I am close to porting AppleWin for Amiga.

while building without noixemul ( found default options in AmiDevCPP)

objects/CPU.o(.text+0x25156):objects/CPU.o: undefined reference to `___eprintf'
objects/CPU.o(.text+0x253c2):objects/CPU.o: undefined reference to `___eprintf'
objects/CPU.o(.text+0x25422):objects/CPU.o: undefined reference to `___eprintf'
objects/CPU.o(.text+0x25496):objects/CPU.o: undefined reference to `___eprintf'
objects/CPU.o(.text+0x25508):objects/CPU.o: undefined reference to `___eprintf'

$ m68k-amigaos-nm.exe ../objects/CPU.o | grep  print
         U ___eprintf

there is not a single occurance of eprint in the whole source.
any idea where it does come from?

#1) sort of compiler issue MingW

So what will be your next step?

[alkis]

try adding this
https://github.com/eblot/newlib/blob...dlib/eprintf.c
to the project

now i get a duplicate, it is already in assert.h:

$ grep  eprint usr/local/amiga/m68k-amigaos/include/assert.h
extern void __eprintf (const char *, const char *, int, const char *);
extern void __eprintf (const char *, const char *, int, const char *);
  (__eprintf ("%s:%u: failed assertion `%s'\n",         \
extern void __eprintf (); /* Defined in libgcc.a */
  (__eprintf ("%s:%u: failed assertion `%s'\n",

so i need to put an extern ... eprint in cpu.cpp or remove all _ASSERT ?

#1)
added those in cpu.cpp:
extern void __eprintf (const char *, const char *, int, const char *);
extern void __eprintf (); /* Defined in libgcc.a */

added -lgcc to linker option, all does not have an effect :/

[alkis]

have downloaded the file and added eprintf.c to the project?

or just add this to any file (just once)

void
__eprintf (format, file, line, expression)
     const char *format;
     const char *file;
     unsigned int line;
     const char *expression;
{
  (void) fiprintf (stderr, format, file, line, expression);
  abort ();
  /*NOTREACHED*/
}

i added the code in an existing src code file cpu.cpp, but __eprintf
is already defined in assert.h - got duplicate definition when compiling.

so since nothing worked, i just "//" all _ASSERT && assert lines
and now it does build

Building is one thing but does it run, can you select disk image, can it boot games, is it functional?

IIRC these asserts are sort of error checking, not relevant to the emulator code,
just testing/checking things.

and not using "-noixemul" does have a positive effect,
directory listing now does work without any fix

even choosing a dsk image does work now too.
get flooded with debug infos , ahve to look at it.

i guess the config loading issue could be fixed now too.

#1) indeed, enabled LoadConfig - does work now, does output massive debug infos, but no more crash

[xboxown]

Wait...wait..wait...wait (very fast) are you saying we a have a full functioning emulator right now??!!!



A....are you saying I can go to the zone now and play with it no problem!!!???



I AM SOOO HAPPPY!!!

Compile with 'NDEBUG' as a preprocessor definition to ditch the ASSERTS

[NovaCoder]

Sounds like you are getting somewhere though, well done

[emufan]

@xboxown: just a littlebit *hopefully*

ok, will do.
I just saw it does now read and write from/to the config file.

You need to do a printf of some of the data it's reading to see if you need to perform a byte swap.

I have byte swap code if you need it

will try that.

NDEBUG || NODEBUG did work ( i inserted both)

one little problem, when starting the emulation.
i had a build where it painted a black screen only, now i get those random chars,

at the moment i cannot remember what i did to make it black.

zoned: AmiApple-WIP.lha images and config and some dsk included.
it does need ixemul.library v48 or newer.
if you have a rtg workbench, it will start in a window, otherwise it will open a new rtg screen.

#1) if you run with -b option (benchmark) it fails after a while
with an error when doing cpu benchmark,
maybe this is something to investigate.

It looks beautiful! The quality and brightness and color matches 100% as a real Apple II running on TV in every regard. Amiga does better job emulating the proper feel of consoles and computers than a PC does for some reason.

However, even if I press F2 or load a game it doesn't start it just leaves you with # and @ filling the screen but nothing else. Am I missing something or it is not fully functional yet?

noixemul has its benefits and afaik, the gcc6 toolchain (which I am using) doesn't fully support ixemul at the moment.

Didn't you read the post you quoted?

[xboxown]

Eh? -scratches hair- What post that I quoted? OH!! Nevermind! Good progress though!!

[gulliver]

Great work!

Keep it rolling...

[emufan]

@xboxown: F2 should start the emulation, but something is wrong here,
still investigating.
you can edit the linapple.conf, change computer type or other things.
maybe one combination does work, out of the blue. dunno.
