Why are you attempting to compile qemu for a non-hosted (aka bare metal) configuration? That is certainly not a supported thing to do. We require POSIX (or Win32) at a minimum. I can only presume that you're intending a hosted configuration, and using a cross-compiler that doesn't actually match up. What is the intended host (and libc if this is for Linux, since there are at least 3)? > It's complaining about > MADV_NOHUGEPAGE not being defined.

I'm leaning toward the latter, but you're not giving much in the way of a hint. r~
