Description
Code
Full project to reproduce this bug is at https://github.com/anatawa12/rust-1.82-linker-regression
I tried to link .a file at $OUT_DIR/testlib.a with the following build.rs code.
fn main() {
let out_dir = PathBuf::from(std::env::var_os("OUT_DIR").unwrap());
std::fs::create_dir_all(&out_dir).unwrap();
let object = out_dir.join("testlib.o");
let archive = out_dir.join("testlib.a");
// buiid code here
println!(
"cargo:rustc-link-search=native={path}",
path = out_dir.display()
);
println!("cargo:rustc-link-lib=static:+verbatim=testlib.a");
}I ran cargo +stable test, linker reported ld: library 'testlib.a' not found, but with rust 1.81.0 (cargo +1.81.0 test) no linker error was reported.
Rust 1.82.0 on linux works well AFAIK (not tested with this code above, but works with real-world case I found this regression)
