PowerPC, MIPS and NetBSD problem

[Trojan295]

Hello,

I'm trying to compile notify 4.0.3 on a few different environments and looks it's failing on some (https://travis-ci.org/jedisct1/flowgger/builds/351310716).

For NetBSD (x86_64-unknown-netbsd) it looks like an issue with a dependency (https://github.com/alexcrichton/filetime):

error[E0425]: cannot find value `utimensat` in module `libc`
 --> /cargo/registry/src/github.com-1ecc6299db9ec823/filetime-0.1.15/src/unix/utimensat.rs:8:45

  |                                             ^^^^^^^^^ did you mean `futimens`?
help: possible candidate is found in another module, you can import it into scope

mips, powerpc and s390x, could be failing due to some old dependencies (mio 0.5.1 and nix 0.5.1), which didn't support such architectures (https://docs.rs/crate/nix/0.5.1/source/src/sys/syscall.rs):

error[E0432]: unresolved import `self::arch`

Firstly, thanks for trying on such architectures! v5 is going to be built on a wider range of archs, but up until then I'm mostly relying on people like you testing it out.

IIRC, upgrading mio requires some pretty large changes, so I didn't elect to do it on the v4 branch. If you want to take a crack at it, I'd welcome any PR, though.

For filetime, I think this is the same issue? alexcrichton/filetime#19 It seems it's a libc issue instead. Try filing with them?

[Trojan295]

OK, the problem with NetBSD is solved, we had libc locked to 0.2.31 and after an update to 0.2.39 the issue disappeared.

I will see what I can do with this update of mio, although I'm not so experienced with Rust.. but willing to learn! :)

[passcod]

This will be fixed when v5 releases due to it using a newer mio.

I believe this is now fixed with #162 (in 4.0.6)
