  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.

  5. Running Problems
  6. ================
  7. * Some Type 1, Multiple Masters, and CID-keyed PostScript fonts aren't
  8. handled correctly.
  9. -----
  10. Of course, there might be bugs in FreeType, but some fonts based on
  11. the PostScript format can't behandled indeed. The reason is that
  12. FreeType doesn't contain a full PostScript interpreter but applies
  13. pattern matching instead. In case a font doesn't follow the standard
  14. structure of the given font format, FreeType fails. A typical example
  15. is Adobe's `Optima' font family which contains extra code to switch
  16. between low and high resolution versions of the glyphs.
  17. It might be possible to patch FreeType in some situations, though.
  18. Please report failing fonts so that we investigate the problem and set
  19. up a list of such problematic fonts.

  21. Compilation Problems
  22. ====================
  23. * I get an `internal compilation error' (ICE) while compiling FreeType
  24. 2.2.1 with Intel C++.
  25. This has been reported for the following compiler version:
  26. Intel(R) C++ Compiler for 32-bit applications,
  27. Version 9.0 Build 20050430Z Package ID: W_CC_P_9.0.019
  28. -----
  29. The best solution is to update the compiler to version
  30. Intel(R) C++ Compiler for 32-bit applications,
  31. Version 9.1 Build 20060323Z Package ID: W_CC_P_9.1.022
  32. or newer. If this isn't feasible, apply the following patch.
