Is there any way to build on MacOS?

[gcavalcante8808]

I'm trying to build the unfp on MacOS/Darwin, but following errors was returned:

I'm using rustc 1.37.0-nightly (37d001e4d 2019-05-29). Thanks in advance.

macos-fix branch will fix it. Would you try it out?

@pfpacket Thanks for the response. Ill try it on monday. Thanks for the tip.

help: you can convert an `u32` to `u16` and panic if the converted value wouldn't fit

Considering rust-9p specifically targets 9p2000.L, which is Linux specific, isn't it expected that building for MacOS won't work?

You can run 9P2000.L file servers on macOS and still 9P2000.L clients such as v9fs can connect to them and mount them, which means something.

Ah ok, then disregard my comment :)
