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. | |
