Hi Ciro,

I met the below problem and I searched the issues which don't include this one. You can take a look below error:

Thanks a lot.

QEMU moved to ninja apparently, can you try:

sudo apt install ninja-build

Also added at https://github.com/cirosantilli/linux-kernel-module-cheat/commit/f350d28a808dbf0dd374197bfb33e6940da093c9 now.

You can close this issuse.

It should be noted, on MacOS, you can install this package using brew install ninja.
