Error code E0454
A link name was given with an empty name.
Erroneous code example:
#![allow(unused)] fn main() { #[link(name = "")] extern "C" {} // error: `#[link(name = "")]` given with empty name }
The rust compiler cannot link to an external library if you don't give it its name. Example:
#[link(name = "some_lib")] extern "C" {} // ok!
