run-make-support: set rustc dylib path for cargo wrapper by jchecahi · Pull Request #140745 · rust-lang/rust (original) (raw)
Some run-make tests invoke Cargo via run_make_support::cargo(), but fail to execute correctly when rustc is built without rpath. In these setups, runtime loading of rustc’s shared libraries fails unless the appropriate dynamic library path is set manually.
This commit updates the cargo() wrapper to call set_host_compiler_dylib_path(), aligning its behavior with the existing rustc() wrapper:
| fn setup_common() -> Command { |
|---|
| let mut cmd = Command::new(rustc_path()); |
| set_host_compiler_dylib_path(&mut cmd); |
| cmd |
| } |
This ensures that Cargo invocations during tests inherit the necessary dylib paths, avoiding errors related to missing shared libraries in rpath-less builds.
Fixes part of #140738
