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/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. |
