| More than one function was declared with the `#[start]` attribute. |
| |
| Erroneous code example: |
| |
| ```compile_fail,E0138 |
| #![feature(start)] |
| |
| #[start] |
| fn foo(argc: isize, argv: *const *const u8) -> isize {} |
| |
| #[start] |
| fn f(argc: isize, argv: *const *const u8) -> isize {} |
| // error: multiple 'start' functions |
| ``` |
| |
| This error indicates that the compiler found multiple functions with the |
| `#[start]` attribute. This is an error because there must be a unique entry |
| point into a Rust program. Example: |
| |
| ``` |
| #![feature(start)] |
| |
| #[start] |
| fn foo(argc: isize, argv: *const *const u8) -> isize { 0 } // ok! |
| ``` |
