2/
|
|
cc -c -Iinclude -Isrc src/truetype/truetype.c
|
|
|
|
Alternatively:
|
|
|
|
cd freetype2/src/truetype
|
|
cc -c -I../../include -I.. truetype.c
|
|
|
|
The complete list of files to compile for a feature-complete build of
|
|
FreeType 2 is:
|
|
|
|
src/base/ftsystem.c - system-specific memory and i/o support
|
|
src/base/ftinit.c - initialisation layer
|
|
src/base/ftdebug.c - debugging component (empty in release build)
|
|
src/base/ftbase.c - the "base layer" component
|
|
src/base/ftglyph.c - optional convenience functions
|
|
src/raster1/raster1.c - the monochrome bitmap renderer
|
|
src/smooth/smooth.c - the anti-aliased bitmap renderer
|
|
src/sfnt/sfnt.c - the "sfnt" module
|
|
src/psnames/psnames.c - the "psnames" module
|
|
src/truetype/truetype.c - the TrueType font driver
|
|
src/type1/type1.c - the Type 1 font driver (incl. Multiple Masters)
|
|
src/cid/type1cid.c - the Type 1 CID-keyed font driver
|
|
src/cff/cff.c - the OpenType/CFF/CEF font driver
|
|
src/winfonts/winfnt.c - the Windows FNT/FON font driver
|
|
|
|
All font drivers are optional. the "sfnt" and "psnames" modules are
|
|
mandatory for certain drivers.
|
|
|
|
|
|
III. Support for flat-directory compilation:
|
|
----------------------------------------
|
|
|
|
It is now possible to put all FreeType 2 source files into a single
|
|
directory, with the exception of the "include" hierarchy.
|
|
|
|
Note that you'll still need to only compile the 'wrapper' sources described
|
|
above. Define the "FT_FLAT_COMPILE" macro when compiling. Here's an
|
|
example:
|
|
|
|
1/ Copy all files in current directory:
|
|
|
|
cp freetype2/src/base/*.[hc] .
|
|
cp freetype2/src/raster1/*.[hc] .
|
|
cp freetype2/src/smooth/*.[hc] .
|
|
etc...
|
|
|
|
2/ Compile sources:
|
|
|
|
cc -c -DFT_FLAT_COMPILE -Ifreetype/include ftsystem.c
|
|
cc -c -DFT_FLAT_COMPILE -Ifreetype/include ftinit.c
|
|
cc -c -DFT_FLAT_COMPILE -Ifreetype/include ftdebug.c
|
|
cc -c -DFT_FLAT_COMPILE -Ifreetype/include ftbase.c
|
|
etc...
|
|
|
