SPECIAL NOTE FOR UNIX USERS
|
|
===========================
|
|
|
|
If you are installing this release of FreeType on a system that
|
|
already uses release 2.0.5 (or even an older version), you have to
|
|
perform a few special steps to ensure that everything goes well.
|
|
|
|
|
|
I. Enable the TrueType bytecode hinter if you need it
|
|
-----------------------------------------------------
|
|
|
|
See the instructions in the file "TRUETYPE" of this directory.
|
|
|
|
Note that FreeType supports TrueType fonts without the bytecode
|
|
interpreter through its auto-hinter, which now generate relatively good
|
|
results with most fonts.
|
|
|
|
|
|
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" (or what you think is adequate for your installation).
|
|
|
|
|
|
|
|
III. Ensure that you are using GNU Make
|
|
---------------------------------------
|
|
|
|
The FreeType build system _exclusively_ works with GNU Make. You
|
|
will not be able to compile the library with the instructions
|
|
below using any other alternative (including BSD Make).
|
|
|
|
Trying to compile the library with a different Make tool will
|
|
print a message like:
|
|
|
|
Sorry, GNU make is required to build FreeType2.
|
|
|
|
and the build process will be aborted. If this happens, install
|
|
GNU Make on your system, and use the GNUMAKE environment variable
|
|
to name it.
|
|
|
|
|
|
|
|
IV. Build and install the library
|
|
---------------------------------
|
|
|
|
The following should work on all Unix systems where the `make'
|
|
command invokes GNU Make:
|
|
|
|
./configure --prefix=<yourprefix>
|
|
make
|
|
make install (as root)
|
|
|
|
where "<yourprefix>" must be replaced by the prefix returned by
|
|
the "freetype-config" command.
|
|
|
|
When using a different command to invoke GNU Make, use the GNUMAKE
|
|
variable. For example, if `gmake' is the command to use on your
|
|
system, do something like:
|
|
|
|
GNUMAKE=gmake ./configure --prefix=<yourprefix>
|
|
gmake
|
|
gmake install (as root)
|
|
|
|
If this still doesn't work, read the detailed compilation
|
|
procedure available in the file "docs/BUILD" for troubleshooting.
|
|
|
|
|
|
V. Take care of XFree86 version 4
|
|
---------------------------------
|
|
|
|
Certain recent Linux distributions will install _several_ versions
|
|
of FreeType on your system. For example, on a fresh Mandrake 8.1
|
|
system, you can 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 this situation:
|
|
|
|
- Install the library _twice_, in "/usr" and in "/usr/X11R6"
|
|
(you have 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 problem, so please
|
|
contact either the XFree86 development team or your Linux
|
|
distributor to help clear this issue in case the information given
|
|
here doesn't help.
