Build error for v0.15.0 on MacOS

[daeho-ro]

Hello, this is a homebrew maintainer and I got some error during build on MacOS.

  error[E0425]: cannot find function `prctl` in crate `libc`

This is expected to use only on Linux.

Can you check?
Thanks,

ref

• arp-scan-rs 0.15.1 Homebrew/homebrew-core#254826

[Saluki]

Hi @daeho-ro 👋

Thanks for the quick feedback !
Could you please try the build again on the 0.15.1 release ? The component that checks for capabilities has been isolated in a linux target.

It seems like you are not able to fetch any of the crates (unresolved import csv, pnet_datalink, ipnetwork, dns_lookup, ...).
Could you describe the commands that you are using ? Do the v0.15.1 pre-built binaries work in your environment ?

[daeho-ro]

Oh.. maybe cloudflare issue, I will try later.
