# Error code E0462

Found `staticlib` `..` instead of `rlib` or `dylib`.

Consider the following two files:

`a.rs`

    #![crate_type = "staticlib"]

    fn foo() {}

`main.rs`

    extern crate a;

    fn main() {
        a::foo();
    }

Crate `a` is compiled as a `staticlib`. A `staticlib` is a system-dependant library only intended for linking with non-Rust applications (C programs). Note that `staticlib`s include all upstream dependencies (`core`, `std`, other user dependencies, etc) which makes them significantly larger than `dylib`s: prefer `staticlib` for linking with C programs. Learn more about different `crate_type`s in this section of the Reference.

This error can be fixed by:

- Using Cargo, the Rust package manager, automatically fixing this issue.
- Recompiling the crate as a `rlib` or `dylib`; formats suitable for Rust linking.
