| 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. |
