| 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. |
