Installing Rosetta on Lion

[hyperblue]

I've tried installing the SL package of Roestta on Lion and it is a terrible no go. I've been poking around to see what frameworks are needed from old SL in order to get Rosetta to work, but I'm still getting errors.

 

Does anyone know if Rosetta is dependent on the Kernel or just frameworks? Also, is anyone else working on Rosetta support for Lion?

I've tried installing the SL package of Roestta on Lion and it is a terrible no go. I've been poking around to see what frameworks are needed from old SL in order to get Rosetta to work, but I'm still getting errors.

 

Does anyone know if Rosetta is dependent on the Kernel or just frameworks? Also, is anyone else working on Rosetta support for Lion?

 

so far I investigated a bit

 

in Snow all Rosetta sits in

 

/usr/libexec/oah

 

installing only the rosetta pkg in lion installs only the exe "translate" which is rosetta itself.

 

but it relies on shims and symlinks to system files

 

I have extracted all from SL 10.6 disk via pacifist . With packagemaker I could do a Installer for it, that is no the problem.

 

Activating the translate executable ( associate it to open ppc apps ) would be done by this :

 

sudo sysctl -w kern.exec.archhandler.powerpc=/usr/libexec/oah/RosettaNonGrata

 

sudo sysctl -w kern.exec.archhandler.powerpc=/usr/libexec/oah/translate

 

In Lion and Snow exists a exec file in the directory called RosettaNonGrata :

 

opening in Textedit and comparing them :

 

In Snow this will tell you to install rosetta to run ppc

 

In Lion it will simply bring up the error message that ppc is no longer.

 

 

question is how and where Apple has blocked to run the translate binary..

[smartie77]

I found the answer : they disabled it on a kernel base plus removed the files in Lion ..

 

In SnowLeo mach_kernel it contains reference to /usr/libexec/oah/translate ( the rosetta binary )

 

In Lions mach_kernel all references to /usr/libexec/oah point to "RosettaNonGrata" ( the exec which says ppc support is dead on Lion )

 

see :

 

 

 

So someone needs to recompile the Lion xnu kernel and re-enable it. If we have such a ( otherwise unmodiefied ) 10.7 kernel, adding back the files to /usr/libexec/oah and telling sysctl to associate powerpc apps with /oah/translate it could work again.

 

files needed in /usr/libexec/oah :

 

 

( my sl.rosettanongrata is the snow version of the same file,obviously we would need to replace the lion version with the sl version -- the "Shims" folder has all frameworks included that it needs)

 

I never worked with OSX kernel, but I have knowledge how to reconfigure Linux kernels.. I might dive into that now and only for a software.. I never needed a modified Apple kernel for my hardware, this is totally crazy ..

 

update - i did a compile on 10.7 kernel just to get a feeling for it and have now 2 mach_kernels, 32 and 64.. so at least I know now how to use the tools ;-)

 

will dive into that later.

Great research smartie! It seems like you'll soon become the digital savior for many Lion users.

Please keep us updated!

 

(didn't even know the Lion kernel source was out yet)

 

Hrm, unfortunately I don't think Rosetta does any ISA translations. This means for Rosetta to work, you will need to have the PowerPC libraries as well. Snow Leopard libraries are FAT and contain the compiled PowerPC binaries. Lion will lack these, so running Rosetta on Lion will require having, at the very least, the Snow Leopard libraries as well.

 

It may be possible to install the Snow Leopard binaries in ~/Library or someplace else and use the DYLD_LIBRARY_* flags point to it. At first I would try running a simple terminal command like Hello World then try a simple Cocoa or Carbon PPC app.

[earcaraxe]

AFAIK, but I could be wrong: I haven't gotten into anything regarding kernel recompiling, but unless I'm totally understanding something wrong, if translate were installed correctly and had all of its library dependencies, etc, there shouldn't be anything stopping us from running it manually from the commandline.

 

I copied /usr/libexec/oah/ from a snow leopard machine to /usr/libexec/oah/ on my lion machine. I am showing the same file listing as smartie77. When I attempt to run ./translate I get segfault 11.

 

I have pulled the crash reporter log and posted it here, just for posterity. I'm pretty sure the issue is mainly what anarkhos said regarding the libraries lacking all the code they need, but my knowledge of segfaults is super limited.

I do not use Lion yet so I can't debug your error. You have to use gdb to debug the problem.

 

The error simply means you're trying to access an address in VM which doesn't exist or you don't have access to. Usually it means you're trying to access memory that has been released or a pointer that has been overwritten.

 

translate only links to four libraries:

 

otool -L /usr/libexec/oah/translate

/usr/libexec/oah/translate:

/System/Library/Frameworks/IOKit.framework/Versions/A/IOKit (compatibility version 1.0.0, current version 275.0.0)

/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0)

/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 697.0.0)

/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.11)

 

One can inspect further and see what functions are called and build shim libraries if the Lion ones do not work for whatever reason. Do the listed libraries even exist in Lion?

 

At any rate, these libraries are all open source. For those not in the know, libSystem.B.dylib is an amalgamation of various static libraries in an 'umbrella' library. If you want to know why translate is crashing, you have to use gdb.

[earcaraxe]

Apparently upgrading to lion broke all of my xcode tools, so I'm currently updating my tools. In terms of libraries, I took a look and have this to report:

 

/System/Library/Frameworks/IOKit.framework/Versions/A/IOKit

This exists.

-rwxr-xr-x 1 root wheel 1178960 Jul 28 15:55 IOKit

 

/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0)

I'm showing:

bash-3.2# ls -al | grep libstdc+

-rwxr-xr-x 1 root wheel 1595728 Jul 28 15:55 libstdc++.6.0.9.dylib

lrwxr-xr-x 1 root wheel 17 Jul 28 15:56 libstdc++.dylib -> libstdc++.6.dylib

 

So again, it looks like it exists, although it appears to be a smlink to libstdc++.6.0.9.dylib

 

/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 697.0.0)

This, when I search for it, is just again a symlink, but it's a symlink to libSystem.B.dylib

Which fits your description of it being an amalgamation of libraries.

[mePy2]

Is there anybody out there?

[Sam from Stack Exchange]

@mePy2 yes, I am (6 months later).

I'm starting to look into making Rosetta work on macOS Sierra, and have a question about it on Stack Exchange.

@anarkhos did you ever get Rosetta to work on Lion? Do you know if any more work was ever done on running Rosetta?

Try to look here: https://forums.macrumors.com/threads/installing-snow-leopard-and-rosetta-into-parallels-7-in-lion.1365439/page-21

Also Rosetta won't go with applications depending on one or more PowerPC-only kernel extensions.
