By continuing to use, modify, or distribute this file you +indicate that you have read the license and understand and accept it +fully. + + +The makefile.os4 is for the AmigaOS4 SDK. To use it, type +"make -f makefile.os4", it produces a link library libft2_ppc.a. + +The makefile is for ppc-morphos-gcc-2.95.3-bin.tgz (gcc 2.95.3 hosted on +68k-Amiga producing MorphOS-PPC-binaries from http://www.morphos.de). +To use it, type "make assign", then "make"; it produces a link library +libft2_ppc.a. + +The smakefile is a makefile for Amiga SAS/C 6.58 (no longer available, +latest sold version was 6.50, updates can be found in Aminet). It is +based on the version found in the sourcecode of ttf.library 0.83b for +FreeType 1.3.1 from Richard Griffith (ragriffi@sprynet.com, +http://ragriffi.home.sprynet.com). + +You will also need the latest include files and amiga.lib from the +Amiga web site (https://os.amigaworld.de/download.php?id=3) for +AmigaOS 3.9; the generated code should work under AmigaOS 2.04 and up. + +To use it, call "smake assign" and then "smake" from the builds/amiga +directory. The results are: + +- A link library "ft2_680x0.lib" (where x depends on the setting of + the CPU entry in the smakefile) containing all FreeType2 parts + except of the init code, debugging code, and the system interface + code. + +- ftsystem.o, an object module containing the standard version of the + system interface code which uses fopen() fclose() fread() fseek() + ftell() malloc() realloc() and free() from lib:sc.lib (not pure). + +- ftsystempure.o, an object module containing the pure version of the + system interface code which uses Open() Close() Read() Seek() + ExamineFH() AsmAllocPooled() AsmFreePooled() etc. This version can + be used in both normal programs and in Amiga run-time shared system + librarys (can be linked with lib:libinit.o, no copying of DATA and + BSS hunks for each OpenLibrary() necessary). Source code is in + src/base/ftsystem.c. + +- ftdebug.o, an object module containing the standard version of the + debugging code which uses vprintf() and exit() (not pure). + Debugging can be turned on in FT:include/freetype/config/ftoption.h + and with FT_SetTraceLevel(). + +- ftdebugpure.o, an object module containing the pure version of the + debugging code which uses KVPrintf() from lib:debug.lib and no + exit(). For debugging of Amiga run-time shared system libraries. + Source code is in src/base/ftdebug.c. + +- NO ftinit.o. Because linking with a link library should result in + linking only the needed object modules in it, but standard + ftsystem.o would force ALL FreeType2 modules to be linked to your + program, I decided to use a different scheme: You must #include + FT:src/base/ftinit.c in your sourcecode and specify with #define + statements which modules you need. See + include/freetype/config/ftmodule.h. + + +To use in your own programs: + +- Insert the #define and #include statements from top of + include/freetype/config/ftmodule.h in your source code and + uncomment the #define statements for the FreeType2 modules you need. + +- You can use either PARAMETERS=REGISTER or PARAMETERS=STACK for + calling the FreeType2 functions, because the link library and the + object files are compiled with PARAMETERS=BOTH. + +- "smake assign" (assign "FT:" to the FreeType2 main directory). + +- Compile your program. + +- Link with either ftsystem.o or ftsystempure.o, if debugging enabled + with either ftdebug.o or (ftdebugpure.o and lib:debug.lib), and with + ft2_680x0.lib as link library. + + +To adapt to other compilers: + +- The standard ANSI C maximum length of 31 significant characters in + identifiers is not enough for FreeType2. Check if your compiler has + a minimum length of 40 significant characters or can be switched to + it. "idlen=40" is the option for SAS/C. Setting #define + HAVE_LIMIT_ON_IDENTS in an include file may also work (not tested). + +- Make sure that the include directory in builds/amiga is searched + before the normal FreeType2 include directory, so you are able to + replace problematic include files with your own version (same may be + useful for the src directory). + +- An example of how to replace/workaround a problematic include file + is include/freetype/config/ftconfig.h; it changes a #define that + would prevent SAS/C from generating XDEF's where it should do that and + then includes the standard FreeType2 include file. + +Local Variables: +coding: latin-1 +End: |
