Fix Linux compilation #24

Closed vit9696 closed 2 years ago

vit9696 commented 2 years ago

memfd_create is provided by all relatively modern Linux distributions. Compiling QEMU on Debian 10 gives me a compiler error "static declaration follows non-static declaration for memfd_create".

Does this still compile on Ubuntu 18.04?

vit9696 commented 2 years ago

Yes.

Ok. Let's hope that it'll also build in my multi-platform environment, including Raspberry Pi OS. (Actually Ubuntu 18 running inside Docker on top of Raspberry Pi OS 32/64).
