But it is opening OpenAL from somewhere since it did crash in an OpenAL method. ;-)

The hangs appear to be different.

Install SDL2 i had been noticed where you can find it ... openAL is needed .. i have it in my frameworks probably come with some software or with lastest osx dev kit for leopard ppc :-) in any way better have the frameworks in the library dir :-P

I have the same problem
Before crash this is the last screen what I can see: "Loading AmigaOS 4.1 Final Edition Kiskstart.."
The last working for me version is 2.5.30

yes SnakeCoils forgot to put the patches on last builds.

It is not even crashing, just does not load qemu plugin

I forgot nothing. I always pick the official source and I compile it following the steps I have illustrated here:

http://eab.abime.net/showpost.php?p=...&postcount=229

If the resulting build is not suitable for your needs (for mine it works) please install the dev tools on your system and make the modifications you want.
As far I can understand the problem with Amiga PPC environment is related to an external plugin not to the FS-UAE main structure so it will be more productive to focus the efforts on this point instead of patching something that is not strictly needed. What I am saying here is that every issue must be solved in the source when the origin of the problem is in the source, if it is outside is not a Frode's business.
I am not the OSX PPC mantainer for FS-UAE, I simply compile it from the source and then I do a quick test to see bugs or improvements giving a feedback to Frode if needed. But everyone else can do this.
I am not interested in the Amiga PPC evolution, only the 68k chapter is important to me and I am doing my best to do a quick and accurate report of issues on this side.
Tlosm, I do not include your patch because I think that an AmigaPPC machine that is not fully functional starting from the source should not be enabled because when users reports an issue about that is not clear if the origin is in the FS-UAE source or in the modification made to allow it to boot: if you made changes to the source you are responsible for that changes and you must provide support for that. Can you see the point?

Did you installed my last one qemu plugin ?

@SnakeCoils
I will mantain it but im swapping home and need to clean my Quad G5 because i make to much rubbish inside the dev box and not build nothing any moore ...
In november i think i will start again build it

I also tried this version but the same effect.

The SnakeCoils is not with my PPC patch for have Os4 running on it .
you can download my old build from here

Hello again. I see my thread is still active. Here is a link to SDL2 if needed.

Looking in The Zone! seems that someone has niceley compiled a modified 2.7.2dev with OS4 compatibility...

@SnakeCoils who is this one ? ;-)

Thanks for the hint. I tested this with a default config and it loaded up but seemed dead slow. The sound stuttered badly and it took ages for AROS KS to load up. I think it also took a toll on my system. I was able to close it once I got my pointer back. Any log output be useful in seeing what was holding it up?

@Hypex
A big effort has been put in FS-UAE to have an highly portable emulator that can run on a variety of different platforms and therefore is little optimized for specific platforms, the poor performance on PPC hosts is because a great accuracy in the Amiga emulation but also for the lack of a JIT recompiler for PPC hosts (like PowerMacs) that could boost a lot some things.
Additionally when the PPC guest emulation is needed (Blizzard or CyberStorm PPC) the PPC hosts (PowerMacs) cannot at present take advantage of this, since every instruction must be "rebuilt" and not passed to the host CPU directly.
If you want to run AmigaOS4 in a useful manner go straight to x86 hosts, you will not be disappointed expecially after the recent progress on JIT x86 recompiler.
The only solution for PowerMac users (or other PPC systems) is that someone skilled enough in PPC assembly would join the FS-UAE development to add a proper JIT recompiler also for PPC hosts, a 68k recompiler would be already a big, big improvement.

[FrodeSolheim]

Btw, there already exists a M68K -> PPC JIT compiler (for E-UAE): http://euaejit.blogspot.no/. Should be possible to integrate, but probably requires at least a semi-skilled developer (I haven't look at the code)

Yes Frode was made by a friend of mine:Almos ... and it is really working good .
On AmigaPPC and on Apples PPC . it was Tested by me :-P

[SnakeCoils]

It would be great if Almos will give the permission to use his 68k JIT engine in the FS-UAE emulator, additionally there are optimized versions also for G4 and G5 PPC hosts.
I really hope the E-UAE JIT integration in FS-UAE will happen and it will not cause too much headaches to Frode ;-)

[Hypex]

Argh!!! It's done it again! Twice! EAB asked me to log in when I wanted to preview it and deleted my entire post again! This site is frustrating. And a lot of sites are doing this now. Time to give up and uninstall the internet from my computer!

