- 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.
