I have been looking and tinkering with your OS X port and was not able
to get any translation working until I fudged with a couple of things.
The most important of those is in vl.c -> search for valloc() -> you
will see an attempt to allocate *page_size x all memory* change it to
*all memory* and you will be on your way. Here is a log from my
changes:

I am still fiddling around with it and trying to wrap my head around
what Fabrice has done, but will post a diff if anyone wants it.

Hi all!
I finally made the dyngen tool mach-o compatible. But it is still not
working, when I do:
i386-softmmu/qemu /path/to/linux.img -d
I get two block of instructions translated, but it ends in a SIGBUS
with the following backtrace:
#0 0x00013ba4 in cpu_x86_exec (env1=0x1d) at

(To this email is attached the log output)

I was wondering if the usage of qemu was correct. Can someone point me
to the right direction on how to debug qemu and/or give me some help
on this issue.
Here is a patch to make qemu build on Darwin. It is not cleaned enough
to be integrated in CVS as is, but it will be soon. Also configure
doesn't work properly so you'll have to edit configure output by hands
on Darwin.
