SPECIAL NOTE FOR UNIX USERS:
|
|
============================
|
|
|
|
If you're installing this release of FreeType on a system that
|
|
already uses release 2.0.5 (or even an older version), you'll
|
|
need to perform a few special steps to ensure that everything
|
|
goes well:
|
|
|
|
|
|
I. Enable the TrueType bytecode hinter if you need it:
|
|
------------------------------------------------------
|
|
|
|
The TrueType bytecode interpreter is disabled in all
|
|
public releases of the FreeType packages for patents
|
|
reasons (see www.freetype.org/patents.html for more
|
|
details).
|
|
|
|
However, many Linux distributions do enable the
|
|
interpreter in the FreeType packages (DEB/RPM/etc..) they
|
|
produce for their platforms. If you're using TrueType fonts
|
|
on your system, you'll most probably want to enable it
|
|
manually by doing the following:
|
|
|
|
- open the file "include/freetype/config/ftoption.h"
|
|
|
|
- locate a line that says:
|
|
|
|
#undef TT_CONFIG_OPTION_BYTECODE_ITNERPRETER
|
|
|
|
- change it to:
|
|
|
|
#define TT_CONFIG_OPTION_BYTECODE_INTERPRETER
|
|
|
|
of course, this must be done _before_ compiling the
|
|
library
|
|
|
|
|
|
II. Determine the correct installation path:
|
|
--------------------------------------------
|
|
|
|
By default, the source package will install the library
|
|
in "/usr/local". However, many Unix distributions now
|
|
install the library in "/usr", since FreeType is becoming
|
|
a critical system component
|
|
|
|
|
|
If FreeType is already installed on your system, type
|
|
|
|
freetype-config --prefix
|
|
|
|
on the command line. This should return the installation
|
|
path to use below (e.g. "/usr" or "/usr/local"). Otherwise,
|
|
simply use "/usr"
|
|
|
|
|
|
then, to build and install the library, type:
|
|
|
|
make setup unix CFG="--prefix=<yourprefix>"
|
|
make
|
|
make install (as root)
|
|
|
|
where "<yourprefix>" must be replaced by the prefix returned
|
|
by the "freetype-config" command.
|
|
|
|
|
|
III. Take care of XFree86 4:
|
|
----------------------------
|
|
|
|
Certain recent Linux distributions will install _several_
|
|
versions of FreeType on your system.. For example, on a
|
|
fresh Mandrake 8.1 system, you'll find the following files:
|
|
|
|
/usr/lib/libfreetype.so which links to
|
|
/usr/lib/libfreetype.6.1.0.so
|
|
|
|
and:
|
|
|
|
/usr/X11R6/lib/libfreetype.so which links to
|
|
/usr/X11R6/lib/libfreetype.6.0.so
|
|
|
|
note that these files correspond to two distinct versions of
|
|
the library ! It seems that this surprising issue is due to
|
|
the install scripts of recent XFree86 servers (from 4.1.0)
|
|
which irremediably install their own (dated) version of
|
|
the library in "/usr/X11R6/lib"
|
|
|
|
In certain _rare_ cases, you may experience minor problems if
|
|
you install this release of the library in "/usr" only, namely,
|
|
that certain applications will not benefit from the bug fixes
|
|
and rendering improvements you'd expect..
|
|
|
|
There are two good ways to deal with such nasty systems:
|
|
|
|
- install the library _twice_, in "/usr" and in "/usr/X11R6"
|
|
(you'll need to do that each time you install a new
|
|
FreeType release though)
|
|
|
|
- change the link in /usr/X11R6/lib/libfreetype.so to point
|
|
to /usr/lib/libfreetype.so, and get rid of
|
|
/usr/X11R6/lib/libfreetype.6.0.so
|
|
|
|
|
|
The FreeType Team is not responsible for this mess, so please contact
|
|
either the XFree86 development team or your Linux distributor to help
|
|
clear this issue.., or if the above information doesn't help..
