Andreas Färber - April 30, 2012, 10:15 p.m.
From: Andreas Färber <afaerber@suse.de>

It's been orphaned, not compiling for a long time and despite Apple's
drop of their Rosetta ppc emulation technology with Mac OS X Lion no one
has stepped up to fix it.

Testing necessary changes wrt QOM'ification thus is impossible, so we
might as well remove it completely.

-In order to launch a Mac OS X/Darwin process, QEMU needs the process executable
-itself and all the target dynamic libraries used by it. If you don't have the FAT
-libraries (you're running Mac OS X/ppc) you'll need to obtain it from a Mac OS X
-CD or compile them by hand.
-
-@itemize
-
-@item On x86, you can just try to launch any process by using the native
-libraries:
-
-@example
-qemu-i386 /bin/ls
-@end example
-
-or to run the ppc version of the executable:
-
-@example
-qemu-ppc /bin/ls
-@end example
-
-@item On ppc, you'll have to tell qemu where your x86 libraries (and dynamic linker)
-are installed:
-
-@example
-qemu-i386 -L /opt/x86_root/ /bin/ls
-@end example
-
-@code{-L /opt/x86_root/} tells that the dynamic linker (dyld) path is in
-@file{/opt/x86_root/usr/bin/dyld}.

 Linux user emulator (Linux host only) can be used to launch the Wine
-Windows API emulator (@url{http://www.winehq.org}). A Darwin user
-emulator (Darwin hosts only) exists and a BSD user emulator for BSD
