Is there a ncursesw package in homebrew?

Looks like supporting macos might be a bit more complicated : /

I tried a target-specific Cargo.toml in the macos branch, can you have a try at it and see if it makes things better? Thanks!

You can specify the dependency in Cargo.toml:

[dependencies.cursive]
git = "https://github.com/gyscos/Cursive"
branch = "macos"

Hi there. I've had the same issue with ncursesw lib, and macos branch didn't solve the problem, unfortunately.
However, I've switched to termion backend, and everything seems to be working fine.

Looks like the reason the macos branch still fails is rust-lang/cargo#1197
:(

This actually worked for me. I was having the WORST time trying to fix this. But this compiled and so far seems to work.

Some newer versions of cargo may have a better dependency resolving system? @mmiecz , could you try upgrading cargo and see if it changes anything?

Hi, I've updated cargo, and everything seems to be working fine now. Thanks!

Actually, I've run into some really weird problem. Whenever I try to compile example code without any changes, Cursive gets recompiled every time. Sometimes it gets recompiled without any error, and sometimes old error comes back:

This looks like cargo error.

That's weird indeed. Maybe the cargo cache got messed up with an upgrade? cargo clean could help?
