Thanks for the report! I think if we make a release this will get fixed, as we've bumped the libc requirement to 0.2 in the meantime, which should have libc::PATH_MAX: https://github.com/rust-lang/libc/blob/a64ee24718c0289b82a77d692cf56f8a1226de51/src/unix/bsd/mod.rs#L113

Filed #269 re making a release.

Ah, that makes sense. Thanks!

Attempting to compile this on FreeBSD 10.3, I'm getting

To learn more, run the command again with --verbose.

Not sure if this belongs in another issue or not so posting here for now.

Looks like it's being sorted in #396

[beatgammit]

This now works for me. I've built and run my code on FreeBSD 10.3-RELEASE that uses mio and the latest master works for me. Another has commented in the mio repository that it also works on 11-CURRENT, so I think FreeBSD compat is covered for now.

How do I request a release? Should I open a separate issue for making a release a la #269? I'm willing to test on OpenBSD if that's a blocker.

I believe this has been resolved as of release 0.8.1.
