| Plugin `..` only found in rlib format, but must be available in dylib format. | ||
|
|
||
| Erroronous code example: | ||
|
|
||
| `rlib-plugin.rs` | ||
| ```ignore (needs-linkage-with-other-tests) | ||
| #![crate_type = "rlib"] | ||
| #![feature(rustc_private)] | ||
| extern crate rustc_middle; | ||
| extern crate rustc_driver; | ||
| use rustc_driver::plugin::Registry; | ||
| #[no_mangle] | ||
| fn __rustc_plugin_registrar(_: &mut Registry) {} | ||
| ``` | ||
|
|
||
| `main.rs` | ||
| ```ignore (needs-linkage-with-other-tests) | ||
| #![feature(plugin)] | ||
| #![plugin(rlib_plugin)] // error: plugin `rlib_plugin` only found in rlib | ||
| // format, but must be available in dylib | ||
| fn main() {} | ||
| ``` | ||
|
|
||
| The compiler exposes a plugin interface to allow altering the compile process | ||
| (adding lints, etc). Plugins must be defined in their own crates (similar to | ||
| [proc-macro](../reference/procedural-macros.html) isolation) and then compiled | ||
| and linked to another crate. Plugin crates *must* be compiled to the | ||
| dynamically-linked dylib format, and not the statically-linked rlib format. | ||
| Learn more about different output types in | ||
| [this section](../reference/linkage.html) of the Rust reference. | ||
|
|
||
| This error is easily fixed by recompiling the plugin crate in the dylib format. |

| Found possibly newer version of crate `..` which `..` depends on. | ||
|
|
||
| Consider these erroneous files: | ||
|
|
||
| `a1.rs` | ||
| ```ignore (needs-linkage-with-other-tests) | ||
| #![crate_name = "a"] | ||
| pub fn foo<T>() {} | ||
| ``` | ||
|
|
||
| `a2.rs` | ||
| ```ignore (needs-linkage-with-other-tests) | ||
| #![crate_name = "a"] | ||
| pub fn foo<T>() { | ||
| println!("foo<T>()"); | ||
| } | ||
| ``` | ||
|
|
||
| `b.rs` | ||
| ```ignore (needs-linkage-with-other-tests) | ||
| #![crate_name = "b"] | ||
| extern crate a; // linked with `a1.rs` | ||
| pub fn foo() { | ||
| a::foo::<isize>(); | ||
| } | ||
| ``` | ||
|
|
||
| `main.rs` | ||
| ```ignore (needs-linkage-with-other-tests) | ||
| extern crate a; // linked with `a2.rs` | ||
| extern crate b; // error: found possibly newer version of crate `a` which `b` | ||
| // depends on | ||
| fn main() {} | ||
| ``` | ||
|
|
||
| The dependency graph of this program can be represented as follows: | ||
| ```text | ||
| crate `main` | ||
| | | ||
| +-------------+ | ||
| | | | ||
| | v | ||
| depends: | crate `b` | ||
| `a` v1 | | | ||
| | | depends: | ||
| | | `a` v2 | ||
| v | | ||
| crate `a` <------+ | ||
| ``` | ||
|
|
||
| Crate `main` depends on crate `a` (version 1) and crate `b` which in turn | ||
| depends on crate `a` (version 2); this discrepancy in versions cannot be | ||
| reconciled. This difference in versions typically occurs when one crate is | ||
| compiled and linked, then updated and linked to another crate. The crate | ||
| "version" is a SVH (Strict Version Hash) of the crate in an | ||
| implementation-specific way. Note that this error can *only* occur when | ||
| directly compiling and linking with `rustc`; [Cargo] automatically resolves | ||
| dependencies, without using the compiler's own dependency management that | ||
| causes this issue. | ||
|
|
||
| This error can be fixed by: | ||
| * Using [Cargo], the Rust package manager, automatically fixing this issue. | ||
| * Recompiling crate `a` so that both crate `b` and `main` have a uniform | ||
| version to depend on. | ||
