I got some problem when installing the xv6 on my Mac

[PKUFlyingPig]

I tried to install xv6 on my Mac follow the install notes, after all the work, when I run "make TOOLPREFIX=i386-elf- qemu-nox" in the xv6-public, it began to show the above again and again. Is there some problem? and after I install Qemu but before the second software to be installed, when I run"qemu-system-x86_64 -nographic", it showed as follows

So where is the problem?

You're best off bugging the MIT folks per xv6 problems. This guide is here to help, but is not definitive... sorry!
