# Error code E0461

Couldn’t find crate `..` with expected target triple `..`.

Example of erroneous code:

`a.rs`

    #![crate_type = "lib"]

    fn foo() {}

`main.rs`

    extern crate a;

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

`a.rs` is then compiled with `--target powerpc-unknown-linux-gnu` and `b.rs` with `--target x86_64-unknown-linux-gnu`. `a.rs` is compiled into a binary format incompatible with `b.rs`; PowerPC and x86 are totally different architectures. This issue also extends to any difference in target triples, as `std` is operating-system specific.

This error can be fixed by:

- Using Cargo, the Rust package manager, automatically fixing this issue.
- Recompiling either crate so that they target a consistent target triple.
