I am close to porting AppleWin for Amiga.

If I find something more regarding my porting efforts, I will post here. I know not of much help, except showing that it can be done. But at least you shall try examining the AmigaOS 4 binary.

Do you have the source code for AppleLin for AmigaOS 4.x? That helps way more than the binary version.

not sure. for now we have to wait for an update of the crosscompiler,
or someone who can tell us what we are doing wrong.

i found a simple source code, which uses setitimer function.
i can build the binary on cygwin with g++ v5.4 - while building the same with
m68k-amigaos-g++ v6.3.1 - i get a big list of different errors.

so i think something is wrong with the crosscompiler.

@drHirudo: do you remember which compiler you were using?

It's not the cross-compiler's fault. It's some library. Probably ixemul does not implement the scheme.

[NovaCoder]

How are you setting those timers?

I don't think you should be calling 'SetTimer()' you should be using SDL Timers if you are using SDL.


https://wiki.libsdl.org/SDL_AddTimer


Also about the missing SDL Joystick functionality...I'd advise that you to simply stub out the SDL Joystick calls in 'Joystick.cpp' and use my latest SDL_AGA.lib from AmiNet, after you get it up and running you can then worry about implementing the joystick handling.

but we get the error messages while building the binary with option "-noixemul" - so something in the crosscompiler package does not work as intended.

and i cannot find anything with "setitimer" in the link libs. i'm no expert but from the looks, something is missing.

hmm, i dont set anything, i just take what is given in the emulator sources

the trouble is, i can build the SDL-AGA version, but only if i remove and "fix"
the setitimer calls.
so this might explain the sdl-aga error message about missing timer support

I used GCC from the AmigaOS 4 SDK back then. The sourcecode I have is unmodified. For my porting purposes I usually use modified .h files with custom #ifdef, #ifndef and #DEFINE directives in order to keep the original sourcecode unmodified.

i had a look at the os4 sdk on the hyperion website.
just did a simple grep on those link libs and found no "setitimer".
so if you managed to compile it with the same restrictions,
your custom definitions could help alot

What?! That's it?

[xboxown]

Is it officially dead? Do we cancel the entire project?

waiting for drHirudo and his source code,
I hope he will find and share it

drHirudo what gives man??! - claps hands very fast - chop chop man! We are waiting for you!

Ever heard of vacation?

[xboxown]

Vaca.... what? Will I hope he have a happy and restful vacation

Sorry, for the delay. My Amiga X1000 is in the other room and I didn't have the time to move it and turn it on to look for the sources. I hope Hyperion/Amiga will be okay with me distributing modified .h files from the SDK. Well, just saying because unexpected things can pop up from anywhere. Two years ago my PayPal account was terminated because they accused me of selling emulators! (just because I hosted them on my website!) and killed all my motivation for coding at all. The account balance was 0 and they allowed me to open a new account (probably realizing their mistake, but didn't want to acknowledge it).

Quite the opposite actually. The last few weeks I lost sleep and I am fighting constantly with YouTube and their bugs they introduce that broke hundreds of my videos. I write to them pointing out where the bugs are and why they happened and how they can fix them, but they just reply to me some paste text and didn't look at all what I am pointing to them, asking me to re-upload terrabytes of videos, because it will be easier for them that way. So, if they don't do anything (most probably), I have to fix hundreds of videos manually for weeks, without any warranty it will work or wont broke again in the future. They promised me 4 months ago everything will be okay and it will not break, but it happened, so I lost belief in YouTube technical support.

Advice to all that?

-hands you a cup of cold fresh water with couple of fresh ices-

[xboxown]

I am just saying that it is ok about applewin being cancelled or not ported. I am deciding to get the real apple ii machine instead.

[emufan]

dont be disappointed. there is still some hope, if we can get the scr code of the os4 version.
maybe this will help to make a os3 port.

Hiya,

I had a quick look at the source linapple_src-2b.tar.bz2, I think this is a better version to use than the updated RetroPie source. If you could get it working then you can always update it with some of the newer stuff.

The main stuff I changed was:

Replace thread handling to use SDL:

// for CRITICAL_SECTION handling
// NOVA_CODER - #include <pthread.h>

// NOVA_CODER - pthread_mutex_t g_CriticalSection = PTHREAD_MUTEX_INITIALIZER;
SDL_mutex *g_CriticalSection = NULL;


void CpuIrqReset()
{
	_ASSERT(g_bCritSectionValid);
	if (g_bCritSectionValid) SDL_LockMutex(g_CriticalSection);
	g_bmIRQ = 0;
	if (g_bCritSectionValid) SDL_UnlockMutex(g_CriticalSection);
}

Replace Timer handling to use SDL:

/* NOVA_CODER
#ifndef _WIN32
//for Timers try to use POSIX compliant timers
#include <signal.h>
#include <sys/time.h>
#endif*/

bool SysClk_InitTimer()
{// first initialization of the timer
/*	memset(&sa_SysClk, 0, sizeof(sa_SysClk));	// clear sigaction struct
	sa_SysClk.sa_handler = &SysClk_TickTimer;
	sigaction(SIGALRM, &sa_SysClk, NULL);	// set SIGALRM handler*/
	//if(signal(SIGALRM, SysClk_TickTimer) == SIG_ERR)
	//	return false;

    // NOVA_CODER
    SDL_TimerID SDL_AddTimer(Uint32 interval, SDL_NewTimerCallback callback, void *param);

	printf("Timer has been initted!\n");
 	return true;
}

This now compiles but has a lot of conversion warnings, probably not that well written I'd guess...I'm also not sure about the use of CURL (I'd probably replace it). I'll attach the workspace that I used for those updates.

Hope that helps.

thanks alot Nova

while building with SDL_AGA, i get these linker errors:

../SDL/lib/SDL_AGA_040.a(SDL_joystick.o)(.text+0x10):SDL_joystick.o: undefined reference to `_SDL_SYS_JoystickInit'
../SDL/lib/SDL_AGA_040.a(SDL_joystick.o)(.text+0xcc):SDL_joystick.o: undefined reference to `_SDL_SYS_JoystickName'

../SDL/lib/SDL_AGA_040.a(SDL_joystick.o)(.text+0xa0e):SDL_joystick.o: undefined reference to `_SDL_SYS_JoystickUpdate'
collect2: ld returned 1 exit status

in sdl_joystick.h i tried to define it, without success:

m68k-amigaos-nm.exe SDL_AGA_040.a
...
000007de T _SDL_PrivateJoystickHat
         U _SDL_SYS_JoystickClose
         U _SDL_SYS_JoystickInit
         U _SDL_SYS_JoystickName
         U _SDL_SYS_JoystickOpen
         U _SDL_SYS_JoystickQuit
         U _SDL_SYS_JoystickUpdate
...

older version and rtg got the "T" next to the "U" entry for SDL_SYS_... but it is missing in latest aminet version.

extern DECLSPEC void SDLCALL SDL_JoystickUpdate(void);
extern DECLSPEC void SDLCALL SDL_SYS_JoystickUpdate(void);

this doesnt happen with your earlier version of sdl-aga nor the rtg version.
any idea?

[NovaCoder]

I'd just use the older RTG version of the SDL to get it up and running first.
