Q is QEMU with a coca GUI on the front, and it works amazing! I’ve been testing it out the past few days, and I have yet to have a problem with it. Instead of trying to compile QEMU yourself on Mac OSX (Lion or otherwise), go to the Q Homepage and check it out.
I am using version 0.9.1d118, and that one works. I am actually running a kernel that I wrote myself on it, and no problems yet!
I finally got QEMU to compile! It took me a little bit to figure out everything that it needed, but I finally got it! However, a couple of the romfiles that it needs to run never compiled. They are vgabios-cirrus.bin and pxe-e1000.rom. Guess I get to go back in and figure out what went wrong.
If anyone has any insights, please leave a comment or send me an email.
UPDATE: If you want to use QEMU on Mac, use the application called Q, which is a mac wrapper for a successful build of QEMU. Link to post on Q
