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 ([email protected], http://ragriffi.home.sprynet.com). You will also need the latest include files and amiga.lib from the Amiga Developer CD V2.1 (or newer, I hope...) for AmigaOS 3.5, the generated code should work under AmigaOS 2.04 (V37) 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. Since 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, since 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 adopt 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/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.
