Compiling error

[Zardoz89]

I'm trying to compile the actual head of the repo ( commit e67e03605d61881180c390dbc44b88430ebbd23d ) , and I'm getting this errors on Ubunyu 17.10 :

The documentation suggests that RefCell replace has been stable since rust 1.24. Sounds like you need to update your rust compiler.

Yes, please use latest stable rust

As a side note, on Ubuntu, make sure sudo commands use the same rustc version of your user. Running sudo -E env "PATH=$PATH" make install will preserve your user $PATH so you'll be sure you'll use the same rustc and not the one found in /usr/bin, as sudo commands don't load a shell (and .profile) but use the secure_path directive in /etc/sudoers file.

Humm... Rust compiler version looks that evolves quickly, not ?? I installed rust like a few month ago. Compared against c++ or DLang, it moves very quickly
