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 installs 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 prints a + message like: + + Sorry, GNU make is required to build FreeType2. + + and the build process is 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 Linux distributions 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 do 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. + +------------------------------------------------------------------------ + +Copyright 2003, 2005 by +David Turner, Robert Wilhelm, and Werner Lemberg. + +This file is part of the FreeType project, and may only be used, +modified, and distributed under the terms of the FreeType project +license, LICENSE.TXT.
