qemu uncaught exception

[frozencemetery (Robbie Harwood)]

It appears as though qemu is unwilling to function without opening a window (i.e., while running headless). Trace follows:

Noted, thanks for letting me know!

Unfortunately, this due to the way the Mac OS X support has to be implemented in qemu. To make it run as an app, the main function is replaced with a wrapper that acts as an event loop.

In r118754 I split the cocoa and curses interfaces into conflicting variants. To get the curses interface now, please run the following commands. Note that this version will not support the graphical user interface at all.

sudo port selfupdate
sudo port upgrade --enforce-variants qemu +curses

Another note: Although the curses interface builds and works for a simple test case for me, I could not get the monitor console (open with <Esc>2) to work properly. It always displayed black text on black background for me, so that the text could only be revealed with a selection in Terminal.
