This file describes various problems that have been encountered in
|
|
compiling, installing and running FreeType 2. Suggestions for
|
|
additions or other improvements to this file are welcome.

Running Problems
|
|
================
|
|
|
|
|
|
* Some Type 1, Multiple Masters, and CID-keyed PostScript fonts aren't
|
|
handled correctly.
|
|
|
|
-----
|
|
|
|
Of course, there might be bugs in FreeType, but some fonts based on
|
|
the PostScript format can't be handled indeed. The reason is that
|
|
FreeType doesn't contain a full PostScript interpreter but applies
|
|
pattern matching instead. In case a font doesn't follow the standard
|
|
structure of the given font format, FreeType fails. A typical example
|
|
is Adobe's `Optima' font family which contains extra code to switch
|
|
between low and high resolution versions of the glyphs.
|
|
|
|
It might be possible to patch FreeType in some situations, though.
|
|
Please report failing fonts so that we investigate the problem and set
|
|
up a list of such problematic fonts.
|
|
|
|
|
|
* Why do identical FreeType versions render differently on different
|
|
platforms?
|
|
|
|
-----
|
|
|
|
Different distributions compile FreeType with different options. The
|
|
developer version of a distribution's FreeType package, which is
|
|
needed to compile your program against FreeType, includes the file
|
|
ftoption.h. Compare each platform's copy of ftoption.h to find the
|
|
differences.

Compilation Problems
|
|
====================
|
|
|
|
|
|
* I get an `internal compilation error' (ICE) while compiling FreeType
|
|
2.2.1 with Intel C++.
|
|
|
|
This has been reported for the following compiler version:
|
|
|
|
Intel(R) C++ Compiler for 32-bit applications,
|
|
Version 9.0 Build 20050430Z Package ID: W_CC_P_9.0.019
|
|
|
|
-----
|
|
|
|
The best solution is to update the compiler to version
|
|
|
|
Intel(R) C++ Compiler for 32-bit applications,
|
|
Version 9.1 Build 20060323Z Package ID: W_CC_P_9.1.022
|
|
|
|
or newer. If this isn't feasible, apply the following patch.
