SheepShaver Issues with Ubuntu 14.04 x64

[UbuntuXP]

Hi,
I managed to compile the SheepShaver source code, but it fails to boot a Mac OS 8.1 install iso I have. I did set it to read-only, and it installed in Baslisk II (which I also compiled.) Here's the output:

$ ./SheepShaver
SheepShaver V2.4 by Christian Bauer and Mar"c" Hellwig
Reading ROM file...
Detected CPU features: MMX SSE SSE2 SSE3 SSSE3
PowerPC CPU emulator by Gwenole Beauchesne
Segmentation fault (core dumped)

Anything I'm missing?

Hi,

No, I have the same issue in my Ubuntu 14.04 virtual machine, even with the jit-compiler disabled.

This is what gdb has to say:

It seems I also can't get SDL-1.2.15 built on this Ubuntu version.


Older versions of SheepShaver for Linux downloadable from our forum do work.

Best,

Here's what I got using gdb:

I used a Mac OS 9.0.4 install iso and a couple of new-world roms this time. I tried to compile without jit and/or sdl, but it wouldn't make if I disabled those features.

[adespoton]

Your best bet is probably to run the Windows version in WINE, or use one of the precompiled ones on here; but if you want to track down the problem, we'd all appreciate it

[UbuntuXP]

I think the problem is in the cpu emulator itself, so someone needs to fix/replace that.

[uyjulian]

Yeah, CPU emulator is from about 2003: http://gwenole.beauchesne.free.fr/kheperix/

I might see if there are more suitable replacements.

[adespoton]

the MESS PowerPC code is also more recent, as is the QEmu PowerPC code.

Dolphin may be the best bet however, although it doesn't capture the exact CPU variant we're dealing with here.

Yeah, not exactly.
Dolphin somewhat like a G3 with some other features.

[uyjulian]

MESS and Dolphin don't have G4 emulation.
Qemu has G4 emulation but is missing AltiVec.

More importantly,
What language are they all written in? I haven't looked at the core emulation source for years now.

Maybe my next project will be refreshing the SS/PearPC core emulation based on the others as reference -- which would have me completing it in a decade or so

All of the sources of the three emulators are written in C(++).

I figured out something, both SheepShaver and Basilisk II will not work with more than 8mb ram at all. It works fine with 8mb, but if I set it to 16, it crashes.

[UbuntuXP]

I can confirm that Basilisk II can't run with more than 10mb ram. I don't know about SheepShaver. I'll try again next week.

[adespoton]

Back in the day, my Mac wouldn't address more than 10MB of RAM anyway... even though it required 12MB RAM installed to address 10MB. Of course, it was able to use Virtual Memory too.

[Ronald P. Regensburg]

I can confirm that Basilisk II can't run with more than 10mb ram.

It must be an issue that is specific for the Linux version and/or your specific (Ubuntu x64) host system.

On OSX I run BasiliskII with 256MB RAM and SheepShaver with 512MB RAM.

[UbuntuXP]

I think it's how it compile, because builds for previous versions of linux will work.
