   14 The makefile.os4 is for the AmigaOS4 SDK.  To use it, type
   15 "make -f makefile.os4", it produces a link library libft2_ppc.a.
   16 
   17 The makefile is for ppc-morphos-gcc-2.95.3-bin.tgz (gcc 2.95.3 hosted on
   18 68k-Amiga producing MorphOS-PPC-binaries from http://www.morphos.de).
   19 To use it, type "make assign", then "make"; it produces a link library
   20 libft2_ppc.a.
   21 
   22 The smakefile is a makefile for Amiga SAS/C 6.58 (no longer available,
   23 latest sold version was 6.50, updates can be found in Aminet).  It is
   24 based on the version found in the sourcecode of ttf.library 0.83b for
   25 FreeType 1.3.1 from Richard Griffith (ragriffi@sprynet.com,
   26 http://ragriffi.home.sprynet.com).
   27 
   28 You will also need the latest include files and amiga.lib from the
   29 Amiga web site (http://www.amiga.com/3.9/download/NDK3.9.lha) for
   30 AmigaOS 3.9; the generated code should work under AmigaOS 2.04 and up.
   31 
   32 To use it, call "smake assign" and then "smake" from the builds/amiga
   33 directory.  The results are:
   34 
   35 - A link library "ft2_680x0.lib" (where x depends on the setting of
   36   the CPU entry in the smakefile) containing all FreeType2 parts
   37   except of the init code, debugging code, and the system interface
   38   code.
   39 
   40 - ftsystem.o, an object module containing the standard version of the
   41   system interface code which uses fopen() fclose() fread() fseek()
   42   ftell() malloc() realloc() and free() from lib:sc.lib (not pure).
   43 
   44 - ftsystempure.o, an object module containing the pure version of the
   45   system interface code which uses Open() Close() Read() Seek()
   46   ExamineFH() AsmAllocPooled() AsmFreePooled() etc.  This version can
   47   be used in both normal programs and in Amiga run-time shared system
   48   librarys (can be linked with lib:libinit.o, no copying of DATA and
   49   BSS hunks for each OpenLibrary() necessary).  Source code is in
   50   src/base/ftsystem.c.
   51 
   52 - ftdebug.o, an object module containing the standard version of the
   53   debugging code which uses vprintf() and exit() (not pure).
   54   Debugging can be turned on in FT:include/freetype/config/ftoption.h
   55   and with FT_SetTraceLevel().
   56 
   57 - ftdebugpure.o, an object module containing the pure version of the
   58   debugging code which uses KVPrintf() from lib:debug.lib and no
   59   exit().  For debugging of Amiga run-time shared system libraries.
   60   Source code is in src/base/ftdebug.c.
   61 
   62 - NO ftinit.o.  Because linking with a link library should result in
   63   linking only the needed object modules in it, but standard
   64   ftsystem.o would force ALL FreeType2 modules to be linked to your
   65   program, I decided to use a different scheme: You must #include
   66   FT:src/base/ftinit.c in your sourcecode and specify with #define
   67   statements which modules you need.  See
   68   include/freetype/config/ftmodule.h.
   69 
   70 
   71 To use in your own programs:
   72 
   73 - Insert the #define and #include statements from top of
   74   include/freetype/config/ftmodule.h in your source code and uncomment
   75   the #define statements for the FreeType2 modules you need.
   76 
   77 - You can use either PARAMETERS=REGISTER or PARAMETERS=STACK for
   78   calling the FreeType2 functions, because the link library and the
   79   object files are compiled with PARAMETERS=BOTH.
   80 
   81 - "smake assign" (assign "FT:" to the FreeType2 main directory).
   82 
   83 - Compile your program.
   84 
   85 - Link with either ftsystem.o or ftsystempure.o, if debugging enabled
   86   with either ftdebug.o or (ftdebugpure.o and lib:debug.lib), and with
   87   ft2_680x0.lib as link library.
   88 
   89 
   90 To adapt to other compilers:
   91 
   92 - The standard ANSI C maximum length of 31 significant characters in
   93   identifiers is not enough for FreeType2.  Check if your compiler has
   94   a minimum length of 40 significant characters or can be switched to
   95   it.  "idlen=40" is the option for SAS/C.  Setting #define
   96   HAVE_LIMIT_ON_IDENTS in an include file may also work (not tested).
   97 
   98 - Make sure that the include directory in builds/amiga is searched
   99   before the normal FreeType2 include directory, so you are able to
  100   replace problematic include files with your own version (same may be
  101   useful for the src directory).
  102 
  103 - An example of how to replace/workaround a problematic include file
  104   is include/config/ftconfig.h; it changes a #define that would
  105   prevent SAS/C from generating XDEF's where it should do that and
  106   then includes the standard FreeType2 include file.
