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 (http://www.amiga.com/3.9/download/NDK3.9.lha) 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. | |
