As a special service "SfR Fresh" has tried to format the requested source page into HTML format using source code syntax highlighting with prefixed line numbers. Alternatively you can here view or download the uninterpreted source code file. That can be also achieved for any archive member file by clicking within an archive contents listing on the first character of the file(path) respectively on the according byte size field. 
    1 This  file describes various  problems that  have been  encountered in
    2 compiling,  installing  and   running  FreeType  2.   Suggestions  for
    3 additions or other improvements to this file are welcome.

    7 Running Problems
    8 ================
    9 
   10 
   11 * Some Type 1, Multiple Masters, and CID-keyed PostScript fonts aren't
   12   handled correctly.

   15 
   16 Of course,  there might be  bugs in FreeType,  but some fonts based on
   17 the  PostScript  format can't  behandled indeed.  The  reason  is that
   18 FreeType  doesn't contain a full  PostScript  interpreter  but applies
   19 pattern matching instead.  In case a font doesn't follow the  standard
   20 structure of the given font format, FreeType fails.  A typical example
   21 is Adobe's `Optima'  font family which  contains extra code  to switch
   22 between low and high resolution versions of the glyphs.
   23 
   24 It might be  possible to patch  FreeType in  some situations,  though.
   25 Please report failing fonts so that we investigate the problem and set
   26 up a list of such problematic fonts.

   31 Compilation Problems
   32 ====================
   33 
   34 
   35 * I get an `internal compilation error' (ICE) while compiling FreeType
   36   2.2.1 with Intel C++.
   37 
   38   This has been reported for the following compiler version:
   39 
   40     Intel(R) C++ Compiler for 32-bit applications,
   41       Version 9.0 Build 20050430Z Package ID: W_CC_P_9.0.019
   42 
   43 -----
   44 
   45 The best solution is to update the compiler to version
   46 
   47   Intel(R) C++ Compiler for 32-bit applications,
   48     Version 9.1 Build 20060323Z Package ID: W_CC_P_9.1.022
   49 
   50 or newer.  If this isn't feasible, apply the following patch.
