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. |
|
|
|
|
|
1. 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 generates relatively |
|
good results with most fonts. |
|
|
|
|
|
2. Determine the correct installation path |
|
------------------------------------------ |
|
|
|
By default, the configure script 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 |
|
(e.g., "/usr" or "/usr/local"). To avoid problems of parallel |
|
FreeType versions, use this path for the --prefix option of the |
|
configure script. |
|
|
|
Otherwise, simply use "/usr" (or whatever you think is adequate for |
|
your installation). |
|
|
|
|
|
3. Ensure that you are using GNU Make |
|
------------------------------------- |
|
|
|
The FreeType build system _exclusively_ works with GNU Make (as an |
|
exception you can use make++ which emulates GNU Make sufficiently; |
|
see http://makepp.sourceforge.net). 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. |
|
|
|
|
|
4. 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) |
|
|
|
|
|
5. 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 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 would 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. |