As long as that platform is little endian.

and therefore is little optimized for specific platforms, the poor performance on PPC hosts is because a great accuracy in the Amiga emulation but also for the lack of a JIT recompiler for PPC hosts (like PowerMacs) that could boost a lot some things.

In my case I don't need JIT at all. I was just using a generic setup with an AROS A500. It has no cache.

But maybe this is a Mac thing. Despite having OpenGL and HW acceleration I always find UAE performance on my Mac is crap. I play Worms AGA on my G3 800Mhz A1 with EUAE and it's fine. On my Mac G4 1.5Ghz it stutters! :-?

Using it as an RTG setup appears to work fine. My G3 500Mhz Mac was okay emulating Workbench and I even booted it to use the OS3.9 search feature when I couldn't figure out how to use Spotlight. Which still misses files.

Additionally when the PPC guest emulation is needed (Blizzard or CyberStorm PPC) the PPC hosts (PowerMacs) cannot at present take advantage of this, since every instruction must be "rebuilt" and not passed to the host CPU directly.

Well PPC performance is not my problem. My problem is I can't even get the PPC to work at all. I am emulating a dead PPC CPU! I've seen the real thing.

If you want to run AmigaOS4 in a useful manner go straight to x86 hosts, you will not be disappointed expecially after the recent progress on JIT x86 recompiler.

I just want to run it at all! I just want to see it boot! But it seems on PPC this is too hard. There is no user friendly compile of FS-UIAE you can download from a public place that works out of the box. This is what I can gather. So you need to download this program from this forum you don't have an account on in a section you need to register another account on. Then download this file from another site where you also don't have an account on and rip some system file out and stick it in your system. Then you need this other system file and good luck finding it! And you should have XCode and all this other stuff installed and use it to install these other files. I'm serious! This has pretty much been my experience! And that didn't include all the ROM files you need aside from FS-UAE itself! :O

I am using Mac OSX, where it is meant to have user friendliness and higher standards. I am not using Amiga x.x where the standards are lowered because Amiga programmers don't know nor care to package things correctly nor test it on a base system and the users accept it because it's Amiga. Just because I am using an Amiga related program why do I have to search all over the internet looking for system files? Sorry but I find the standards in the Amiga scene have really dropped in recent years.

A friend asked me to send links of where to get FS-UAE and what ever else needed. Being new to OSX/PPC. I was almost filled with dread. I spent over an hour trying to collect all files and email it. That mostly were on my system. OSX doesn't help when it converts zips to folders and doesn't let you look inside a zip. Especially when the download link is broken. The one I posted is broken now and I don't know where you get SDL2 from now. And I don't know if it will even work on another system.

The only solution for PowerMac users (or other PPC systems) is that someone skilled enough in PPC assembly would join the FS-UAE development to add a proper JIT recompiler also for PPC hosts, a 68k recompiler would be already a big, big improvement.

As stated, there is already 68K JIT. But I don't think a PPC JIT would be needed. Well not like for x86. Being the host is PPC it makes sense to execute the code directly and the OS4 powerpc.library is an example of this. 604e code can be quite compatible with a G3/G4. I think if it examines code, copy what's compatible then filter out what isn't and convert it to a substitute, that could work. The only problem then is memory read/write access where it tends to get converted into a hook call. Possibly the MMU could be programmed here so the original code could run and exceptions used to hook into memory access. Then the code could run at near host native speeds. On par with x86 speed but still short.

[tlosm]

Hypex,
from my side on my quad working mine old ports and the last SnakeCoils too. everything run like it have to .
im pretty sure you need some library in your mac... in past i had crashes because i dont know why leopard installer install x86 libraries and not PPC

[Hypex]

Hello back after some testing.

Well I've put everything in that I've read about. It would help if each build included all the needed libs and whatnot. It seems a bit pointless to me for someone to say it needs this or that with their build of software when they could just include it! Yes I know it's in a beta state but people will be unable to test if they need to be a programmer with a full dev set up on their Mac. Not everyone is like that. ;-)

I've found with the FS-UAE 2.7.2dev build that it can be tripped easy and crash. For example I was testing with cdrom_drive_0 and used cdrom_image_ 0 instead. It just crashed randomly.

There is a problem with the PPC emulation. I found today it doesn't load it for some reason. And then crashes. Given it looks like a loading error I wonder why it crashes. Seems to be a bit disorganised for an OS to just crash when a binary doesn't load.

Here is a log I managed to grab from the CLI:
