Snow Leopard on Unsupported PowerPC Macs

Status
The first post of this thread is a WikiPost and can be edited by anyone with the appropiate permissions. Your edits will be public.
Since we’re on the topic of ZFS, I spent a bit of time digging through the install packages in Builds 10A286, 10A222, 10A190, and 10A314 to find how ZFS/zpool development evolved.

In short, everything from Build 10A222 forward is no longer a UB, but Intel-only.

This becomes noteworthy when, in Build 10A286 (the furthest along Apple got with ZFS development), there are three PlugIns added to Disk Utility.app which are specific to ZFS — namely, ZFS.dumodule; ZFSFilesystem.dumodule; and ZFSPools.dumodule. These plug-ins were removed by the time 10A432/10.6.0 was released for sale; in fact, these were removed from Build10A314, the immediate successor of Build10A286 available to developers.

In short, this means whatever disk formatting options available to Disk Utility.app in Builds 10A96 and 10A190 will not have options for formatting to ZFS — at least not from a GUI standpoint. As to whether one can do so on an Intel Mac running 10A286 has yet to be determined.

When you have time (and mood), please update us on your progress with improving OS components. I am very much interested in this, but at the moment busy with other stuff: attempts to fix ghc compiler for PowerPC, gcc10-bootstrap port and improving fixes for libsdl2 and libvpx.

I will always return here with findings and updates, but it is more a matter of time than mood i’m afraid. Please don’t take my absence as disinterest at all - i’m just extremely busy in real life. Will try and post something useful soon.

This gonna depend IMO on a nature of your work. To me 10A190 appears almost fully functional, however there is some stuff that is broken, even though it may not be a concern for you or someone else. Say, Pacifist does not work, iWork does not even install correctly, ppc64 support is missing altogether.
And the same time it may be perfectly okay if you work in Word or Adobe CS, though I have not tested thoroughly either.

As for coding, it works, but it is an odd choice, severely limiting your options to get support: perhaps no one gonna accept tickets against an obscure developer build. At the same time it can be fun: you can do something that literally no one ever did.

It all depends on what you want to get from it. You haven’t specified.

And I know you know what that answer is going to be.

[Without clicking the link, you know what that answer is, don’t you?]

If you’re so consistently incurious to avoid exploring, finding out, and learning what you can and can’t do with these builds on your gear, then you really have no leeway to keep pestering the project volunteers like this.

Life is short. Live a little and embrace curiosity.

FIXED! Airport Extreme is now working!

View attachment 919071

And somewhat fixed AirPort section of System Profiler. But it is incorrect detect status of AirPort Extreme. Actually it is active...

View attachment 919072
What to do with that little bugs is still a question. And in logs many errors about CarbonLib or something...

To make AirPort Extreme working, we need to import these components from 10A96 above the same in 10A190:
/System/Library/CoreServices/Menu Extras/AirPort.menu
/System/Library/CoreServices/Apple80211Agent.app
/System/Library/Frameworks/AirPort.framework
/System/Library/PrivateFrameworks/Apple80211.framework
/System/Library/Extensions/IO80211Family.kext
/usr/libexec/airportd
Click to expand...

For whatever reason does not work for me on PowerBook 12". I was able to get Airport into menu bar and System Preferences, however it fails to connect. Also in System Profiler trying to check Airport Card info results in a crash.

Any advice? I would really hope to get Airport working.

How to make Airport work on 10A190 and PowerBook A1104?

Ok, a replacement for Leopard?
 
ChrisCharman said:
Try using darwinbuild via macports as it should automatically set the correct build environment and resolve the dependencies. I was about to do this myself but after just getting home from work my G5 has decided not to boot - i’m hoping it’s not a power supply or processor failure. Don’t have any spare PRAM batteries laying around either.

You’ll need to install command line tools from 10A096 installer, followed by building MacPorts from source and then $port install darwinbuild

Hopefully i can get back up and running soon.
Click to expand...

darwinbuild does not install as ppc-only, at least as-is. Did you install i386+ppc or how exactly?
Also, did you use darwinbuild-legacy or darwinbuild?
 
Natively built gcc11:

Code: 
36-72% port -v installed libgcc11
The following ports are currently installed:
  libgcc11 @11.2.0_3 (active) requested_variants='' platform='darwin 10' archs='ppc' date='2022-03-09T07:19:42+0800'
36-72% port -v installed gcc11
The following ports are currently installed:
  gcc11 @11.2.0_3 (active) requested_variants='' platform='darwin 10' archs='ppc' date='2022-03-09T01:38:58+0800'
36-72% port -v installed libgcc
The following ports are currently installed:
  libgcc @5.0_0 (active) requested_variants='' platform='darwin 10' archs='ppc' date='2022-03-09T07:26:11+0800'

Compiler appears fully functional, due to upgrade of libgcc earlier problems with gcc10 got solved too, it seems.
At the moment I think we can completely move to gcc11 as the main compiler on 10A190.

Has anyone tried to install 10.6 PPC versions in a virtual machine on an Intel Mac?

Parallels Desktop supports only Server versions for 10.6, however for whatever reason 10A96 Server does not install for me. I did not yet try other options.

P. S. Is it the case that we do not have 10A190 Server?

Build 10A190 Server has never turned up throughout the duration of this project, no.

But you might be able to coax the Client build into a Server build. If the plist file isn’t present, you can probably bring one over from another Server build and make the adjustments inside the plist itself to match wha you have.

Was not Sorbet Leopard exactly what you guys are trying to do ? According to the author, it already implements Snow Leopard characteristics inside though I may be wrong. He told me it kind of does.
 
ChrisCharman said:
I’ve run into similar problems trying to set-up DarwinBuild for PPCSL - seems the environment for Darwin 10 has been set up for intel only which isn’t surprising.

I’m still personally trying to figure out how to create a reliably sane environment but at the moment i’m just manually downloading and compiling the tools i need individually for each project i try to build. Lots of ‘chicken & egg’ unfortunately, and i’m not able to spend more than a few hours here and there a week on this. Compiling the tools alone keeps my old PPC systems nice and warm while i’m at work.

Hopefully once most of the base system has been recompiled to be closer to parity with the release versions we might be able to bootstrap some tools to the new system and build from there...or i could be completely wrong as i’m really just learning this stuff as i go which is part of the fun for me.

If you manage to get DarwinBuild functioning please do let us know as it would make things much easier.
Click to expand...

Have you succeeded to set it up at least on 10.5.8? (Sorry, I know I already asked you here, but just in case you didn't see.)

There are two versions, darwinbuild-legacy and darwinbuild, as of now either fails for me on 10A190. The latter on Database.cpp in darwinup target. However it might be possible to fix it. Xcode project can be edited manually, specifying correct arch, then just rerun "sudo port -v build", it resumes. Of course I have no idea if it actually can be fixed.
Conceptually it is unclear for me however which route is the way to go: try to fix old legacy variant and add a plist for 10A190 or rather work on darwinbuild proper by adding ppc and likely removing some parts that fail no matter what.

What do you think?
 
diggledude said:
Has anyone had success using darwinbuild to build anything? It seems darwin strictly aligns with mac os x and the first build of darwin 10 got rid of ppc architecture. I edited the plist to add ppc but once it generates the build script it just returns "bad CPU type in executable."
Click to expand...

Which version have you tried? If in Macports, which archs did you choose for +universal?

P. S. In fact for me in fails even on 10.5.8: I am a bit surprised how you guys apparently got it going with no pains. See: https://trac.macports.org/ticket/64830

I was genuinely surprised to discover this fact: for some reason I believed we had both bootable OSs in both forms.

Are you using 10A96 now on a PowerBook btw? Could you say if Airport works and if yes, then how to prepare an installable image? I saw the Wikipost of course and following comments, however my attempt to replicate failed (it installed initially and booted once, after which failed; I am not sure now which OS I tried). It would be helpful to have a step-wise procedure confirmed to work for 10A96 and a PowerBook.

P. S. I you have time and some interest left, could you test gcc10-bootstrap and gcc11 from here? https://forums.macrumors.com/thread...-6-powerpc-10a190-and-10-6-8-rosetta.2332711/
Should build and work on 10A190 and provisionally on 10A96 (I cannot verify the latter atm).
 
ChrisCharman said:
I was thinking earlier today about the need for a dedicated ‘PowerPC Architecture Development Reference’ thread and how we could leverage the combined knowledge of the community with a wiki and reference manuals/documentation. Does anybody know if this already exists on MR? If it doesn’t i feel it would be useful to start one for many reasons, and could of course benefit this project and future projects.

I think we might be at this point actually where it makes sense.
