There are several ways to build the FreeType library, depending on
|
|
your system and the level of customization you need. Here is a short
|
|
overview of the documentation available:
|
|
|
|
|
|
I. Prerequisites and dependencies
|
|
=================================
|
|
|
|
FreeType is a low level C library that only depends on the standard
|
|
C library with very few platform-dependent optimizations utilized at
|
|
build time. Any C99-compliant compiler should be able to compile
|
|
FreeType. System libraries, such as zlib, Gzip, bzip2, Brotli,
|
|
and libpng, might be used to handle compressed fonts or decode
|
|
embedded PNG glyphs.
|
|
|
|
FreeType auto-configuration scripts should be able to detect the
|
|
prerequisites if the necessary headers are available at the default
|
|
locations. Otherwise, modify `include/freetype/config/ftoption.h`
|
|
to control how the FreeType library gets built. Normally, you don't
|
|
need to change anything.
|
|
|
|
Applications have very limited control over FreeType's behaviour at
|
|
run-time; look at the documentation of function `FT_Property_Set`.
|
|
|
|
|
|
II. Normal installation and upgrades
|
|
====================================
|
|
|
|
1. Unix and Unix-like systems
|
|
|
|
This also includes MacOS, Cygwin, MinGW + MSYS, Mingw-w64 + MSYS2,
|
|
and possibly other, similar environments.
|
|
|
|
Please read `INSTALL.UNIX` to install or upgrade FreeType 2 on a
|
|
Unix system. Note that you *need* GNU Make for automatic
|
|
compilation, since other make tools won't work (this includes BSD
|
|
Make).
|
|
|
|
GNU Make VERSION 3.81 OR NEWER IS NEEDED!
|
|
|
|
|
|
2. Other systems using GNU Make
|
|
|
|
On some non-Unix platforms, it is possible to build the library
|
|
using only the GNU Make utility. Note that *NO OTHER MAKE TOOL
|
|
WILL WORK*[1]! This methods supports several compilers on
|
|
Windows, OS/2, and BeOS, including MinGW* (without MSYS*), Visual
|
|
C++, Borland C++, and more.
|
|
|
|
Instructions are provided in the file `INSTALL.GNU`.
|
|
|
|
|
|
3. Other build tools and platforms.
|
|
|
|
A few other tools can be used to build FreeType. You can find
|
|
the corresponding instruction files in the FreeType root folder
|
|
or the builds/ sub-folder.
|
|
|
|
CMake :: see `CMakeLists.txt` for more information
|
|
Meson :: see `meson.build` for more information
|
|
MSBuild :: see `builds/windows/vc2010/freetype.vcxproj`
|
|
MMS :: see `vms_make.com` and `docs/INSTALL.VMS`
|
|
|
|
|
|
4. With an IDE Project File (e.g., for Visual Studio or CodeWarrior)
|
|
|
|
We provide a small number of 'project files' for various IDEs to
|
|
automatically build the library as well. Note that these files
|
|
are not actively supported by FreeType developers, they can break
|
|
or become obsolete.
|
|
|
|
To find them, have a look at the content of the `builds/<system>`
|
|
directory, where <system> stands for your OS or environment.
|
|
|
|
|
|
5. From you own IDE, or own Makefiles
|
|
|
|
If you want to create your own project file, follow the
|
|
instructions given in the `INSTALL.ANY` document of this
|
|
directory.
|
|
|
|
|
|
III. Custom builds of the library
|
|
=================================
|
|
|
|
Customizing the compilation of FreeType is easy, and allows you to
|
|
select only the components of the font engine that you really need.
|
|
For more details read the file `CUSTOMIZE`.
|
|
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
[1] make++, a make tool written in Perl, has sufficient support of GNU
|
|
make extensions to build FreeType. See
|
|
|
|
https://makepp.sourceforge.net
|
|
|
|
for more information; you need version 2.0 or newer, and you must
|
|
pass option `--norc-substitution`.
