notty-encoding fails to build on OSX 10.11.6

[michael-grunder]

Hi,

I'm trying to compile notty and have run into an error building the encoding package. Here is the output from my build:

I was able to find a few places on the net mentioning this error but unfortunately I don't know nearly enough about rust to figure out a solution. Hopefully I'm not missing something totally obvious here :smiley:

Edit: I get the same error in Ubuntu.

i can second that on debian-stretch

@michael-grunder this seems like an upstream nightly feature being under development https://github.com/rust-lang/rust/issues/29646

I also get the same error compiling on Arch linux:

[mexus]

so.. could the project be considered as an abandoned one?

[tbodt]

I don't wanna believe it 😢

@withoutboats

[matthewmummert5]

Yup, I'd say it's abandoned. The last commit to an actual source file was 10 months ago. It also doesn't compile anymore. I guess that's just part of the cost of developing on Rust nightly.
