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. Normal installation and upgrades
===================================
0. Modify `include/freetype/config/ftoption.h', if necessary, to
control how the FreeType library gets built. Normally, you don't
need to change anything.
Applications can't control FreeType's behaviour at build time.
To make applications control (some of) FreeType's behaviour at
run-time, look at the documentation of function
`FT_Property_Set'.
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!
[For `cmake' see below.]
2. On VMS with the `mms' build tool
See `INSTALL.VMS' for installation instructions on this platform.
3. 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'.
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 supported and only sporadically maintained by FreeType
developers, so don't expect them to work in each release.
To find them, have a look at the content of the `builds/<system>'
directory, where <system> stands for your OS or environment.
5. Using cmake
See the top-level `CMakeLists.txt' file for more information.
6. 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.
II. 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'.
