Can't run examples

[Eratosthenes]

make example makes my computer start whirring like a jet about to take off, but ultimately doesn't seem to do anything else. I'm on Debian 6.1.27-1 (2023-05-08) x86_64 GNU/Linux.

If ya'll can provide instructions for making this work, maybe--I dunno, this is a radical thought, but maybe add instructions for installing stuff and running it to the readme, on the off chance that this isn't broken on your machine too--that would be great.
