//! Regression test for [rustc doesn't handle relative symlinks to libraries
|
|
//! #13890](https://github.com/rust-lang/rust/issues/13890).
|
|
//!
|
|
//! This smoke test checks that for a given library search path `P`:
|
|
//!
|
|
//! - `rustc` is able to locate a library available via a symlink, where:
|
|
//! - the symlink is under the directory subtree of `P`,
|
|
//! - but the actual library is not (it's in a different directory subtree).
|
|
//!
|
|
//! For example:
|
|
//!
|
|
//! ```text
|
|
//! actual_dir/
|
|
//! libfoo.rlib
|
|
//! symlink_dir/ # $CWD set; rustc -L . bar.rs that depends on foo
|
|
//! libfoo.rlib --> ../actual_dir/libfoo.rlib
|
|
//! ```
|
|
//!
|
|
//! Previously, if `rustc` was invoked with CWD set to `symlink_dir/`, it would fail to traverse the
|
|
//! symlink to locate `actual_dir/libfoo.rlib`. This was originally fixed in
|
|
//! <https://github.com/rust-lang/rust/pull/13903>.
