This document contains instructions how to build the FreeType library
|
|
on non-Unix systems with the help of GNU Make. Note that if you are
|
|
running Cygwin or MinGW/MSYS in Windows, you should follow the
|
|
instructions in the file `INSTALL.UNIX' instead.
|
|
|
|
|
|
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.
|
|
|
|
1. Install GNU Make
|
|
-------------------
|
|
|
|
Because GNU Make is the only Make tool supported to compile
|
|
FreeType 2, you should install it on your machine.
|
|
|
|
The FreeType 2 build system relies on many features special to GNU
|
|
Make.
|
|
|
|
NEARLY ALL OTHER MAKE TOOLS FAIL, INCLUDING `BSD MAKE', SO REALLY
|
|
INSTALL A RECENT VERSION OF GNU MAKE ON YOUR SYSTEM!
|
|
|
|
Note that make++, a make tool written in Perl, supports enough
|
|
features of GNU make to compile FreeType. See
|
|
|
|
http://makepp.sourceforge.net
|
|
|
|
for more information; you need version 2.0 or newer, and you must
|
|
pass option `--norc-substitution'.
|
|
|
|
Make sure that you are invoking GNU Make from the command line, by
|
|
typing something like:
|
|
|
|
make -v
|
|
|
|
to display its version number.
|
|
|
|
VERSION 3.81 OR NEWER IS NEEDED!
|
|
|
|
|
|
2. Invoke `make'
|
|
----------------
|
|
|
|
Go to the root directory of FreeType 2, 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 windows
|
|
compiler gcc
|
|
configuration directory .\builds\windows
|
|
configuration rules .\builds\windows\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
|
|
or 'make refdoc' to build the API reference (the latter needs
|
|
python).
|
|
=============================================================
|
|
|
|
|
|
If the detected settings correspond to your platform and compiler,
|
|
skip to step 5. Note that if your platform is completely alien to
|
|
the build system, the detected platform will be `ansi'.
|
|
|
|
|
|
3. 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 default compiler), invoke GNU Make
|
|
with
|
|
|
|
make setup <compiler>
|
|
|
|
Examples:
|
|
|
|
to use Visual C++ on Win32, type: `make setup visualc'
|
|
to use Borland C++ on Win32, type `make setup bcc32'
|
|
to use Watcom C++ on Win32, type `make setup watcom'
|
|
to use Intel C++ on Win32, type `make setup intelc'
|
|
to use LCC-Win32 on Win32, type: `make setup lcc'
|
|
to use Watcom C++ on OS/2, type `make setup watcom'
|
|
to use VisualAge C++ on OS/2, type `make setup visualage'
|
|
|
|
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'.
|
|
|
|
If you are satisfied by the new configuration summary, skip to
|
|
step 5.
|
|
|
|
|
|
4. Configure the build system for an unknown platform/compiler
|
|
--------------------------------------------------------------
|
|
|
|
The auto-detection/setup phase of the build system copies 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, copy
|
|
manually the configuration sub-makefile to `./config.mk' and go to
|
|
step 5.
|
|
|
|
Note that this file is a sub-Makefile used to specify Make
|
|
variables for compiler and linker invocation 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'.
|
|
|
|
|
|
5. 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. [It has also generated a file called
|
|
`ftmodule.h' in the objects directory (which is normally
|
|
`<toplevel>/objs/'); please read the file `docs/CUSTOMIZE' for
|
|
customization of FreeType.]
|
|
|
|
To launch the build, simply invoke GNU Make again: The top
|
|
Makefile will detect the configuration file and run the build with
|
|
it.
|
|
|
|
|
|
Final note
|
|
|
|
The above instructions build a _statically_ linked library of the
|
|
font engine in the `objs' directory. On Windows, you can build a
|
|
DLL either with MinGW (within an MSYS shell, following the
|
|
instructions in `INSTALL.UNIX'), or you use one of the Visual C++
|
|
project files; see the subdirectories of `builds/windows'. For
|
|
everything else, you are on your own, and you might follow the
|
|
instructions in `INSTALL.ANY' to create your own Makefiles.
