Answer 1 · 2017-11-20T05:35:48.000Z

Do you have ncursesw installed? (the wide version)

EDIT: Whoops, I got confused by https://www.rpmfind.net/linux/rpm2html/search.php?query=pkgconfig(ncursesw), looks like fedora only has ncurses-devel

Answer 2 · 2017-11-22T01:20:51.000Z

I couldn't it in the fedora package list

dnf search ncursesw

It also fails for me running on ubuntu with libcurses5, libcurses5-dev, libcursesw5 and libcursesw5-dev installed.

Answer 4 · 2017-11-22T22:56:18.000Z

I can see in the output of my build that it is not even trying ncursesw: -l ncurses

Answer 5 · 2017-11-22T22:59:05.000Z

And it doesn't show up here: https://github.com/jeaye/ncurses-rs/blob/master/build.rs#L48

Answer 6 · 2017-11-22T23:00:32.000Z

This solves for this lib itself: https://github.com/jeaye/ncurses-rs/blob/master/Makefile#L23

So I need that on my own project?

Answer 7 · 2017-11-22T23:34:13.000Z

So on linux you need this:

[dependencies.ncurses]
version = "*"
features = ["wide"]

On OSX it works without that because the library name happens to be the same.
